Fitt: Size Chart & Size Guide

Fitt adds a size guide directly on your product pages, matching your theme's fonts and colors. The app helps shoppers find the right size so you get fewer returns due to sizing issues. The size guide includes size charts, measuring instructions, and a "Find my size" feature that suggests the best fit based on customer measurements and automatically selects it. You can start with ready-made templates or import size charts from spreadsheets, PDFs, web pages, or other size chart apps. Rules let you assign the right chart to each product automatically, while the Coverage feature shows which products still need a size guide. Fitt runs a daily check to make sure your size guide is displaying correctly and sends you an email alert if something goes wrong. All your charts are stored securely in your store.
