How to measure your wrist?

1) Take a rope and wrap it around your wrist until the two ends touch without sagging.

You can use a tape measure, shoelace, rope, fabric, or cable—anything that can be wrapped around your wrist will work.

The size of the wrist should be free from slack and not so tight that it stops blood circulation.

2) Mark the exact length on the rope and use a ruler to determine your true size.
