How to Measure Your Ring Size
Measure your ring size at home with a paper strip, or by measuring a ring that already fits.
String Method
Wrap a thin strip of paper or string around the base of the finger. Mark where the ends meet and measure the length in millimeters. Compare to the chart above.
Existing Ring Method
Measure the inner diameter of a ring that fits well. Compare the measurement in millimeters to the chart above.
Sizing Tips
- Measure at the end of the day when fingers are at their largest.
- If between sizes, choose the larger size.
- Wide bands require a slightly larger size than thin bands.
Printable Ring Sizer
Print this sizer at 100% scale, then lay a ring over the circles or wrap the paper strip around your finger to read your size.
Print at 100% scale — turn off 'fit to page' — or the measurement will be wrong.
