ADAAG Manual

Raised and Braille Characters on Hoistway Entrances [4.10.5]

Raised and Braille floor designations are required on both jambs, with the centerline 60 inches from the finished floor. Raised characters must be 2 inches high. Braille characters are often located below raised characters, although the location is not specified in ADAAG. Recommendation:Since Braille characters can be difficult to read if placed too close to raised characters, consider a vertical clearance of at least 3/8 inch. Raised borders can confuse tactile reading of raised characters (and Braille) and should be avoided or spaced away from raised text.
