The 7 Best Size Chart Apps for Shopify in 2026
A Size Chart is not a pop-up. It is the numeric half of a purchase. Shoppers also ask how the garment will look on them. Apps that only ship a table leave that half open. Apps that hide the table inside a photo flow leave the size half closed for everyone who never uploads.
We make AI Frame. We are on this list. Read the others as tools for a different job, not as enemies.
How this ranking works
Not “most reviews.” Not “cheapest.” Three jobs:
-
Show a Size Chart next to Size, on every relevant product, in cm and inches.
-
Recommend a size without a tape measure.
-
Show the product on the shopper so look is not a guess.
Kiwi is still in the seven. It earned that. AI Frame is first because fashion stores need job 3 as well as 1 and 2, and those answers have to stay independently reachable.

1. AI Frame: AI Virtual Try‑On & Size Chart best for fashion that needs look & fit
Try On sits on the first product image. Size Chart is a text link next to Size. Estimate my size sits above Add to cart on Starter and above. None of those wait for the others.
Import from photo, PDF, CSV, or a store scan (drafts, live site unchanged). Assign by products, categories, tags, vendor, collections. Body vs garment is required in the editor. Garment charts add fit intent and stretch (0–20%). Shopper units follow location, with a cm / inches toggle.
Plans:
- Free: 10 try-ons, 10 charts, Try-on by AI Frame badge.
- Starter $19.99: Size Recommender, 80 try-ons, 30 charts.
- Growth $59.99: 350 try-ons, 100 charts.
- Advanced $199.99: 1,400 try-ons, unlimited charts.
Trade-off: 20 reviews. Not the installed base Kiwi has. Swimwear: chart yes, try-on no.
2. Kiwi Size Chart & Recommender - best default if you only want a table
4.7 from 1,231 reviews. Image import, description import, auto unit by geo, assignment that follows new products. That catalogue work is why it won the category.
Trade-off: watermark on free. Recommender from $14.99. Order-volume fees on Plus and Ultimate (up to $350 / $700 extra on Kiwi’s own table). Import credits for images. No Virtual Try-On. See 7 Kiwi Size Chart alternatives.
3. MP Size Chart & Size Guide - best like-for-like recommender
5.0 from 875 reviews. Recommendations on the free plan. No usage fee by orders. Free Kiwi migration. Dedicated sizing page.
Trade-off: still a chart app. No try-on on the shopper’s photo.
4. SmartSize - best when the shopper will take a quiz
Chart from an image. “Find my size” remembered across products. 25+ languages.
Trade-off: quiz is on the $19 tier and metered. Pets and kids templates if you do not need them.
5. ScaleChart - best auto units and AI chart build
Location-based units on free. Generate from photo or text. Recommender on free.
Trade-off: paid tier pushes cart upsells. Easy to buy a merchandising suite when you came for a table.
6. Pify - best free Size Chart
No paid plan, no watermark, 40 reviews at 5.0. Hover on the size option.
Trade-off: no recommender. You still need a try-on app if look is the return reason.
7. Jotly - best if you need to prove the chart converts
Add-to-cart tied to the guide on the analytics plan. 123 templates.
Trade-off: no size from height and weight. No try-on.
What “best” is not
A custom CSS editor. Five knobs per measurement. A Size Chart that only opens after a selfie. A recommender that infers a body from a photo — we do not, and you should not.
Shopify’s own data: shoppers who can visualize products convert up to 94% better. That is visualization on the product they buy, not a promise about any one app. Size help is the other half. Zalando measured 10% fewer size-related returns on items with size advice.
Put the chart next to Size. Put Try On on the photo. Let Estimate my size catch everyone who will not measure themselves.
