HOW TO MEASURE YOUR WRIST
Use a measuring tape to measure your wrist size
Take the measuring tape and fold it around your wrist (like on the photo)
Make sure you hold the measuring tape tight
Specify the exact number of centimeters or inches
(the measurings on the photo are 18.5 cm)
When you dont have a measuring tape, DON'T WORRY!
Follow the steps below...
Use a piece of string or rope to hold around your wrist (like on the photo)
Use a pen or marker to mark the point where the string or rope meet again
Measure the piece of rope using a ruler or whatever you can find that does the job
