Getting a desk that will fit perfectly in your office space is vital. It doesn’t mean anything to have a desk that looks amazing but won’t fit in your space.

So, getting the right measurements of the desk is of much importance.

There are several things you should be familiar with before measuring a desk. So, we’ve rounded up all the things that you should need to know about measuring a desk, and created this simple guide.

Let’s get into it.

Desk Measurements

The very first thing you should be familiar with is the desk measurements. Indeed, when you’re trying to buy a new desk, the first thing you want to be sure of is that it will fit in your room.

You don’t want to spend a lot of money on a desk that won’t fit in your room. So, it is vital to make sure that you understand how much space you have in your room.

The three measurements that you should focus on are:

  • Width (W) – The desk’s width is the measurement from its left side to the right side. 
  • Height (H) – The height of the desk is measured from the bottom to the top of the desk. 
  • Depth (D) – Imagine you are sitting behind the desk. The depth is a measurement from the nearest point of the desk to the farthest.
Measurements of a desk


If your height is anywhere from 5ft tall to 6ft tall, then the recommended desk height is 29-30″. That is the most common desk height and it works well for most people.

If you are taller than that or you just prefer to work standing, then the height adjustable standing desks are recommended. These types of desks have an option to adjust the height, either manually or by electric motors.

Pro Tip: When adjusting the height of the standing desk, the height of it should be just below your elbows when you are standing up.


While in many cases the depth of the desk can be ignored, it definitely shouldn’t be. It determines how much space you have available for your monitors, keyboard, and any other things you wish to put on your desk.

If the depth of the desk is too small, you may find yourself in the position that you lack the space for many of the things. On the opposite, if the depth is too big, the monitor can be far away from you or you can find yourself lacking the space in your room because the desk takes up too much space.

The average desk depth is 30″, however, you should think about how much workspace you need before choosing the desk. Maybe 30″ is too narrow for you, maybe it’s too wide, or maybe it’s just perfect.


The final dimension you should focus on is the width of the desk. As for the average number, the average desk width is 60″. Anything smaller than that number will present you with difficulties regarding the space you have for your things. For example, if you have a dual monitor setup then the dual monitor desk should have an even higher width to be able to accommodate the two monitors.

However, if you don’t have that much space in your room, there are smaller-sized desks like this FLEXISPOT 48INCH Electric Height Adjustable Desk.

Additional Factors You Should Consider Before Buying a Desk

While the dimensions of the desks are the most important factor you should look at, there are also a couple of other factors you should consider before purchasing a new desk.

Available Space

When you know the measurements of the desk you want to purchase, or for your DIY desk, the next step is to measure the available space you have for a new desk in the part of the room you wish to put it. This is another crucial step because imagine spending a lot of money on a new executive desk for example and not having the space to put it in. So, we can’t stress this step enough.

Desk Shape

A very important factor that you should think about before purchasing a desk is what shape of the desk do you need. For example, if you don’t have enough amount of space in your room for a big desk, and you have space for a corner (l-shaped) desk, then that is the logical way to go.

Chair Size

This may not sound important, but before you choose your desk, you should definitely take into consideration the size of your chair. If your new desk takes up a lot of space and there is no place for you to put your chair, where are you going to sit? So, think about the space that is left for your chair and if it can fit under your desk.
