Belt Size Calculator & Chart

Buckle turns one waist measurement into the belt size you actually need to order — in EU, US, UK and Japanese sizing, side by side, with a picture of which hole you will end up on. Most belt mistakes happen at the last step: you know your waist, but the shop lists sizes in centimeters, letters or UK inches, and every brand chart looks different. Buckle removes the guesswork. Type your waist in cm or inches, and the nearest belt size for every region appears instantly, together with a hole-fit strip that shows whether that belt will sit snug, loose or right in the middle. WHAT YOU GET • Order the right belt on the first try, whether the shop lists EU, US, UK or JP sizes • See at a glance whether a belt will sit snug, loose or in the sweet spot before you buy • Switch between cm and inches with one tap — no mental math, no conversion tables • Keep a saved size for every person you buy for, so gifts and reorders fit • Browse the full size reference from 70 cm to 130 cm whenever you need a second look • Get an answer in seconds, offline, with nothing to sign up for PERFECT FOR • Shoppers ordering belts online from brands in another country • Anyone buying a belt as a gift and unsure which size to pick • Families who want one place that remembers everybody's size • Travelers browsing shops where the size labels look unfamiliar WHY NOT JUST SEARCH FOR A CHART? Web charts disagree with each other, rarely cover all four regions, and never tell you how the holes line up. Buckle uses one consistent reference, converts your exact measurement rather than a rounded guess, and keeps the result saved for the next time you shop. General unit converters can turn centimeters into inches, but they cannot tell you that 90 cm means a medium in the US and a 36 in the UK.
