Legibility measures the distinct attributes that letters or characters have from one another. If your sign is well designed, it will be easy to read. Some color combinations of background and font give superb legibility while others do not create adequate contrast. To test your sign's legibility, drive past your business and see if you can read it from a distance. Look at it in both daytime and night. Some signs can be difficult to read due to glares cast from street lights or signs on nearby business establishments.
