Details: Tactile & Braille Signs
Signs may incorporate tactile (raised) and Braille information to assist people who have visual impairment. The use of tactile graphics reaches a far wider audience, but in our experience the addition of Braille is a minimal extra over cost and creates a good impression. We regularly use this specification in buildings accessed by the general public although it is not a legal requirement in the UK.
— Keep messages short and jargon free
— The minimum letter size for tactile information is 15mm cap height
— The minimum size for tactile pictograms is 100mm high (where possible)
— Use a simple sans serif typeface and range messages left
— Specify a Braille notch at the start of this part of the message
— Locate signs at the same height and position, pictograms for toilets should be mounted on the door itself with all other signs going to the side of the door on the wall (we generally try to make this the same side as the door handle although this is not always possible).
