Banner Flags feature a rectangular shape that requires a horizontal support at the top to display the flag properly. An additional few seconds of setup time are required, but that’s about it. Banners flags will flutter more in the wind than either Teardrops or Blades, but the horizontal support ensures good copy visibility in most conditions. Why choose a banner flag over the other two options? Again, that’s mostly a matter of personal preference. Everyone has they’re favorite. That said, your designer might prefer banner flags simply because they’re so easy to work with visually.
