What is the average wrist size and how do I measure my wrist?
Measuring Your Wrist Size
You can get a measurement of your wrist by using a soft measuring tape or by measuring the inside of your your best fitting watch. If you don't have a soft measuring tape, you can wrap a ribbon or a piece of string around your wrist at the wrist bone, mark the spot where it meets, and then measure it with a ruler to determine your wrist size. To get the best fit, measure snug at the wrist bone.
When buying a bracelet, your bracelet size is your wrist size plus 1 inch.
When buying a watch band, you need to take into account the size of the watch. A 7 inch watch band may seem too small, but the watch itself adds another inch or so, depending on the watch. A standard size watch strap is good for wrists between 7 and 8 inches.
The average wrist size for adults is 7.17 inches and is correlated with height. Taller people tend to have larger wrists.
