Wayfinding Sign Calculator

Building signage isn't one product — it's several distinct categories each driven by a different piece of the building's layout, and this calculator tallies each one separately before rolling them into a total. Room ID signs equal your room count directly (every permanent room needs one under the ADA Standards' §216.2 signage scoping provision), and when ADA compliance is required, every one of those also needs tactile characters and Grade 2 braille per §703.2-703.4. Directional signs come from corridor intersections (decision points) plus one sign per floor for every two stairways/elevators serving that floor's lobby, while floor directory boards are simply one per floor. Exit signage follows IBC 1013 logic: a sign at every exit door, a sign at every stairway landing on every floor, and a rough estimate of additional corridor exit signs (75% of intersection count) for maintaining exit-sign visibility along travel paths.

Stairway signs double up — floor ID plus re-entry information at every landing on every floor — and restroom signage assumes roughly one restroom per 10 rooms (minimum two), each needing two signs. Overhead/suspended signs are estimated as about 30% of directional signs, reflecting that larger decision points typically get ceiling-mounted rather than wall-mounted signage. Each category carries its own per-unit cost (illuminated exit signs and floor directories cost more than a simple room ID plate), and a 35% installation markup is applied to the combined sign cost for the total project figure. Because the ratios connecting rooms, floors, and stairways to sign counts are industry rules of thumb rather than a code citation for your specific jurisdiction, verify final sign types and placement against your local building and accessibility code before ordering.
