Safety sign mounting heights: a UK reference

Mounting height matters more than people think. The wrong height makes a sign invisible, unreachable for tactile reading, or in the wrong position for emergency egress.

The general principle (BS 5499-4)

BS 5499-4:2013 is the UK code of practice for safety signs. It recommends signs are mounted with their top edge between 1.7m and 2.4m above the floor. That's eye-level for an average adult standing, with enough vertical range to allow signs above doorways and at staircase landings.

Specific situations

• Above doorways — mount just above the door frame, typically 2.0-2.2m to top edge
• Fire exit signs in corridors — top edge 2.0-2.2m, perpendicular to direction of travel for visibility from the exit approach
• Fire exit signs at the actual exit — directly above the door, with floor-level exit signage on long egress routes
• Floor-level exit signage — bottom edge 0.15-0.3m above the floor — for visibility in smoke (smoke layers form near ceiling first)
• Mandatory PPE at zone entry — top edge 1.8-2.0m, before the worker enters
• Hazard warnings on walls — at the worker's normal eye level for the activity
• Door identification (rooms, offices, accessible toilets) — leading edge at handle height (1500mm) for tactile/braille
• Lift identification — at jamb-side, 1500mm, tactile/braille

Accessible mounting (BS 8300)

For tactile and braille signage, BS 8300-2:2018 specifies:

• Centre of text at 1500mm — handle height for tactile reading without crouching or stretching
• Leading edge on the latch side of the door — so a tactile reader can locate the sign while approaching the door
• 50mm from the door frame — clear of the architrave for tactile access

Variations by user group

Care homes (especially dementia care): standard 1700mm mounting can be invisible to residents with stooped posture. Lower mounting (1200-1500mm) for resident-facing signage is best practice. See our care home signage page.

Schools (primary): consider mounting at child eye-level for resident-facing wayfinding (assembly, dining, playground), but maintain adult-eye-level for safety-critical signage that's primarily for staff.

Industrial high-bay: safety signs at zone entry should be at adult eye level despite high ceilings. Larger sign sizes compensate for distance. Don't mount at ceiling height just because the ceiling is high.

Common mistakes

• Mounting tactile signs above 1700mm (unreachable for tactile reading)
• Mounting fire exit signs at ceiling height in smoky environments
• Mounting wayfinding signs in care homes at standard 1700mm
