Add a size chart to your Shopify store
Shopify doesn't come with a size chart, but adding one takes minutes. Here's how to show the right size chart on every product, in the right place, in your customers' language.
A size chart answers the question every clothing and shoe customer has before they buy: which size should I pick? When the answer is right there on the product page, customers buy with more confidence and fewer orders come back because of the wrong size.
Shopify has no built-in size chart feature, so you have two options: build one with your theme's pop-up block, or use a size chart app. This page compares both, then walks you through everything a great Shopify size chart needs.
Two ways to add a size chart to Shopify
Your theme's pop-up block is free and fine for one chart across the whole store. A size chart app is the better choice once different products need different charts.
| Theme pop-up block (free) | Size chart app (Jotly) | |
|---|---|---|
| Different charts on different products | Manual setup on every product | Assign by product, collection, tag, vendor or metafield |
| Proper size table | Typed into a page by hand | A responsive table built for size charts |
| cm / inch switch | No | Yes, plus mm, m and feet |
| How-to-measure drawings | Upload your own images | Labelled drawings in every template |
| Templates | None | 123 free templates |
| Button placement | Wherever your theme's block can go | Next to the size label, by Add to cart, floating or anywhere |
| Translations | Translate the page by hand | Store languages and AI translation |
| Price | Free | Free plan, paid plans from $6.99 a month |

What a great Shopify size chart includes
A clear size table
Sizes down the side, measurements across the top, and a note saying whether they're body or garment measurements.
Both cm and inches
A unit switch lets every customer read the chart in the units they know.
How to measure
A labelled drawing and short steps, so customers measure the same way you did.
Fit notes
"Runs small, size up" or "relaxed fit" is often the most useful line on the chart.
The right chart for the product
Dresses, jeans and kids' clothing each need their own chart, not one chart for everything.
Easy to find
A size chart button next to the size options or just above Add to cart.

Shopify size chart questions
Does Shopify have a built-in size chart?
No. Shopify doesn't have a size chart feature. You can show one with your theme's pop-up block and a Shopify page, or with a size chart app like Jotly.
How do I add a size chart to Shopify?
Install a size chart app like Jotly, create a chart from a template, choose which products show it and turn on the app embed in your theme. Without an app, create a Shopify page with your chart and add your theme's pop-up block to the product page.
Is there a free size chart app for Shopify?
Yes. Jotly has a free plan with up to 2 size guides, all 123 templates, cm/inch conversion and flexible button placement. Paid plans start at $6.99 a month with a 7-day free trial.
Can I show different size charts on different products?
Yes. With Jotly you assign each size chart to specific products, collections, tags, vendors or a product metafield, and new products pick up the right chart automatically.
Where should the size chart go on a product page?
Next to the size options or just above the Add to cart button, where customers choose their size.
Does a size chart app work with my Shopify theme?
Jotly works with any Shopify theme. On Online Store 2.0 themes you can place the size chart button anywhere on the page with the Jotly app block; on older themes, choose next to the size label, above or below Add to cart, or a floating button.
What's the difference between a size chart and a size guide?
A size chart is the table of sizes and measurements. A size guide is the wider help around it, like how to measure and fit advice. Most stores use the two names for the same thing.
Can I translate my size chart?
Yes. Jotly translates size charts into your store's languages and, with AI, into any language, including the chart name and the button text (Global plan and above).
Free plan, no card needed. Paid plans include a 7-day free trial.
