What size should my exterior signage lettering be?
|Letter Height||Readable Distance for Maximum Impact||Maximum Readable Distance|
Note: The distance will vary approximately 10% with various colour combinations. Maximum distance is in colour RED or BLACK on a WHITE background. 5,280 feet equals one mile.
What if my store faces a roadway?
(Length of time letters are readable when moving)
|Letter Height||30 MPH||40 MPH||60 MPH||80 MPH|
|6″ letters||1.4 seconds||1 second||0.7 seconds||0.5 seconds|
|8″ letters||1.8 seconds||1.4 seconds||0.9 seconds||0.7 seconds|
|12″ letters||3 seconds||2 seconds||1.5 seconds||1 seconds|
|18″ letters||4 seconds||3 seconds||2 seconds||1.5 seconds|
|24″ letters||5.5 seconds||4 seconds||2.75 seconds||2 seconds|
|36″ letters||8 seconds||6 seconds||4 seconds||3 seconds|
Colour selection can dramatically increase readability, especially when at a distance.
How do I calculate board feet?
“Board Feet” Is a measurement of lumber volume. A board foot is equal to 144 cubic inches of wood. You can calculate the board footage using this formula.
(Thickness × Width × Length) / 144 = Board Feet
Note: Lumber is specified by its rough size. This is why a 1” × 4” board is actually 3⁄4” thick and a 2” × 4” board is actually 1 1⁄2” thick.
When you are figuring out board feet, keep in mind a waste factor. If you purchase good clear material add about 15% for waste. If you elect to use lower grade material you will have to allow for defects and more wasted material. Add about 30%.
