Character Height Visibility Chart

How big does my LED sign need to be? What size lettering should I have on my sign so that motorists can read the message?

Below is a simple distance chart indicating to use as a guide when purchasing your sign. If the sign is to be read from 100 feet away then the characters should be about 2 inches tall. If the sign will be read from 400 feet away, the characters should be at least 8 inches tall.

While this is a simple rule of thumb, there are other factors that come into play when determining the size of your sign. Is the sign intended for individuals walking or for motorists driving at 35 mph? The lettering for the second situation would have to be much larger than the first or there won't be time to read the sign.
