ADA REQUIREMENTS FOR SIGNAGE
ADA Requirements refer to the requirements put forth by the American Disabilities Act that detail the way in which structures must me designed, constructed, and outfitted to insure accessibility for people with disabilities.
Applications are based on building use.ˇ Private buildings, such as homes are not required to be built along ADA guidelines.ˇ All commercial facilities are required to be built according to ADA guidelines.ˇ The 'ADA Accessibility Guidelines for Buildings and Facilties' or ADAAG outlines all of the applicable requirements for different types of structures.ˇ There are areas that are exempted from the guidelines, such as areas that are used only by employees as work areas (example: stock room with racks or shelves).
There are a number of general guidelines to be considerate of in respect to signage: including exit signs, stairwell signs, room/floor identification signs, and area of rescue assistance signs.ˇ The requirements are as follows:

4.30.2* Character Proportion.
Letters and numbers on signs shall have a width-to-height ratio between 3:5 and 1:1 and a stroke-width-to-height ratio between 1: 5 and 1:10.
4.30.3 Character Height.
Characters and numbers on signs shall be sized according to the viewing distance from which they are to be read. The minimum height is measured using an upper case X. Lower case characters are permitted.
