What size flag should is appropriate for my flagpole?

The size of flag is dependant on the size of the flagpole. For porch mount flagpoles the 3 x 5 Ft flag is the most common. For in-ground flagpoles the general rule of thumb is that the height of the flag should be 1/5th the height of the flagpole. For example take a 25 ft high pole – 1/5th of the 25 ft leaves 5 ft. So that would carry a 5 x 8 ft flag.

Please be aware of the size of flag that is recommended for your flagpole. Flying a larger flag than is recommended by the manufacturer may result in damage to the flagpole.
