The American flag consists of red and white stripes and white stars on a blue rectangle. Its core features include the number of stars and the symbolism of their colors.
1. Stripe and Star Composition: The main body of the flag consists of 13 alternating red and white horizontal stripes, representing the 13 former British colonies at the time of independence in 1776. The blue rectangular area in the upper left corner contains 50 white stars, symbolizing the 50 states of the present-day United States. Since Hawaii joined in 1960, the number of stars has remained at 50, a design that has been used ever since.
2. Color Standards and Proportions: The colors used are navy blue (Pantone 281), crimson (Pantone 193), and pure white, symbolizing loyalty, courage, and freedom, respectively. The flag's aspect ratio is 19:10, with the star area occupying 7/13 of the flag's height. Precise proportions are standardized in the U.S. Code, ensuring uniform dimensions during production.
3. Practical Usage Details: Most everyday flags are made of nylon for increased durability and can be flown in rainy weather without being forcibly taken down. Federal buildings open to the public must fly the national flag daily, while private residences often decorate for holidays such as Independence Day and Memorial Day. The flag's design has been modified 26 times throughout history, with the number of stars changing each time a new state joined the country. The stripes, however, have remained constant at 13 to emphasize the nation's founding principles.
