About SizeFit: Size Chart Fit Finder

Wrong sizes are a common return in apparel, footwear, and accessories. SizeFit adds clear size charts and a guided fit finder to your product pages so shoppers can choose their size with confidence, even when they fall between two, and you see fewer returns. Set up in minutes from a template, a spreadsheet paste, or a CSV file, then assign across your whole store or by collection, product, or tag. See an honest returns avoided estimate and export your charts anytime.
