What Garmin Watch Size is Best for Me?

The wrist size measurement of any watch is based on the circumference of the wrist. If your wrist measurement falls in between sizes, pick the size closest to your measurement (skip straight to the Garmin Watch Size Charts).

The right size watch is important because if it were the wrong size, you might have to actually abandon the watch. Garmin watches come packed to the brim with a sensor bundle that usually includes things like a cadence sensor, speed sensor, and an array of satellite sensors.
