Proper Flag Size:


Size is based upon the height of the flagpole and number of flags going on that pole.

  1. One flag on a pole:
    *for flags mounted on roofs, the width of the flag should be the length of the pole
    *for flags on outrigger poles, the flag should be 3/8 to the length of the pole
  2. Freestanding flagpoles:
    *the width of a standard-sized flag should be 1/4 the height of the flagpole Here’s helpful charts to determine the relationship of the flag size to flagpole height
