The Basic Elements

Before laying out the different criteria to design an ADA Compliant Sign, it’s important to get the basics right. Below is a summary of the most important elements of an ADA Signs.


Plate: The plate is the main sign backer that holds all other elements together.

Tactile Lettering: Also referred to as raised lettering, the raised characters forming the sign copy. As per the Americans with Disabilities Act, the tactile lettering should be 1/32”.

Braille: Braille is a system of raised dots that can be read with the fingers. At Elite Letters & Logos we use raster braille for all our ADA Signs.

Pictogram: A pictogram is an image that can be easily identified as the physical object which it is representing. It can also be called an icon, drawing, or symbol. The goal of a pictogram is to be easily recognized, without reading.

ADA Signage Criteria

Now that we have the basic elements of ADA signage clear, let’s move on to the actual signage criteria in order to design ADA Compliant Signs.


Text Size

The text size on each sign in order to be ADA compliant must be a minimum of 5/8” and a maximum of 2”. The text must be raised tactile lettering with a minimum of 1/32”.


All signs that indicate permanent room must have braille. The sign criteria stipulate that the braille must Grade 2. The braille should be a direct translation of the sign and must be placed directly under the copy. For multiple lines of text, the braille shall be located below the entire text.


First of all the text copy must be in all caps. Furthermore the font must be sans serif and cannot be italic, script, bold or decorative in any way.


In order for a sign to be ADA Compliant they must have a non-glare, matte or eggshell finishing. Reflective or glossy finishes are not allowed. Furthermore textures must be kept to a minimum as to not affect legibility. Since the signs are intended to be read by touch they cannot have any sharp or abrasive edges.


An ADA sign must have a contrast ratio of 70 percent between the tactile lettering and the background. This means either dark letters on a light background or the use of light letters on a darker background.
