Your ring should fit comfortably
It should be able to fit over your knuckle when you take it off. The thicker the ring, the tighter the fit, so if you choose a ring with a deep band, you will likely need to go one size up.
Your fingers will change size slightly through the day by physical activity and temperature. The best time of day to measure is in the evening when your fingers are the largest. Avoid measuring when you’re cold, as fingers are at least half a size smaller.
Most of our rings in the website are in sizes K (small), M (medium), O (large). However we can make any size that you may require as made-to-order. Please contact us via firstname.lastname@example.org if you are London-based, as we offer a measuring service in our East London studio.
All of our handmade rings are sized using UK sizes.
