The standard height for a fixed commercial office desk in Australia is 720 to 730mm. This height is designed to suit a user of average height sitting in a correctly adjusted chair.
Desk height must align with the user’s body size and chair height to maintain productivity and back health.
What does AS/NZS 4442 require for desk height?
The AS/NZS 4442 standard specifies a working surface height of 720 to 730mm for fixed desks. This dimension provides the baseline for commercial compliance for users of average height. The standard also requires low glare surface finishes to reduce eye strain during sustained visual work.
Why height adjustable desks are the preferred commercial choice
Height adjustable desks accommodate a wider range of body sizes than any fixed height can. They are the correct ergonomic choice for offices with significant height variation in the workforce. Additionally, standing while working is associated with an increase in productivity.
The impact of knee clearance on posture
AS/NZS 4442 requires minimum dimensions for the space below the working surface to support circulation and posture. Integrated storage, CPU holders, or cable management units can reduce this clearance below the compliant minimum. Verifying these dimensions is a critical part of meeting WHS obligations.

Frequently asked questions
How does chair height affect desk height?
The ideal chair height is 18 to 24 inches. This allows users to sit with feet flat on the floor and knees at a 90 degree angle.
What is the standard height for a standing desk?
For users spending 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 too high or too low?
Incorrect height can cause slouching. This leads to muscle strain, fatigue, headaches, and neck pain.
Questions to ask your supplier before you buy
- Does this desk meet AS/NZS 4442 standards for working height and minimum knee clearance?
- Will the addition of cable management or pedestals reduce the leg room below the compliant minimum?
- For height adjustable models, does the desk maintain stability and structural integrity across its full adjustment range?
