The 10 Best Size Guide Apps for Shopify
The top 10 apps merchants see when they search the Shopify App Store for size guide, 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.

What to look for in a Size Guide app
- How a chart finds its products
- Assigning by collection, tag, product type or vendor is the difference between a fifteen-minute setup and an afternoon that has to be repeated every time the range changes. Ask what happens to a product added next month: does it inherit a chart, or does it quietly have none?
- One source for both unit systems
- A guide that stores inches and centimetres as two separate tables will eventually contradict itself, and nobody notices until a customer does. Conversion from a single set of numbers is the feature; two tables side by side is the problem wearing a costume.
- A chart and a recommender are different purchases
- Showing a table is content management. Telling somebody they are probably a medium is a prediction, built from returns data or body measurements, and it succeeds or fails on completely different grounds. Several listings sell both; be clear which one you are actually buying.

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.
