o determine correct office meeting table dimensions, allocate a minimum of 600mm to 700mm of linear table width per seated participant. Additionally, maintain a strict 1200mm perimeter clearance between the table edge and any surrounding walls or furniture to comply with Australian workplace accessibility and spatial flow guidelines.
1. Headcount to Dimension Formulas
When purchasing a boardroom or meeting table, buying solely based on room length often creates cramped, unusable spaces. The configuration must scale directly with intended human capacity.
-
For Rectangular/Boardroom Tables: Multiply the number of participants per side by 600mm (minimum) or 700mm (executive standard), then add room for the table ends (approx. 600mm total width).
-
For Round Tables: Use a diameter calculation to ensure knees do not clash beneath the central base or legs.
2. Spatial Footprint Matrix by Seating Capacity
| Seating Capacity | Recommended Rectangular Table Size | Recommended Round Table Diameter | Minimum Required Room Size (With 1200mm Clearance) |
| 4 People | 1200mm x 900mm | 900mm – 1000mm | 3600mm x 3300mm |
| 6 People | 1800mm x 900mm | 1200mm – 1300mm | 4200mm x 3300mm |
| 8 People | 2400mm x 1200mm | 1500mm – 1600mm | 4800mm x 3600mm |
| 10–12 People | 3200mm x 1200mm | Not recommended | 5600mm x 3600mm |
| 14+ People | 4200mm+ x 1400mm | Not recommended | 6600mm+ x 4200mm |
3. Choosing the Right Shape for Room Dynamics
-
Rectangular & Boat-Shaped: The industry standard for formal boardroom tables. Boat-shaped variations taper slightly at the ends, improving sightlines for video conferencing cameras and multi-monitor presentations.
-
Round Tables: Ideal for small breakout spaces, compact interview rooms, or collaborative hubs. For spaces accommodating up to four individuals, deploying a solution like the Orion Round Meeting Table optimizes tight square-meter footprints by eliminating hard, sharp corners that disrupt foot traffic.
4. WHS Clearance and Technology Integration
Do not forget the "Make-Good" and WHS rules of commercial space planning. To ensure your office meeting tables in Perth meet strict building code requirements, factor in these two variables:
-
The 1200mm Clearance Rule: This distance allows an individual to sit comfortably in an extended chair while still leaving space behind them for an active walkway or wheelchair access.
-
Power & Data Cutouts: Ensure large tables are specified with integrated flip boxes or cable spines. Running extension cords across the floor to a wall outlet creates immediate safety violations.
