Sizing Apple Watch

What size do I need?

The heart rate sensor is located on the back of the Apple Watch. If you take a closer look, you will see writing that goes around the sensor. There you will find the size of your Apple Watch.

How To Measure Your Wrist Size?

You'll need: Flexible measuring tape or ruler / String or strip of paper + pen or marker.

Option 1: Use a flexible measuring tape.

With your palm open and facing up, wrap the measuring tape around your wrist, just above your wrist bone. Note down the measurement of your wrist size.

Option 2: Use a string or paper.

With your palm open and facing up, wrap the string or strip of paper around your wrist, just above your wrist bone. Mark where the ends meet with a pen or a marker. Next, lay the string or piece of paper flat and measure it to where you've made the mark to find your wrist size and note it down.
