Directional Sign

Signs not required to contain tactile characters must comply with the requirements for visual characters.

• Characters and their backgrounds shall have a non-glare / matte finish.

• Characters shall contrast with their background: either Light characters against a dark background or Dark characters against a light background.

• Characters shall have a stroke thickness which is 10% minimum and 30% maximum of the height of the character, based on the uppercase letter "I".

• Spacing between individual characters, excluding word spaces, shall be 10% minimum and 35% maximum of the character height.

• Characters can be uppercase, lowercase, or a combination of both.

• Type style shall be conventional in form. Characters shall not be italic, oblique, script, highly decorative, or of other unusual forms.

• Character height is based on height above the floor and minimum viewing distance. Character height is based on the uppercase letter "I". Minimum viewing distance is measured as the horizontal distance where an obstruction prevents further approach toward the sign.

Refer to the table on the page, Minimum Character Heights for Visual Signs, for character height recommendations.
