American Flag Size Formula:
| From: | To: |
The American flag size calculation determines the proper width of the flag based on its hoist (height). According to official specifications, the width should be 1.9 times the hoist measurement, maintaining the correct 10:19 aspect ratio.
The calculator uses the standard American flag proportion formula:
Where:
Explanation: This calculation ensures the flag maintains the proper 10:19 aspect ratio as specified in official flag guidelines.
Details: Maintaining correct flag proportions is essential for proper display and respect of the American flag. Incorrect sizing can distort the appearance of the stars and stripes and may not comply with official flag etiquette guidelines.
Tips: Enter the desired hoist (height) of the flag in feet. The calculator will automatically compute the appropriate width to maintain the standard 10:19 aspect ratio. All values must be positive numbers.
Q1: Why is the ratio 10:19 for American flags?
A: This specific ratio was established by executive order and ensures proper proportions between the union (blue field with stars) and the stripes.
Q2: Are there different size standards for different flag types?
A: While the 10:19 ratio is standard for most American flags, some specialized flags (like parade flags) may have slightly different proportions.
Q3: What are common American flag sizes?
A: Common sizes include 3'x5', 4'x6', 5'x8', and larger sizes that maintain the 10:19 ratio.
Q4: Does this calculation work for metric measurements?
A: Yes, the same ratio applies regardless of measurement units. Simply use consistent units for both height and width.
Q5: Where can I find official flag specifications?
A: Official specifications are maintained by various government agencies including the Department of Defense and General Services Administration.
