How to make a meme coin logo with AI that still reads at 32 pixels: prompts, sizes and the checks before launch

Most meme coin logos are made in a minute with an image generator, and most of them fail at the one size that matters. The generator shows a 1,024-pixel image with lovely detail; the buyer sees a 40-pixel circle next to a ticker in a bot alert, where the detail is mud and the subject is unrecognizable. This guide is about producing an AI logo that works where logos are actually seen: the prompt structure, the sizes and formats, the legibility tests and the legal line not to cross. It assumes you already have a name that suggests a picture; if not, how to name a meme coin comes first. For using AI across the whole launch, not just the image, see create a meme coin with AI.

Where a logo is actually seen

• Screener lists and bot alerts: a circle of roughly 24 to 40 pixels next to the ticker. This is the most common view of your logo by a wide margin.
• Chart headers and coin pages: 48 to 96 pixels, often cropped to a circle.
• X avatar and post images: the avatar is small; the post image can be large but is seen in a scrolling feed for about a second.
• Wallet token lists: 32 to 48 pixels, frequently on a dark background.
• Full size: almost never, except by you.

Design for the first line and let the others take care of themselves. A logo that reads at 32 pixels reads everywhere.

The five properties of a logo that reads small

1. One subject. A single character, animal or object. Two subjects become a blob at thumbnail size.
2. Fills the frame. The subject should occupy 70% to 85% of the square. Generators love to add margins and scenery; crop them out.
3. High contrast between subject and background. A dark subject on a light solid background or the reverse. Gradients and busy backgrounds disappear into noise when scaled down.
4. Simple shapes and thick outlines. Flat or cel-shaded styles survive scaling; photorealistic or heavily textured styles do not.
5. No text, or text as a single large letter at most. Any word in the image becomes an illegible smudge at 32 pixels, and the ticker is already shown next to the logo by every tool.

A prompt structure that produces a logo rather than an illustration

Image generators default to pictures: scenes with lighting, depth and context. You want an icon. The prompt has to say so explicitly and repeatedly. A structure that works across the common tools:

• Subject, one clause: 'a grumpy walrus head'.
• Style, named: 'flat vector icon style, thick black outlines, cel shading'.
• Composition: 'centered, facing forward, fills the frame, cropped at the shoulders'.
• Background: 'solid pale yellow background, no scenery, no gradient'.
• Exclusions: 'no text, no letters, no watermark, no border, no extra characters'.
• Format: 'square, 1:1'.

Put together: 'A grumpy walrus head, flat vector icon style, thick black outlines, cel shading, centered, facing forward, filling the frame, solid pale yellow background, no text, no letters, no watermark, no border, square 1:1.' Generate four to eight variants from the same prompt. Change one clause at a time (background color, expression, outline weight) rather than rewriting the whole prompt, so you can tell what each change did. Most tools support a negative prompt or an exclusion list; use it for 'text, letters, watermark, signature, blurry, multiple subjects'.

Sizes, formats and file limits

• Export square. Non-square images are cropped to a square or a circle by almost every tool, usually from the center, and the crop takes a different piece of the image on each platform.
• At least 512 by 512 pixels; 1,024 by 1,024 is better and is the default output size of most generators. Larger is unnecessary and inflates the file.
• PNG for flat colors and outlines, JPG for anything painterly. Avoid transparent backgrounds for the main logo: on a dark wallet list a transparent PNG with a dark subject vanishes. Use a solid background and keep a transparent version separately for banners.
• Keep the file under a few hundred kilobytes. Upload forms on launchpads and screeners commonly reject large files, and a 5 MB logo slows every coin page that shows it. Run the final PNG through a compressor.
• Name the file sensibly and keep the original generation at full size. You will need it for the X header, a banner and any later listing that wants a larger image.

Exact requirements vary by platform and change over time. DexScreener's token profile and the metadata forms on launchpads each state their own limits; check the DexScreener docs and the upload screen of the app you are using before you finalize, rather than assuming.

The three-screen test

1. Thumbnail in a feed. Put the logo in an X post draft and look at the preview on a phone without zooming. Can you tell what it is in one second? If you have to look twice, go back to the generator.
2. Chart header. Paste it into a mock pair header next to a ticker at about 48 pixels, or simply resize the image to 48 by 48 and view it at 100%. Outlines should still be visible; the expression should still read.
3. Dark background. View the logo at 32 pixels on a black or dark gray background. Transparent or dark-edged logos fail here, which is where wallet lists live.

A logo that passes all three at 32 pixels will look fine at every larger size. A logo that fails one will be invisible in exactly the context where new buyers first meet the coin, and no amount of detail at full size compensates.

Consistency across the assets

A launch needs more than the coin image: an X avatar, an X header, a banner for the coin page if the platform supports one, and a few post images. Generate them from the same subject and style so the coin is recognizable at a glance in each place. The practical method is to keep the exact prompt and the seed or reference image from the chosen logo, then change only the composition clause ('wide banner, subject on the left, empty space on the right for text') for each asset. Mixing styles across assets makes the coin look like three different projects, and in a feed of copycats, looking consistent is a trust signal. The X header and post images are used in the announcement; how to announce a coin launch on X covers what goes in them.

What not to generate

• Copyrighted characters, even restyled. A generator will happily draw a famous cartoon in a new style; screeners and X will happily remove the coin's profile when the rights holder asks. Use a type of character, not a specific one.
• Real people. The same removal risk, plus platform rules about likeness.
• Existing meme coin logos, lightly modified. The crowd notices, and 'copycat' is the single worst label a new coin can get in its first hour; why most meme coins die in the first hour shows how fast that label spreads.
• Text-heavy designs. A generator asked for text produces misspellings, and even correct text is unreadable at logo sizes.
• Photorealism. It scales badly and reads as an advertisement rather than a meme.

How the logo is used at launch

On sasa the image is uploaded once on the Create page with the name and ticker, and it appears on the coin page, in Explore and in the race view on all four chains from the first second. Screeners and bots that pick the coin up from the DEX pool pull the image from the coin's metadata or from a profile the creator submits, so have the final PNG ready before launch rather than after; a coin that appears in bot feeds with a blank avatar for its first ten minutes has lost the window it needed most. The rest of the pre-launch sequence is in the meme coin launch checklist.
