12 x 18 Signs

12 x 18 inches is the usual size for parking signs and most property signs, and it fits one post at eye level. Our 12 x 18 page starts with custom signs you design online in that size and the blank, then lists the stock parking, property and speed signs that come in it. Wide 18 x 12 signs are here too.
