Free Size Chart Generator for Shopify
Build a clean, professional size chart for your clothing store in under a minute. Pick a template, choose a theme, edit the measurements, then copy and paste the code into Shopify. No coding needed.
Why do you need a size chart?
Size uncertainty is the number one reason for returns in fashion e-commerce. A clear, easy-to-read size chart helps customers pick the right fit with confidence, which means fewer returns and more completed checkouts. If your product pages have no chart, or a chart that is hard to read on a phone, shoppers guess. And guessing is where returns come from.
Responsive design
Your chart looks clean on mobile, tablet, and desktop, where most of your shoppers actually are.
Four themes
Pick a look that matches your store's branding, from soft ivory to bold noir.
No coding required
The generator writes the HTML and CSS for you. Copy, paste, done.
Two unit systems
Switch between inches and centimetres with one click. Values convert automatically.

Go beyond size charts
A size chart helps shoppers pick a size. It cannot show how the piece looks on them. Reality Try's AI virtual try-on does, on the shopper's own photo, right on your product page.
