Signs 11
Function:
There are two different types of signage. One is the accessibility indicator informing a
person if a facility is accessible to the disabled. The second is informative and
illustrative. The international symbol of accessibility should be used as an integral part
of the facility.
Requirements:
Letters and numbers on signs shall have a width-to-height ratio between 3:5 and 1:1
and a spacing width-to-height ratio between 1:5 and 1:10. Characters and symbols
shall contrast with their background eight light characters on a dark background or
dark characters on a light background. Consider when placing signs the height of a
person seated in a wheelchair so that they can easily see the signs but not obstruct
their view of danger areas or facilities. Also consider the placement of signs along
walks so that nonsighted persons will not walk into them.
