Larger banners are typically used for outdoor events and spaces, such as tradeshows or kiosks where it’s important to draw attention and gather a crowd. These larger banners can be around 4 ft x 6 ft in size, and are great for communicating special offers or sales to potential customers.
Another common banner size is 3 ft x 6 ft, which is great for printed banners that will be displayed in places such as restaurants or offices. These smaller banners can be used to announce a new service, promote an employee birthday or a company debut party, or even simply to share a fun slogan that you want seared into the minds of your audience.
In addition to banner sizing, there are also some specific factors to consider when it comes to print and digital media. Things such as the publishing platform and the user device can also influence the best banner dimensions to use for a given campaign. This is especially true for web banners, as some sizes are better suited to mobile viewing than others.
