Sign Letters

Outdoor Signs America offers the highest quality sign letters at the best prices! All of our changeable sign letters, numbers, and symbols are made of durable, high-impact acrylic that will withstand exposure to the elements.

Sign letters come in multiple styles.
Please ensure that you select the correct style of letter for your sign.

For OSA Changeable Letter Signs, browse our Changeable Sign Letters category for flexible 0.03” acrylic letters designed to bend into the changeable copy track that holds them in place. Available in 4”, 6” and 8”.

For Stewart™ signs, view our Gemini Sign Letters category for thick, durable sign letters made specifically for this line of signs. These non-flexible acrylic sign letters are strong enough to prevent warping and keep letters in place under most wind conditions. Will NOT work with OSA-brand signs or sidewalk signs.

For Sidewalk Signs, shop our Sidewalk Sign Letters category for flexible letters, symbols, and sign numbers made for black and white sidewalk signs.
