Evacuation Diagram Sizes In Australia

In Australia, the required sizes of evacuation diagrams are guided by AS 3745:2010 – Planning for emergencies in facilities. The standard specifies minimum requirements so that the diagrams are clear, legible, and compliant.

​

📏 Evacuation Diagram Sizes

​

1. Minimum Size (A4)

   • The smallest permitted size is A4 (210mm × 297mm).

   • This is allowed only if the diagram remains clear, legible, and readable from the normal viewing distance.

2. Recommended Size (A3)

   • The most common and preferred size is A3 (297mm × 420mm).

   • This size provides better clarity and allows inclusion of all mandatory items (e.g., “You Are Here” point, exits, fire equipment, assembly areas, legend, site address, etc.).

3. Larger Sizes

   • For complex buildings (e.g., hospitals, large schools, shopping centres, airports), evacuation diagrams can be printed in A2 (420mm × 594mm) or even larger, to ensure legibility.

​

📌 General Rules

• Content clarity is more important than size – the diagram must be easily readable.
