ADA Signage Calculator

No. The 48-inch minimum, 60-inch maximum, and 54-inch recommended center are fixed by the ADA Standards for any permanent room, exit, or restroom identification sign and do not change based on sign type, tactile text, or Braille selections in this calculator -- only the estimated sign cost varies with those choices.

Sign Type changes two things at once: a cost multiplier (exit signs carry a higher multiplier than room ID signs) and the default plate size used for the area-based portion of the cost, since exit signs are modeled larger than room ID or restroom signs. Raised text and Braille each add a fixed dollar amount regardless of sign type, so they move the total by less than switching sign type does.

Permanent room identification signs generally require both tactile (raised) characters and Grade 2 Braille under the ADA Standards, which is why this calculator defaults both to Yes -- Section 216.2, read with the technical requirements in 703.2 and 703.3, specifically requires that "the content of raised characters also must be provided in contracted or 'Grade 2' braille" on signs designating permanent rooms and spaces. Some sign categories are treated differently under the standards (for example, certain informational or directional signs that are not identifying a permanent room), so always confirm the specific sign's category against the full standard before assuming a blanket requirement.

The 48-inch minimum and 60-inch maximum define the legal window the ADA Standards allow for centering the tactile characters above the finished floor -- installing outside that window is non-compliant. The 54-inch recommended center is this calculator's own suggestion, sitting at the midpoint of that window so a typical installation has equal margin above and below the two hard limits.

Treat it as a rough planning figure, not a fabricator's quote. It combines a simplified base cost, a size-based area charge, and flat surcharges for tactile text and Braille, but real signage pricing also depends on the specific substrate, mounting hardware, finish, and the fabricator's own rates, all of which vary by vendor and region far more than this model captures.
