The top 10 apps merchants see when they search the Shopify App Store for size charts, in the exact order the store ranks them. Only Shopify's organic ranking is shown, never sponsored ads.
Updated September 8, 2026 · Organic rankingShopify knows what size something is and nothing whatsoever about what that means. Its product taxonomy has a size attribute, and every value in it is a label: extra large, nought to three months, a shoe number. There is no measurement anywhere in the model, no chest in centimetres, no inside leg, and no standard field for a chart. A size guide is therefore content you have to model yourself.
The pieces to do that with do exist. A metaobject can hold a repeatable structured chart, a reference field can attach one to a product, and a rich text or file field can carry a table or an image. What is missing is the assembly, plus the two things that make it survivable at any scale: getting the right chart onto the right products by rule rather than one at a time, and offering both unit systems without maintaining two copies that slowly disagree.

Built for Shopify
Built for Shopify is the highest level of recognition Shopify awards an app. To earn
the badge, an app must meet Shopify's standards for safety, performance, ease of use,
and proven usefulness: it cannot slow down the admin, storefront, or checkout, must
integrate seamlessly into the Shopify admin, and must demonstrate quality through
installs, reviews, and ratings over time. When comparing similar apps, preferring
ones with the badge is a safe default.
