Size charts are often treated as an afterthought, hidden away in footer links. However, size charts are critical checkout pages. Optimizing them reduces size doubts and increases add-to-cart rates.
1. Mobile-First Sizing UX
Never upload a static image of a size grid. Shoppers on mobile screens must pinch-and-zoom to read them, leading to frustration and cart abandonment. Use clean, responsive HTML tables that adapt to mobile viewports.
2. Product-Specific Dimensions
A generic brand size chart is a major contributor to sizing returns. If your shirts fit oversized but your knits fit snug, they cannot share a sizing chart. Create specific specs for every garment category.
