About Sizuro
Sizuro is an independent size-conversion site. We built it because ring, bra and shoe sizes are labelled differently almost everywhere you shop, and the charts that exist are either buried inside a retailer's page or don't explain how the number was worked out.
Every converter on this site runs entirely in your browser — nothing you type is uploaded or stored anywhere, by us or by anyone else. We use standard, published sizing methods (cited on each tool page) rather than a single brand's chart, because sizing genuinely varies between brands and no converter can promise an exact fit for every one of them.
The site is supported by ads and, where relevant, affiliate links — clearly marked wherever they appear.
