The life of a banner really depends on how it is being used, stored, and taken care of. The more it is being used, the faster it will wear out. Although, typically banners last for anywhere between 3-6 years. The most they can serve you is 5-10 years, or the least 1-2 years. Naturally, if the banner is being used outdoors 24/7, due to the weather conditions and the sunlight, it will wear out more quickly than if used sporadically, or if used indoors.
