About Quicksize
Last updated: 26 October 2026
The site
Quicksize helps you find your size when buying clothes or shoes, at home or abroad: conversion guides between sizing systems (FR, EU, US, UK, IT…), calculators based on your measurements, and the official charts of 68 brands. The site is available in 7 languages.
Our method
Brand charts: taken from each brand's official website and reproduced in centimetres, with a link to the source and the date they were recorded. When a source contains an inconsistency, we point it out rather than quietly correcting it.
General guides: conversions between sizing systems and measuring tips, based on standards and on the charts of major retailers.
Independence
Quicksize is not affiliated with any brand and earns no commission on sales. The site is funded solely by advertising (Google AdSense).
