Help shoppers choose their size with clear size charts and a fit finder on your product pages
Buying clothes and shoes online means guessing the size. SizeChartKit adds a clear size guide next to your size picker.
Start from a ready-made template and adjust it to your fit. Assign each chart to collections, tags, product types, vendors or single products, with a default for everything else. Shoppers switch between inches and centimeters in one tap, and the fit finder recommends a size from their own measurements, directly in their browser.
