About ScaleChart: Size Chart & Guide

When customers pick the wrong size, you lose sales and face costly returns. ScaleChart is a size chart builder that creates custom AI charts and fit advice to reduce returns. Auto-generate a chart from a photo or text, then auto-assign or bulk-apply it across products. Show it in a mobile-friendly popup, tabs, or theme-native dropdown. Add image and color swatches, a sticky add-to-cart bar, cart upsells, and one-click post-purchase offers. Replaces 5-6 apps with unit conversion and translations.
