The height of your desk should generally be at elbow height. This means: as your elbows are positioned at a 90 degree angle from the floor, measure the distance from the floor to the bottom of your elbow. The desk should be built to this height.
This seems a little too high to me.
Most people find elbow height or an inch below elbow height feels best.
People using a laptop or keyboard might order a desk an inch lower to accommodate the inch added by the keyboard.
inch below below elbow, minus keyboard height sounds right
- Elbow is 40” high
- keyboard is 1.5” high
- So 40 - (1.5 + 1.0) = 37.5”
