Nano Banana Pro Prompts: 25 Copy-and-Paste Prompts for Infographics, Product Shots and Portraits

Nano Banana Pro costs 18 credits at 1K or 2K and 24 at 4K, so a 25-prompt library is a deliberate spend: each prompt below is written to be judged before you render the next version. Since 1K and 2K cost the same, set 2K and use 4K only when the file has to survive cropping or print.

How Nano Banana Pro reads a long, structured prompt

Write in five parts and stop.

1. Subject and material. What it is and what it is made of. “A brushed-steel water bottle” gives the model a surface to render.
2. Light. Direction and quality. “Large softbox from the upper left” is directable; “good lighting” is not.
3. Framing. Lens and view. “50mm, three-quarter view, subject in the lower third”.
4. Composition constraint. The one thing the layout needs, such as space above for a headline.
5. Output intent. Leave resolution out of the prompt; the selector controls it.

Pro accepts up to 8 reference images and returns PNG by default. It carries a STRICT content label, so real public figures and sensitive subjects are refused. The Nano Banana Pro guide covers the spec table and the image prompt guide covers the craft in more depth.

Five infographic and diagram prompts

State the number of elements and the reading order.

1. Four-step process: “A four-step diagram of a water filter, numbered circles joined left to right by thin arrows, flat vector, navy and cream, 4:5.” Look for four nodes, in order, and no stray arrows.
2. Comparison table: “A two-column comparison of two coffee grinders, five labelled rows, simple icons, muted green and off-white, clean grid, 16:9.” Look for rows that line up and labels inside their cells.
3. Timeline: “A five-milestone product roadmap on one horizontal line, short labels beneath each dot, thin sans-serif, light grey, 21:9.” Look for even spacing and one continuous line.
4. Labelled diagram: “A cutaway illustration of a bicycle helmet with four labelled parts and thin leader lines, neutral grey with orange accents, 1:1.” Look for every leader line landing on the right part.
5. Decision tree: “A three-level decision tree for choosing a running shoe, rounded boxes, yes and no branches, two accent colours, top-down flow, 4:5.” Look for a readable hierarchy and no duplicated branches.

For a guided version that starts from your notes, the infographic maker workflow covers the same job.

Five product and ad shot prompts

Name the surface, light and space reserved for copy.

1. Studio packshot: “A matte black skincare bottle on pale stone, seamless warm grey background, large softbox upper left, 85mm, space above for a headline, 4:5.” Look for a clean label and a contact shadow.
2. Lifestyle in use: “A person in a cream knit holds a ceramic mug at a kitchen window, morning light from the right, 50mm, mug sharp and background soft, 4:5.” Look for natural hands and a product that stays the hero.
3. Flat lay: “An overhead travel kit on oatmeal linen: notebook, pen, sunglasses, leather pouch, loose grid, soft daylight, 1:1.” Look for even spacing and no overlapping objects.
4. Hero with splash: “A citrus soda can on dark blue with a clean water splash frozen behind it, hard rim light, droplets sharp, 100mm, 16:9.” Look for a plausible splash shape.
5. Before and after: “Two side-by-side panels of one wooden table, left worn, right restored, identical angle and light, thin divider, 16:9.” Look for matching perspective between panels.

Five portrait and editorial prompts

Editorial work needs a location, a light and a story in the frame.

1. Magazine portrait: “A ceramicist in her studio, clay on her hands, seated beside a wheel, north window light from the left, 85mm, waist-up, 4:5.” Look for natural hands and believable clutter.
2. Environmental portrait: “A bicycle courier leaning against a brick wall at dusk, warm streetlight from the right, 35mm, full body, 3:4.” Look for consistent colour temperature and a readable silhouette.
3. Black and white editorial: “A close portrait in black and white, single hard key from above, deep shadow under the brow, textured background, 85mm, 1:1.” Look for detail held in highlights and shadows.
4. Clean headshot: “A studio headshot on mid-grey seamless, soft key from the left with a subtle rim, 85mm, shoulders square, 4:5.” Look for even skin tone and no seams.
5. Character sheet: “The same person in three views, front, three-quarter and profile, plain light grey, consistent wardrobe and light, 16:9.” Look for the same face across all three.

If a reference image shows a real person, you need that person’s consent before you upload it, and a synthetic portrait should not be presented as a real employee.

Five edit-with-reference prompts

Give every reference a role, then state what must not change.

1. Background swap: “Use image one as the subject and image two as the background plate. Place the bottle on the counter, match the warm light, keep the label unchanged.” Look for a shadow that agrees with the surface.
2. Colour match: “Grade image one to image two’s palette, warm highlights and cool shadows, keep every object and edge unchanged.” Look for consistent white balance.
3. Product in scene: “Place the sneaker from image one into the street scene in image two, match the overcast light and wet pavement, correct scale and contact shadow.” Look for the shoe resting on the ground.
4. Outfit change: “Change the jacket in image one to the olive colour and fabric of image two, keep the face, pose, hair and background.” Look for folds that follow the original pose.
5. Two-reference composite: “Combine the person from image one with the bicycle from image two, match the light direction, keep both proportions, plain wall behind.” Look for hands and contact points that make sense.

Open the image editor for these and attach the references in the order you name them.

Five text, poster and typography prompts

Quote the exact words and keep the text short. Check every character afterwards.

1. Event poster: “A minimalist jazz poster with JAZZ AT NINE in bold condensed type, date and venue below, deep navy, one warm spotlight, 2:3.” Look for correct spelling and a clear hierarchy.
2. Sale banner: “A wide banner with SPRING SALE in large white sans-serif, 30% OFF beneath, soft green gradient, product cut-out on the right, 21:9.” Look for text clear of the product.
3. Book cover: “A literary paperback cover, title THE LONG FIELD in serif capitals, author name at the bottom, muted landscape, thin border, 2:3.” Look for even margins.
4. Quote card: “A square card with STAY CURIOUS in large centred serif, small attribution below, warm paper texture, generous margins, 1:1.” Look for centred type and even spacing.
5. Menu panel: “A cafe menu with five item names and prices in two aligned columns, chalk-style type on a dark board, thin dividing rules, 4:5.” Look for aligned columns.

For banner proportions from 1:8 to 8:1, Nano Banana 2 is 15 credits a render.

Resolution tiers and the mistakes that waste credits

Setting	Credits	Use it for
1K	18	Only when a smaller file is specifically wanted
2K	18	The default for web, social and most print proofs
4K	24	Print, large format, heavy cropping

Four habits waste credits. Rendering at 1K to save money saves nothing. Asking for 4K in the prompt does nothing; the selector controls output size. Writing three competing composition rules produces a compromise. And exploring a new idea at 4K is expensive when a cheaper model can find the composition first.

Draft the idea on a lower-cost model, then bring the finished prompt to Pro for the final render. A 4K Pro image is 24 credits, and the price for your settings is shown before you generate. Failed generations are refunded, one-time credits never expire, and there is no subscription needed. Full plan options sit on the pricing page.

Frequently asked questions

How much does one Nano Banana Pro image cost?

18 credits at 1K or 2K and 24 at 4K. Editing costs the same as generating at the same resolution.

Why should I default to 2K instead of 1K?

They cost the same 18 credits. Choose 2K unless you specifically want a smaller file, and reserve 4K for print or heavy cropping.

How many reference images can I use?

Up to 8 per job, each with a stated role. Nano Banana 2 accepts up to 14 if you need more inputs.

Can it render text accurately?

It can render short text in a layout, which is why the prompts quote exact words. Check every character afterwards, because one swapped letter ruins a poster.

What should I do with a prompt that keeps failing?

Shorten it to the five parts in the first section and remove competing instructions. The model carries a STRICT label, so requests involving real public figures are refused regardless of wording.

Open image generation, pick Nano Banana Pro, set 2K, and run one prompt from the group closest to your job before building a full set. New accounts start with 10 free credits and no card; one-time credits never expire and there is no subscription needed.
