How high should my desk be when standing?

For standing, desk height should allow your elbows to bend near 90°, wrists straight, and shoulders relaxed while typing and using a mouse. A good ergonomic range for most adults puts the desk surface around 38–46 inches (97–117 cm) from the floor, depending on user height and posture. 

The exact number depends on your height and arm length, so measuring to your standing elbow height is ideal. Adjustable desks such as iMovR standing desks let you fine-tune between sitting and standing positions smoothly.
