When you plan the room signs for a dental office, there is a rule on the permanent-room signs you can settle yourself with a tape. For a sign that names a permanent room, part of getting it right is a measured placement on the wall, right where a patient reaches for it. Take a tape to a candidate sign, read two lines up to the raised characters, and you know where it stands. These are the signs a patient uses to move through your office, including the ones who read by touch, so getting them right is part of making the office easy to use for the patients who need them most.
The Height You Measure From the Floor
Start with the number a patient touches. Under the 2010 ADA Standards, the raised characters on a permanent-room sign are measured to a baseline that sits in the 48-to-60-inch range above the finished floor. You measure to the baseline of the tactile letters themselves, taken from the finished floor, rather than to the top edge of the panel or its center. The panel's outer dimensions do not set this measurement, because the number is taken from the floor to the characters. Two lines matter here, the lowest line of raised characters and the highest, and both belong inside that range. That is the placement a patient meets when they reach for the sign, so it is confirmed on the wall itself.
Here is the test you can run yourself. Hold a tape to the finished floor and read up to the lowest line of raised characters, then up to the highest line, both taken to the characters themselves. When both numbers fall inside that range, the mounting height is right. Height is one of the requirements a permanent-room sign carries, and it is the one a patient meets by touch, so it is worth confirming on every covered sign before it goes up.
Which Signs the Rule Is Even About
The baseline rule applies to one class of sign, the ones that name a permanent room, so a sign that identifies a restroom or a specific operatory carries the tactile and braille requirements. A sign that shows the way down a hall belongs to a different class, the visual-character class, with its own set of rules. So before you measure, separate the signs that name a permanent room from the ones that only show the way, and take the tape to the ones that name a room.
The Pictogram Field and the Text Below It
Some permanent-room signs include a pictogram, such as the restroom symbol. Where a sign uses one, that pictogram sits in a field at least six inches high. The raised letters and braille go in a band below that field. You read the raised descriptor beneath the pictogram with your fingers, while the pictogram itself is there for the eye. So there are two things to measure on a pictogram sign, the height of the field and the placement of the descriptor below it, and both come off the same tape.
What a Finish Sample Can and Cannot Settle
Finish and color are worth checking on a real sample. A non-glare face and a clear light-on-dark or dark-on-light pairing can contribute to whether the characters stay readable up close. You settle that by looking at a production sample under the light where the sign will hang, since a color name on a screen can seem to have plenty of contrast and still wash out on a glossy face. Finish is one input you can approve early, and you confirm the placement separately, on the wall.
Before you price anything, walk your office door by door and count the permanent rooms, the doors that keep their name from one patient to the next. That count is your candidate list, the signs likely to carry the tactile requirement, and it is the most useful thing to bring to a first call. Bring it to Grand Rapids Sign Company, and we classify each sign and measure its baseline, plus the pictogram field on any sign that uses a symbol. We build each sign and mount it to the number, and we serve Grand Rapids practices from our shop in Walker. Start with the door count and call (616) 284-8739. The right placement is a number you can measure yourself.
