🚩 Flag Maker: Design a Custom Flag and Download the SVG

What is the Flag Maker?

A flag is one of the simplest yet most recognizable pieces of design: a rectangle divided into colored areas, sometimes with a symbol placed on top. Most national and regional flags follow a handful of repeating patterns, so a good flag maker only needs a few layout presets to cover the vast majority of designs. This tool builds each layout from plain SVG rectangles, then layers an optional emblem above them, which keeps the output small, sharp at any size, and easy to edit by hand later.

The layouts here map directly to real flag families. Three horizontal stripes (like Germany or the Netherlands) and three vertical stripes (like France or Italy) are the classic tricolors. Two horizontal stripes cover bicolor flags such as Indonesia or Poland. A solid field is the starting point for designs that rely entirely on a central emblem. The horizontal with canton layout places a smaller rectangle in the upper hoist corner, the pattern used by the United States, Liberia and many others, which is one of the most common ways to combine stripes with a distinct corner block.

The optional emblem is drawn as either a five point star or a circle, centered on the flag. The star is a true ten vertex polygon built from an outer and inner radius, the same geometry used on countless real flags, while the circle is a single SVG element. Because both sit on top of the bands, you can recolor them independently to create strong contrast, for example a gold star on a red field or a white disc on a blue ground.

Working in SVG is the key advantage of this flag maker. Unlike a flat PNG, an SVG stores the flag as shapes and colors rather than pixels, so it stays perfectly crisp whether you use it as a tiny favicon or blow it up to poster size. The downloaded file is human readable text you can open in any code or vector editor, tweak the hex values, or paste straight into a web page. The fixed 3:2 aspect ratio (a 300 by 200 viewBox) matches one of the most widely used flag proportions, so your design looks balanced out of the box.

Good flag design is not just about the tool, it is about restraint. The North American Vexillological Association sets out five widely cited principles in its guide Good Flag, Bad Flag: keep it simple enough that a child can draw it from memory, use meaningful symbolism, use two or three basic contrasting colors, avoid lettering and seals, and make it distinctive or related to what it represents. This flag maker is built around those rules on purpose. It gives you bold layouts and a single clean emblem rather than clip art and text, which nudges you toward a design that actually reads well from a distance and in a stiff breeze.

Once you are happy with the design, use it as a starting point rather than a finish line. Sketch the concept for a game faction, a fictional country, a club or a team here, download the SVG, then refine curves, add a coat of arms, or split colors into gradients in a dedicated vector editor. Because the flag maker exports standard SVG markup, every popular editor and browser opens it without conversion, so nothing about your design gets locked into this tool.

When to use it

• Sketching a flag concept for a game, fictional country, club or team before refining it in a full design tool.
• Creating a quick tricolor or bicolor graphic for a presentation, poster or social post without opening heavy software.
• Teaching vexillology or geometry: showing how stripes, cantons and star polygons combine into recognizable flags.
• Generating a lightweight, scalable SVG flag to embed on a website where a crisp icon at any size matters.
• Prototyping a worldbuilding or tabletop campaign with a consistent set of faction flags exported as clean SVG files.
• Testing color and contrast choices against good flag design principles before committing to a printed or sewn flag.

How to use the Flag Maker

1. Pick a layout from the dropdown: horizontal or vertical tricolor, two stripes, solid, or field with a canton.
2. Set a color for each visible band using the color pickers; only the bands your layout uses are shown.
3. Optionally choose a star or circle emblem and pick its color to add a centered symbol with strong contrast.
4. Check the live preview, then click Download SVG to save the flag, or Copy SVG code to paste the markup directly into your project.

Five principles of good flag design (NAVA)

Common mistakes to avoid

• Picking colors with too little contrast. An emblem only reads clearly when it stands apart from the band behind it. A yellow star on a white stripe nearly disappears. Put light emblems on dark fields and dark emblems on light fields so the symbol stays visible at small sizes.
• Forgetting the aspect ratio when resizing. This flag maker exports a 3:2 flag. If you later stretch it to a different ratio in another program without locking the proportions, stripes and the star will distort. Scale the SVG uniformly to keep the shapes correct.
• Expecting a PNG instead of an SVG. The download is an SVG, a vector text file, not a flat image. That is what keeps it crisp at any size, but if a platform only accepts PNG or JPG you will need to open the SVG in an editor or browser and export a raster copy.
• Overloading a simple flag with detail. Good flag design favors a few bold colors and at most one clear symbol. Trying to force complex artwork into this maker leads to a muddy result. Use it for the strong, simple base and add fine detail later in a dedicated vector tool.
• Using too many colors. The NAVA guidelines suggest two or three basic colors. Five or six competing colors muddy the design and print poorly. Choose a small palette with clear contrast and let the layout do the work.
• Copying a real protected flag. Recreating a national flag or a trademarked emblem for commercial use can cause legal and cultural problems. Use real flags as inspiration, but change the layout, colors or emblem enough to make an original design of your own.

Glossary
