There are many different ADA signs that need to be put up by businesses and buildings in order for these to be compliant. These different kinds of signs are designed with the use of a set of guidelines put together by the government. These guidelines are enforced by the Department of Justice and are aimed at giving people with disabilities signs that they can easily understand.

Signs that are considered ADA compliant often have unique features that make them easy to read with the eyes as well as with the sense of touch. For this to be achieved, these signs have to have contrasting colors, tactile letters that use a specific type of font and even Braille. The letters on these signs are also spaced according to guidelines, have pictograms that are considered standard everywhere and are made with the use of materials that are easy on the eyes.

Pictograms - When it comes to pictograms, internationally recognized symbols have to be used. For example, for locations that need to show people that areas are accessible via a ramp or have accessible elements, the international symbol of accessibility in the right color combination has to be used. Bathrooms, staircases and even no smoking signs should also use easy to recognize pictograms that people with vision impairments can easily feel and understand with their fingers.

Letter Sizes - The letters on these signs have to follow a strict 3:5 to 1:1 width-to-height ratio. Letter or character sizes have to be chosen according to the distance the sign is expected to be read. When you say sign distance, it basically means the combined height and reading distance of the sign. The further the distance, the bigger the letters should be.

Character Spacing - When it comes to layouts, there are standards that also have to be followed. Characters cannot be too condensed, or too extended. These signs cannot have letters that are too far from one another or have strokes that are too thick or thin. ADA rules for characters that are laid out properly include maximum and minimum widths as well as maximum and minimum spaces between characters or letters.
