Font Height
The letter height you order is based on the uppercase letter "A" of the font you specify.
Depending on the font, some uppercase/lowercase letters may be shorter or taller than the height
you specify on the order form so they will look proportionate to each other. Therefore, you may
receive some of your lettering in different dimensions than the letter height ordered. If all
lettering is ordered in lower case, we still scale the lettering to an uppercase "A" which will
make most of the letters smaller than what was ordered. Please contact us if you would like to
size your lettering differently from our standards. Please see examples below:
Fractions: Order the next size up and indiciate in the comments field the exact height you want your letters.
For example, to order 2 5/8 Inch height, order 3 Inch and write in the comments "Cut at 2 5/8 Inches"
