1. What is the American Flag Size Calculation?

The standard proportions of the American flag are defined by law, with the fly (length) being 1.9 times the hoist (height). This calculator helps determine the proper fly length based on a given hoist measurement.

2. How Does the Calculator Work?

The calculator uses the standard flag proportion formula:

Where:

• \( hoist \) — The height of the flag (units)
• \( fly \) — The length of the flag (units)
• 1.9 — Standard proportion multiplier

Explanation: The U.S. flag code specifies that the official proportions are 1:1.9 (height to length).

3. Importance of Proper Flag Proportions

Details: Maintaining correct flag proportions ensures proper display and respect for the flag according to U.S. Flag Code standards.

4. Using the Calculator

Tips: Enter the desired hoist (height) measurement in any units. The calculator will compute the corresponding fly (length) measurement in the same units.

5. Frequently Asked Questions (FAQ)

Q1: Why is the ratio 1:1.9?
A: This is the standard proportion established by U.S. Flag Code for official government flags.

Q2: Are there exceptions to this ratio?
A: Some ceremonial or decorative flags may use different proportions, but 1:1.9 is standard for official U.S. flags.

Q3: What are common flag sizes?
A: Common hoist sizes range from 1 foot (yielding 1.9 foot fly) to 30 feet or more for large displays.

Q4: Does this apply to all U.S. flags?
A: Yes, this proportion applies to all official U.S. flags regardless of size.

Q5: How precise should measurements be?
A: For most purposes, measurements to the nearest 1/8 inch are sufficient, though official flags may require greater precision.
