There are two basic types of Braille, the first is called Grade 1 Braille. This Braille is a letter for letter translation

and should only be used by those that already understand braille well enough to translate the text themselves.

The second type which has become the standard for sign making is Grade 2 Braille.

This Braille consists of abbreviations and conjunctions that are generally accepted.

Where there is no wall space to the latch side of the door, signs shall be placed on the nearest adjacent wall,

mounting height shall be 60 inches above the floor to the centerline of the sign, mount signs so that

a person may approach 3 inches of signage without encountering protruding objects or standing within

the swing of a door. ADA Signage Compliance

The tips below will help keep your signage system in compliance with the Americans with Disabilities Act.

Compliant signs should have raised letters, numbers and Grade 2 Braille. Characters and symbols must offer high

contrast with their backgrounds. Signs should be mounted on the latch side of the door with the centerline 60

inches above the floor. Building directories and temporary signs are excluded from compliance.
