How our fit scoring works

Enter your measurements once in the size calculator on any product page, or save them to your fit profile so every product shows your size. We compare your numbers to the brand's official size chart for that category, not a generic one. Bust, chest, waist, hip, inseam, and arm length each map to the chart rows the manufacturer published.

Charts describe the ideal; riders describe reality. We track each brand's sizing tendency on a five point scale, from runs small to runs large, built from the fit reports across that brand's gear. If a brand consistently runs small, the calculator nudges your recommendation up rather than handing you a size that will not zip.

When a product has at least three rider fit reports, we show the distribution: the share of riders who said it runs small, true to size, or large, and how many kept it. That percentage is the evidence behind the fit verdict at the top of each product page. More reports mean a more confident read, and we tell you the count so you can weigh it yourself.

Beyond up or down, we group rider feedback by body area: toe box, calf, and heel for boots; shoulders, chest, sleeves, and torso for jackets; rise, hips, thighs, and inseam for trousers. A piece that runs true to size overall can still pinch a wide calf or gap at the waist, and those area-level notes are where a fit succeeds or fails.

A recommendation is a strong starting point, not a guarantee. Coverage depends on how many riders reviewed a product, and bodies and preferences vary. Always confirm size, stock, and the return policy with the retailer before you buy. The sources behind every score are listed on our data sources page.
