Notes
A "size chart tool" on Shopify usually means one of two things, and the best choice depends on which problem you're solving:
1. A size chart app shows a measurement table on the product page (popup, tab, or inline). This is what most stores mean by "add a size chart in Shopify." Every tool above does this. If that's all you need, pick on price and how clean the chart looks on mobile — Clean, Prime, and Apps Mav are the cheapest, Avada is free if you already run their apps.
2. A fit recommendation tool (a "fit recommender") asks the shopper a couple of questions — height, weight, usual size, fit preference — and recommends the size most likely to fit. This is what actually moves the needle on returns, because most apparel returns are "wrong size / didn't fit." Tailor Size Guide and Kiwi Sizing both do this; the budget tools don't.
Why Tailor Size Guide leads in 2025: it combines a standard size chart, an AI-driven fit recommender, and made-to-order / custom-measurement capture in one app — and starts at $7.99/mo with a free tier. For a store trying to cut clothing returns rather than just display a table, that's the strongest single tool. Kiwi Sizing is the most established alternative if you only sell standard off-the-rack apparel.
How to choose quickly: just need a chart? Pick the cheapest one that looks good on your theme. Want to reduce returns and recommend sizes? Use a tool with a real fit recommender (Tailor Size Guide or Kiwi). Sell made-to-order or custom-fit garments? Tailor Size Guide is the only one here that captures measurements at checkout.
FAQs
What is the best size chart app for Shopify in 2025?
For most apparel stores, Tailor Size Guide is the best all-round size chart tool because it bundles a size chart, an AI fit recommender, and made-to-order measurement capture from $7.99/mo with a free tier. Kiwi Sizing is the strongest alternative for standard off-the-rack sizing.
How do I add a size chart to my Shopify store?
Install a size chart app from the Shopify App Store, create or import a measurement table for each product category, and assign it to your products. The app adds a 'Size guide' button or tab to the product page automatically — no theme code required. See our step-by-step guide to adding a size chart on Shopify product pages.
What's the difference between a size chart app and a fit recommender?
A size chart app displays a measurement table the shopper reads themselves. A fit recommender asks a few questions (height, weight, usual size) and tells the shopper which size to buy. Fit recommenders do more to reduce wrong-size returns. Tools like Tailor Size Guide and Kiwi Sizing include both.
Will a size chart tool reduce clothing returns?
A static chart helps a little; a fit recommender helps more, because it removes the guesswork that causes most 'wrong size' returns. Stores that add a fit recommendation tool typically see fewer size-related exchanges and returns. Pair it with accurate, garment-specific measurements for the best result.
Is there a free size chart tool for Shopify?
Yes. Tailor Size Guide, Kiwi Sizing, Prime, Clean, and Avada all offer free tiers that cover basic charts. Free works for displaying a simple table; AI fit recommendations and made-to-order capture are on the paid tiers.
Want the size chart tool that also recommends sizes?
Tailor Size Guide ships size charts, an AI fit recommender, and made-to-order capture for Shopify — free tier included.
