Simplify sizing with customizable charts, minimal impact on store speed.
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.
