How to Find Your Ring Size at Home (UK Guide)

Every ring we make is made to order in your size — which means getting the size right matters. UK sizes run in letters (roughly F to Z), and the difference between one letter and the next is under half a millimetre, so "about right" isn't quite good enough. Here are the reliable routes, best first — all of them from your own kitchen table.

Option 1 — Use a ring sizer (most accurate)

A set of plastic ring sizing gauges — a keyring of graded rings, the same idea as the steel set a jeweller uses — costs two or three pounds online and usually arrives the next day. You try the sizes on the actual finger and read the size straight off, which is the only method at home that properly accounts for a wide knuckle. Trying real rings on is also more reliable than the single strap-style sizer, where the tension is guesswork. On a piece you'll wear for decades, it's the cheapest certainty you'll ever buy — order one before you order the ring, and tell us the size you land on.

Option 2 — Measure a ring that already fits (best for a surprise)

Take a ring the wearer already uses on the same finger of the same hand (sizes differ between hands), and measure its inside diameter in millimetres with a ruler — measure straight across the widest part of the inside circle, edge to edge. A digital caliper is far more accurate if you can borrow one. Tell us that measurement in your order notes or by email and we'll convert it to the correct UK letter for you, or check it yourself against our ring size guide. A millimetre matters here, so measure twice.

Option 3 — The string method (use with care)

Wrap a strip of paper or non-stretch string snugly around the base of the finger, mark where it overlaps, and measure the length in millimetres — that's the circumference. It's the least accurate method because tension is hard to judge: do it three times, at the end of the day (fingers swell slightly), and use the average. Again, send us the number and we'll do the conversion.

Sizing a surprise proposal ring

Three quiet tactics, in order of reliability:

• Borrow a ring they wear on the ring finger (or any finger — tell us which) and measure the inside diameter, or trace its inner circle on paper twice.
• Recruit an accomplice — a friend or family member can often engineer a casual ring try-on and report back.
• When in doubt, size up slightly. A ring that's a little large can be worn on the day and resized after; one that doesn't go on can't. Most of our rings resize within a sensible range — eternity and full pavé bands are the exception, so ask us first if that's the style.

Two things worth knowing

• Fingers change size through the day and with temperature — measure when hands are warm and relaxed, not straight after a cold walk or a workout.
• Wide bands fit tighter than slim ones — if you're choosing a chunky style, mention it and we'll advise.

Once you have your size — or even just a measurement you're half-sure of — leave it in the order notes at checkout or email us before ordering and we'll confirm everything in writing before production starts. We'd genuinely rather spend ten minutes getting it right with you than have you guess. Then the only decision left is the ring itself: start with the engagement collection or everyday diamond rings.
