Size Matters for Signage
Undersized signage is invisible. Oversized signage can get rejected by landlords or code. Use this tool to get a realistic starting point.
#
The Rule of Thumb
1 inch of letter height = 10 feet of readable distance.
So a 6-inch letter is readable from about 60 feet away.
#
Adjust for Speed
Walking traffic can read smaller letters. Driving traffic needs larger letters and less copy.
#
Confirm with Code
Most jurisdictions have sign size limits based on building frontage. Check before finalizing.
