FitMorph AI Sizing

Size recommendations on independent apparel stores, matched to your own measurements.

Stop guessing your size. FitMorph shows a size recommendation right above the "Add to cart" button on independent clothing stores, matched to your own body measurements. HOW IT WORKS 1. Enter measurements once for each person you shop for: yourself, a partner, your kids (chest, shoulders, waist, hips, and optionally height, sleeve, neck, inseam and underbust; only what you know). Not sure how to measure? A built-in guide shows exactly where, or estimate from the size you usually wear or from a t-shirt that fits you well. 2. Open a product page on a supported store. 3. FitMorph reads the store's size chart and shows the size that fits you, with a match score and a region-by-region fit guide: snug across the shoulders, perfect at the waist, and so on. GETS SMARTER WITH YOU After your order arrives, tell FitMorph whether it fitted: Too small, Just right or Too big. Answers are de-identified (never your measurements, your name or what you bought) and help improve recommendations for everyone. FOR THE WHOLE FAMILY • Men's, women's, teen and kids' sizes. Switch who you're shopping for right in the size box. • Tees, shirts, hoodies, pants and jeans (waist x inseam, like 32x32), underwear, and bras (band and cup, like 34C). • Tall and big sizes (MT, LT, 1X-4X), kids' sizes by age and height, and dress-shirt neck sizes. • On pages with several charts (men's and women's, adult and youth), FitMorph uses the right one. SMARTER THAN A SIZE CHART • Fabric-aware: stretch fabrics, rigid denim and knits each get the right amount of room. • Respects the designer's intent: oversized and slim fits are sized the way they were meant to be worn. • Reads size charts even when the store only posts them as a picture. • Flags half measurements and tells you when no size fits well, instead of guessing. PRIVATE BY DESIGN • Your measurements are encrypted on your device (AES-256-GCM). • No account, no photos, no ads, no tracking. • Measurements are used only to calculate a size and are never stored on our servers. • "Delete my data" erases everything with one click. WHERE IT WORKS Product pages on Shopify, WooCommerce and Big Cartel stores, and other stores that publish standard product data, whether the size chart is a table, text or a picture. FitMorph is new.
