Fitline‑ AI Product Size Guide

Fitline adds a size guide to your product pages so shoppers pick the right size the first time. Start from a template for apparel, footwear, rings, kids, or intimates, or build a custom chart for any product type. Edit any cell, add sizes and measurements, and switch between cm and inches with automatic conversion. Show the guide on all products or specific ones, as a popup, inline block, or floating tab. Turn on AI size recommendations: shoppers enter measurements and get a suggested size.
