What size chart metrics should I track?

Open rate (% of product page visits that open the size chart), recommender usage (% who use the size finder), conversion lift (purchases for chart-openers vs non-openers), and return rate by size (which size returns most).

Does Tailor Size Guide push events to GA4 and Meta Pixel?

Yes — automatically. Events: tsg_chart_opened, tsg_recommender_used, tsg_size_recommended, tsg_unit_switched. View in GA4 Realtime → Events. Build conversion funnels by enabling them as conversions.

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).
