Start from a country flag
These presets recreate the simple geometric layout of each flag (colors and proportions are approximate). Click to load:
Flags with detailed coats of arms are not included. Some countries regulate the use of their official national flag and arms; redesigns here are for creative and educational use.
Flag redesign ideas
- Swap the palette to imagine an alternate-history version.
- Change proportions from 2:3 to 1:2 and see how the balance shifts.
- Add a single bold symbol, following the principles of good flag design.
How to redesign a country flag
- Load a preset. Click a country above. The layout, colors and official aspect ratio are loaded into the editor.
- Decide what you are changing and why. An alternate-history version, a regional variant, a sports fan flag or a design exercise each call for different changes.
- Change one element at a time. Swap a color, move the symbol or change the ratio, and compare with Undo/Redo.
- Export. PNG for presentations and posts; SVG to keep refining in a vector editor.
Official aspect ratios of the preset flags
Many people are surprised that national flags are not all the same shape. The presets load each flag's official ratio (height:width):
| Flag | Official ratio | Loaded in editor |
|---|---|---|
| France, Italy, Netherlands, Austria, Ukraine, Japan, Indonesia | 2:3 | 2:3 |
| Germany, Bangladesh | 3:5 | 3:5 |
| Scotland | 3:5 (most common; no single statutory ratio) | 3:5 |
| Ireland, Nigeria | 1:2 | 1:2 |
| Switzerland | 1:1 | 1:1 |
| Sweden | 5:8 | 1:2 (nearest available) |
| Poland | 5:8 | 10:19 (nearest available) |
| Denmark | 28:37 | 2:3 (nearest available) |
| Norway | 8:11 | 2:3 (nearest available) |
| Finland | 11:18 | 2:3 (nearest available) |
Nordic flags use precise proportions for the cross arms (for example Denmark's 3:1:3 hoist and 3:1:4.5 fly). Our Nordic layout uses a close standard geometry, which is accurate enough for school, slides and design practice but not for official reproduction.
Flag families and why so many flags look alike
Many national flags are visually related because they share history:
- Nordic cross – Denmark's Dannebrog (one of the oldest flags still in use) inspired Sweden, Norway, Finland, Iceland and regional flags such as Åland and the Faroe Islands.
- Revolutionary tricolors – the French tricolor inspired many vertical tricolors, including Italy, Ireland, Belgium and Romania.
- Pan-Slavic colors – red, white and blue horizontal bands in Russia, Serbia, Slovakia, Slovenia and others.
- Pan-African colors – green, yellow and red (from Ethiopia) and red, black and green (from the UNIA flag) appear across Africa and the Caribbean.
- Pan-Arab colors – red, white, green and black from the Arab Revolt flag.
Knowing these families helps you design convincing redesigns: a "what if" flag for a country should usually stay inside its family, while a flag for a newly invented country can deliberately borrow one family to suggest a backstory.
Ideas for flag redesign projects
- Alternate history: what would the flag look like if a historical union had survived? Combine two countries' colors with one shared layout.
- Simplification exercise: pick a complex flag (not included here because of its emblem) and redesign it in the spirit of the simple presets using only stripes and one symbol.
- Regional or city flag: use the national colors with a local symbol, such as a mountain, river wave or tree.
- Sports fan flag: national colors in a diagonal or chevron layout with a star.
- Inverted palette: swap the first two colors with the ⇄ button to see how a flag reads with dark and light reversed.
Respectful and legal use
Redesigning flags for art, education, discussion and fiction is common and generally fine. A few things to keep in mind:
- Do not present a redesign as an official flag, or use it to impersonate a government or public body.
- Some countries restrict commercial use of their flag, coat of arms or national symbols (Switzerland's cross, for example, is protected for commercial branding). If you plan to sell merchandise, check the local rules.
- We deliberately leave out flags whose design depends on a detailed coat of arms or seal. Those emblems are often protected and are impossible to reproduce accurately with simple shapes.

Recreating a flag step by step (example: Sweden)
The presets load instantly, but building a flag yourself teaches how the editor works. To build Sweden from scratch: choose the Nordic cross layout, set the ratio to 1:2, set color 1 to blue (#006AA7) and color 2 to yellow (#FECC02). That is the whole flag – two colors and one layout. Now try variations: make the field red and the cross white and you have Denmark; make the field white and the cross blue and you have Finland; pick two colors no Nordic country uses and you have a convincing new member of the family. Building a few real flags this way is the fastest route to understanding why simple flags are so effective.
Using country flags in presentations and reports
For a slide or report, download a 1200px PNG of the preset. Keep flags at the same height in a row so they look tidy, and remember that official ratios differ – Switzerland is square while Ireland is twice as wide as it is tall. If you need many exact national flags with emblems for official documents, use a government or public-domain source; this tool is designed for redesigns, practice and creative work.
