Understanding office furniture measurements

Choosing office furniture is an exciting process, but at the same time it can be overwhelming. There are many factors to consider before making the right choices. You need to make sure you understand how office furniture is measured and how those measurements are used. How exactly are you going to distribute the furniture in the space that you have? What is the shape and exact dimensions of the space available? What size desk would be best suited to the space? What type of desk would suit your personal day-to-day needs?

This article has been prepared to help with some of these all-important questions.

What is meant by width, height, and depth?

The office industry standard is to display these measurements in the order of width first, height second and depth third. Sometimes the width, height and depth can be misunderstood.

As a standard, these measurements relate to the following:

  • Width (W): The measurement of the product from left to right.
  • Height (H): The measurement from the top of the product to the floor (if it is free-standing) or to the bottom of the product.
  • Depth (D): The measurement of the product from front to back.

The same principle can be applied for most types of office furniture.

Office Desk measurements


The widths of office desks vary, allowing you to choose the right option for your needs. Standard widths include 1m, 1.2m, 1.4m,1,6m and 1.8 m. The most popular width is 1.2 metres wide. Note that minimum width for your desk should be 600mm.  This size is usually used for home desks but is increasingly now used in offices as well.

When deciding on the width of your desk, consider where the desk is going to be located, what equipment you need to put on your desk, and how much free space you need in order to work. Questions to consider might include:

  • Will you be using your desk for long periods?
  • Do you use a desktop or laptop?
  • Will you need to use multiple monitors?


When it comes to the depth of your desk, the industry standard sizes are 600 mm or 800 mm; although you can also now get desks in some ranges that are 700 mm deep. Any of these depths will comfortably house a storage pedestal underneath. As a common example, an office desk with a depth of 800 mm would suit a variety of typical office seating, and you would be able to fit all your computer equipment on the desk space with room to position your keyboard and mouse correctly.

Note, we advise you to check the depth of any under-desk or desk-high storage that you might be using, as you don’t want it to be deeper than the desk itself, otherwise it will stick out. On the other hand, having storage that is too narrow can make it difficult to reach from your desk.


Desks are usually 725mm or 740mm high and deemed suitable for people between 5ft and 6ft tall, assuming the use of a regular office chair. If you require a different height, you could consider a standing desk: these can be used in a seated or standing position. Height adjustable desks are also very popular: they can range from 640mm to 1300mm in height, giving you the flexibility needed for a busy, changing environment.
