Everything a size chart app should do
Size charts, a size finder, the rules that put them on the right products, a guide that looks like your store, in your shoppers’ languages, with the numbers to check it works. Each with a page of its own.

Paste from a spreadsheet or start from 39 templates. Units, size systems, how to measure guides, tabs and images.
