These are 28 complete, paste-ready logo prompts for Nano Banana — Google's Gemini 3 Pro Image model (Nano Banana Pro) and its text-strong sibling Nano Banana 2. Every prompt leads with the silhouette — the shape of the mark described before any color or texture — because a logo has to read as one clean form at small sizes. Each one names a font and weight where there's type, wraps brand names in "quotes" under five words, asks for flat vector on a plain background, and sets an Aspect ratio 1:1. Paste any of them into the Gemini app right now.

Minimalist geometric marks
Five abstract symbols built from simple shapes. Describe the geometry first, keep it monochrome, and only judge color once the silhouette holds up at 32px. Nano Banana Pro reasons about balance, so tell it the mark must be symmetrical or optically centered.
1. Overlapping Triangles Tech Mark
A minimalist logo mark: two overlapping equilateral triangles forming a single interlocked symbol, black on a plain white background, flat vector, solid fills, no gradients or shadows, clean geometric edges, optically centered with generous margins, designed to work at small sizes down to 32px and in one color. No text. Aspect ratio 1:1.Why it works: Leading with the exact shapes and "works at small sizes" forces a strong silhouette instead of a decorative illustration that falls apart on a favicon.
2. Single-Line Continuous Mark
A minimalist logo mark drawn as one continuous unbroken line that loops into an abstract wave shape, uniform stroke weight, black line on a plain white background, flat vector, no fills, no gradients, no shadows, balanced and symmetrical, centered with even margins, reads clearly at small sizes. No text. Aspect ratio 1:1.Best for: Modern, calligraphic tech and studio brands that want a light, elegant mark that still holds shape when scaled down.
3. Negative-Space Arrow Mark
A minimalist logo mark: a solid rounded square with an arrow shape cut out of the center as negative space pointing up-right, black shape on a plain white background, flat vector, solid fill, no gradient, crisp clean edges, optically centered, simple enough to read at 32px and in a single color. No text. Aspect ratio 1:1.Why it works: Negative space asks the model to think about the silhouette and the counter-shape at once — describing both the solid form and the cut-out keeps the mark legible.
4. Golden-Ratio Circle Mark
A minimalist logo mark built from overlapping circles arranged on a golden-ratio grid, forming an abstract crescent symbol, black on a plain white background, flat vector, solid fill, perfectly symmetrical and geometrically precise, no gradients or shadows, centered with clean margins, works in one color at small sizes. No text. Aspect ratio 1:1.Best for: Finance, consulting, and health brands that want a balanced, "designed" feel — Nano Banana Pro reasons about the grid before drawing.
5. Abstract Leaf From Two Curves
A minimalist logo mark: an abstract leaf formed by two mirrored curved shapes meeting at a point, deep green on a plain white background, flat vector, solid fill, no gradient, no shadow, smooth clean edges, symmetrical, optically centered with generous margins, reads clearly at 32px and in one color. No text. Aspect ratio 1:1.Why it works: The shape ("two mirrored curves meeting at a point") is fully defined before the single color, so the green decorates a mark that already works in black.
Monograms & lettermarks
Four initial-based logos. These contain letters, so switch to Nano Banana 2 for reliable text, put the letters in "quotes" near the start, and name the exact typeface and weight you want.
6. Interlocking Monogram "AV"
A monogram logo of the interlocking capital letters "AV", the A and V sharing a stroke to form one balanced symbol, set in a bold geometric sans-serif similar to Futura Bold, black on a plain white background, flat vector, solid fill, no gradient or shadow, optically centered, crisp edges, reads at small sizes. Spell the letters exactly as "AV". Aspect ratio 1:1.Best for: Personal brands and studios. Use Nano Banana 2 and the "spell exactly" line keeps the two letters accurate.
7. Serif Lettermark in a Circle
A lettermark logo: a single capital "R" in an elegant high-contrast serif similar to Didot, centered inside a thin circular ring, black on a plain white background, flat vector, solid fills, no gradient or shadow, symmetrical, generous margins, clean crisp edges, reads at small sizes. Set the letter exactly as "R". Aspect ratio 1:1.Why it works: Naming a real typeface (Didot) and putting the letter in quotes gives Nano Banana 2 a precise target, so the serif comes out sharp rather than approximate.
8. Negative-Space Letter Monogram
A monogram logo: a solid rounded square with the capital letter "M" carved out of it as negative space in a bold grotesque sans-serif similar to Helvetica Bold, black square with white letter cut-out on a plain white background, flat vector, solid fill, no gradient or shadow, optically centered, crisp edges, reads at 32px. Spell the letter exactly as "M". Aspect ratio 1:1.Best for: App-adjacent brands that want a container shape and a letter in one confident mark.
9. Stacked Initials Seal
A lettermark logo: three stacked capital initials "BLK" tightly aligned into a compact square block, set in a bold condensed sans-serif similar to Bebas Neue, black on a plain white background, flat vector, solid fill, no gradient or shadow, perfectly aligned, centered with even margins, crisp edges, reads at small sizes. Spell the letters exactly as "BLK". Aspect ratio 1:1.Why it works: A three-letter ALL-CAPS block sits inside Nano Banana 2's reliable text range, and "tightly aligned into a compact square" defines the silhouette before styling.
Mascot & character logos
Four friendly characters reduced to clean shapes. Keep them flat and geometric — describe the pose and silhouette, hold the color count to two or three, and avoid photographic shading so the mascot still works as a stamp.
10. Geometric Fox Mascot
A mascot logo: a fox head built from clean geometric triangles, front-facing and symmetrical, a bold simple silhouette with sharp pointed ears, two flat colors orange and white with black outlines, flat vector, solid fills, no gradient, no shadow, no photographic detail, plain white background, centered, reads clearly at small sizes and in one color. No text. Aspect ratio 1:1.Best for: Gaming, sports, and startup mascots — the geometric-triangle instruction keeps it a mark, not an illustration.
11. Friendly Owl Character Logo
A mascot logo: a friendly owl reduced to simple rounded shapes, front-facing, symmetrical, big round eyes, a compact bold silhouette, three flat colors teal, cream, and charcoal with clean outlines, flat vector, solid fills, no gradient, no shadow, no photographic detail, plain white background, centered with generous margins, works at small sizes. No text. Aspect ratio 1:1.Why it works: "Reduced to simple rounded shapes" and a fixed three-color palette stop the model from adding feathers and rendering, keeping the owl legible as a small mark.
12. Line-Art Lion Crest Mascot
A mascot logo: a heraldic lion head drawn in clean uniform-weight line art, front-facing, symmetrical, bold confident silhouette, black lines only on a plain white background, flat vector, no fills, no gradient, no shadow, crisp edges, centered, reads at small sizes and in a single color. No text. Aspect ratio 1:1.Best for: Premium, heritage, and academy brands that want a crest-like mascot without heavy detail.
13. Minimal Bear Coffee Mascot
A mascot logo for a coffee brand: a bear head holding a coffee cup, reduced to simple bold shapes, front-facing, symmetrical, a strong compact silhouette, two flat colors warm brown and cream with clean outlines, flat vector, solid fills, no gradient, no shadow, no photographic detail, plain white background, centered, works at small sizes and in one color. No text. Aspect ratio 1:1.Why it works: Adding one prop (the cup) while insisting on "simple bold shapes" tells the story without breaking the clean silhouette a logo needs.
App icons
Four square icons for the home screen. App tiles are viewed tiny, so the shape must be instantly recognizable. Here gradients are allowed — modern OS icons use them — but keep the glyph itself one simple form and set an Aspect ratio 1:1.
14. Rounded-Square App Icon
An app icon: a single bold abstract glyph of a paper plane centered on a rounded-square tile, white glyph on a solid indigo background, flat vector, simple clean shape, no photographic detail, generous padding around the glyph, crisp edges, instantly recognizable at 60px, plain background outside the tile. No text. Aspect ratio 1:1.Best for: Messaging and productivity apps — the "recognizable at 60px" cue keeps the glyph simple enough for a real home screen.
15. Gradient Glyph App Icon
An app icon: a single simple abstract wave glyph centered on a rounded-square tile with a smooth diagonal gradient from purple to pink, white glyph, flat modern style, one clean shape, no photographic detail, generous padding, crisp edges, reads clearly at small sizes, plain background outside the tile. No text. Aspect ratio 1:1.Why it works: The glyph silhouette is defined first and kept to "one clean shape," so the gradient sits behind a mark that would still read in flat color.
16. Single-Letter App Tile
An app icon: a single lowercase letter "n" in a bold rounded geometric sans-serif similar to Poppins Bold, white letter centered on a rounded-square tile with a solid coral background, flat vector, clean crisp edges, generous padding, instantly readable at 60px, plain background outside the tile. Set the letter exactly as "n". Aspect ratio 1:1.Best for: Single-letter brand tiles. Use Nano Banana 2 so the one glyph renders cleanly at small sizes.
17. Duotone Abstract App Icon
An app icon: an abstract mountain-and-sun glyph made of two overlapping shapes, duotone teal and lime, centered on a rounded-square tile with a dark navy background, flat vector, solid fills, no gradient, one simple recognizable form, generous padding, crisp edges, reads at 60px, plain background outside the tile. No text. Aspect ratio 1:1.Why it works: Limiting to a two-shape duotone glyph gives the model a hard cap on complexity, which is exactly what survives at app-icon scale.
Vintage & badge emblems
Four circular emblems with type on a ring. Badges are text-heavy, so use Nano Banana 2, keep each phrase short and in "quotes," and describe the overall circular silhouette before the retro texture.
18. Vintage Coffee Roasters Badge
A vintage circular badge logo: a central coffee bean icon with the text "BROWN STREET" curved along the top of the ring and "ROASTERS" curved along the bottom, set in a bold vintage slab-serif, two colors dark brown and cream, flat vector, solid fills, no gradient, clean crisp edges, symmetrical, plain white background, centered, reads at small sizes. Spell the words exactly as "BROWN STREET" and "ROASTERS". Aspect ratio 1:1.Best for: Cafes, breweries, and craft brands. Short quoted phrases on the ring stay inside Nano Banana 2's reliable text range.
19. Circular Emblem With Banner
A circular emblem logo: a thin double-ring circle with a mountain icon in the center and a ribbon banner across the middle carrying the word "SUMMIT" in a bold condensed sans-serif, two colors forest green and off-white, flat vector, solid fills, no gradient or shadow, symmetrical, crisp edges, plain white background, centered, reads at small sizes. Spell the word exactly as "SUMMIT". Aspect ratio 1:1.Why it works: One short word on the banner ("SUMMIT") is the safest use of text rendering, and the double-ring silhouette is set before the color pair.
20. Retro Mountain Outdoor Patch
A retro outdoor patch logo: a rounded-rectangle badge shape with a stylized pine forest and mountain scene inside, the text "EST. 2026" in a vintage sans-serif at the bottom, muted 1970s palette of burnt orange, mustard, and cream, flat vector, solid fills, no photographic detail, clean crisp edges, plain white background, centered, reads at small sizes. Spell the text exactly as "EST. 2026". Aspect ratio 1:1.Best for: Outdoor, adventure, and apparel brands wanting a patch-style emblem with a tiny date line.
21. Barber Shop Enamel Badge
A vintage circular badge logo for a barber shop: crossed straight razors in the center with the text "SHARP & CO" curved along the top ring and "SINCE 1998" along the bottom, bold vintage serif, two colors black and gold, flat vector, solid fills, no gradient, clean crisp edges, symmetrical, plain white background, centered, reads at small sizes. Spell the text exactly as "SHARP & CO" and "SINCE 1998". Aspect ratio 1:1.Why it works: Splitting the wording into two short quoted arcs, each under five words, keeps every character legible on the ring.
Wordmarks & mockups
The last seven prompts cover pure-type wordmarks and finished logo mockups. Wordmarks live and die on the typography, so always use Nano Banana 2, keep the name in "quotes," and name the font and weight. For mockups, ask for 4K and a real aspect ratio so the flat-lay looks like a photograph. See the text poster prompts for larger type layouts.
22. Bold Sans-Serif Wordmark
A clean wordmark logo of the word "VANTA" in a bold geometric sans-serif similar to Montserrat ExtraBold, tight even letter-spacing, black text on a plain white background, flat vector, solid fill, no gradient or shadow, perfectly aligned baseline, centered with generous margins, crisp edges, reads at small sizes. Spell the word exactly as "VANTA". Aspect ratio 1:1.Best for: Tech and SaaS brands. A five-letter word in a named weight is exactly what Nano Banana 2 renders most reliably.
23. Wordmark With Integrated Icon
A wordmark logo: the word "PULSE" in a bold rounded sans-serif similar to Poppins SemiBold, with the letter "U" replaced by a simple heartbeat-line glyph, black text on a plain white background, flat vector, solid fill, no gradient or shadow, even letter-spacing, centered, crisp edges, reads at small sizes. Spell the word exactly as "PULSE". Aspect ratio 1:1.Why it works: Swapping one letter for a glyph is a classic wordmark move; naming the exact letter and word keeps the rest of the spelling intact.
24. Elegant Serif Fashion Wordmark
A luxury wordmark logo of the word "MAISON" in an elegant high-contrast serif similar to Playfair Display, wide refined letter-spacing, thin uppercase letters, black on a plain white background, flat vector, solid fill, no gradient or shadow, perfectly aligned, centered with generous margins, crisp edges. Spell the word exactly as "MAISON". Aspect ratio 1:1.Best for: Fashion, beauty, and hospitality brands that want a refined, editorial wordmark.
25. Custom Lettering Script Logo
A hand-lettered script wordmark of the word "Bloom" in a flowing elegant signature-style script, smooth connected strokes with a single underline flourish, black on a plain white background, flat vector, solid fill, no gradient or shadow, centered with even margins, crisp clean edges, reads at small sizes. Spell the word exactly as "Bloom". Aspect ratio 1:1.Why it works: A single short word in script is legible for Nano Banana 2; longer script phrases are where character errors creep in, so keep it to one word.
26. Business Card Flat-Lay Mockup
A photorealistic flat-lay mockup of two matte black business cards on a light concrete surface, one card face-up showing a minimalist white wordmark "VANTA" in a bold geometric sans-serif, the other face-down, soft overcast diffusion lighting with gentle shadows, shot from directly above, shallow depth of field, muted neutral palette, plenty of negative space. Spell the word exactly as "VANTA". Aspect ratio 4:5, 4K.Best for: Presenting a wordmark to a client. The overhead flat-lay and "4K" line make it look like real product photography. See the cheat sheet for more lighting language.
27. Storefront Sign Mockup
A photorealistic mockup of a modern minimalist storefront at golden hour, a clean illuminated sign above the entrance showing the wordmark "MAISON" in an elegant serif, warm golden-hour backlighting with long soft shadows, shot on 35mm, shallow depth of field, muted upscale palette, realistic reflections in the glass. Spell the word exactly as "MAISON". Aspect ratio 16:9, 4K.Why it works: Real lens and lighting language ("shot on 35mm," "golden-hour backlighting") turns a logo into a believable branded scene for a pitch deck.
28. Embossed Logo on Packaging
A photorealistic close-up mockup of a kraft-paper product box with a blind-embossed logo mark, a single abstract leaf symbol pressed into the surface, soft raking side light to catch the emboss with subtle shadows, macro 100mm, shallow depth of field, natural neutral palette, clean minimal composition with negative space. No printed text, mark only. Aspect ratio 3:2, 4K.Best for: Showing a symbol mark on real packaging. Raking side light is what makes a blind emboss read — and it proves the silhouette works in one tone.

Frequently Asked Questions
Which Nano Banana model is best for logos?
Use Nano Banana Pro (Google's Gemini 3 Pro Image) when the mark is purely graphic and you want it to reason about balance and geometry before generating. Switch to Nano Banana 2 the moment the logo contains words — it has best-in-class text rendering, so a monogram, wordmark, or badge with a tagline comes out crisp and legible. Both run in the Gemini app and the Gemini API in about two to five seconds.
Why should a logo prompt describe the silhouette before color?
A logo has to read as a single recognizable shape at small sizes — on a favicon, an app tile, or a stitched cap. If you lead with color, gradients, and texture, the model optimizes for a pretty picture instead of a clean mark. Describing the silhouette first — "two overlapping triangles, black on white, flat vector, works at small sizes" — forces a strong, simple form, and you add color once the shape holds up in monochrome.
How do I get readable brand text in a logo?
Wrap the exact words in quotes, keep them under five words (one to four words in ALL-CAPS is the reliable range), name a specific font and weight, and put the text instruction near the start of the prompt. Prefer Nano Banana 2 for anything with type. If a letter comes out wrong, don't regenerate — describe only the fix, such as "keep the layout identical, correct the spelling to VANTA," and it edits in place.
How do I make a flat, vector-style mark instead of a 3D render?
Say it explicitly: "flat vector, solid fills, no gradients, no shadows, no photographic detail, clean geometry, plain white background." Nano Banana still outputs a raster PNG, but this language pushes it toward the crisp, printable look of a true vector logo. Add "works in one color" or "reads at 32px" to keep the shapes simple enough to survive scaling down.
Can Nano Banana give me a transparent background?
Ask for a plain white or plain black background and a centered mark with generous margins, then knock the background out afterward — the flatter and cleaner the background, the easier that is. You can also request "an isolated mark on a neutral background, no scene, no props" so nothing bleeds into the logo. For a genuinely transparent PNG, export from the Gemini app or run the image through a background remover.
Is an AI-generated logo production-ready?
Treat it as a high-quality concept, not a final deliverable. The output is a raster image, so for print, embroidery, and responsive web use you'll want to redraw or auto-trace it into a true vector (SVG) in a tool like Illustrator or a vectorizer. Use Nano Banana to explore directions fast, lock the silhouette and type, then rebuild the winner as clean vector paths.
Every output carries a SynthID watermark — does that affect my logo?
Every Nano Banana image carries an invisible SynthID watermark, and free tiers add a small visible mark. The invisible watermark doesn't affect how the logo looks or prints. If you see a visible mark, generate on a paid tier or, better, use the AI image only as a concept and rebuild the final logo as a clean vector, which removes any embedded mark entirely.
Can I use these logos commercially?
The prompt text is free to use and adapt. Whether the generated image is cleared for commercial and trademark use depends on your Google/Gemini plan and current usage policy, so check the terms tied to your account before shipping a client brand. A safer path for anything trademarked is to use the AI mark as a concept, then commission or redraw a final vector you own outright.
