Best Shopify Size Chart Apps in 2026 (Compared, Scored & Ranked)

Shopify merchants selling clothing, footwear, accessories, or any product that comes in sizes face a quiet but costly problem: shoppers who are not sure about sizing do not buy, and shoppers who guess wrong return the product. A well-placed size chart removes that hesitation. It answers the question "will this fit me?" before the customer has to ask, and it makes the purchase feel lower risk.

The good news is that you do not need to build size charts manually or embed confusing image files. A dedicated Shopify size chart app creates a clean, mobile-responsive chart display linked directly to your products. The best apps go further by offering AI-powered fit recommendations, unit conversion, and detailed measurement guides that help shoppers choose confidently on the first try.

How We Evaluated the Best Shopify Size Chart Apps

We reviewed each app using publicly available sources: the Shopify App Store listing, the developer's own website, and a representative sample of merchant reviews (recent, positive, and critical). No apps were installed or tested on a live store. Every data point, pricing tier, and feature claim comes from the App Store listing or verified merchant experience reported in reviews.

Each app was scored out of 10 across five dimensions:

• Pricing and Value: Free plan availability, price relative to features delivered, and fairness for small stores at growth stages.
• Feature Richness: Depth and breadth of features versus what merchants in this category typically need.
• Built for Shopify and Integration: Whether the app holds the Built for Shopify badge, quality of native Shopify integration, theme editor support, and Shopify 2.0 compatibility.
• Ease of Use (UI/UX): Setup effort, clarity of the admin experience, and quality of onboarding documentation.
• Support and Reputation: App Store rating, review volume, support responsiveness cited by merchants, and developer track record.

Overall score = average of the 5 dimension scores, rounded to one decimal. Apps are ranked from highest to lowest overall score.

1. MP Size Chart and Size Guide: Best for Non-Technical Merchants

MP Size Chart and Size Guide (formerly listed under the Avada Commerce brand, now managed by Shopplaza) is the highest-rated option in this category with a 5.0/5 rating across 819 reviews. It combines an accessible free tier with a fast, guided setup experience and an AI-powered size recommender that scales as your store grows. For merchants who want a size chart solution that works professionally right out of the box, without a learning curve, MP Size Chart earns the top position.

Pricing and Value: 8.5/10

The Starter plan is free and includes 3 published size charts, 10 AI recommendation requests, and access to 30+ industry-specific templates. Paid plans start at $6.95/month (Growth), with annual billing available at a 17% discount. Each tier adds more AI requests and chart publishing slots. The value proposition is strong for stores of any size: zero cost to evaluate, transparent pricing to scale up.

Feature Richness: 8.5/10

MP Size Chart provides 30+ templates covering apparel, footwear, accessories, and more. The AI size recommender helps customers find their fit through a guided quiz, reducing size-related hesitation. Bulk CSV import, 20+ language support with automatic unit conversion, standalone sizing pages, and Shopify 2.0 app block compatibility round out a comprehensive feature set. The only gap relative to top-tier competitors is that AI request volume is capped by plan, which can limit high-traffic stores on the base paid tier.

Built for Shopify and Integration: 9.0/10

MP Size Chart holds the Built for Shopify badge, confirming it meets Shopify's performance, privacy, and code quality standards. Full Shopify 2.0 app block support means charts can be placed and customized directly through the Shopify theme editor without touching code. Integration is clean and stable across themes.

Ease of Use: 9.0/10

The app consistently receives praise from merchants with no technical background. One merchant reported going live with charts within 12 hours of having their sizing data ready. The no-code setup, 30+ ready templates, and automatic unit conversion all reduce the time between installing the app and seeing charts live on product pages.

Support and Reputation: 9.0/10

A 5.0/5 average across 819 reviews is an exceptionally strong signal, particularly given the review volume. Support is described as "extremely professional" and fast to respond even on edge-case implementation questions. The main caveat is that the app is relatively new under the Shopplaza branding, so long-term reliability data beyond 1-2 years is limited.

Pros:

• Perfect 5.0/5 rating with 819 reviews
• Generous free plan with 30+ templates and AI requests
• Built for Shopify badge with Shopify 2.0 app block support
• Fast, no-code setup with dedicated standalone sizing page
• 20+ language support with automatic unit conversion

Cons:

• AI request volume is plan-capped (high-traffic stores may need to upgrade)
• Relatively recent under current developer; limited long-term track record
• Free plan limited to 3 published charts

Pricing:

• Starter: Free (3 charts, 10 AI requests, 30+ templates)
• Growth: $6.95/month or $69.50/year (up to 10 charts, 800 AI requests)
• Pro: $12.95/month or $129.50/year (unlimited charts, higher AI request quota)
• Advanced: $24.95/month or $249.50/year (unlimited charts, priority support)

Scores: Pricing and Value 8.5 | Feature Richness 8.5 | Built for Shopify 9.0 | Ease of Use 9.0 | Support and Reputation 9.0 | Overall: 8.8/10

2. Smart Size Chart and Fit Finder: Best for Measurement-Based Fit Guidance

Smart Size Chart and Fit Finder by SmartSize stands out for one feature that no other app in this roundup replicates: it remembers a customer's body measurements across browsing sessions. Instead of re-entering measurements every visit, returning shoppers are guided directly to their recommended size based on stored data. Merchants have cited return rate reductions as high as 80% from this approach. For fashion brands and apparel stores where fit is personal, Smart Size Chart is the strongest option in the category.

Pricing and Value: 7.0/10

The free plan is available, and annual billing offers a 20% discount. However, the lowest paid tier starts at $9/month, which is slightly above what comparable competitors charge at entry level. The pricing reflects a premium feature set, but small stores testing the app may feel the starting cost before they have enough traffic to measure the return-reduction benefit.

Feature Richness: 9.0/10

Smart Size Chart offers AI-powered chart creation from images or templates, a persistent measurement memory quiz, 25+ language AI translation, multi-tab charts, international sizing standard mapping, and automatic cm/inch unit conversion. The quiz-based fit finder is designed so customers never need a tape measure, which meaningfully reduces friction for shoppers who would otherwise skip sizing guidance.

Built for Shopify and Integration: 9.0/10

The app holds the Built for Shopify badge and integrates cleanly with the Shopify admin. Drag-and-drop chart placement with automatic button insertion reduces setup time. Theme compatibility has been stable across merchant reports.

Ease of Use: 8.5/10

Merchants describe the app as "simple to use, but powerful." The drag-and-drop editor and automatic button placement reduce configuration overhead. The quiz setup for the fit finder adds a small amount of configuration, but the result is a significantly more engaging customer experience than a static chart. Templates for adults, lingerie, kids, and pets cover the most common apparel sizing scenarios.

Support and Reputation: 9.0/10

Smart Size Chart holds a 5.0/5 rating with 130 reviews, with 96% of reviews at five stars. Specific support staff are named in multiple positive reviews for going above and beyond. The 80% return reduction cited by one merchant is an unusually strong outcome claim, but consistent with the product's focus on body-measurement-based recommendations rather than generic S/M/L guidance.

Pros:

• Persistent customer measurement memory reduces repeat friction
• Quiz-based fit finder requires no tape measure
• 96% five-star rating across 130 reviews
• 25+ language AI translation
• Built for Shopify badge with clean admin integration

Cons:

• Starting paid plan at $9/month is slightly above average for the category
• Review count (130) is smaller than top-reviewed competitors
• Free plan feature scope is not detailed prominently in the listing

Pricing:

• Free: $0/month
• Starter: $9/month or $86.40/year
• Growth: $12/month or $115.20/year
• Pro 100: $19/month or $182.40/year

Scores: Pricing and Value 7.0 | Feature Richness 9.0 | Built for Shopify 9.0 | Ease of Use 8.5 | Support and Reputation 9.0 | Overall: 8.5/10

3. CSC - Size Chart and Size Guide: Best for Guided, White-Glove Setup

CSC: Size Chart and Size Guide by TaskHusky competes on something the other apps do not prominently offer: a "done-for-you" setup included even on the free plan. The developer's team actively assists new merchants with initial chart configuration rather than leaving them to figure it out alone. For store owners who want professional results without spending hours learning a new tool, CSC's hands-on approach makes it the easiest app to get running in the category.

Pricing and Value: 8.5/10

The free plan includes 2 published size charts, no watermark, and the included setup assistance. Paid plans start at $6.99/month with a 14-day free trial. The AI size recommendation engine unlocks on the Advanced plan ($14.99/month), which is a meaningful feature step-up for stores where individual body measurements matter. The "done-for-you" setup on the free plan delivers real value that other apps charge for or do not offer at all.

Feature Richness: 7.5/10

CSC includes 18 ready-made templates covering shirts, pants, dresses, shoes, rings, and more. Auto-assign by collection, vendor, or product type saves time for larger catalogs. AI size recommendations (Advanced tier), automatic unit conversion, and multi-language support cover the core category needs. The feature set is solid but slightly narrower in depth than Kiwi or SmartSize at the top end.

Built for Shopify and Integration: 8.5/10

CSC holds the Built for Shopify badge and supports Shopify 2.0 app blocks. Theme integration is stable and merchant-reported performance is consistently good over multi-year use periods.

Ease of Use: 9.0/10

The done-for-you setup differentiator translates directly to a better first-day experience. Merchants praise the multiple ways to assign charts to products without touching code. The developer actively resolves display issues and layout edge cases, which reduces the support burden on the merchant side.

Support and Reputation: 8.5/10

CSC holds a 5.0/5 rating across 93 reviews. The review count is the smallest in this group among apps above 7.0 overall, but the quality of individual reviews is high. Merchants cite same-day responses and staff who personally guide setup. Long-term merchants (2+ years) report consistent reliability.

Pros:

• Done-for-you setup included on the free plan
• No watermark on any plan, including free
• 5.0/5 rating with named-staff support praise
• Built for Shopify badge
• AI recommendations on Advanced tier

Cons:

• Free plan limited to 2 published charts
• AI recommendations require Advanced plan ($14.99/month)
• Smaller review base (93 reviews) compared to established competitors

Pricing:

• Free: $0/month (2 charts, no watermark, setup assistance)
• Grow: $6.99/month (unlimited charts, 14-day trial)
• Advanced: $14.99/month (500 AI recommendations, multi-language, 14-day trial)
• Plus: $29.99/month (unlimited AI recommendations, 14-day trial)

Scores: Pricing and Value 8.5 | Feature Richness 7.5 | Built for Shopify 8.5 | Ease of Use 9.0 | Support and Reputation 8.5 | Overall: 8.4/10

4. BF Size Chart and Size Guide: Best for Long-Term Reliability

BF Size Chart and Size Guide by Relentless Apps earns a strong score not through headline features but through something harder to fake: a consistent track record of quiet, reliable performance over years of real merchant use. Multiple merchants in reviews cite 3 to 7 years of continuous use without meaningful complaints. No watermark on any plan, including the free tier, is a standout free-plan differentiator. If you want a size chart tool that just works, loads fast, and stays out of your way, BF Size Chart delivers.

Pricing and Value: 9.0/10

BF Size Chart earns the highest pricing score in this roundup. The free plan includes 3 size charts with no watermark and unlimited product connections, making it the most generous no-cost entry in the category. The Premium plan ($5.99/month) covers up to 100 charts, and the Unlimited plan ($11.99/month) adds unlimited charts and cm/inch conversion. Annual billing is available across all paid plans.

Feature Richness: 7.0/10

BF Size Chart does not offer an AI recommender or a customer fit quiz. What it provides, it provides cleanly: customizable text and images, mobile-responsive display, import/export, multiple charts per product, and category support for t-shirts, shoes, jewelry, and body measurements. It is a utility tool, not a conversion platform. Stores that already have clear sizing and just need reliable display will find this sufficient; stores that want active fit guidance will need to look elsewhere.

Built for Shopify and Integration: 8.5/10

The app carries the Built for Shopify badge and has demonstrated reliable theme compatibility across a broad range of stores over multiple years. Performance impact is described by merchants as minimal, which matters for stores prioritizing page speed.

Ease of Use: 9.0/10

Setup time is consistently described as 10 to 15 minutes. The interface is direct, the chart creation workflow is clear, and the product linking is straightforward. The app does not try to do too much, which makes the interface easy to navigate without training.

Support and Reputation: 8.5/10

BF Size Chart holds a 4.7/5 rating across 128 reviews. Support response times are cited in reviews as "within minutes." Long-term merchant retention is one of the strongest trust signals in this evaluation: multiple merchants describe using the app for 5 to 7 years, which is rare in the Shopify app ecosystem and a strong indicator of stability.

Pros:

• No watermark on the free plan (3 charts included)
• Multiple merchants cite 3 to 7 years of reliable use
• Lowest pricing in the paid tier for full chart coverage ($5.99/month)
• Built for Shopify badge
• Minimal performance impact reported by merchants

Cons:

• No AI recommender or fit quiz
• Unit conversion (cm/inches) is on the highest plan only
• No multi-language support
• Feature set is deliberately limited, which may not suit complex sizing needs

Pricing:

• Basic: Free (3 charts, no watermark, unlimited product connections)
• Premium: $5.99/month or $59.99/year (up to 100 charts, 14-day trial)
• Unlimited: $11.99/month or $119.99/year (unlimited charts, unit conversion, 14-day trial)

Scores: Pricing and Value 9.0 | Feature Richness 7.0 | Built for Shopify 8.5 | Ease of Use 9.0 | Support and Reputation 8.5 | Overall: 8.4/10

5. Kiwi Size Chart and Recommender: Best for AI Recommendation Depth

Kiwi Size Chart and Recommender by Staytuned holds the largest review count in this comparison at 1,098 reviews and a 4.8/5 rating. It is the most feature-complete option in the category, offering 22 pre-built templates, a full AI size recommendation engine, 22-language support, Google Analytics integration, and CSV import. However, Kiwi ranks fifth overall because of a significant pricing model issue: the developer introduced usage-based billing that can sharply increase monthly costs for growing stores, which has generated strong merchant criticism.

Pricing and Value: 6.5/10

Kiwi has a free plan (3 size charts with watermark) and paid plans starting at $7.99/month. The core problem is that Kiwi moved to a usage-based pricing model at higher tiers, which means costs scale with order volume rather than being predictable flat rates. Merchants who had been paying $5 to $7/month reported charges jumping to over $100/month after a traffic increase. The developer also does not allow data export, which creates migration risk if a merchant decides to switch. These two issues lower the pricing score significantly despite a reasonable headline rate.

Feature Richness: 9.5/10

Kiwi earns the highest feature score in this roundup. The AI recommendation engine covers multiple body measurement types. The 22-language support with auto-translation (buttons and headers) serves international stores. 22 pre-built templates cover apparel, footwear, accessories, and more. CSV and image import, Google Analytics integration, and automated unit conversion based on customer location are all included on paid plans. The recommender can be configured to prioritize different measurements per product type.

Built for Shopify and Integration: 9.0/10

Kiwi holds the Built for Shopify badge and is Shopify 2.0 compatible. Integration quality is consistently praised by long-term merchants, with clean display across a wide range of themes.

Ease of Use: 8.0/10

Basic chart setup is straightforward. Configuring the full AI recommender involves more steps than simpler alternatives, which adds time for merchants who want the complete feature set. The interface is well-designed but does not offer a "done-for-you" option like CSC.

Support and Reputation: 8.0/10

The 4.8/5 rating with 1,098 reviews is a strong baseline. Support quality is frequently praised for technical responsiveness. However, the pricing model controversy and the explicit refusal to export merchant data have generated a pattern of frustrated long-term merchants. The reputation is positive but carries real risks for stores that rely on the platform long-term.

Pros:

• Most comprehensive AI recommendation engine in the category
• 1,098 reviews at 4.8/5 (largest review base)
• 22-language support with automated unit conversion by location
• 22 pre-built templates and Google Analytics integration
• Built for Shopify badge

Cons:

• Usage-based pricing can spike dramatically as store traffic grows
• No data export, making migration very difficult
• Watermark on the free plan
• Language translation applies to interface only, not chart content

Pricing:

• Free: $0/month (3 charts, watermark)
• Premium: $7.99/month (10 charts, no watermark, 14-day trial)
• Plus: $14.99/month (20 charts, 10 custom recommenders, analytics)
• Ultimate: $26.99/month (unlimited, 22-language support)
• Note: Usage-based pricing applies at higher volumes; costs can exceed listed rates

Scores: Pricing and Value 6.5 | Feature Richness 9.5 | Built for Shopify 9.0 | Ease of Use 8.0 | Support and Reputation 8.0 | Overall: 8.2/10

6. ESC Size Charts: Best for Near-Free Simplicity

ESC Size Charts by Eastside Co (formerly marketed as "Size Matters") is the original budget option in the Shopify size chart category. It built a loyal user base through straightforward functionality at near-zero cost. The app still works well for basic chart display, but it now lags meaningfully behind better-supported and more feature-rich competitors at similar price points. Its biggest issue is support quality: multiple merchants report no response to emails, which is a serious concern for a tool that lives on your product pages.

Pricing and Value: 8.0/10

ESC earns a solid pricing score because its value at cost is real. The Basic plan is free with up to 3 charts, mobile-responsive display, and image/text customization. The Premium plan costs just $4.99/month, making it the cheapest paid option in this roundup. The value is there if the app functions as expected; the risk comes when it does not and support is unavailable.

Feature Richness: 6.0/10

ESC provides the fundamentals: chart creation with images and text, Shopify 2.0 / app blocks compatibility, assignment by tags, collections, products, vendors, or product type, drag-and-drop editing, custom CSS support, and import/export on Premium. There is no AI recommender, no fit quiz, no language support, and no unit conversion. For merchants who need exactly chart display and nothing more, this is adequate. For stores that want to actively guide fit decisions, the feature set falls short.

Built for Shopify and Integration: 7.5/10

ESC holds the Built for Shopify badge and supports Shopify 2.0 app blocks. The integration has been stable for long-term merchants, but it receives a lower integration score than competitors because the app has not kept pace with feature updates that take advantage of newer Shopify capabilities.

Ease of Use: 8.0/10

The app's core strength in this dimension is how simple it is. Setup is routinely described as requiring minutes rather than hours, and the interface presents no unnecessary complexity. For a merchant who knows exactly what they want, ESC gets it done quickly.

Support and Reputation: 5.5/10

ESC's support reputation is its most significant weakness. The 4.1/5 rating (the lowest in this set) reflects a growing pattern of negative experiences: merchants report emailing support with no response for days, unresolved export failures, and disappearing functionality. This support degradation appears to be recent rather than historical. Long-term merchants who used the app under the "Size Matters" brand recall better support experiences. New merchants should factor in limited support availability as a real operational risk.

Pros:

• Cheapest paid plan in the category ($4.99/month)
• Free plan with functional chart display
• Dead-simple setup and interface
• Built for Shopify badge
• Shopify 2.0 / app blocks compatible

Cons:

• Support unresponsiveness is a documented, recurring issue
• Lowest App Store rating in this comparison (4.1/5)
• No AI recommender, fit quiz, or language support
• Import/export limited to Premium plan
• ESC watermark on the free plan

Pricing:

• Basic: Free (up to 3 charts, ESC watermark)
• Premium: $4.99/month (unlimited charts, no watermark, import/export, 7-day trial)

7. GA - Size Chart and Size Guide: Best for Ring and Shoe Specialty Sizing

GA: Size Chart and Size Guide by GoodApps is the only app in this evaluation without the Built for Shopify badge, and it has the smallest review base at 67 reviews. It competes on support speed and a specialty niche: ring and shoe sizing categories that require measurement comparison tools not prominently featured by general-purpose competitors. For merchants who specifically need ring sizing guides or shoe measurement charts and find the other apps insufficient for those use cases, GA offers relevant functionality. For most merchants, the combination of no badge, volume-based pricing confusion, and limited review history makes it a less confident choice than the apps ranked above it.

Pricing and Value: 6.0/10

GA: Size Chart does not offer a free plan for live stores (only for development stores). Paid plans start at $6/month, and the pricing structure is based on order volume tiers (Growth 1/2/3) rather than feature unlocks. This volume-based model has surprised merchants who expected flat feature-based billing. Pricing transparency issues are directly referenced in negative reviews, which reduces the confidence score for this dimension.

Feature Richness: 7.0/10

The app provides pre-designed templates, size variant selectors, ring and shoe specialty guides, measurement comparison charts, floating chart display, full style customization (colors, fonts, custom CSS), collection page compatibility, and analytics tracking. The ring and shoe sizing support is the most differentiated feature. The overall feature set is competitive but does not include an AI recommender or persistent fit memory.

Built for Shopify and Integration: 5.5/10

GA: Size Chart does not carry the Built for Shopify badge, which is a notable absence compared to all other apps in this roundup. The badge signals that an app has met Shopify's quality, performance, and privacy standards. Without it, merchants cannot rely on the same baseline guarantee. Integration conflicts with third-party theme tools have also been reported in reviews.

Ease of Use: 7.5/10

Chart creation and product linking are described as easy in positive reviews. The walkthrough for new users is helpful. However, pricing confusion on signup and the inability to rename cloned size charts reduce the ease-of-use experience, particularly for stores managing larger chart libraries.

Support and Reputation: 7.0/10

The 4.7/5 rating is solid at face value, but the 67-review base means the rating is less statistically meaningful than for apps with 128+ reviews. Support response speed is praised (under 10 minutes in cited examples), and proactive fixes after theme changes are noted. Pricing transparency issues and integration conflicts represent consistent complaint themes.

Pros:

• Specialty ring and shoe sizing support
• Fast support response times (under 10 minutes cited)
• Full style customization including custom CSS
• Analytics tracking included
• Collection page compatibility

Cons:

• No Built for Shopify badge
• No free plan for live stores
• Volume-based pricing tiers are confusing and have surprised merchants
• Smallest review base in this evaluation (67 reviews)
• Integration conflicts with some third-party theme tools

Pricing:

• Free: Development stores only
• Growth: $6/month (7-day trial)
• Growth 2: $12/month (7-day trial)
• Growth 3: $24/month (7-day trial)

Scores: Pricing and Value 6.0 | Feature Richness 7.0 | Built for Shopify 5.5 | Ease of Use 7.5 | Support and Reputation 7.0 | Overall: 6.6/10

Which Shopify Size Chart App Should You Choose?

The right app depends on what your store actually needs. Here is a short guide by use case:

• You want the best overall option with polished setup and a strong free plan: Start with MP Size Chart and Size Guide. The 5.0/5 rating, 819 reviews, generous free tier, and no-code setup make it the lowest-risk choice for most stores.
• Your main goal is reducing returns from wrong-size purchases: Smart Size Chart and Fit Finder is built for this. The persistent measurement memory and no-tape-measure quiz directly address the root cause of size-related returns. One merchant cited 80% return reduction.
• You are non-technical and want someone to help you get started: CSC: Size Chart and Size Guide includes done-for-you setup assistance on the free plan. You do not need to figure it out alone.
• You want a dependable, no-frills tool that will be running well in 5 years: BF Size Chart and Size Guide has multi-year merchant retention data and the highest pricing score in this evaluation. Its free plan has no watermark, and its lowest paid plan is the most affordable for full chart coverage.
• You run a high-volume store and need the deepest AI recommendation engine available: Kiwi Size Chart and Recommender has the most complete feature set in the category. Just make sure you understand the usage-based pricing model before scaling, and note that data export is not available if you ever need to migrate.
• You have very simple sizing needs and want to pay as little as possible: ESC Size Charts at $4.99/month (or free for 3 charts) covers basic display needs. Be aware of the support responsiveness issues before committing.
• You sell rings or footwear and need specialty measurement guides: GA: Size Chart and Size Guide offers the most focused ring and shoe sizing support. Understand the volume-based pricing structure before installing.

For most Shopify merchants starting out, MP Size Chart and Size Guide is the recommended first choice. For stores where fit guidance and return reduction are the primary objectives, Smart Size Chart and Fit Finder is worth the slightly higher starting cost.

Is there a free Shopify size chart app with no watermark?

Yes. BF Size Chart and Size Guide by Relentless Apps offers a free plan with up to 3 size charts and no watermark. CSC: Size Chart and Size Guide also offers no watermark on the free plan with up to 2 published charts. MP Size Chart and Size Guide includes 3 charts on its free Starter plan.

Do Shopify size chart apps work with Shopify 2.0 themes?

All six of the top-ranked apps in this comparison (MP Size Chart, Smart Size Chart, CSC, BF Size Chart, Kiwi, and ESC Size Charts) support Shopify 2.0 app blocks, which means charts can be placed and customized directly through the Shopify theme editor without code. GA: Size Chart and Size Guide does not hold the Built for Shopify badge, so its Shopify 2.0 integration may be less reliable.

What does the Built for Shopify badge mean for size chart apps?

The Built for Shopify badge means the app has met Shopify's standards for performance, privacy, code quality, and merchant experience. Apps with the badge are reviewed by Shopify and must maintain compliance to keep it. In this evaluation, 6 out of 7 apps carry the badge; GA: Size Chart and Size Guide does not. The badge is a useful signal of quality but not a guarantee of fit for every use case.

How much does a Shopify size chart app typically cost?

Most Shopify size chart apps offer a free plan for basic use. Paid plans start between $4.99/month (ESC Size Charts) and $9/month (Smart Size Chart). Mid-range plans with AI recommendations and multi-language support typically run $12 to $15/month. High-volume or enterprise plans can reach $25 to $30/month for unlimited charts and recommendations. Annual billing typically saves 17 to 20% versus monthly rates.

Can a size chart app help reduce Shopify return rates?

Yes. A well-implemented size chart reduces purchase hesitation from shoppers who are unsure about fit and reduces returns from shoppers who chose the wrong size. Apps with AI fit recommenders (MP Size Chart, Smart Size Chart, CSC, Kiwi) go further by actively guiding customers to the right size based on body measurements rather than relying on shoppers to interpret a static chart. Smart Size Chart's persistent measurement memory is specifically designed to minimize return-causing size errors across multiple visits.

Should I use a size chart app that does not have the Built for Shopify badge?

You can, but you should understand the trade-off. The Built for Shopify badge indicates Shopify has reviewed the app for quality, privacy, and integration standards. Apps without the badge may still work well, but they lack that independent review layer. In this evaluation, GA: Size Chart and Size Guide is the only app without the badge. Its absence, combined with the smaller review base and pricing transparency issues, is why it ranks last.
