How to Choose the Font for Your Sign or Banner

Even though it is often an overlooked aspect of signage, letter sizing is one of the most important features that you need to consider when designing a sign or banner. Letter size, which is also called letter height, is what will determine the visibility of your sign, which is how far away your message can be read. In addition to that, the lettering will also affect the quality of the sign, so it is imperative to know the perfect letter height for a specific distance.

Here are some of the aspects of letters that you should pay attention to:

1. Font size

Before you choose the font size for your sign, you should have a general idea of the distance that you want your sign to be visible from. For best results, it is advisable to increase the letter height by at least 1 inch for every 10 feet of viewing. Here is a chart for your better understanding:

Letter Height
Distance For

Best Impact (feet)


Readable Distance


3″ 30’ 100’
4″ 40’ 150’
5″ 50’ 200’
6″ 60’ 250’
7″ 70’ 300’
8″ 80’ 350’

2. Font color

One of the best ways to improve legibility is to use a high color contrast factor. The general rule of thumb here is that you must use a dark colored background with a light colored font and vice versa. Here is some of the common color combinations used in signs:

a) Black font on yellow background
b) Black font on white background
c) Blue font on white background
d) White font on red background
e) Blue font on yellow background
f) Yellow font on black background

3. Font type

Two of the most common font types used for signs are Serif and Sans Serif as they are clear and well-structured. When the font is too decorative or in the form of script, it becomes difficult to read when used with a smaller font size. If you wish to use such fonts then you need to ensure that the letter height is adjusted for ideal visibility.

Adopting these practices for your signs will ensure that they are effective in communicating your intended message. Get in touch with us for sign installation in Florida.
