What’s a Good Letter Size?

When making a sign, one main aspect to consider is how big to make it to be effective. The bigger the sign, the more likely it will be seen. But the amount of information you put on it will determine if it can be read easily.

For larger signs such as banners, 3D lettering or store front signage, you need to consider how far people will be viewing it from. Below is an easy guideline to follow to know if your lettering will be visible.

4″ Lettering – Readable from 150 feet
6″ Lettering – Readable from 200 feet
8″ Lettering – Readable from 350 feet
10″ Lettering – Readable from 450 feet
12″ Lettering – Readable from 525 feet
