ADA sign mounting height
Tactile signs (room, restroom and exit door signs): the baseline of the lowest tactile character, usually the braille, at least 48 in above the finish floor, and the baseline of the highest raised character no more than 60 in (703.4.1).
Visual-only signs: characters at least 40 in up (703.5.6). Parking signs: at least 60 in to the bottom of the sign (502.6).

|---|---|---|
| Room, office and restroom identification (tactile) | 48–60 in to baselines | 703.4.1 |
| Exit stair, exit passageway and exit discharge doors (tactile) | 48–60 in to baselines | 216.4.1 |
| Elevator hoistway floor designations, both jambs | 48–60 in to baselines | 407.2.3.1 |
| Directional and informational signs (visual only) | 40 in min to baseline | 703.5.6 |
| Parking space identification | 60 in min to bottom | 502.6 |
| Signs hung over a walkway | 80 in min clear below | 307.4 |
| Wall signs with a leading edge 27–80 in up | 4 in max projection | 307.2 |
| Signs on posts, 27–80 in up | 12 in max overhang | 307.3 |
| Elevator car controls | exempt from 48–60 | 703.4.1 |
How to measure it
The measurement runs from the finish floor or ground (the tile or carpet, not the slab) to the baselines of the characters, not to the edges of the sign. Two lines matter: the baseline of the lowest tactile line has to be at or above 48 inches, and the baseline of the highest raised line at or below 60 inches. On most signs the lowest tactile line is the braille, which the Access Board's own guide dimensions as 48 inches minimum to the braille baseline.
The band is 12 inches tall and the tactile block on a typical room sign, two lines of text and a line of braille, is only about 2 inches from top baseline to braille. Room is rarely the problem. Measuring to the wrong point is.
Only tactile content has to sit in the band. On a restroom sign the pictogram field is not tactile, so a 6 inch pictogram can sit above 60 inches as long as the raised text descriptor and braille below it are inside the band.
The old "60 inches to center" rule
The 1991 ADA guidelines put tactile signs 60 inches above the floor to the centerline of the sign. The 2010 Standards replaced that with the 48 to 60 inch range measured to character baselines, and they have applied to new construction and alterations since March 15, 2012. Specs, templates and installers still quote the old number. A sign centered at 60 inches puts its top line above 60, which fails the current rule.
Snap the 48 and 60 inch lines with a laser before drilling, and measure from the finished floor. If the flooring is not down yet, find out what is going on it. Put the braille baseline on the 48 to 50 inch side of the band on proofs; it keeps a two or three line sign well under 60 without any fiddling on site.
Protruding and overhead signs
A sign is also an object people can walk into. Anything on a wall with its leading edge between 27 and 80 inches above the floor can project 4 in at most, because a cane sweeping the floor will not find it (307.2). Flag-mounted and blade signs in corridors usually have to go above 80 inches for that reason. Signs on posts or pylons can overhang a path by 12 in at most in the same zone, and a sign spanning two posts more than 12 inches apart has to have its lowest edge at 27 inches or less, or 80 inches or more (307.3). Anything hung over a walkway needs 80 in of clear headroom (307.4).
Overhead signs are visual only. Their minimum letter height depends on how high they are and how far away they are read from; the character height calculator works it out from Table 703.5.5.
Questions
What is the ADA mounting height for restroom signs?
Restroom identification signs are tactile, so the baseline of the braille goes at least 48 inches above the finish floor and the baseline of the highest raised character no more than 60 inches above it, on the latch side of the door (703.4.1, 703.4.2). The pictogram above the text can sit higher, because only the raised text and the braille have to be inside that band.
Is ADA sign height measured to the center of the sign?
No. That was the 1991 rule, which put tactile signs 60 inches above the floor to the centerline of the sign. The 2010 Standards measure to the baselines of the tactile characters instead: 48 inches minimum to the lowest, 60 inches maximum to the highest. A sign hung the old way can put its top line above 60 inches.
How high do ADA exit signs go?
Tactile signs at exit stairway, exit passageway and exit discharge doors follow the same 48 to 60 inch rule (216.4.1, 703.4.1). Illuminated EXIT signs over doors are set by the fire and building codes, not the ADA tactile rules; if one hangs over a walkway it needs 80 inches of clearance below it (307.4).
How high should an accessible parking sign be?
At least 60 inches from the ground to the bottom of the sign, so a parked car does not hide it (502.6). Some states ask for more: California requires 80 inches to the bottom where the sign is in a circulation path.
Can an ADA sign go on the door itself?
Only on the push side of a door that has a closer and no hold-open device (703.4.2 exception). Everywhere else the sign goes on the wall at the latch side.
