Determining the size of the Sign Letter

Two measurements are usually referred to in sizing flat plastic letters. 

For example:  8” on 8 7/8” letter. 

1. The first number 8” is the size of the letter printed on the plastic panel.
2. The second number 8 7/8” is the height of the plastic panel.

The second number - the height of the plastic panel is the measurement needed to make sure the letter fits into the sign tracks.

In this example the height of the plastic panel (or back) is 8 7/8 inches. Some manufactures will make and 8” on 9 inch letter. Most signs have their tracking spaced so size both panels, the 8 7/8th inch and the 9 inch panel will fit.

Flat plastic Changeable letters can be catagorized into two types:

1. Flexible Plastic Letters
2. Rigid Letters - Gemini Pronto - Zip Change Letters
