Step 1

Wrap a piece of string around the largest part of your finger (this may be the knuckle).

Mark or cut the string at the length which wraps around your finger exactly one time.

Step 3

Measure that length of string against a standard ruler.

Step 4

Compare against the closest circumference in the chart below to find your size.
