Office Desk Sizes in Australia: Standard Width, Depth and Height
A standard office desk in Australia is about 1200–1800 mm wide, 600–800 mm deep and 720–750 mm high. Monash University's Ergonomic Design Standard, citing AS/NZS 4442:2018, uses an 800 mm depth and 730 mm height for its standard desks and at least 1500 mm of length for computer work, while compact home-office desks are usually 1200 × 600 mm.
Those numbers only help once you know what each size does in practice. This page is a quick reference: width by how many screens you run, depth by monitor size, height by how you work, and the floor space each desk needs around it — with the measured sizes of Desk One's in-stock models and links to our detailed guides on each dimension.

Desk width: how many screens fit
Width decides what the desk can hold. Screen widths below are approximate for 16:9 monitors with thin bezels: a 24-inch screen is around 540 mm wide and a 27-inch around 610 mm.
| Width | What fits | Desk One examples (in stock) |
|---|---|---|
| 1200 mm | Laptop plus one monitor. Two 24-inch screens (about 1080 mm) fit edge to edge, but tightly. | LiteEdge, Compact Office Desk, Digger's Den (1200 × 600); S-Series sit-stand (1200 × 750) |
| 1400 mm | Two 24-inch screens with room either side, or a laptop beside a 27-inch. | LiteEdge, Compact Office Desk (1400 × 600) |
| 1500–1600 mm | Two 27-inch screens (about 1220 mm) plus a notepad. Monash's minimum length for computer-only desks is 1500 mm. | S-Series sit-stand (1500 × 750); X-Series (1600 × 800) |
| 1800 mm | Three 24-inch screens (about 1620 mm), or two screens plus paperwork. Monash recommends 1800–2100 mm for mixed tasks. | S-, C- and U-Series tops (1800 × 750); X-Series (1800 × 800) |
| 2000–2400 mm | L-shaped and executive layouts with separate computer and writing zones. | A003 (2000 × 1600 L-shape); A008 (2000 × 1800); S901 and S902 (2400 mm L-shape) |
OSHA advises keeping monitors no more than 35 degrees to either side of straight ahead (OSHA: Monitors), so a third screen usually works better angled in on a wide desk or across the corner of an L-shape than in one long flat row. For more detail, see choosing a desk for a dual or multi-monitor setup and compact desks at 1200–1400 mm.
Desk depth: viewing distance and monitor size
Depth is about your eyes. OSHA says work surface depth should let you view the monitor from at least 50 cm, with a preferred viewing distance of 50–100 cm (OSHA: Desks). Because you sit back from the front edge, a desk does not need to be as deep as the viewing distance.
| Depth | What it suits | Desk One examples (in stock) |
|---|---|---|
| 600 mm | Laptop or one monitor up to about 24 inches; a monitor arm frees more space. Best for tight rooms. | LiteEdge, Compact Office Desk, Digger's Den; Mobile Standing Desk (750 × 600 surface) |
| 700 mm | One or two standard monitors on stands with a keyboard in front. | Nearest Desk One depths are 600 and 750 mm |
| 750 mm | Dual monitors on stands, keyboard and a little writing space. | S-, C- and U-Series sit-stand desks and tops |
| 800 mm | Larger or multiple monitors. Monash's standard depth, which it describes as adequate for one or more standard-size flat monitors. | X-Series (1600 or 1800 × 800) |
If depth rather than width is your limit, read desktop depth options for narrow spaces and choosing a desk for a small bedroom or spare room.
Desk height: fixed and adjustable
| Desk type | Height | Reference points |
|---|---|---|
| Fixed seated desk | About 720–750 mm | Monash: 730 mm, citing AS/NZS 4442:2018. RMIT's workstation guidance: 680–720 mm. Desk One's fixed and executive desks: 750 mm. |
| Sit-stand desk | Adjustable range | Monash: minimum range 620–1200 mm. Desk One: 700–1150 mm (single motor), 700–1200 mm (dual motor), 620–1270 mm frame travel (X-Series triple-stage frame and triple-motor L-shaped desk). |
| Mobile standing desk | 755–1255 mm | Desk One Mobile Standing Desk |
A height standard describes the furniture, not you. RMIT's guidance says you should sit with feet flat on the floor and elbows level with or slightly above the work surface (RMIT Workstation Guidance), so the right fixed height depends on your body and chair. Monash notes that sit-stand desks can go lower than standard height to accommodate all users. Our guides is 70 cm too high for a desk? and setting up a computer desk ergonomically go further, and our standing desk height chart by body height gives sitting and standing settings for each height.
Leg room under the desk
OSHA's minimum clearance under a desk for a seated user is 52 cm wide, 44 cm deep at knee level and 60 cm deep at foot level (OSHA: Work Space). Monash sets a minimum clear leg space width of 800 mm. That matters when you add storage:
- A 400 mm-wide pedestal under a 1200 mm desk leaves about 800 mm of the desk's width for your legs, less the frame. That is right at Monash's minimum, so on a 1200 mm desk consider a pedestal beside the desk, or step up to 1400 mm.
- Desk One's Mobile Filing Pedestal is 400 × 400 × 590 mm and the steel Compact Mobile Pedestal is 390 wide, 500 deep and 600 mm high. The desk pages don't list the clearance under the frame, so measure if the desk has a rail.
See desk drawers vs a mobile pedestal for the storage trade-offs.
How much room does a desk need?
A desk takes more floor than its footprint. Allow the desk depth plus about 1000 mm behind it for the chair, so you can sit down, roll back and stand up. Keep a walkway of 600 mm for occasional access or 900 mm for a main path. In planned offices, Monash uses 1000 mm as the minimum unobstructed access way, 900–1000 mm for entrances to workstations, and about 6 m² per workstation plus storage and corridors.
| Desk size | Desk plus chair zone (approx.) | Floor area |
|---|---|---|
| 1200 × 600 mm | 1.2 m wide × 1.6 m deep | About 1.9 m² |
| 1400 × 600 mm | 1.4 m × 1.6 m | About 2.2 m² |
| 1500 × 750 mm | 1.5 m × 1.75 m | About 2.6 m² |
| 1800 × 800 mm | 1.8 m × 1.8 m | About 3.2 m² |
| L-shaped, 1800 × 1600 mm | Both walls, plus 1 m of chair zone inside the L | Measure the corner |
To compare the two corner layouts first, see L-shaped desk vs corner desk by room size. For corners, follow how to measure your space before buying a corner desk or, for electric corner desks, measuring a wall corner for an L-shaped standing desk. For two to four people, the 2–4 person workstation layout guide works through rows and islands.

Frequently Asked Questions
What size is a standard office desk?
Usually 1200–1800 mm wide, 600–800 mm deep and 720–750 mm high. Monash University's design standard uses 800 mm deep and 730 mm high, citing AS/NZS 4442:2018, with at least 1500 mm of length for computer work. Compact home desks are commonly 1200 × 600 mm.
How deep should an office desk be?
600 mm handles a laptop or a single monitor of about 24 inches; 750–800 mm is more comfortable for two screens or larger monitors. OSHA says the depth should let you view the screen from at least 50 cm.
How wide should a desk be for two monitors?
About 1400 mm for two 24-inch screens and 1500 mm or more for two 27-inch screens, which together measure around 1220 mm. A 1200 mm desk takes two 24-inch screens only edge to edge.
What is the standard desk height in mm?
Fixed desks are typically 720–750 mm. Monash uses 730 mm, RMIT's guidance recommends 680–720 mm, and Desk One's fixed desks are 750 mm. Sit-stand desks cover a range instead; Monash specifies at least 620–1200 mm.
Which height-adjustable desk fits a 160 × 79 cm space?
A 1500 × 750 mm top fits inside 1600 × 790 mm. Desk One's S-Series Single Motor Sit-Stand Desk in that size is from $463.50 and the S-Series Dual Motor from $538.50 (as at 31/10/2026); both have four programmable height presets. The 1600 × 800 mm X-Series is 10 mm too deep. Frame foot length isn't listed, so measure if walls box the space in.
This guide is general information about furniture sizes and workstation setup, not medical advice. If you have pain or a condition that affects how you sit or stand, ask a physiotherapist or occupational therapist to check your setup.
