Understanding Standard Safety Sign Sizes
Safety signs come in various sizes, typically based on the A-series paper sizes (A5, A4, A3, etc.). The size you need depends on the viewing distance and the complexity of the message.
Here's a quick breakdown:
- A5 (148 x 210mm): Suitable for close viewing distances (up to 5 metres). Ideal for door signs or signs with simple messages.
- A4 (210 x 297mm): A common size for general safety signs, visible up to 10 metres. Use for mandatory signs and warning signs.
- A3 (297 x 420mm): For larger areas or where signs need to be seen from 10-20 metres. Good for fire action signs or detailed instructions.
- Larger sizes (A2, A1, etc.): Use these for viewing distances over 20 metres, or in complex environments like warehouses. Consider for site safety signs or construction site signs.
| Item | Quantity | Notes |
|---|---|---|
| Door Signs | 1-2 per door | A5 size is often sufficient |
| Mandatory Signs | Varies by area | A4 is a good starting point |
| Fire Action Signs | 1-2 per floor | A3 for clear visibility |
Quick Tip: Consider the complexity of the message. If you need to include a lot of information, go for a larger size.
Next, we'll look at how viewing distance affects your sign size choice.
How Viewing Distance Impacts Sign Size
The further away someone is from a sign, the larger it needs to be to remain legible. Consider the areas where people will be viewing the signs from when deciding on the size.
As a general rule:
- Up to 5 metres: A5 size is usually adequate.
- 5-10 metres: A4 size is recommended.
- 10-20 metres: A3 size is best.
- 20+ metres: Consider larger sizes or multiple signs.
For example, in a warehouse, hazard signs near machinery should be large enough to be seen from a distance, even with forklifts moving around. You'll likely want A3 or larger.
| Item | Quantity | Notes |
|---|---|---|
| Hazard Signs | As needed near hazards | A3 or larger for warehouses |
| Fire Exit Signs | At each exit | Consider viewing distance for size |
Quick Tip: Walk around your premises and note the typical viewing distances for different areas. This will help you choose the right size.
Let's look at specific sign types and their recommended sizes.
Recommended Sizes for Common Safety Signs
Certain types of signs have typical size recommendations based on their purpose and placement. Here's a guide to some common signs:
- Fire Exit Signs: A4 is standard, but use A3 or larger for long corridors or areas with poor lighting. You'll need these at each fire exit.
- Fire Action Signs: A3 is recommended for clear visibility of instructions. Typically, you'll want one per floor, near fire alarm points.
- PPE Mandatory Signs: A4 is usually sufficient at entry points to areas requiring PPE. Install at each zone entry point.
- Warning Signs: A4 or A3, depending on viewing distance and the severity of the hazard. Place these near the specific hazard.
- First Aid Signs: A4 is standard, but consider A3 for larger facilities. Ensure one is clearly visible near the first aid station.
| Item | Quantity | Notes |
|---|---|---|
| Fire Exit Signs | 1 per exit | A4 standard, A3 for long corridors |
| Fire Action Signs | 1 per floor | A3 recommended |
| PPE Mandatory Signs | At each zone entry | A4 is usually sufficient |
Quick Tip: Photoluminescent (glow-in-the-dark) signs are essential for fire safety, especially for fire exit routes.

Frequently Asked Questions
What's the best material for safety signs?
Rigid plastic is durable and suitable for most indoor and outdoor applications. Self-adhesive vinyl is good for smooth surfaces like doors. Photoluminescent material is crucial for fire safety signs, ensuring they're visible even in a power outage. Consider aluminium signs for premium look and durability.
How high should I mount safety signs?
Typically, mount signs at a height of 1.8 to 2 metres from the floor. This ensures they are easily visible without being obstructed. Adjust the height as needed based on the specific location and potential obstructions.
