AI size finder for fashion brands
Fewer returns.
Perfect fit from one photo.
Sizing is the top reason clothes get sent back. FitSnap finds each shopper's size from a single photo, matched to your own size guides, including petite, tall and plus.
Photos are processed on the shopper's device and never uploaded.

For shoppers
Brands using FitSnap
Find your size at any of them from one photo.
How it works
Thirty seconds from photo to size.
01
Enter height
Height sets real-world scale and picks petite, regular or tall. Weight and fit preference are optional.
02
Snap one photo
On-device AI maps 33 body landmarks and a full silhouette in under a second. Nothing is uploaded.
03
Get the size
Matched to your own size guide, across every range you sell, with fit notes for chest, waist and hips.
Size guides
One guide. Every product.
Set your sizes and measurements once per fit, not once per SKU. Sell the same tee in new colours every season and the guide just keeps working. Add ranges like Petite, Tall or Plus and FitSnap picks the right one from the shopper's height and shape.
Tops & tees
Shared by every tee and top
Install
Live in one line.
Paste the snippet once in your site template. On every product page FitSnap picks the size guide, places itself by the add-to-cart button and selects the size for the shopper. Shopify stores connect with one click.
