One of the questions that I’ve been asked about the Garmin Forerunner 201 is how big is it? I took out my ruler and measured its dimensions, and I also took a few photographs of it next to a Polar S-710 heart rate monitor for comparison.
The GPS unit that you wear on your wrist is 3 1/4 inches wide x 1 3/4 inches high x 11/16 inch thick (8.25 cm x 4.45 cm x 1.75 cm). The wrist strap is 10 1/4 inches long x 1 1/4 inches wide (26.04 cm x 3.18 cm). It weighs 2.8 ounces (79.37 g) with the wrist strap attached.
By comparison, the Polar S-710 HRM receiver is 1 13/16 inches wide x 1 3/4 inches high x 9/16 inch thick (4.60 cm x 4.45 cm x 1.43 cm). When the receiver is attached, its wrist strap is approximately 10 1/2 inches long x 1 3/8 inch wide at its widest point (26.67 cm x 3.49 cm). The S-710 receiver weighs 1.9 ounces (53.86 g) with the wrist strap attached.
