Top 9 Best Shopify Size Chart Apps for your stores

If you sell clothing, shoes, or anything with a size, you already know the most expensive two words in ecommerce: “didn’t fit.” Shoppers can’t try things on, feel the fabric, or check whether a ring will actually slide on — so they guess. And when they guess wrong, the product comes back.

It adds up fast. According to Coresight Research and Alvanon (2025), size and fit issues drive about 70% of all online apparel returns — making “it didn’t fit” the single biggest reason customers send things back. And returns aren’t cheap: retailers lose roughly $30 for every $100 in returned merchandise (RILA Returns Panel, via Optoro).

The fix is simpler than it sounds: give shoppers clear sizing information before they add to cart. A good Shopify size chart app does exactly that — and the best ones now add AI fit recommendations on top, so customers don’t even have to read the table.

In this guide we compare the 9 best Shopify size chart apps for 2026 — with updated ratings, real pricing, and honest pros and cons — so you can pick the right one whether you sell apparel, footwear, jewelry, or accessories.

Shopify Size Chart Apps: Quick Comparison

Ratings, review counts, and pricing verified on the Shopify App Store as of June 2026. App Store numbers change often — check each listing for the latest.

What is a Shopify size chart app, and why do you need one?

A Shopify size chart app adds sizing guides and measurement tables directly to your product pages. Instead of burying sizing in the product description (or skipping it entirely), the app shows a clean, on-brand size guide right where shoppers decide which size to buy — so they choose correctly the first time.

Modern size chart apps for Shopify usually offer:

• Ready-made templates for tops, bottoms, shoes, kids, jewelry, and more
• AI-powered fit recommendations that suggest a size from a few shopper inputs
• Visual guides with images, icons, and how-to-measure diagrams
• Multi-unit support (inches, centimeters, and international sizing)
• Mobile-optimized display, since most shopping now happens on phones
• Theme integration via Shopify app blocks — no developer required

What a size chart app actually does for your store

You don’t need invented percentages to see the value — the mechanism is straightforward:

• Fewer size-related returns. Size and fit cause ~70% of apparel returns (Coresight & Alvanon, 2025), so clearer sizing targets the #1 return reason at the source.
• More confident checkouts. When shoppers can verify a measurement, they hesitate less and add to cart more.
• Fewer “what size am I?” tickets. A self-serve size guide deflects a large share of pre-sale messages.
• A more professional storefront. A polished, consistent size guide signals that you care about getting the fit right.

Key benefits of a Shopify size chart app

We all know the letdown of ordering clothes online, waiting days for delivery, and then — they don’t fit. A good size chart app is built to prevent exactly that. Here’s what the best ones help you do:

• Reduce returns and exchanges by helping shoppers pick the right size the first time.
• Increase shopper confidence so fit uncertainty stops killing add-to-carts.
• Lift conversions when customers feel sure about the size they’re choosing.
• Improve the product-page experience with clear, accessible sizing.
• Look more professional with on-brand, consistent size guides.
• Cut down support tickets by answering sizing questions before they’re asked.
• Support international shoppers with unit conversion and regional sizing.
• Match your brand through customizable colors, fonts, and layouts.
• Apply automatically to the right products, collections, or tags.

In short, a Shopify size chart app helps both you and your customers. Below are the 9 best options for 2026 — pick the one that fits your catalog and budget.

There’s no single “best” app — the right pick depends on your catalog size, budget, and how much you want AI to do the work. Here’s a quick way to narrow it down.

By store size

• Small stores (< 100 products): Start free with MP Size Chart (templates + AI to try), Pify (free, Built for Shopify), or ESC (clean and simple).
• Medium stores (100–1,000 products): MP Size Chart (bulk import + AI), Kiwi (mature AI recommender), or CSC (one-click generation).

Frequently Asked Questions (FAQ)

1. What is the best size chart app for Shopify stores?

MP Size Chart & Size Guide is our top overall pick. It pairs ready-made templates and deep customization with AI-powered size recommendations, holds a 5.0★ rating on the Shopify App Store, and offers a free plan plus affordable paid tiers — so it scales with stores of any size. For a completely free alternative, Pify Size Charts (also Built for Shopify) is worth a look.

2. How much do Shopify size chart apps cost?

Pricing varies by features:

• Free plans: MP Size Chart, Pify (fully free), ESC, BF, Kiwi, ILM, CSC, Smart Size Chart, and True Fit (free to install).
• Budget tier: ~$4.99–$6.99/month for core premium features.
• Mid tier: ~$9–$15/month for advanced features and AI recommendations.
• Enterprise: True Fit starts around $1,000/month (contact sales).

Most small and mid-size stores find the best value in the $5–$13/month range.

3. Do size chart apps really reduce returns?

Yes — and the logic is well documented. Since size and fit cause about 70% of online apparel returns (Coresight & Alvanon, 2025), giving shoppers clear measurements and AI fit guidance directly targets the #1 reason products come back. The size of the improvement depends on your products and how accurate and detailed your charts are — so keep your sizing data current and product-specific.

4. Can I use multiple size chart apps on the same Shopify store?

It’s technically possible but not recommended. Running two size chart apps at once can cause code conflicts, slow your pages, confuse shoppers with inconsistent charts, and duplicate costs. Choose one app that covers all your product categories instead — for example, MP Size Chart offers templates across apparel, footwear, jewelry, and more.

5. How long does it take to set up a size chart app?

• Basic setup: about 5 minutes for a simple install.
• Full setup: 15–30 minutes to build product-specific charts and style them to your brand.

6. Are size chart apps mobile-friendly?

Yes — all modern Shopify size chart apps are mobile-responsive, which matters because most ecommerce traffic is now on phones. Quality still varies, so test your chosen app on a few devices before launch. MP Size Chart, Smart Size Chart, and Kiwi all offer strong mobile experiences.

7. Can size chart apps help with international customers?

Yes. The better apps support automatic unit conversion (inches/centimeters), international sizing standards (US, UK, EU, Asia), and clear measurement display so global shoppers can buy with confidence. MP Size Chart, Kiwi, and True Fit all handle international sizing well.

The bottom line

If you sell shirts, pants, shoes, hats, rings, or any sized product, your customers want to get the fit right the first time — and so do you. The 9 Shopify size chart apps above all help, in an easy-to-use way that matches your brand. Most have free plans or short trials, so there’s no risk in installing a couple and testing them on your busiest product pages.
