What Size?

Find your fit faster

Free · Designed for iPad. Not verified for macOS.

Know your likely clothing size before you buy. Compare your measurements across UK stores with private, on-device fit guidance. What Size? helps you feel more confident choosing clothes online. Enter your measurements once, choose a clothing category, and compare likely size guidance across UK retailers. The app is designed for women shopping for clothes who want a calmer, clearer way to understand fit before buying. What Size? can help with: Dresses, tops, jeans, trousers and coats Bust, waist, hips, height and inside-leg measurements Store-by-store size comparison Fit preferences for snug, true-to-size or relaxed fits Personal fit notes and saved shopping items Guided measurement help Clear caveats where retailer data is limited Your measurements stay on your device. There is no account, no login, no camera, and no personal measurement data is sent to a server. Some retailer size information may be incomplete, product-specific, or not suitable for a confident recommendation. Where that happens, What Size? shows guidance with a clear caveat rather than pretending the data is stronger than it is. What Size? is a fit guidance tool, not a guarantee. Always check the retailer’s own size guide and returns policy before buying.
