Many people choose their desk based on feeling, design, or what "fits" in the room. The result: a desk that looks good – but is too small, the wrong depth, or restricts movement in everyday use. However, the optimal desk size isn't a matter of chance, but can be specifically determined by your usage and the available space.
The most important question is not: "What size is typical?" but rather: "How much space do I need for my work – and how much space do I actually have available?"
A workspace with two monitors requires more than just a wide surface. You also need to consider the depth of the room, the distance to the wall, and the movement zones around the desk. We'll look at exactly that step by step now – so you can find the size that truly suits your setup and your space.
What desk size suits you best? The direct answer
The ideal desk size depends on two factors: your specific work style and the actual available space. Many people base their decisions on catalog dimensions or design specifications – but what really matters is what you need on your desk every day and how much space you have available for it.
The following minimum dimensions apply for screen work with 1 monitor, keyboard, mouse and notepad:
- Width: min. 140 cm
- Depth: min. 80 cm
- Height: approx. 74 cm (or height adjustable from 65–125 cm)
If you work with two monitors or additional devices (e.g., graphics tablet, document holder), you should aim for a screen size of 160–180 × 90 cm . Anything smaller is only suitable for temporary laptop workstations.
However, these measurements are only helpful if your space allows for them. Therefore, your next step should be to determine how much space you actually have available – and how you can use it ergonomically . I'll show you how to do this step by step in the next section.
Step by step: How to determine the right table size
The right desk size isn't determined by standard dimensions, but by your setup and your space. A 160 x 80 cm desk might seem ideal on paper – but if you only have 2 m² of wall space or work with sloping walls, it won't be very helpful. That's why you need a structured approach that's based on your reality:
-
Calculate your actual workspace
Write down what you actually use – every day. A 24" monitor needs about 55–60 cm of width, a keyboard and mouse another 70–80 cm. A DIN A4 pad or a document folder takes up 25–30 cm. If you work with two monitors, anything less than 140–150 cm in width quickly becomes insufficient.
➔ Allow for a safety buffer of 15–20 cm so that you don't have to constantly move things.
-
Check the required depth – and not just the footprint.
The optimal depth depends on the distance between your eyes and the screen: 60–80 cm is recommended. If you place the keyboard in front of it, you need a depth of at least 80–90 cm – anything less leads to cramped posture. Many tables in German households are only 60–70 cm deep – that's sufficient for laptops at best, but not for computer workstations according to DGUV guidelines .
➔ Depth is more important than width – if you have limited space, prioritize here.
-
Measure your room realistically – not just the wall
A table measuring 160 x 80 cm needs approximately 2.5 m of free space in width and 2 m in depth to be used effectively – including space for a chair, legroom, and movement. Also check whether doors, windows, or radiators affect the placement.
➔ A table is not suitable if you constantly get up and bump into things.
Interim result:
Your desk doesn't just need to "fit" – it needs to integrate seamlessly into your space without negatively impacting your posture or workflow. If you honestly consider these three points, the right size will almost become clear on its own – without relying on blanket recommendations.
Standard dimensions at a glance (Germany & EU)
In Germany, there are clear recommendations for computer workstations – regardless of whether you work in an office or at home. The relevant standards are DGUV Regulation 215-410 and DIN EN 527 , which define specific minimum dimensions for ergonomic working.
The following overview shows you which desk sizes have proven effective in practice – sorted by type of use:
| Usage situation | Recommended size (W × D) | Commentary from practice and standard |
|---|---|---|
| Laptop only, occasionally | 100 × 60 cm | Only suitable temporarily, e.g. for guests |
| Laptop + external display | 120 × 70 cm | Minimum requirements for hybrid use |
| Standard PC with 1 monitor | 140 × 80 cm | DGUV-compliant workplace |
| Two monitors or more documents | 160–180 × 80–90 cm | Comfortable for multitasking |
| CAD / Graphics / Large-format works | from 180 × 90 cm | Increased depth for viewing distance |
Note regarding table height:
- Fixed tables: approx. 74 cm
- Height adjustable: 65–125 cm (for switching between sitting and standing)
These dimensions are based on German labor law and are intended for prolonged work at a computer screen. Many standard desks – for example, from furniture stores – fall below these dimensions and are not suitable for extended use at a PC.
Which types of desks are suitable for your room?
| desk type | Typical dimensions (W × D) | Advantages / Notes on room planning |
|---|---|---|
| Classic rectangular table | 140–180 × 80–90 cm | Flexible, space-saving, ideal for individual workstations |
| Sit-stand desk | 120–180 × 80–90 cm, height 65–125 cm | Ergonomically ideal, but sufficient engine displacement and power connection are needed. |
| Corner desk / L-shape | 160–200 × 120 cm (Two surfaces) | It makes optimal use of corners, but requires more wall space. |
| Compact model (e.g. for small rooms) | 100–120 × 60–70 cm | Only suitable for laptop work, limited viewing distance |
| Wing desk (U-shape) | from 200 × 180 cm and more | Suitable for multitasking workplaces, only suitable for large rooms. |
Common mistakes – and how to avoid them
One of the most common mistakes: choosing a desk based solely on design or available space – not on actual needs. Models with a depth of only 60–70 cm, which are frequently found in stores, may look modern, but they don't provide sufficient viewing distance to the monitor. The result: cramped posture, neck pain , and constant rearranging.
Another misconception: "Little space means a small desk." The opposite is often more sensible. A desk that's too small quickly leads to clutter, insufficient document space, and limited mouse movement – especially in home offices with multifunctional workstations.
The issue of hidden usable space is also often underestimated. A 160 cm wide table is of little use if the left half is blocked by shelves or a sloping ceiling. Equally problematic are integrated cable channels or structures that take up valuable space.
Avoid these mistakes by checking the following before you buy:
- Is the full width usable without restrictions from walls, furniture, or technology?
- Does the depth provide at least 80 cm of free space – measured from the monitor stand?
- Have you ever experienced a lack of storage space in your daily life?
Anyone who thinks these points through carefully won't buy a table "made to measure," but one based on function. And that's precisely what makes the difference between a piece of furniture and a workspace.
Conclusion & practical checklist
A suitable desk is not a luxury, but a basic requirement for focused, healthy work – especially with daily screen use. The crucial factor is not the furniture's dimensions, but the usable surface area in relation to your work style and the available space. Those who choose based solely on appearance or price are making a costly mistake.
Use this checklist before you decide on a model:
- Are you using one or two monitors? → Plan for at least 140–160 cm of width.
- Do you work at a screen for more than 2 hours a day? → A desk depth of at least 80–90 cm is necessary.
- Is your room at least 2.5 x 2 m? → Ergonomic use possible
- Do you need space for notes, laptop, accessories? → Include extra width.
- Table height adjustable or adapted? → 74 cm fixed or 65–125 cm adjustable (DIN EN 527)
- Is the full usable area available without obstructions? → No slope, no wall in the way
Even the best desk becomes useless if you combine it with a kitchen chair that's too low. An ergonomic chair is the second key component for a healthy workspace – without it, even the perfect desk will be used inefficiently.
