About: List of national flags by design

A national flag is a flag that represents and symbolizes a country. Flags come in many shapes and designs, which often represent something about the country or people that the flag represents. Common design elements of flags include shapes such as stars, stripes, and crosses, layout elements such as including a canton (a rectangle with a distinct design, such as another national flag), and the overall shape of a flag, such as the aspect ratio of a rectangular flag (whether the flag is square or rectangle, and how wide it is) or the choice of a non-rectangular flag. Sometimes these flags are used to represent languages.
