Increase sales with fit recommender and stylish size charts

Boost sales and reduce returns with size charts & size guides.

Stunning size charts to increase sales and reduce returns.


Fast, beautiful size charts with a rule-based size recommender. Fewer returns, more conversions.
Sizing doubt is the #1 reason fashion shoppers hesitate, and wrong sizes drive costly returns. FitKit fixes both without slowing your store: the size guide link renders with zero network calls and the modal is under 5 KB, loaded only when a shopper clicks. Start from ready-made templates (tops, pants, shoes, rings, kids), edit rows and columns freely, and let shoppers switch cm/inches automatically. Assign guides by product, tag, collection, vendor or store-wide. No AI and no customer data.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows FitKit ‑ Size Charts & Guide on a store, it is there.
