Enter the height of the flagpole into the calculator to determine the recommended flag size for that pole. The calculator provides the width and length of the flag based on standard proportions.
Flag Size Formula
The following formulas are used to calculate the flag size.
FW = PH / 4 FL = PH / 3
Variables:
- FW is the flag width (feet)
- FL is the flag length (feet)
- PH is the flagpole height (feet)
To calculate the flag width, divide the flagpole height by 4. To calculate the flag length, divide the flagpole height by 3. These proportions are based on standard flag sizes for aesthetic and practical display on flagpoles.
What is a Flag Size?
Flag size refers to the dimensions of a flag, typically measured in width (the shorter side) and length (the longer side). The size of a flag is often determined in relation to the height of the flagpole on which it will be flown. Proper flag sizing ensures that the flag is visible and proportionate to the pole, providing an aesthetically pleasing and respectful display.
How to Calculate Flag Size?
The following steps outline how to calculate the Flag Size.
- First, determine the height of the flagpole (PH) in feet.
- Next, use the formula for flag width = FW = PH / 4.
- Then, use the formula for flag length = FL = PH / 3.
- Finally, calculate the Flag Width (FW) and Flag Length (FL) in feet.
- After inserting the variable and calculating the result, check your answer with the calculator above.
