Computer Desk Size The standard computer desk has 50 inches in width, a height of 28-30 inches, and a desk depth of 25 inches. The depth of the desk should be generous enough to fit a computer monitor, a keyboard, and a mouse.
What is the length of your desk?
The typical executive desk starts at 60 x 30 x 30 inches (W x D x H) (152 x 76 x 76cm). There really isn't a standard size. That's a good thing because it means you can use different widths and depths and heights to meet your needs, while fitting in to the space you have available for your home office floor plan.
