Flag Design Patterns
Flags follow recognizable design patterns that have evolved over centuries. Explore the most common layouts and see which flags use each one.
Horizontal Tricolor
Three equal horizontal bands of different colors, stacked top to bottom. The most common flag design in the world, especially popular in Europe.
The horizontal tricolor gained prominence during the French Revolution and spread throughout Europe in the 19th century as nations adopted it as a symbol of republican ideals and sovereignty.
Vertical Triband
Three equal vertical stripes of different colors, arranged left to right. Distinguished from a tricolor by having the stripes run vertically.
The French Tricolore, adopted during the Revolution, is the most famous vertical triband and inspired many other nations to adopt similar designs throughout the 19th and 20th centuries.
Bicolor
A flag composed of two equal bands, either horizontal or vertical. One of the simplest flag designs, relying entirely on color choice for its identity.
Bicolors are among the oldest flag designs, with some dating back centuries. Their simplicity makes them easily recognizable and reproducible, which was important before standardized manufacturing.
Nordic Cross
A cross that extends to the edges of the flag with the vertical bar shifted toward the hoist side. Shared by all Nordic countries.
The design originates with the Danish Dannebrog, considered the oldest continuously used national flag. Legend dates it to 1219, though documented use begins in the 14th century. Other Nordic nations adopted the cross design to show cultural kinship.
Saltire
A diagonal cross forming an X shape, also known as a Saint Andrew's cross. The arms of the cross extend from corner to corner of the flag.
The saltire is named after Saint Andrew, who was reportedly crucified on an X-shaped cross. Scotland's flag is the most well-known saltire, and it forms part of the United Kingdom's Union Jack.
Examples
Canton with Field
A distinct rectangular area in the upper-hoist corner (canton) on a contrasting background field. The canton typically contains stars, a union flag, or other symbols.
This design has roots in naval ensigns, where the canton identified the nation while the field color indicated the vessel type. The United States flag popularized this design, and many former British colonies retain the Union Jack in the canton.
Single Color with Emblem
A solid-colored field with a central emblem, seal, or charge. The emblem serves as the primary identifier of the flag.
This is one of the oldest flag traditions, deriving from medieval banners that displayed a ruler's coat of arms or a religious symbol on a plain field. Many modern flags continue this tradition with national emblems.
Examples
Chevron
A V-shaped or triangular element at the hoist side that points toward the fly. The triangle typically contrasts with horizontal bands on the rest of the flag.
Chevron designs gained popularity in the 20th century, particularly among newly independent African nations. The triangle often represents the people's forward movement or struggle for independence.
Examples
Horizontal Stripes with Emblem
Horizontal stripes (often a tricolor) with a central emblem, coat of arms, or charge overlaid on the stripes. Combines the simplicity of stripes with a distinctive national symbol.
Many nations add emblems to otherwise simple stripe designs to distinguish their flags from similar-looking neighbors. This is particularly common in Central and South America, where several countries share similar color schemes.
Quarterly
A flag divided into four equal quadrants (quarters), each potentially a different color or bearing a different charge. Also known as a quartered flag.
Quartering originated in heraldry as a way to combine the arms of multiple families or territories into a single shield. It was adopted into flag design for similar purposes of representing united entities.
