Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.
A US 34in belt converts to a EU 86 on the standard chart, the same waist-in-inches-to-centimetres math used across this site's clothing conversions, since a belt is sized to the waist it's meant to sit at rather than to garment cut.
Belt sizing is usually measured to the actual hole the buckle sits on rather than the belt's total length, so if you're converting from a belt you already own, measure to the hole you currently use, not the strap's full length.
Frequently asked questions
Should I measure my waist or my current belt to convert belt size?
Measure to the hole you actually use on a belt that fits well, not the full strap length — belt size numbers refer to the fastened waist measurement, and the strap is cut several inches longer than that.
