How to measure your space before buying a corner desk
By James Whitfield, Melbourne
Before buying a corner desk, take five measurements: the usable length of both walls at the corner, the clearance behind the desk for your chair (allow at least 1 metre), the walkway you need to keep open (600 mm minimum, 900 mm to be comfortable), the position of power points and windows, and the door swing. Then check those numbers against real desk footprints — L-shaped corner desks commonly run from around 1800 × 1600 mm up to 2400 mm along the long wall, which is a lot of furniture to discover doesn't fit on delivery day. Here is the step-by-step method, with actual dimensions from Desk One's fixed corner desk range as worked examples.
A corner desk is the hardest furniture item in the house to eyeball. It occupies two walls at once, its clearance zone sits inside the room rather than against a wall, and unlike a straight desk you can't just slide it along to make things fit. Ten minutes with a tape measure prevents the two classic failures: a desk that physically doesn't fit, and a desk that fits but leaves no room to sit at it.
Step 1: Measure both walls — from the corner outward
Run the tape from the corner along each wall and note where the usable length ends: at a window frame, a wardrobe, a door architrave or a power outlet you can't block. Those two numbers — long wall and short wall — are your hard limits. Record them wall by wall, because L-shaped desks are specified the same way: a desk listed as 1800 × 1600 mm needs 1800 mm along one wall and 1600 mm along the other. Note which side is which, too. Some corner desks are offered in left- or right-hand orientation, so the long arm has to land on the wall that actually has the length.
Step 2: Check the skirting, sills and sockets
Walls are rarely clean rectangles at desk height. Skirting boards push the desk out from the wall by a couple of centimetres; window sills can sit at or below desk height and block the desktop from sitting flush; power points and data outlets behind the desk either need clearance or become unreachable. Measure the height of anything that protrudes from each wall below about 780 mm — the typical fixed desk surface sits around standard desk height, and executive corner desks with hutches rise well above it. If a window starts low on one wall, plan for the desk's lower arm or storage side on that wall, and check the specific desk's height figures on its product page.
Step 3: Mark the chair and circulation zone
The desk footprint is only half the space a corner desk consumes. From the inner edge of the desk, allow at least 1000 mm of clear depth for the chair — enough to sit down, roll back and stand up without hitting anything. Beyond the chair zone, keep a walkway of at least 600 mm if the route past the desk is occasional, or 900 mm if it's the main path through the room. Painter's tape on the floor is the honest test: tape the full desk outline plus the metre of chair zone, and live with it for a day. If the taped shape makes the room feel blocked, the desk will too.
Step 4: Doors, drawers and the delivery path
Check the swing of the room door and any wardrobe doors against your taped outline. Then think about the desk's own moving parts: executive corner desks typically carry drawers and cabinet doors on the inner side, which need clearance to open with the chair in place. Finally, measure the delivery path — hallway width, stair turns, the door into the room. Corner desks arrive as large flat-packed boxes; the room the desk fits into still has to be reachable.
Step 5: Check your numbers against real footprints
With your wall lengths and clearance zones written down, compare them against actual desks. The table below shows the fixed-height L-shaped executive corner desks in Desk One's current range — useful as worked examples of how much wall each size class consumes, whatever you end up buying.
| Model | Footprint (per product listing) | Storage configuration |
|---|---|---|
| Desk One A003 L-Shaped Executive Corner Desk | 1.8 m × 1.6 m or 2 m × 1.6 m (two sizes; left or right orientation) | Drawers, lockable cabinet, PC compartment |
| Desk One A008 L-Shaped Executive Corner Desk with Hutch | 2000 × 1800 mm | Hutch, dual drawers, PC compartment, password lock |
| Desk One S901 Corner Desk with Storage | 2400 mm L-shaped workstation | Integrated storage, drawers, PC compartment |
| Desk One S902 L-Shaped Executive Corner Desk | 2400 mm corner workstation | Side cabinet, drawers, PC compartment |
Reading the table against your measurements: the A003 at 1.8 × 1.6 m is the compact end of the executive class and the two-size, two-orientation options give it the best chance of fitting an awkward corner; the A008's 2000 × 1800 mm footprint plus hutch needs both generous walls and vertical clearance; and the 2400 mm S901 and S902 are full-scale workstations that want an uninterrupted 2.4 m run of wall. Depths and heights for each model are on the product pages — check them against your Step 2 notes. The full range sits in the corner and L-shaped desk collection.
One clarification: fixed height vs motorised corner desks
The desks above are fixed-height executive corner desks — the desktop sits at standard desk height, and the buying decision is purely about footprint, storage and finish. That's a different category from motorised corner desks: L-shaped sit-stand desks that adjust height electrically, where you also need to think about cable slack and clearance under window sills at the standing position. If you're weighing fixed against motorised, our guide to the best L-shaped corner desks in Australia covers both camps, and the best corner desks for home offices guide ranks options by room size. The measuring method in this article applies to both — a motorised desk just adds a vertical measurement to Step 2.
A worked example
Say your spare room offers 2100 mm along the window wall before the frame starts, and 1700 mm along the side wall before the built-in wardrobe. The A008 at 2000 × 1800 mm fails on the second wall (1800 needed, 1700 available). The A003 in its 2 m × 1.6 m size fits with 100 mm spare on each wall — but only in the orientation that puts the 2 m arm on the window wall, so you'd order accordingly, then tape out the footprint plus a metre of chair zone to confirm the room still walks. That's the whole method: measure, compare, tape, order.
FAQ
Q: How much space do I need for a corner desk?
A: Add three zones: the desk footprint itself (commonly 1800 × 1600 mm up to 2400 mm along the long wall for L-shaped executive desks), at least 1000 mm of chair clearance from the desk's inner edge, and a walkway of 600–900 mm past the setup if the room's main path runs by it.
Q: How do I read a corner desk's dimensions?
A: A listing like 1800 × 1600 mm means the desk needs 1800 mm along one wall and 1600 mm along the other. Measure both walls from the corner outward to the first obstruction, and check whether the desk is offered in left- and right-hand orientations so the long arm lands on your longer wall.
Q: What sizes do Desk One's fixed corner desks come in?
A: Per the product listings: the A003 comes in 1.8 m × 1.6 m and 2 m × 1.6 m with left or right orientation, the A008 with hutch measures 2000 × 1800 mm, and the S901 and S902 are 2400 mm L-shaped workstations. Depth and height details for each are on the product pages.
Q: How much clearance do I need behind a desk for the chair?
A: Allow at least 1000 mm from the desk's inner edge. That covers sitting down, rolling back and standing up. If people also need to walk behind the seated chair, add a further 600 mm minimum — 900 mm for a comfortable main walkway.
Q: Are corner desks height adjustable?
A: The executive corner desk category — including Desk One's A003, A008, S901 and S902 — is fixed height, at standard desk level. Height-adjustable corner options are a separate category: motorised L-shaped sit-stand desks, which adjust electrically and need extra vertical clearance planning around window sills and cabling.
Q: What's the most common corner desk buying mistake?
A: Measuring only the desk footprint and forgetting the space around it — chair clearance, door and drawer swings, and the walkway. The reliable fix is painter's tape: mark the full desk outline plus a metre of chair zone on the floor and live with it for a day before ordering.
