How to Design ADA Compliant Signs

The Value of ADA Signage


ADA Exit Sign

Proper ADA signage in public spaces is required by The Americans with Disabilities Act of 1990 (ADA) to help ensure that persons with visual, hearing, or other sensory disabilities are able to locate and read them easily, either visually or through braille or tactile touch (raised letters). In addition to improving mobility and independence for these individuals, ADA signage also supports safety in public places by ensuring that entrances and exits are clearly marked, visible, and distinguishable from other rooms.

The Basics of ADA Signage

According to the ADA, signs that must be ADA compliant include, but are not limited to, the following:

a) All informational signs (for example “Employees Only”)

b) All directional signs (for example “Exit to Lobby”)

c) All overhead signs (for example “Elevators”)

d) Signs that identify permanently dedicated rooms that will not change function, such as a lunch room, conference room, restroom, or closet

e) Signs highlighting the location of building floors, stairwells, and all exit levels

f) All restroom signs

ADA Signage Requirements

While there are many universal ADA signage requirements, it is important to check individual state laws that may have sign modifications or additional standards.

Where are ADA signs required?

ADA signs are required throughout all public access and employee areas.

Do ADA signs require braille or tactile letters?


ADA Lactating Room Sign

ADA signs must include braille and tactile (raised) letters. Braille letters must be Grade 2 (shorthand braille), rounded/domed, and lowercase (other than proper nouns, letters that are part of a room number, initials, acronyms, or before the first word of sentences) and include a minimum 3/8 inch clearance on all sides. Tactile lettering must be 1/32 inch raised capital letters.

Since braille is a translation of words, signs that depict symbols or pictograms ONLY do not require braille.

Are there additional lettering specifications for ADA signs?

ADA signs must use sans-serif or other plain text and include spacing of 1/8 inch between adjoining characters for easy readability. Text height must be between 5/8 and 2 inches and printed in medium or bold font.

What makes ADA signs easily visible?

ADA signs must be made of high contrasting colors (dark/light or light/dark) for easy readability. Additionally, all signs (other than traffic and reflective parking signs) must have non-glare backgrounds and characters.

What symbols are ADA-approved for use on signage?

ADA signs may include any of the four approved accessibility symbols for pictograms:

a) Wheelchair, symbolizing mobility

b) An ear, signifying the availability of an assistive listening device

c) Keyboard, representing a text telephone (TTY)

d) Phone symbol with sound waves, representing the availability of a volume control phone

Pictograms must include a 6 inch high background area with nothing inside other than one of the four approved symbols described above.

a)Text descriptions are required for signs that include a pictogram and label rooms or spaces
<!- ->*Signs with pictograms that provide information about a space do not require text.

b) Tactile text should be directly under pictogram

c) Braille text should be directly under tactile letters

Does the ADA have special installation requirements?

The ADA lists specific installation requirements, depending on the type of sign. Generally, ADA room identification signs must be placed next to the doors they refer to, mounted between 48 inches, measured from the bottom of the lowest tactile character, and 60 inches, measured from the bottom of the highest tactile character, from the ground.

What is required for ADA parking signs?

All ADA parking signs must include the International Symbol of Accessibility, or “Wheelchair Symbol.” Signs need to be mounted a minimum of 60 inches from the floor measured from the bottom of the sign. Spaces set aside for vans must include the additional text “Van Accessible.”

According to the US Department of Justice Civil Rights Division, ADA signs are signs specifically made so that individuals, including those with visual or other sensory disabilities, are able to easily locate and read them, visually or through braille or tactile touch.

ADA signs are specially designed to be posted in most public buildings (specified below) that ensure that individuals with disabilities will have equal access to public buildings as do those without disabilities. ADA signage is required to present the same information to all people irrespective of physical limitations.

Why ADA Signage is Necessary

Design Your Own ADA SignsFederal Law mandates that all public buildings and spaces must maintain proper, up-to-date ADA signage throughout their facilities. The Americans with Disabilities Act of 1990 (ADA) was enacted to strictly prohibit “discrimination against people with disabilities in employment, transportation, public accommodation, communications, and governmental activities.”

Another key reason that ensuring ADA compliant signage is properly posted throughout your buildings is to eliminate the possibility of your organization being charged with lawsuits, government penalties, and fines. While ADA requirements are simple to follow, many facilities fail to take the time or make the effort to post the appropriate signage and end up facing unnecessary and expensive consequences.

What Buildings Qualify as Commercial Buildings Needing Proper ADA Signage?

According to the ADA, any building used as a place of public accommodation is required to post ADA signage throughout. These include, but are not limited to, office buildings, school campuses, manufacturing plants and warehouses, hotels, restaurants and bars, and municipal buildings.

When Are ADA Signs Required?

Braille/tactile signs are required for:

  • Signs that display the locations of floors, stairwells, and all exit levels
  • Signs posted at every elevator
  • Signs that display the locations of all restrooms
  • Signs posted at every permanent room (such as a conference room, lunch room, storage room, or closet that will not change function for the foreseeable future)

ADA Storage Room Sign

When Are ADA Signs Not Required?

ADA compliant signs are not required for rooms including the following (among others):

  • Rooms that do not serve a permanent function or that are temporary in nature, such as classrooms and individual offices – these rooms can be identified with a simple room number sign
  • Temporary signs (posted for seven days or less)
  • Building directories
  • Building addresses
  • Parking signs
  • Advertising/marketing signs
  • Company logos and names

Keeping ADA Signs Compliant

ADA signage must be kept current and coincide with the latest official ADA regulations. This should be monitored regularly to ensure that your buildings are up-to-date at all times. Please visit the United States Access Board for the most recent updates and current regulations.

What Does ADA Parking Mean?

Based on availability, your parking facility will need to set aside a specified number of accessible parking spaces as found in the PDF found on ADA.gov. Spaces must measure 96 inches wide for cars and 132 inches wide for vans. An accessible parking space must include an Access Aisle adjacent to it that must be at least 60 inches wide and as long as the space itself. Access Aisles must be marked but how they are marked is based on State or local standards.

An accessible parking space must be marked with a sign bearing the International Symbol of Accessibility. Your parking sign does not require braille or tactile lettering, but needs to have a high-contrast between the background and text and symbol. ADA parking signs must be mounted at least 60 inches above the ground measured from the bottom of the sign.
