The standard height for a fixed commercial office desk in Australia is 720 to 730mm. This dimension is specified under AS/NZS 4442 to suit a user of average height sitting in a correctly adjusted chair.
A fixed height is a baseline, but it rarely accommodates every member of a diverse workforce.
What does AS/NZS 4442 specify for office desks?
The AS/NZS 4442 standard requires a working surface height of 720 to 730mm for seated office work. This ensures structural integrity and functional use for the average adult, provided the user has a compatible chair.
When are height adjustable desks required?
Height adjustable desks are the ergonomically correct solution for offices with significant height variation in the workforce. These desks meet the standard across a wider range of users than any single fixed height can provide.
How does knee clearance affect desk selection?
AS/NZS 4442 specifies minimum dimensions for the space below the working surface to ensure proper posture and circulation. Installing CPU holders or drawers in this area can reduce clearance below the compliant minimum, which is a critical check during the specification process.
How to verify desk height for your team
Visit our Kilsyth or Knoxfield showrooms to test different heights and configurations before ordering. Our design team can also use CAD space planning to ensure your chosen desks fit the layout without compromising leg room.
Frequently asked questions
What is the standard height for a standing desk?
For users who spend most of their time standing or walking while working, a desk height of 36 to 40 inches is recommended.
What happens if a desk is the wrong height?
Working at a desk that is too high or too low can cause slouching, which leads to muscle strain, fatigue, headaches, and neck pain.
How should a chair be adjusted to match a standard desk?
The chair should allow the user to sit with feet flat on the floor and knees at a 90 degree angle, typically with a seat height between 18 to 24 inches.
