Indoor and outdoor banners are most often printed on 13oz scrim white vinyl or nylon flag material, depending on their intended use. Popular sizes range from 2x5' to 3x10'. Banners can be displayed in a variety of ways, including suction cup hooks, tethers/bungee cords, Banner-Ups, dowels, heavy-duty velcro, retractable or non-retractable displays, or attached to buildings for more long-term use. The majority of banners come standard with grommets in at least the corners. Larger banner grommets tend to be every 2 feet.
