Ring Sizing Chart
If you are unable to have your ring size measured at a jewellers, please use the guides below.
We can make both UK and US ring sizes.
MEASURE AN EXISTING RING
- Find your favourite ring that fits the desired finger.
- Use a ruler to measure the internal diameter of the ring (in mm).
- Use the below chart diameter to determine your ring size.
- If you are in-between sizes, we recommend choosing the larger size.
MEASURE YOUR FINGER
- Cut a thin strip of paper and wrap it around your finger where you would like the ring to sit.
- Make sure that the paper is pulled snug to your finger, the tighter the better, to find your best fit.
- Mark the spot where the paper meets and measure the distance with a ruler (mm).
- Use the below chart circumference to determine your ring size.
- If you are in-between sizes, we recommend choosing the larger size.

Helpful Tips
• The average ring size for women is US7 / UK N 1/2
• When measuring your ring size, be sure to measure the exact finger where the ring is to be worn.
• Measure your ring size at the end of the day when fingers are at their largest.
• Do not measure your fingers when they are cold as they may have shrunk up to half a size.
• Do not measure your fingers after alcohol and salt intake as these can make your fingers swell.
