Frequently Asked Questions
How much can size charts reduce returns?
Comprehensive size guides typically reduce size-related returns by 25-35%. Combined with fit recommendations, some stores see even greater reductions. The key is providing clear, accurate information with measurement guidance.
Should I use popup or inline size charts?
Popups keep product pages clean and work well when size charts are detailed. Inline display works better for simple charts customers should see immediately. Test both approaches, some audiences prefer one over the other.
How do I handle multiple sizing systems (US, UK, EU)?
Display all relevant sizing systems in a conversion table format. Many plugins support multi-column tables showing US, UK, and EU sizes side by side. Include measurement-based sizing for customers who don’t know their size in any system.
What measurements should I include?
For apparel: chest/bust, waist, hips, length, sleeve length. For footwear: length and width. Include both body measurements and garment measurements where relevant. Specify whether measurements are body or garment-based.
Do AI fit recommendations actually work?
Yes, AI-powered fit finders like Kiwi Sizing show measurable improvements in size accuracy. They work by learning from customer feedback and purchase/return patterns. Effectiveness improves over time as more data is collected.
How do I handle brands with different sizing?
Use plugins supporting multi-brand or attribute-based charts. Create separate size charts for each brand and assign them based on product brand attribute. Include “runs small/large” notes for brands with known fit variations.
