How to Measure
String Method
Wrap a piece of string or thin strip of paper snugly around the base of your finger. Mark where the end meets. Lay it flat and measure the length in millimeters — then compare to the inner diameter column above.
Existing Ring
Take a ring that already fits the intended finger well. Measure the inner diameter in millimeters using a ruler and match it to the chart above.
Paper Strip
Download and print our sizing strip at 100% scale, then follow the instructions to wrap it around your finger. Download sizing strip (PDF)
Tips for the Best Fit
Measure at the end of the day when your fingers are warmest and at their largest.
If you fall between two sizes, go up — a slightly loose ring is more comfortable than a tight one.
KEORA comes in full sizes only (no half sizes). We include a free sizing kit with every order.
