Size charts and assignment rules
Load your measurements as size charts and tell the app which products each chart covers - by product, vendor, type, tag or collection.

A size chart is the measurements behind every recommendation. Each chart is a set of sizes, small to large, with the body measurements that fit each one. You can hold several charts - tops and bottoms, or one per brand.
Assigning a chart to products
Each chart carries a rule for which products it covers, so the right chart is used automatically:
- All products, or
- By product, vendor, product type, tag, or collection.
When more than one chart could apply, the higher-priority chart wins, and a chart scoped to a brand only applies to that brand. If nothing matches precisely, the app falls back to a sensible chart for the shopper's gender rather than recommending off the wrong one.
Corrections
If a brand or a specific product runs small or large against its own chart, set a correction - a nudge of a size up or down. The recommendation applies it and tells the shopper why. Over time, buyers' fit feedback does this automatically; a correction is the manual version for when you already know.
