Find your size in 60 seconds
Your size, from your phone.
Calibrate the screen with any bank card, then drop a ring you own on it, or use a strip of paper. No ring? We'll predict it. Wrong size? Swapping is quick and easy.
Step 1 · Calibrate. Hold a £1 coin on the screen and drag the handle until the circle matches it.
Not calibrated23.43 mm
Step 2 · Place a ring that fits the right finger on the screen. Drag the handle until the circle sits exactly on the ring's inside edge.
— mm
- Cut a strip of paper about 5 mm wide.
- Wrap it round the base of the finger — over the knuckle if the knuckle is bigger.
- Mark where it overlaps, then lay it on the ruler below with the end at 0.
No ring, no paper? We'll estimate from a few things about you. Expect ±1 size, and swaps are quick and easy.

Evidence
Why a ring that gives way is the safer ring.
Ring avulsion is rare but serious. A silicone band is designed to stretch and tear away under a hard pull, which reduces the risk of ring injuries compared with metal.

Questions
Quick answers.
What size am I?
Use the size guide above: measure a ring you already wear, or wrap a strip of paper round your finger. Silicone fits snug, so if you're between sizes go down. Get it wrong and swapping is quick and easy.
How fast is delivery?
Orders placed before 3pm Monday to Friday ship the same day from our UK warehouse by Royal Mail Tracked 48, normally 2–3 working days. You get a tracking link by email.
Can I wear it in the gym, at work, in water?
Yes. It's non-conductive, heat-safe to normal kitchen and workshop temperatures, waterproof and chlorine-proof, and it is designed to tear away under a hard pull.
Is it safe for people with a nickel allergy?
Yes. Medical-grade silicone contains no metal, so it's hypoallergenic.
What's your returns policy?
30-day returns on unworn rings. Quick, easy size swaps. Start it from the Returns page and you get the Royal Mail label by email.
