The Rules of Good Flag Design

Vexillology, the study of flags, has developed clear principles about what makes a flag effective. The North American Vexillological Association (NAVA) established five fundamental rules that every good design should follow.

1. Keep It Simple

A flag should be so simple that a child can draw it from memory. The most iconic designs are extremely simple yet immediately recognizable.

Good examples:

Flag of Japan Japan
Flag of Switzerland Switzerland
Flag of Bangladesh Bangladesh

Bad examples: Many US state flags that put complex seals on blue backgrounds.

Flag of Montana Montana
Flag of Minnesota Minnesota
Flag of Kansas Kansas

2. Use Meaningful Symbolism

Colors and symbols should relate to what they represent.

Flag of Israel Israel
Flag of Pakistan Pakistan
Flag of Brazil Brazil

3. Use 2 or 3 Basic Colors

Limit the palette to colors that contrast well.

Flag of Germany Germany
Flag of France France
Flag of Italy Italy

Notable exception: South Africa uses six colors but remains distinctive.

4. No Lettering or Seals

Flags should be recognizable from a distance and in motion.

Flag of Saudi Arabia Saudi Arabia

5. Be Distinctive or Related

A flag should be unique or deliberately related to others.

Distinctive flags:

Flag of Nepal Nepal
Flag of Canada Canada
Flag of Kenya Kenya

Nordic Cross family:

Flag of Denmark Denmark
Flag of Norway Norway
Flag of Sweden Sweden
Flag of Finland Finland
Flag of Iceland Iceland

Bad example: Chad and Romania are nearly identical.

Flag of Romania Romania
