Flag Dimensions Calculator
Flying a flag with precise dimensions is more than a matter of aesthetics—it ensures proportionality, proper display, and compliance with official standards. The Flag Dimensions Calculator is a versatile tool that calculates flag width, height, area, perimeter, diagonal, and aspect ratio based on standard or custom ratios.
Whether you’re designing a U.S. flag, a standard flag, a square flag, or creating a custom flag for your organization or event, this calculator simplifies the process, saving you time and effort.
What Is the Flag Dimensions Calculator?
The Flag Dimensions Calculator allows users to determine all key measurements of a flag from one known dimension (width or height) and the chosen flag ratio. Features include:
- Flag Width and Height: Automatically calculates the missing dimension based on the selected ratio.
- Aspect Ratio: Displays width-to-height ratio for proportional accuracy.
- Flag Area: Determines total surface area in square inches.
- Diagonal Measurement: Calculates the diagonal for precise mounting or design considerations.
- Perimeter: Computes the total edge length for finishing, hems, or framing.
The tool includes popular flag ratios such as:
- U.S. Flag: 1:1.9
- Standard Flag: 2:3
- Square Flag: 1:1
- Custom Ratio: Any width-to-height ratio you choose
