A Guide to ADA-Compliant Fonts for Signage

By |

Table of contents

There are several specifications a sign must meet to be considered ADA compliant. One of the most critical and often misunderstood elements is font. Getting a firm grasp of ADA-compliant fonts for signage can be difficult for those who aren’t as familiar with ADA rules and regulations.

At Erie Custom Signs, we get it. 

That’s why we’ve created a helpful guide that addresses the following:

With this information, sign fabricators and end-users can determine exactly what font case, style, and size are needed on signage. That way, noncompliance issues can be avoided. More importantly, those with visual impairments can easily read ADA signs, which is the ultimate goal.

General Rules for ADA-Compliant Fonts for Signage

In the 2010 ADA Standards for Accessible Design, the ADA outlines various criteria that must be met for compliance, including those related to signage. In fact, the rules for ADA-compliant fonts on signage are very strict. ADA signs are required to use sans (without) serif fonts (fonts that include a smaller line to finish off the main stroke of a letter, as at the top and bottom of “M”). In short, block characters (i.e., letters, numbers, punctuation marks, and typographic symbols) are required by law. 

However, the requirements are even more detailed than that. They also factor in character style, size, case, height, and more.

Here are the general rules for raised characters on identification signage:

Besides limiting the style of characters one can use on ADA-compliant signs, character stroke and spacing are also regulated:

FAQs about ADA-Compliant Font Guidelines

Although there are many rules regarding proper font application with ADA signage, they’re relatively straightforward. Still, it’s not uncommon to have lingering questions about ADA-compliant fonts. To help you out, we’ve addressed a few FAQs below.

1) Is larger font ADA compliant?

The short answer is yes. A larger font is required on all ADA signage to achieve compliance. However, it’s important to highlight that the font size for raised characters should be between 5/8 and 2 inches. 

2) Does all text have to be sans serif?

Under 703.2.3 of the 2010 ADA Standards for Accessible Design, all important text on signage (such as the name of the room being identified by the sign) must be sans serif with no italics or overly decorative lettering. However, if a business desires to add a logo containing a unique font, this is acceptable.

3) Do the above rules apply to all types of ADA signage?

As noted previously, the rules above are specific to raised characters on identification signage. Most of the requirements, including line spacing and proportions, also apply to visual characters on directional and informational signs. But there are some differences. 

Here are some additional guidelines for visual characters:

Note: When visual characters comply with the rules set for raised characters and are accompanied by suitable braille, the above rules don’t need to apply. 

4) Is bolder better when it comes to font?

Actually, no. Most people assume a bold font would help text stand out more. However, choosing one that’s too bold can make the text appear blurry, especially to those with limited vision. That’s why business owners and sign fabricators are cautioned against selecting an overly bold font. 

A good example of a bold font that doesn’t meet ADA guidelines is Bauhaus 93.  

5) What are the consequences of not using an ADA-compliant font?

Though the misuse of font may seem like a minor issue regarding ADA compliance, it can negatively affect a business. By installing a sign that doesn’t have the appropriate font, businesses can be hit with ADA-related lawsuits or fines. That’s why it’s so important to choose a suitable font for ADA signage in the design phase.

Despite providing detailed visual and raised character requirements for signage, the ADA doesn’t explicitly state what fonts are permitted. The only style guideline is that fonts must be sans serif and not italic, oblique, script, highly decorative, or otherwise unusual. However, that’s enough to provide a good idea of what can be considered ADA-approved fonts.  

Sans serif fonts are as plain and straight as possible, increasing the ease of readability.

Examples of recommended fonts for ADA signage that meet the above criteria include the following:

Resources for Finding ADA-Compliant Fonts

That means you will be able to use them on any program that fetches fonts from your computer, from Microsoft Word to Photoshop and InDesign.
