This is a demo store, so nothing is added or sold.
Everything a size chart should do
A size chart link appears where shoppers are already choosing, with an optional fit note next to it.
Shoppers enter their measurements and get a suggestion calculated from your own chart.
One switch converts every measurement. You enter each chart once.
Show a chart on chosen products, categories, SKU prefixes or your whole store.
Start from tops, trousers, shirts, bras, gloves, shoes and more, then adjust to your own measurements.
Copy rows from a spreadsheet, or import and export CSV files.
The chart window follows your site language in 30 languages. Your chart content stays exactly as you wrote it.
Ask the Wix AI assistant to list your charts or explain where one is set to show, right from your dashboard. Read-only, so it never changes your charts.

Fitly adds a plugin to the Wix Stores product page. You place it once and it shows on the products that have a chart.
Each product shows one chart. For sets with separate sizing, like the lingerie above, sell the pieces as separate products and give each its own chart. Combining two charts under one product isn't available.
No. The window's buttons and labels follow your site language, while chart titles, column names and notes stay as you wrote them.
One chart is shown. A chart set on the product wins over a category or SKU rule, which wins over “all products”. You can set a priority within the same level.
