Measure your wrist size
Step 1: Wrap the tape measure around the wrist bone, so that it fits snugly without feeling too tight or too loose.
Step 2: Mark where the tape measure overlaps. This is the exact circumference of your wrist.
Note: You can substitute the measuring tape with a string or ribbon and use a straight ruler to measure the length from the point of overlap to the end.
