(We know an average-size mouse won’t work for everyone, but we used this information to check that our panel had a representative spread of hand sizes.) Using hand anthropometric data collected by the Georgia Tech Research Institute (taken from studies conducted in 20), we combined the stated hand measurements to find that the average palm size is 4 inches and the average middle finger length is 2.95 inches. Comfort varies based on hand size, so we sought out average hand measurements for adults. Comfort: To evaluate comfort, we’ve tested mice with panels of left- and right-handed people with various grip types and hand sizes.
