*Letter heights are based on ANSI Z535.2 guidelines for
safety signs. Approximate sign size assumes the sign
contains an OSHA Danger header with 3 lines of text.
Messaging and header type will influence letter height,
minimum safe viewing distances, and the resulting sign size.
Not sure?
In general, use 1 inch of text for every 25 feet of viewing
distance - under favorable reading conditions. We can help.
Just call!
