How to Track Size Chart Analytics on Shopify
Built-in dashboard + GA4 + Meta Pixel events. Measure what matters.
The 4 Key Metrics
1. Open rate. % of product page visits that open the size chart. Industry average: 15-25%. Higher is good.
2. Recommender usage. % who use the size finder. Industry: 8-15%. Indicates trust + adoption.
3. Conversion lift. Purchase rate for chart-openers vs non-openers. Typical: 1.5-2x lift.
4. Return rate by size. Identifies sizing issues (e.g., size M returning 2x more than other sizes signals it runs off-fit).
