How to Measure Your Ring Size
Find your size in 3 easy steps
- Wrap a thin strip of paper or string around the base of your finger.
- Mark where the ends meet, then lay it flat and measure that length in millimetres.
- Match your measurement to the “Circumference” column above to find your ring size.
Tips for Accurate Measurement
- Measure at the end of the day when your fingers are warm and at their largest.
- Take two or three measurements to confirm consistency.
- If your knuckle is much larger than the base of your finger, measure both and choose the larger size.
- Wider bands fit more snugly. Consider sizing up if you’re choosing a thick ring.
