For people who are between 5 feet, 8 inches and 5 feet, 10 inches tall, the proper height for a computer desk should be anywhere between 28 and 30 inches. But people who are shorter or taller than this height range may have a hard time with these types of desks. For offices that have a lot of employees with varying heights, it might be a good idea to get desks that can be adjusted in a way that will accommodate them.
