The size of flag that best suits your needs depends on how you are going to use the flag. If you plan to have your flag attached to a bracket of the size of your home, we would recommend a 3'x5' flag. Usually this would be attached to our 6' Anti-Furl flagpole so that you never have to worry about the flag wrapping around the pole. If you have an in ground flagpole the typical size for would be either 3' x 5' or 4' x 6' depending on your personal preference. For those of you who have a small commercial flagpole ranging from 30'-45' the recommended flag size would be no larger than a 8' x 12'. The key to determining your size of flag depends on the height of the pole as well as the wall thickness; the thinner the wall thickness the smaller choice of flag should be used in order from preventing the pole to be top heavy. If you are every unsure of the size of flag that would look best on your pole do not hesitate to call us.
