Explanation: The calculator divides the height by the width to determine the actual ratio, then compares it to the standard 10:19 ratio to verify proper proportions.
Details: Maintaining the correct 10:19 ratio is crucial for preserving the flag's official appearance, ensuring proper display of stars and stripes, and respecting flag etiquette. Incorrect proportions can distort the flag's symbolic elements.
