How High Should a Desk Be? Dimensions and Ergonomics Guide

July 4, 2026

The standard height for a fixed desk in Europe is 72 cm, which is ergonomically ideal for individuals with a body height of 165 cm to 175 cm.

Anyone planning a workspace or assembling furniture themselves must match the dimensions precisely to their body and room proportions. An incorrect desk height leads to muscular tension in the long run, whilst unsuitable worktop measurements restrict the room both visually and functionally. This guide explains the correct dimensions, selection criteria for the home office, and the most important aspects of self-assembly.

Dimensions & Suitability: Determining the Correct Height

Ergonomics at the workstation starts with seating posture. When sitting upright with feet flat on the floor, your upper and lower legs should form an angle of at least 90°. The same applies to the arms: when forearms rest loosely on the worktop, upper and lower arms should also be at a 90° angle to each other. The shoulders remain relaxed.

Guidelines for desk height based on body height:

Body height 160 cm: approx. 66 cm desk height
Body height 170 cm: approx. 71 cm desk height
Body height 180 cm: approx. 75 cm desk height
Body height 190 cm: approx. 79 cm desk height

Since rigid desks are usually standardised at 72 cm to 75 cm, fine adjustment is often only possible via the office chair or a footrest. The technically cleaner solution for differing body sizes or alternating between sitting and standing is a height-adjustable desk. Here, electric motors in the desk frame handle the height adjustment, usually continuously within a range of 70 cm to 120 cm.

Width and Depth of the Worktop

Alongside height, surface area defines practical utility. For a full workstation with a monitor, a depth of at least 80 cm is recommended to maintain the necessary viewing distance to the screen (approx. 50 cm to 70 cm). Popular standard dimensions for the home office are worktops measuring 120 cm x 80 cm or 160 cm x 80 cm.

For alcoves or rooms with limited space, a format of 120 cm x 70 cm is often sufficient. If the table is only used for a laptop, a model that is 90 cm wide and 60 cm deep will also suffice.

How to Choose: Materials and Construction

When building a desk, the material determines stability and weight. Most modern models consist of melamine-coated chipboard. These panels are resistant to scratches and easy to clean. Those seeking a more natural look and higher load-bearing capacity for heavy monitors choose a wooden desk. However, solid wood panels move with temperature fluctuations and require regular maintenance with oil or wax.

Special rules apply to growing users. A children's desk should ideally grow with the child. Mechanically adjustable frames that adjust via notches or crank mechanisms are sensible here, starting from a height of around 55 cm.

Solutions for Storage and Cable Management

Tangled cables on a worktop look like an untidy workbench – they block workflow. When planning the workstation, cable routing should be taken into account directly. Many worktops do not feature cable ports from the factory. Using a hole saw, this can easily be retrofitted during assembly.

For passing through standard plugs (mains plugs, HDMI), a desk cable grommet 60mm is often sufficient. However, if numerous cables or bulky power supply plugs need to be grouped together, a desk cable grommet 80mm is the safer choice. The matching cable grommet for desk made of plastic or metal is simply pressed into the worktop from above after drilling.

If the desk also needs to serve as storage space, combining it with cabinetry is essential. A desk with drawer provides space for pens and flat documents. The drawers usually run on metal single-extension runners or full-extension runners screwed to the side panels. For lever arch files or larger items, an integrated desk cupboard is recommended, where a side pedestal takes over the function of a table leg.

Assembly Notes for DIYers

Assembling a desk takes between 45 and 90 minutes depending on the model. Lay out the components on a soft surface (e.g. the shipping carton) to avoid scratches on the finish.

Required tools:

Cordless screwdriver with bits (usually PZ2 for wood screws or hex key / Allen bits for frame fixings)
Cross-head screwdriver for fine adjustments
Rubber mallet for wooden dowels
Tape measure

When assembling worktops and side panels, ensure the correct alignment of the cam and pin fittings. The bolt is screwed into the pre-drilled thread, the counterpart (the cam lock casing) is inserted, and it is locked with a half turn clockwise. Do not tighten screws on metal frames fully until all threaded bolts are lightly engaged. This prevents the frame structure from jamming or misaligning.

FAQ: Frequently Asked Questions About Desk Dimensions

How high should a desk be for a body height of 180 cm? For a body height of 180 cm, the ergonomically correct desk height is around 75 cm to 76 cm. At this height, forearms can rest comfortably at a right angle on the worktop.

How deep should a desk be at minimum? For use with an external monitor, the depth should be at least 80 cm. For pure laptop use or in very tight spaces, a depth of 60 cm to 70 cm is also adequate.

Can I drill a cable grommet hole into the worktop myself? Yes. You will need a power drill and a suitable hole cutter (hole saw) matching the exact diameter of the grommet, for example 60 mm or 80 mm. Drill through the chipboard from above using light pressure to prevent the surface coating from splintering.
