FitMatch – Find Your Right Clothing Size

Get an AI size recommendation on any webshop, based on your own measurements. Fewer returns, less guessing.

Stop guessing your size. FitMatch reads the product page you're already on, compares the garment against your own body measurements, and tells you which size to pick — with an honest confidence score so you know how much to trust it. HOW IT WORKS FitMatch uses the most reliable source available, in this order: 1. The store's own size chart. If the page lists real measurements, they're matched exactly against your body. Highest confidence. 2. AI estimate. Many shops publish no measurements at all. FitMatch then reads the product photos and the model reference ("model is 181 cm and wears M") and works out how the garment will actually sit on you. Estimated numbers are clearly marked as estimates — never presented as fact. 3. Generic chart. If nothing readable exists, it falls back to a standard chart and tells you plainly that it's only a rough guide. WHAT MAKES IT DIFFERENT • Anchored to the model — it reasons from the model's height and size and how the garment drapes in the photos, instead of inventing numbers. • Fit shown per body zone — see how it sits on chest, shoulders, waist and hips. • You vs the model — compare your measurements directly against the model's. • Honest about uncertainty — every result carries a confidence score. • Consistent — the same garment always gives the same answer. • Fit preference — tell it whether you like things tighter or roomier, and it only changes size when your measurements actually allow it. YOUR PRIVACY Your measurements are stored locally in your browser. There are no accounts, no sign-up, no advertising, and nothing is sold. FitMatch only reads a page when you click the button — it never runs in the background. Available in English, Danish, German, French and Spanish. Affiliate disclosure: FitMatch may earn a commission if you choose to click a link to a retailer from the extension. This never affects the size recommended.
