We hope you find the following charts useful in determining the proper number of raised characters and Braille that fit on an ADA compliant sign. The first chart tells you how many raised characters of a given size fit on one line of a sign at a given width. The second chart tells you how many lines of characters at a given size will fit on a sign of a given height. By using both charts you can determine the proper size sign for almost any interior ADA compliant sign. For example a 4" x 8" with .625" lettering will allow for two lines with 11 characters per line. We hope you find this chart especially useful in the PLANNING phase of a project by allowing you to design the proper sized sign for the information you need on the signs in your building.

The information presented in these charts is specific to signs using raised tactile letters and grade 2 Braille. All data is based on use of the Helvetica font. Consideration has been made to reflect ADA, ADAAG, ANSI and UBC regulations regarding character height, line spacing, kerning (character spacing) and free space around characters. Additional consideration has been given to the probable number of lines of Braille needed given the number of characters on each sign.
