Vexillography is the art and practice of designing flags; it is allied with vexillology, the scholarly study of flags, but is not synonymous with that discipline.[1] A person who designs flags is a vexillographer.

Principles of flag design

Flag designs exhibit a number of regularities, arising from a variety of practical concerns, historical circumstances, and cultural prescriptions that have shaped and continue to shape their evolution.

Vexillographers face the necessity for the design to be manufactured (and often mass-produced) into or onto a piece of cloth, which will subsequently be hoisted aloft in the outdoors to represent an organization, individual, idea, or group. In this respect, flag design departs considerably from logo design: logos are predominantly still images suitable for reading off a page, screen, or billboard; while flags are alternately draped and fluttering images - visible from a variety of distances and angles (including the reverse). The prevalence of simple bold colors and shapes in flag design attests to these practical issues.

Flag design has a history, and new designs often refer back to previous designs, effectively quoting, elaborating, or commenting upon them. Families of current flags may derive from a few common ancestors - as in the cases of the Pan-African colours, the Pan-Arab colors, the Pan-Slavic colors, the Nordic Cross flag and the Ottoman flag.

Certain cultures prescribe the proper design of their own flags, through heraldic or other authoritative systems. Prescription may be based on religious principles: see, for example, Islamic flags. Vexillographers have begun to articulate design principles, such as those jointly published by the North American Vexillological Association and the Flag Institute in their Guiding Principles of Flag Design,[2] which provides the following basic principles:

  1. "When designing a flag remember that it will fly in the wind and is not just a rectangular design on paper - so think what the flag will look like when flying in a brisk breeze and when hanging down on a still day."
  2. "Simplicity is important in creating a design that is easy to recognize and simple to reproduce. Try re-drawing the design freehand to see whether an imperfect drawing of the flag can still be easily identified. Also try imagining it at a small size, such as a lapel pin, or when viewed from a distance, when small details will not be obvious."
  3. "A flag needs to be distinctive to stop it being mistaken for another. Compare it to neighboring and similar flags to check that they are not easily confused."
  4. "If you want a flag to remain popular for a long time, it should look as “timeless” as possible, to make it immune to changing fashions. Avoid using features in the design that will cause the flag to become dated or obsolete, e.g., a reference to farming could be timeless but depicting a particular style of tractor will date very quickly. Imagine the flag in a historic setting and in a very modern setting to check whether it would work in both."
