Braille Exit Sign Requirements: A Complete Compliance Guide

At Braille Sign Pros, we work with facility managers, architects, general contractors, and business owners every day who have the same question: what exactly do the rules say about braille exit signs? The short answer is that the Americans with Disabilities Act (ADA) is very specific, and getting it wrong can mean failed inspections, costly re-orders, or worse, a lawsuit. The good news is that once you understand the core requirements, specifying compliant signage becomes straightforward. Below, we break down everything you need to know about braille exit sign requirements so you can order with confidence.

Why Braille Exit Signs Are Required

Illuminated overhead exit signs handle one job: helping sighted occupants locate exits during an emergency. They do nothing for someone who is blind or has low vision. That’s where tactile braille exit signs come in. Mounted at a consistent height next to every exit door, they allow a person to locate the sign by touch, read the raised characters with their fingertips, and confirm the exit through Grade 2 braille.

The ADA Standards for Accessible Design (specifically § 703) require tactile signage at every permanent exit, including exit stairwells, exit passageways, exit discharge doors, and any door leading directly to an exit. This is separate from, and in addition to, the illuminated exit signs required by the International Building Code (IBC) and NFPA 101 Life Safety Code. In other words: you need both. An overhead “EXIT” light does not replace a tactile braille exit sign, and a tactile braille exit sign does not replace the illuminated one.

Mounting Height and Location

Mounting is one of the most frequently botched parts of installation. The ADA is precise:

• Height: The baseline of the lowest tactile character must be a minimum of 48 inches above the finished floor, and the baseline of the highest tactile character must be a maximum of 60 inches above the finished floor.
• Location — single doors: The sign must be installed on the wall on the latch side of the door.
• Location — double doors with one active leaf: The sign goes on the inactive leaf.
• Location — double doors with two active leaves: The sign goes on the wall to the right of the right-hand door.
• Clear floor space: An 18" × 18" area of clear floor space must be provided in front of the sign, centered on the tactile characters, so a person can approach and read it without obstruction.

If a door has a closer and no hold-open device, the sign can be placed on the push side of the door — a small but useful exception for tight corridors.

Character Requirements

Raised (tactile) characters on braille exit signs must meet a specific set of criteria under ADA § 703.2:

• Case: All uppercase.
• Font: Sans serif. Italic, oblique, script, and highly decorative fonts are prohibited.
• Height: Between 5/8 inch and 2 inches, measured by the uppercase letter “I.”
• Depth: Raised a minimum of 1/32 inch above the sign background.
• Stroke thickness: No more than 15% of the character height.
• Character proportion: The width of the uppercase “O” must be 55% to 110% of the height of the uppercase “I.”
• Spacing: Character-to-character spacing must be at least 1/8 inch and no more than 4 times the stroke width; line spacing must be 135% to 170% of character height.

Every braille exit sign we produce at Braille Sign Pros is engineered to meet these specifications straight from the factory, so you don’t have to become a code expert to order correctly.

Braille Requirements

Braille exit signs must use contracted (Grade 2) braille, which is what the ADA has required since 2010. Grade 2 uses contractions rather than spelling every letter, which is how nearly all braille readers actually read.

Specific braille requirements include:

• Dot shape: Domed or rounded, not flat.
• Position: Placed directly below the corresponding tactile text, with a minimum of 3/8 inch of clear space between the braille and any raised characters or borders.
• Capitalization: Braille should only use capital indicators for the first word of sentences, proper nouns, individual letters, initials, and acronyms. Over-capitalizing braille is a common compliance error.
• Arrangement: Braille characters must be arranged horizontally, never vertically.

Finish and Contrast

ADA § 703.5.1 requires that both the characters and the background of a tactile exit sign have a non-glare finish. Glossy signs create reflection issues for people with low vision and are non-compliant.

Contrast is equally important: characters must contrast with their background at a minimum of 70%, either light-on-dark or dark-on-light. Our braille exit signs are offered in a wide range of color combinations that meet this contrast threshold, so you can match your facility’s design palette without sacrificing compliance.

California and Title 24 Considerations

If you operate in California, note that Title 24 layers additional requirements on top of the ADA, including specific tactile exit sign wording (such as “EXIT,” “EXIT ROUTE,” and “EXIT STAIR DOWN”) at particular locations along the egress path. We manufacture a full line of California-compliant braille exit signs and stairwell signs designed to meet Title 24 alongside the federal ADA standards.

Common Mistakes to Avoid

In more than a decade of producing ADA signage, we see the same errors repeatedly:

1. Mounting too high or too low — always measure from the finished floor, not from the door frame.
2. Using the wrong side of the door — the latch side rule matters.
3. Assuming an illuminated sign is enough — it isn’t. You still need a tactile braille exit sign.
4. Skipping stairwell doors — every exit stairwell door on every floor needs one.
5. Ordering glossy signs — the finish must be non-glare.
6. Mixing serif fonts or lowercase letters — the raised text must be sans serif and all caps.

Order ADA-Compliant Braille Exit Signs
