Vinyl banners are a form of outdoor advertising. Most banners are now digitally printed on large format inkjet printers which are capable of printing a full color outdoor billboard on a single piece of material. The most popular banner sizes are 2’x4′, 3’x6′ and 4’x8′. However, when you want a vinyl banner, your sizes really are limitless, although your printing company may not be. Most companies can print a banner up to 5 ft. high and any number wide because of printer restrictions.
