Recommended Flag Sizes for Your Flagpole

One of Our Most Popular Questions -

What Is The Correct Size Flag For My Flagpole ?

The length of the your flag should be between one-quarter and one-third the height of the flagpole. Example: using the 1/4 rule, a 20 ft. flagpole would use a 3x5 ft. flag. The two major factors for knowing which flag you should use for your in-ground flagpole is the material of the flag and exposure to wind.

Materials for United States flags are typically Cotton, 1-ply Polyester, 2-ply Polyester, and Nylon.

  • Cotton fabric is for the purest at heart, it is very durable, but fades fast under extreme sun exposure.
  • 1-ply Polyester fills the needs of the budget minded
  • Nylon is the most popular fabric because it is moderately priced, takes a light wind to lift the flag and is fairly durable.
  • If your flag is wearing out every 6 months or less than you are a candidate for a Polyester High Wind flag. Developed by, it is designed high wind areas or extreme outdoor weather conditions.
