# AI Flag Generator

> An AI flag generator designs a flag from a short description: the colours, a symbol and the shape. On Kenerate AI, GPT Image 2.5 Sunburst draws a flat flag in a real flag ratio such as 3:2 or 2:1 for 7.2 credits at 1K (21 at 4K), and can take your team crest or logo as a reference. The best flags follow the North American Vexillological Association's five rules: keep it simple, use meaningful symbols, 2–3 basic colours, no lettering or seals, and be distinctive.

## Steps
1. Open Image Studio — Go to /app/image and pick GPT Image 2.5 Sunburst (or Recraft V4 for a flat, vector-like look). Sign in free for 25 starter credits.
2. Choose the shape — Set the ratio to 3:2 for a classic flag or 2:1 for a long one. Need 3:5 or 10:19? Generate 16:9 or 2:1 and trim, or use Crop & Expand.
3. Describe the flag — Layout (stripes, cross, canton, field), 2–3 named colours, one symbol and what it means — plus “flat design, fills the frame, no pole”.
4. Refine and export — Make four variants, keep the simplest, upscale to 4K or 8K, and trace it to SVG in Inkscape if a printer needs vector artwork.

## In depth

### The five rules of good flag design (NAVA)
Ted Kaye's Good Flag, Bad Flag for the North American Vexillological Association is the guide flag designers quote most. Here is each rule, and how to say it in a prompt:
- Keep it simple — a child should be able to draw it from memory. Prompt: “one symbol, simple shapes, flat design”.
- Use meaningful symbolism — every colour and shape stands for something. Prompt: say what it means (“a silver peak for the mountains, blue for the lake”).
- Use 2 or 3 basic colours that contrast well. Prompt: name them exactly — “only navy, white and gold”.
- No lettering or seals — words and detailed badges vanish at a distance. Prompt: “no text, no letters, no seal”.
- Be distinctive or be related — don't copy another flag, but echo flags you're connected to. Prompt: “in the style of our club colours, not like any national flag”.

### Flag shapes and which ratio to pick
Flags are written height : width. Pick the ratio in the studio before you generate:
- 2:3 — the most common national-flag shape. Generate at 3:2 (GPT Image 2.5 Sunburst, Nano Banana 2.1, or Recraft V4's 1280×832 Photo 3:2 size).
- 1:2 — the long shape of the UK and Canada flags. Generate at 2:1 (GPT Image 2.5 Sunburst, or Recraft V4's 1536×768 Wide 2:1).
- 3:5 — the common 3×5 ft flag. Generate at 16:9 and trim the sides, or at 3:2 and use Crop & Expand to widen it.
- 10:19 — the official US flag shape. Generate at 2:1 and trim about 5% off the width.
- 1:1 — square, like Switzerland and Vatican City. Any model's 1:1 setting.
- Very long pennants and banners (Qatar is 11:28): 21:9 on GPT Image 2.5 or Nano Banana 2.1, then extend with Crop & Expand.

### 14 flag prompt ideas
Start every prompt with “a flat flag design that fills the whole frame, no pole, no folds, no text”, then add one of these:
- Esports team: black field, a single jagged lightning bolt in electric yellow from corner to corner.
- Football supporters' club: three vertical stripes, claret, sky blue, claret, with a small white star in the centre.
- Fantasy mountain kingdom: deep blue field, a stylised silver mountain peak with a single white star above it.
- Desert empire: sand-gold field, a red sun disc with eight straight rays, a thin black border.
- Sea-faring guild: horizontal white and navy waves, a simple gold anchor in the canton.
- Forest elf realm: forest green field, a white leaf in the centre, a narrow gold band along the hoist.
- Space colony: black field, a white ring like a planet's orbit, three small stars in a line.
- Survival game server: dirt brown and grass green halves, a white pickaxe crossed with a sword.
- Family reunion: the family colours in two horizontal bands, a simple oak tree silhouette in the middle.
- Summer camp: orange and teal diagonal split, a white campfire symbol in the upper corner.
- Running club: white field, a bold red chevron pointing right, like movement.
- Fictional island nation: turquoise field, a white Nordic cross, a small yellow sun in the top corner.
- Book club: burgundy field, a gold open book drawn with five lines.
- Wedding or event flag: two partners' favourite colours in a simple split, an intertwined ring symbol in white.

### From AI image to a flag you can fly
A flag on screen and a flag on a pole need different files. The quickest route to a real one:
- Discord, Twitch or a game: a 1K PNG is enough; use Remove BG if you want the flag on a transparent background.
- Printed paper or poster flags: render at 4K, or upscale to 8K with Image Upscaler.
- Fabric flags from a print shop: trace the PNG to vector in Inkscape (Path > Trace Bitmap, multiple scans by colours) or Illustrator, then send an SVG or PDF.
- Check the colours: name a Pantone or hex value to the printer — the screen colour is only a guide.
- Animate it: turn the flat flag into a waving-flag clip with image-to-video.

### What an AI flag generator can't do
It doesn't check whether your design accidentally matches a real flag — search before you print it on merch. It won't reproduce official national flags to exact specification; download those from the government's own specification sheets. And its files are raster images, so large prints need the vector trace above.

## FAQ
Q: How do I make a flag with AI?
A: Open Kenerate's Image Studio, pick GPT Image 2.5 Sunburst and a 3:2 ratio, and describe the layout, colours and symbol: “a flat flag design filling the frame, navy field, a white diagonal stripe from bottom-left to top-right, a gold eight-pointed star in the canton, no text, no pole”. Generate a few variants, keep the simplest, and upscale it for printing.

Q: What are the rules of good flag design?
A: The best-known rules come from Good Flag, Bad Flag, a booklet by Ted Kaye for the North American Vexillological Association (NAVA): keep it simple enough that a child can draw it from memory, use meaningful symbolism, use two or three basic colours, use no lettering or seals, and be distinctive or be related. NAVA notes there are exceptions, but they should be made with care.

Q: What size and ratio should a flag be?
A: Flags are described as height to width. 2:3 is the most common shape for national flags, followed by 1:2 (the UK, Canada) and 3:5. The US flag is officially 10:19 under Executive Order 10834, though most flags sold are 3×5 ft. Switzerland and Vatican City use square flags, Qatar's is 11:28, and Nepal's isn't a rectangle at all. In Kenerate, generate at 3:2 or 2:1 and trim to the exact shape.

Q: Can the AI make a flag for my team, clan or Discord server?
A: Yes — that's what it's best at. Describe what the group stands for and turn it into one symbol and two or three colours. If you already have a team logo or a family crest, attach it as a reference and ask for it in the centre of a simple field, then compare it with the original, since models can redraw a logo slightly.

Q: Can I design a flag for a fantasy kingdom or a fictional country?
A: Yes. Give the nation a short backstory in the prompt — “a mountain kingdom of miners, proud of its silver” — and ask for symbols that follow from it, such as crossed hammers or a silver peak on dark blue. Making a set? Use the same colours and layout for allied houses, the “be related” rule, so the flags look like they belong to one world.

Q: Can I change or remix a real country's flag?
A: For a fictional world, a historical what-if or a fan design, take inspiration — a colour scheme, a cross, a layout — but make it clearly your own. Don't make versions of real national flags meant to mock or demean a country or a people, or ones that copy extremist symbols: Kenerate's terms ban hate speech and violent extremism. Also note that under Article 6ter of the Paris Convention, a country's flag and emblems can't be registered as part of a trademark without permission.

Q: Can I get my flag as an SVG or vector file?
A: Not directly. Kenerate's image models return raster images (PNG or JPG), not SVG. Flags are ideal for tracing, though: with flat colours, Inkscape's Trace Bitmap (multiple scans by colour) or Illustrator's Image Trace turns the PNG into clean vector shapes. Upscale first, keep the design to 2–3 colours, and tidy the paths before sending it to a printer.

Q: Will an AI flag print sharply on fabric?
A: Render at 4K, or upscale with Kenerate's Image Upscaler (up to 8K, 3 credits) — and for large flags, give the printer a traced vector file. Ask the print shop for its file size, colour and bleed requirements before ordering, because fabric printing varies by shop and material.

Q: Is the AI flag generator free?
A: Free to start. A new Kenerate account gets 25 credits on sign-up — three GPT Image 2.5 Sunburst flags at 1K — and Qwen Image 3.0 is a free-plan model. After that, credits come in one-time packs that never expire, with no subscription. Downloads carry no watermark.
