How do I measure my ring size?
A question we commonly get asked is 'how do I measure my ring size'?
Womens ring sizes are commonly between a size 4 and 7 whereas mens sizes are normally between 7-11, please note, just like shoe sizes this can vary from brand to brand and peoples finger sizes can vary outside of these averages.

To measure your finger you can take a regular tape measure, preferably a tailors tape measure for ease of use and use our mm or cm ring size conversion chart below.
