A standard fixed height desk in the UK sits at around 72cm to 75cm from the floor to the top surface. That single figure is the reason so many home working setups are uncomfortable, because it was established as a compromise for an average seated adult and it suits relatively few people precisely without an adjustable chair beneath it.
Depth is the second measurement that determines whether a desk works, and it is more commonly wrong than height. A desk shallower than around 60cm cannot place a monitor at a comfortable viewing distance, which pushes the screen too close and the user too far forward. Width matters least of the three for comfort, and most for whether the desk fits the room.
The convention of roughly 72cm to 75cm predates home working by decades. It assumes the user adjusts the chair to the desk rather than the desk to the user, and that a footrest fills any gap left underneath. Where a chair cannot be raised sufficiently, the user works with raised shoulders. Where it can be raised but the feet then dangle, the user loses support through the thighs.
The correct seated height for an individual is the one that places the forearms roughly parallel to the floor when the shoulders are relaxed and the elbows are at approximately 90 degrees. For a shorter adult, that may be below 72cm, and the practical remedy on a fixed desk is to raise the chair and add a footrest. For a taller adult it may be above 75cm, and the remedy is either a height adjustable desk or raising the desk on sturdy risers.
Height adjustable desks resolve the problem directly, and the range offered on most models covers seated and standing positions for the majority of adults. The standing height to aim for follows the same elbow rule, measured while standing with the shoulders relaxed.
Monitor distance is the reason depth matters. A screen should sit at roughly an arm’s length from the eyes, and that distance has to exist between the front edge of the desk and the screen, with the keyboard in between.
A 60cm deep desk accommodates a single monitor of moderate size with a keyboard in front of it. A 70cm to 80cm desk is required for a larger screen, for a monitor arm that pushes the screen back, or for a dual screen arrangement where the user needs to sit further back to take in both.
Laptop only users can work at shallower depths, which is why compact desks around 50cm deep exist. They are viable for short periods and for occasional use, but they force the screen close to the face because the laptop keyboard and screen are fixed together. Anyone working a full day is better served by a deeper desk with an external keyboard and the laptop raised.
The table below sets out the dimensions commonly used across UK home and office desks and what each configuration supports. These are specification figures rather than measured survey data.
| Desk type | Typical width | Typical depth | Height | Supports |
|---|---|---|---|---|
| Compact or laptop desk | 80cm to 100cm | 45cm to 50cm | 72cm to 75cm | Laptop only, occasional use |
| Standard home desk | 110cm to 120cm | 60cm | 72cm to 75cm | Single monitor and keyboard |
| Full size desk | 140cm to 160cm | 70cm to 80cm | 72cm to 75cm | Large or dual monitors, documents |
| Corner desk | 120cm to 160cm per wing | 50cm to 60cm per wing | 72cm to 75cm | Separated screen and writing zones |
| Sit stand desk | 120cm to 160cm | 70cm to 80cm | Around 70cm to 120cm adjustable | Alternating seated and standing work |
Underneath the desk, allow at least 60cm of clear width and around 60cm of clear depth for the legs, with knee height clearance of roughly 58cm to 65cm depending on the user. A drawer pedestal fitted under a 120cm desk typically removes 40cm of that width, which is the most frequent cause of a desk that measures correctly on paper and feels cramped in use. Where drawers are needed, a mobile unit from our office pedestal drawers UK range can be rolled clear rather than fixed in the leg space.
Most home desks in the UK are not in offices. They are in bedrooms, on landings, in alcoves beside chimney breasts and in corners of living rooms, and the room dictates the format more than the work does.
An alcove beside a chimney breast in a Victorian terrace is often between 70cm and 110cm wide, which suits a compact desk or a made to fit surface rather than a standard 120cm model. A bedroom with a bed against one wall usually has one free wall run, and the desk competes with the wardrobe for it. A corner desk is frequently the resolution, because it takes surface area from a corner that would otherwise be dead space and leaves both wall runs partially available.
Allow at least 75cm behind the desk for the chair to be pushed back and the user to stand, and closer to 100cm where the chair sits in a walkway. Our computer desks UK and corner computer desks UK ranges cover both approaches, and in shared rooms a gaming desks UK format often provides the depth needed for multiple screens in a width that still fits a bedroom wall.
Desk dimensions cannot be assessed in isolation from the chair, because the chair sets the user’s height relative to the surface. A chair with a seat height range of roughly 42cm to 52cm covers most adults against a 72cm to 75cm desk, and an adjustable seat height is the single most useful feature for anyone working at a fixed desk.
Armrests are the other interaction to check. Armrests that cannot pass under the desk apron prevent the user sitting close enough, which reproduces exactly the posture problem the desk height was meant to solve. Measure the clearance under the desk frame and compare it with the maximum armrest height before buying, or choose a chair with removable or height adjustable arms from our home and office chairs UK range.
Set the chair first, then the desk. Sit with the feet flat, adjust the seat until the forearms are level with the desk surface, and add a footrest if the feet no longer reach the floor. This takes a few minutes and resolves most discomfort attributed to the desk itself.
Choose depth according to the screen. Sixty centimetres for a single standard monitor, 70cm to 80cm for large or dual screens, and avoid shallow desks for full day working with a laptop unless the laptop is raised and an external keyboard is used.
Measure the leg space rather than the desk top. Sixty centimetres of clear width and around 60cm of clear depth is the working minimum, and fitted pedestals eat into it.
Leave 75cm behind the desk for the chair, and check that the chair’s armrests clear the desk frame. Free delivery to most UK mainland postcodes applies across our office range, and Returns are available up to 30 days, though a measured alcove avoids the need.
This 2026 reference was compiled by Furniture in Fashion from our editorial assessment as a UK furniture retailer, standard desk manufacturing dimensions used in the UK market, the dimensional principles set out in the BS EN 527 series for office work tables and desks, and the workstation assessment principles established by the Health and Safety (Display Screen Equipment) Regulations 1992. It contains no proprietary sales data, customer data or survey fieldwork. Where individual comfort depends on body dimensions rather than furniture specification, we have described the adjustment method instead of quoting population measurements.

Around 72cm to 75cm from the floor to the top surface on fixed height desks. It is a compromise dimension, so the chair height and a footrest are what adapt it to an individual user.
At least 60cm for a single monitor with a keyboard in front of it, and 70cm to 80cm for a large screen, a monitor arm or a dual screen setup. Shallower desks around 45cm to 50cm suit laptops and occasional use only.
Often yes, because it converts a corner that would otherwise be unused into working surface without extending far along either wall. It also separates the screen zone from a writing or paperwork zone, which a narrow straight desk cannot do.
Set it so that your forearms are roughly parallel to the floor with your shoulders relaxed while standing, which is the same rule used for seated height. Most sit stand desks cover a range of around 70cm to 120cm, which accommodates the majority of adults in both positions.
Allow at least 75cm from the back of the desk chair position to the wall or furniture behind, so the chair can be pushed back and the user can stand. Where the chair sits in a route through the room, closer to 100cm is more comfortable.
