What size office desk do I need?

Finding the right desk is about more than the style - you need to ensure the size of your desk suits your space, how you're using it and the way you work.

Whether you’re setting up a new home office, replacing an old desk or putting your company’s workspace together, you want to make sure you’re choosing the right sized desk for your needs and your workplace. 

There are a fair few considerations you need to take into account when choosing a desk, let alone deciding how big it needs to be. From the room that you have available to what you’ll be using the desk for and how you like to work, you need to answer a fair few questions before buying your desk. 

To help ensure you pick the right size and find your perfect desk, we’ve taken a look at some of the frequently asked questions we encounter to provide you with helpful and practical advice. 

Understanding desk measurements

The first place you need to start is ensuring you know how to measure a desk, as this will affect how you measure the available space. Often, people get confused between the width and the depth, which can mean they end up buying the wrong sized desk. 

Here are the basic measurements you’re looking for: 

  • Width (W) - The measurement of the desk from left to right when you are looking at it as you would when using it.
  • Height (H) - The measurement from the base to the top. Often, this is a standard measurement. 
  • Depth (D) - The measurement from back to front when you are looking at the desk as you would when using it.

Keeping these in mind should help you understand measurements when buying a desk online, as well as enable you to accurately measure your space. But what sizes should you be looking for when it comes to the height, width and depth?

What should the height of my desk be?

As a standard, if you're between 5ft and 6.5ft tall then the height of your office desk needs to be between 712mm to 762mm for you to sit comfortably when using a regular task chair. 

Most office desks tend to be around 730mm high, meaning they can be used for most people. However, if you are tall enough that this height doesn’t suit you, you may want to look at adjustable desks instead. 

Height adjustable desks allow you to move the desk top so it can be used in a comfortable sitting or standing position. This is ideal if you want to avoid sitting at your desk for long periods of time, or if you need to adjust it to allow for your height or chair type. 

Whichever desk you choose - regular or adjustable - you want to ensure that the height is comfortable and that you are able to either sit or stand without hunching over when using it. 

What should the depth of my desk be?

Often, the depth of a desk gets forgotten about or isn’t seen as being as important as the height of width. However, the depth of your desk is vital when it comes to ensuring you have enough space to be able to work while providing adequate room for the equipment you need. 

The depth of your desk should be between 508mm and 762mm, with a width of at least 610 mm. It is better to have extra space than too little, which is why the narrowest desks we offer are those in our Home Work range, all of which have a depth of 600mm, making them ideal for smaller spaces. 

If you’re using your desk for typing and computer work, the recommended depth is between 712mm and 762mm to ensure you have enough space for your equipment and that you can set your desk up correctly. 

Our standard office desks have a depth of 800mm, which should be the maximum you need. This enables you to fit all your computer equipment on your desk and position your keyboard and mouse correctly to reduce strain. 

You’ll also want to check the depth of any under-desk or desk-high storage you’re going to be using, as you don’t want it to be deeper than the desk itself so it sticks out. Similarly, having storage that is too narrow can make it difficult to reach from your desk.

How wide should my office desk be?

As stated above, the minimum width for your desk should be 610mm. Any smaller than this and you’ll struggle to use it for much of anything. 

You need to consider where your desk will be set up, what equipment you need to put on it and how much you’ll be using your desk. If you are using your desks for long periods, it may be that you need a slightly wider desk in order to be practical.

If you have limited space in which to fit a desk and office storage, you might want to opt for smaller desk and a desk-high filing cabinet or storage pedestal. This will provide you with adequate storage as well as a larger work surface (when you position the storage next to your desk), so you can easily find room for all of your computer equipment.  

Our desks are available in a range of widths to suit your needs. The Home Work desks come in widths of 790mm to 1155mm and our standard office desks coming in widths of between 800mm and 1800mm.

How do I decide how big my desk should be?

Now that you understand the recommended desk measurements, you need to think about what will work best for you. There are a few different considerations that you need to bear in mind, which will likely impact the size of the desk you go for. These include:

  • Available space - Where is your desk going and how much room do you have? 
  • Your chair - When measuring your available space and looking at desks, you need to factor in the room you’ll need for an office chair.
  • How you are using your desk - Is your desk for everyday use or just needed occasionally? Are you using it for computer work, art or something else?
  • What equipment needs to fit on it? - If you need to set up a computer on your desk, you may want to measure how much space all of your equipment will need and the correct way to set up a computer desk.
  • What shape desk do you need? - Are you after a square or rectangular desk or would a wave or corner desk suit your working style and space better?
  • What is your budget? - You may fancy a huge desk, but if it isn’t within your budget, this probably isn’t the best option.

Once you have answers to each of these, you should have a better idea of how big your desk needs to be, as well as some minimum and maximum measurements. You’ll then be able to focus on the style of desk you want and ensure that you can get your dream desk in the right measurements.
