Ring size guide
Ring size chart: how to measure your ring size
You can't try a ring on through a screen, so we made sizing simple. Pick the method you can do right now.
N°01 Measure a ring you already wear
- Take a ring that fits the finger you'll wear this one on.
- Measure the inside diameter in millimetres with a ruler.
- Match it in the chart. Between sizes? Go up, silicone stretches slightly.
N°02 String and ruler
- Wrap a thin strip of paper or string around the base of your finger, over the knuckle if it's larger.
- Mark where it overlaps and measure the length in mm.
- Divide by 3.14 for the diameter, then match it in the chart.
N°03 Your existing ring size
If you know your UK/SA letter size, find it in the middle column. If you only know a US number, that's the first column.

Ring size questions.
How do I measure my ring size at home?
Take a ring that fits the right finger and measure its inside diameter in millimetres, then match it in the chart. No ring? Wrap a strip of paper around the base of your finger, mark where it overlaps, measure that length in mm and match it to the circumference column.
What is a size 7 ring in South Africa?

How do I convert my letter ring size to a number?

Should a silicone ring fit tighter than a metal ring?
Yes, slightly. Silicone stretches a little and should sit snug so it doesn’t spin or slip off in the water. If you are between two sizes, go down.
What are the most common ring sizes?
Most men wear a US 9 to 11 and most women a US 6 to 7. Your finger is bigger when it’s warm and in the afternoon, so measure then.
What if my ring doesn’t fit?
Exchange it for another size within 30 days of delivery. Start the exchange online and the courier collects the old ring from your door; you pay the courier collection.
