Line Width Guidelines
To ensure maximum visibility/awareness,
the required minimum width required
for facility aisle and floor marking lines is
2” wide- therefore, any width above that
is considered acceptable by OSHA and
ANSI.

2”

3”

4”

6”

Most typical applications use tape or painted lines with 2” - 6” widths.
Widths above 6” tend to be much more cost-prohibitive and impractical to apply.

Aisle Width Guidelines
“Sufficient safe clearances” must be provided
where mechanical equipment is used. The width
required will vary depending upon how the aisle
is utilized in the workplace - Aisles that utilize
forklift and truck traffic will need to be wider
than aisles for pedestrian traffic. A good average
aisle width is 36 inches.
Storage rooms containing flammable and
combustible liquids must have aisles at least 36
inches.
Additionally, for emergency exit access points,
28 inches is the minimum allowed width.
