How to Measure at Home
String or Paper Method
Wrap a thin strip of paper or string around your finger at the knuckle. Mark where it overlaps, then measure the length with a ruler in millimetres.
Existing Ring
Place an existing ring on a ruler and measure the inner diameter in millimetres. Multiply by π (3.14159) to get the inner circumference in mm.
Find Your Size
Match your measurement (mm) to the table above. If between two sizes, we recommend the larger size for comfort.

How to Measure Your Wrist
Wrap & Mark
Wrap a soft tape measure or a strip of paper snugly around the narrowest part of your wrist — usually just above the wrist bone.
Read the Measurement
Note where the paper or tape overlaps. Measure the length in centimetres. This is your wrist circumference.
Add Comfort
Add 1 cm for a snug tennis fit, or 2 cm for a comfortable everyday fit. Match the total to the chart above.
