Frequently Asked Questions (FAQs)

📌 How are the sizes of replacement sign letters measured?
Sign letter sizes refer to the height of the printed character, not the entire panel. For example, a 4" letter is printed on a 5" panel (4on5) to fit standard track systems properly.
📌 What size lettering will fit my space?
Measure your existing sign panel height and the spacing between tracks. Our most popular sizes are 4", 6", 8", and 10" letters, but choosing the right fit depends on your sign’s layout and readability needs. Contact us for guidance!
📌 What is the difference between rigid and flexible sign letters?
Rigid sign letters use a push-up and drop-down method for secure placement. Flexible sign letters bend slightly, allowing you to snap them into place. Refer to the key differences between Flexible and Rigid Sign Letters.
📌 Can I mix rigid and flexible letters on my sign?
No. While both types work with track systems, rigid letters will not work with flex track (texas track). Flex letters will not work with rigid letter track.
📌 Are these letters weatherproof?
Yes! Our high-impact plastic letters are UV-resistant and built to withstand sun, rain, and wind without fading, cracking, or warping.
📌 How many letters will fit on a line?
The number of letters per line depends on your sign panel width and letter size. Smaller letters allow for more characters per line, while larger letters offer better visibility but fewer per row. A letter "I" will be thinner then say a letter "W".
