Flag Size Guide

For home wall-mounted flagpoles

5' poles

2' x 3', 2-½' x 4', 3' x 5'

6' poles

3' x 5'

For in-ground flagpoles

The rule of thumb is that the fly of the flag (the length or long dimension) should be 1/3 to ¼ the height of the flagpole. For example, if you have a 20' flagpole, ¼ of that is 5, so the fly of the flag should be 5'. This means that you need a 3' x 5' flag!
