There is not now, nor has there ever been such thing as the 'American' flag. Continents do not have flags. Each country has its own. Should you mean the US flag then see the related question below.

The 43-star United States flag, in use between 1890 and 1891, was arranged with eight stars on the top row, and seven stars on each of the five rows beneath. The first, third, and fifth row of stars are centralized, while the second and fourth row of stars are offset to the right.

The US national flag of red and white stripes with a blue field of white stars has changed many times over the years. It began with a circle of 13 white stars in a blue field, with 13 alternating red and white stripes. As each new state joined the union both the number of stars and the number of stripes increased by one. After there were 15 stars and 15 stripes it was decided to hold the number of stripes to 13, representing the 13 original states, and add one star for each state as it joined the union. Since then there have been flags with increasing number of stars.By the time of World War 2, there were 48 stars in the flag. In 1959 the number went to 49 with the admission of Alaska and in 1960 the number went to 50 with the admission of Hawaii. As of 2015 there are still 50 stars in the US national flag.
