Exit sign requirements specify letter size and maximum distance to exit access?

• A. 6 inches; no more than 150 feet
• B. 8 inches; no more than 200 feet
• C. 6 inches; no more than 100 feet
• D. 4 inches; no more than 150 feet

Answer: (C)

Exit signs are there to keep you oriented and help you reach an exit quickly during an emergency. The design relies on two measurable requirements: the letters must be large enough to read at a glance, and the path to an exit must not be so long that you can’t find a sign in time. The minimum letter height specified is six inches, which provides legibility from typical viewing distances in a hurry. The rule also limits how far you can travel along the path before you encounter an exit sign, set at no more than one hundred feet. Together, these requirements ensure signs are readable and you’re never more than 100 feet from an exit sign while moving toward safety.
