20 Nano Banana Text Rendering Prompts for 2026

Copy 20 Nano Banana text rendering prompts for posters, signs, labels, and multilingual graphics, with model choices and exact-text checks.

Nano Banana can place words inside an image, but a prompt that merely says “add some text” leaves spelling, hierarchy, line breaks, placement, contrast, and unwanted filler copy unresolved. A better text-rendering prompt behaves like a small production brief.

Use this structure:

FORMAT: [poster, sign, label, cover, social graphic, or diagram].
EXACT TEXT: Render only these quoted strings: "[line 1]" / "[line 2]" / "[line 3]".
HIERARCHY: [which line is primary, secondary, and supporting].
TYPE: [font category, weight, case, color, spacing].
PLACEMENT: [position, alignment, margins, negative space].
VISUAL: [subject, background, palette, material, lighting].
CONSTRAINTS: Preserve spelling, punctuation, capitalization, line order, and language. No extra words, duplicated letters, placeholder copy, logo, badge, watermark, or decorative microtext.

Every template below is free to copy. The free Nano Banana prompt generator also has a Design with readable text preset that builds this structure locally in your browser. It requires no account, image upload, AI call, or credits. Image generation is paid, and the editor shows the model and credit cost before a run.

These are starting templates, not a promise of perfect spelling or layout. Always inspect the rendered image at full size before publishing it.

Quick selector

If you need	Start with	Main failure to inspect
One short word or phrase	Prompt 1	substituted or repeated letters
Event poster or flyer	Prompt 4	wrong date, time, or line order
Sale graphic with numbers	Prompt 5	`0/O`, `%`, decimal, or currency errors
Storefront or physical sign	Prompt 7	implausible mounting and reflections
Product label or packaging	Prompt 9	invented claims and distorted brand text
Cover artwork	Prompt 11	title hierarchy and author-name spelling
Multilingual text	Prompt 14	wrong script, translation, or mixed languages
Existing-image text correction	Prompt 17	unrelated visual changes
Long body copy	Prompt 20	rasterized text that cannot be edited reliably

Choose the model before writing the prompt

Google’s current image documentation describes Nano Banana 2 as the general-purpose model with reliable text rendering and Nano Banana Pro as the premium option for more complex creative control and localization. Google’s own prompting guide recommends quoting exact words and specifying the type style; the Gemini API image guide is the more current source for model availability and capabilities.

For this site’s paid editor:

Job	Practical starting point	Current cost
One short headline, simple sign, or visual concept	Nano Banana 2 at 2K	12 credits
Several exact strings, mixed scripts, dense hierarchy, or precision-critical layout	Nano Banana Pro at 2K	16 credits
Final 4K export after the wording and composition are stable	Nano Banana 2 or Pro at 4K	18 or 32 credits

Do not start at 4K to fix a spelling problem. Resolution adds pixels; it does not turn incorrect wording into correct wording. Validate a cheaper 2K draft first.

Short text and typographic art

1. One-word typographic poster

FORMAT: Minimal 4:5 typographic poster.
EXACT TEXT: Render only the word "FOCUS" in uppercase.
HIERARCHY: "FOCUS" is the only text and fills the central two-thirds of the frame.
TYPE: Heavy geometric sans-serif, white letterforms, tight but even kerning.
PLACEMENT: Centered horizontally and vertically with generous outer margins.
VISUAL: Solid cobalt-blue background with a subtle uncoated-paper texture.
CONSTRAINTS: Spell FOCUS exactly once. No subtitle, logo, symbols, border, watermark, or decorative microtext.

This is the lowest-complexity text test: one word, one type treatment, one location, and high contrast.

2. Stacked motivational phrase

FORMAT: Clean vertical office-art poster, 4:5.
EXACT TEXT: Render these three lines in this order: "DREAM" / "PLAN" / "DO".
HIERARCHY: DREAM is largest, PLAN is medium, and DO is smallest but still prominent.
TYPE: Bold condensed sans-serif in deep charcoal, uppercase, consistent baseline and line spacing.
PLACEMENT: Three centered lines stacked vertically with ample breathing room.
VISUAL: Warm cream background with one thin coral rule beneath the final line.
CONSTRAINTS: Use only the three supplied words. No repeated word, quotation marks, icon, logo, footer, or filler text.

3. Neon phrase as a physical object

FORMAT: Photorealistic neon wall-sign image, 4:5.
EXACT TEXT: The sign reads exactly "STAY CURIOUS".
HIERARCHY: One continuous phrase with equal visual weight.
TYPE: Hand-bent uppercase neon tubing, warm amber light, clearly separated letterforms.
PLACEMENT: Mounted at eye level on the center of a dark charcoal brick wall.
VISUAL: Night interior, visible mounting clips and power cable, restrained bloom, believable amber reflection on nearby bricks.
CONSTRAINTS: No second sign, missing tube segment, extra letter, poster, logo, person, or watermark.

The material and surface matter here: the words are not merely an overlay; they are an illuminated object that should affect the environment.

4. Three-line event poster

FORMAT: Vertical independent-music event poster, 4:5.
EXACT TEXT: Render only these lines: "AFTER DARK" / "FRIDAY 18 OCTOBER" / "DOORS 7 PM".
HIERARCHY: AFTER DARK is the dominant headline. The date is secondary. The door time is the smallest line.
TYPE: Condensed cream sans-serif, uppercase, crisp edges, restrained tracking.
PLACEMENT: Headline in the upper third, date and time aligned at the lower left, safe margins on every side.
VISUAL: Grainy midnight-blue photograph of an empty stage with one narrow overhead spotlight.
CONSTRAINTS: Preserve every letter, number, space, date, capitalization, and line order. No venue, price, sponsor, badge, logo, QR code, or microtext.

5. Sale graphic with numbers and a percent sign

FORMAT: Vertical 9:16 social story.
EXACT TEXT: Render only "WEEKEND SALE" and "50% OFF".
HIERARCHY: 50% OFF is the largest element. WEEKEND SALE sits directly above it.
TYPE: Bold modern sans-serif, white, uppercase, tabular-looking numerals, clear percent sign.
PLACEMENT: Centered in the middle half of the frame with strong spacing between the two lines.
VISUAL: Magenta-to-orange gradient with restrained translucent geometric shapes around the edges.
CONSTRAINTS: The number must be 50, not SO or 5O. No price, currency, terms, button, logo, product, extra percentage, or watermark.

Numbers deserve their own inspection pass. Check 0 versus O, decimal points, currency symbols, dates, phone numbers, and percentages independently from the artwork.

6. Coffee shop promotion with reserved text space

FORMAT: Vertical 2:3 coffee shop poster.
EXACT TEXT: Render "MORNING POUR" as the headline and "7–10 AM" as the supporting line.
HIERARCHY: MORNING POUR is large; 7–10 AM is smaller and clearly subordinate.
TYPE: Warm-white rustic serif headline with a simple sans-serif time line.
PLACEMENT: Both lines sit in clean negative space in the upper third and never overlap the cup or steam.
VISUAL: Close-up of latte art on a walnut table, soft side window light, warm brown and cream palette.
CONSTRAINTS: Preserve the en dash and AM. No menu items, price, address, logo, badge, fake handwriting, or additional copy.

7. Storefront grand-opening sign

FORMAT: Photorealistic storefront sign at dusk, 3:2.
EXACT TEXT: The mounted sign reads exactly "GRAND OPENING".
HIERARCHY: One line with equal-size words.
TYPE: Dimensional brushed-brass uppercase letters, clean sans-serif, even kerning.
PLACEMENT: Centered above a dark wood entrance, physically attached to the facade.
VISUAL: Soft streetlamp illumination, subtle brass highlights, believable shadows cast by each raised letter.
CONSTRAINTS: No store name, date, sale message, window lettering, people, vehicles, duplicate sign, or watermark.

8. Album-cover title

FORMAT: Square album cover.
EXACT TEXT: Render only "LOW TIDE" and "MARA VALE".
HIERARCHY: LOW TIDE is the main title. MARA VALE is a smaller artist name.
TYPE: Widely tracked uppercase grotesk, pale gray, crisp and understated.
PLACEMENT: Title at the upper left; artist name at the lower left; both aligned to the same grid.
VISUAL: Minimal long-exposure photograph of a dark shoreline before dawn, cool gray-blue palette, fine film grain.
CONSTRAINTS: No record label, track list, parental advisory badge, catalog number, signature, logo, or extra text.

Labels, packaging, and branded surfaces

9. Fictional product label

FORMAT: Front-facing label concept on a fictional amber glass bottle, 4:5.
EXACT TEXT: Render only "FIELD NOTE" / "HAND SOAP" / "250 mL".
HIERARCHY: FIELD NOTE is the brand-sized line, HAND SOAP is secondary, and 250 mL is smallest.
TYPE: Black editorial serif paired with a neutral sans-serif measurement line.
PLACEMENT: Three centered lines on a matte cream rectangular label with consistent margins.
VISUAL: Bottle on pale stone, soft diffused studio light, realistic glass and paper texture.
CONSTRAINTS: Do not invent ingredients, certifications, safety claims, barcode, address, logo, scent, legal copy, or additional measurement.

Use fictional names for exploration. Do not ask a model to imitate a protected brand logo or treat generated packaging as legally complete.

10. Existing package with protected label text

FORMAT: Reference-based product photo edit.
SOURCE: Use the uploaded package as the exact product and label reference.
CHANGE: Replace only the background with a warm-white seamless studio sweep.
EXACT TEXT: Preserve every existing character on the package exactly as visible in the source.
HIERARCHY: Do not redesign, reflow, translate, or restyle any label element.
PLACEMENT: Keep the package camera angle, scale, crop, and label position unchanged.
VISUAL: Large diffused key light, soft fill, controlled reflection, subtle grounding shadow.
CONSTRAINTS: No new badge, claim, ingredient, logo, barcode, decorative text, duplicated package, or altered spelling.

Even with a strong reference, manually compare the final label, logo, regulated claims, volume, and product geometry with the source.

Covers and editorial layouts

11. Book-cover title and author

FORMAT: Vertical literary book cover, 2:3.
EXACT TEXT: Render only "THE QUIET ORBIT" and "LENA MORI".
HIERARCHY: THE QUIET ORBIT is the dominant title across two balanced lines. LENA MORI is the smaller author name.
TYPE: Elegant high-contrast serif, uppercase, off-white, generous letter spacing.
PLACEMENT: Title in the upper half; author centered near the bottom with print-safe margins.
VISUAL: A small observatory beneath a vast indigo night sky, restrained stars, subtle paper grain.
CONSTRAINTS: No review quote, publisher mark, edition label, spine, price, subtitle, awards badge, or extra text.

12. Magazine-cover concept without fake editorial filler

FORMAT: Vertical editorial magazine-cover concept, 4:5.
EXACT TEXT: Render only "FIELDWORK" and "THE COAST ISSUE".
HIERARCHY: FIELDWORK is a large masthead. THE COAST ISSUE is a smaller cover line.
TYPE: Bold white neo-grotesk masthead with a light-weight uppercase supporting line.
PLACEMENT: Masthead across the top; supporting line at the lower right; keep both clear of the subject's face.
VISUAL: Documentary portrait of a fictional marine researcher on a windy shoreline, muted slate and sand palette.
CONSTRAINTS: No barcode, price, date, article list, page number, sponsor, logo, or unreadable filler copy.

13. Movie-poster concept

FORMAT: Vertical cinematic poster, 2:3.
EXACT TEXT: Render only "SIGNAL NORTH" and "A FILM BY ELI WREN".
HIERARCHY: SIGNAL NORTH is the dominant title; the credit line is small but readable.
TYPE: Wide uppercase sans-serif, cold white, subtle weathered texture without broken letters.
PLACEMENT: Title in the lower third; credit line directly beneath; clear safe area around both.
VISUAL: Lone radio tower in a snowfield at blue hour, distant red warning light, atmospheric but uncluttered.
CONSTRAINTS: No actor names, release date, festival laurels, rating, studio logo, billing block, quote, or additional credit.

Do not request a dense Hollywood-style billing block if exact legal credits matter. Add verified credits later as editable type.

Multilingual and localized text

14. Bilingual event title

FORMAT: Vertical bilingual cultural-event poster, 4:5.
EXACT TEXT: Render these lines exactly: "NIGHT MARKET" / "夜市" / "SATURDAY".
HIERARCHY: NIGHT MARKET and 夜市 have equal prominence. SATURDAY is smaller.
TYPE: Clean bold sans-serif for English, compatible bold Gothic-style Chinese type, warm white.
PLACEMENT: English and Chinese titles stacked in the center; SATURDAY below with generous spacing.
VISUAL: Deep red background with a restrained paper-lantern silhouette and subtle paper texture.
CONSTRAINTS: Keep English and Chinese as separate correct lines. Do not translate, romanize, add another language, duplicate characters, or invent venue details.

When the wording matters, supply the approved translated string yourself. Do not rely on the image model to create legal, medical, or public-safety translations.

FORMAT: Square localized social announcement.
EXACT TEXT: Render only "OUVERTURE" and "SAMEDI 10 H".
HIERARCHY: OUVERTURE is large; SAMEDI 10 H is smaller.
TYPE: Dark navy geometric sans-serif, uppercase, clear accents and spacing.
PLACEMENT: Left aligned in the upper-left quadrant with wide margins.
VISUAL: Pale yellow background with a simple cobalt doorway illustration at the lower right.
CONSTRAINTS: Preserve the French wording exactly. No English translation, address, date, logo, button, URL, hashtag, or filler text.

Infographics and information graphics

16. Three-step process card

FORMAT: Vertical three-step process graphic, 4:5.
EXACT TEXT: Render only "1 PLAN" / "2 BUILD" / "3 REVIEW".
HIERARCHY: All three steps have equal weight and identical formatting.
TYPE: Bold dark-gray sans-serif with large coral numerals.
PLACEMENT: Three horizontal rows stacked vertically, each with one simple geometric icon and ample white space.
VISUAL: Clean off-white background, thin gray dividers, consistent grid, accessible contrast.
CONSTRAINTS: Preserve numeral-word pairs and order. No explanatory paragraph, arrows that skip steps, fourth step, logo, footer, or microtext.

For data, instructions, or safety-critical diagrams, validate every fact outside the image. Raster output is not a reliable source of truth.

Editing existing text inside an image

17. Correct one misspelled word

FORMAT: Precise reference-image text correction.
SOURCE: Use the uploaded poster as the base image.
CHANGE: Replace only the misspelled word "WELLCOME" with "WELCOME".
PRESERVE: Keep every other word, letter, number, font characteristic, size, color, kerning, line break, position, image, texture, crop, and lighting unchanged.
MATCH: Reconstruct the corrected word in the same type style and make the edited area visually continuous with the surrounding print texture.
CONSTRAINTS: Do not rewrite the sentence, alter other letters, move the text box, sharpen the whole image, change colors, or add any mark.

18. Replace a date without redesigning the flyer

FORMAT: Precise reference-image text replacement.
SOURCE: Use the uploaded flyer as the base image.
CHANGE: Replace only "MAY 12" with "MAY 19".
PRESERVE: Keep all other text, spelling, typography, alignment, spacing, graphics, people, logos, colors, shadows, crop, and texture unchanged.
MATCH: Use the same font weight, character width, baseline, color, print grain, and perspective as the original date.
CONSTRAINTS: The final date must read exactly MAY 19 once. Do not alter the year, time, venue, price, or any unrelated pixel.

19. Preserve existing signage during a photo edit

FORMAT: Reference-based environmental photo edit.
SOURCE: Use the uploaded street photograph as the base image.
CHANGE: Change only the time of day from noon to natural blue hour.
PRESERVE: Keep every existing sign, storefront name, road marking, license plate, object, building, person, camera position, and crop unchanged.
TEXT RULE: All visible wording must retain the exact source spelling, script, order, perspective, material, and placement.
VISUAL: Add restrained cool ambient light and illuminate only existing practical lights with believable reflections.
CONSTRAINTS: No new neon sign, translated text, fake business, changed logo, added vehicle, rain, or fantasy color.

The reliable fallback for long copy

20. Generate the artwork, reserve the type area

FORMAT: Vertical event-flyer background, 4:5.
TEXT: Render no readable text.
LAYOUT: Reserve a clean, low-detail rectangle in the upper third for a future headline and a second clean strip along the bottom for date, venue, and ticket details.
VISUAL: Abstract folded-paper forms in deep violet and coral, directional studio light, subtle grain, energetic but controlled composition.
CONTRAST: Both reserved areas must have even dark backgrounds suitable for later white typography.
CONSTRAINTS: No letters, numbers, symbols, logo, pseudo-writing, poster mockup, border, badge, QR code, or watermark.

Use this fallback when the final asset contains paragraphs, many prices, addresses, schedules, legal terms, a QR code, or exact brand typography. Generate the visual concept, then add approved copy as editable text in Canva, Figma, Photoshop, Affinity, or another layout tool. This is not a failure of the workflow; it is the safer production boundary.

Exact-text preflight checklist

Before paying for a generation, check the prompt:

Copy is final. Dates, prices, names, addresses, translations, punctuation, and capitalization have been approved.
Every required string is quoted. The prompt distinguishes exact copy from visual instructions.
Hierarchy is explicit. It names the primary, secondary, and supporting lines.
Type is concrete. It specifies category, weight, case, color, spacing, and material where relevant.
Placement is measurable. It uses positions such as upper third, lower left, centered, or aligned to one grid.
Contrast is planned. Text does not sit across a face, busy texture, or bright highlight.
Extra copy is forbidden. No invented badge, sponsor, microtext, watermark, barcode, or filler paragraph.
The fallback is defined. If exact copy fails, keep the visual and rebuild the type as an editable layer instead of repeatedly spending credits.

Research continues to identify text rendering as a difficult benchmark even for recent image models. For example, GlyphBanana proposes a multi-stage workflow specifically for complex glyphs and formulas, while a recent natural-science illustration benchmark reports persistent difficulty balancing rich images with precise text. These papers do not measure this website’s editor, but they support the practical rule that generated text still requires inspection.

Diagnose the failure before regenerating

Failure	Likely prompt gap	Lower-waste revision
A letter is wrong	exact copy was mixed into prose	isolate the quoted string and request only that text
Extra words appear	empty areas were left undefined	forbid badges, filler, microtext, and secondary copy
Line order changes	hierarchy was implied	enumerate each line and state the order
Text covers the subject	no placement or negative space	reserve a named region before describing the artwork
A date or price mutates	numbers were not protected	quote the full string and call out confusable characters
Multilingual copy mixes scripts	language boundaries were vague	supply approved strings as separate lines and forbid translation
Existing text changes during an edit	preservation scope was too broad	name every text-bearing region that must stay unchanged
Long copy stays unreliable	the task exceeds a raster generator’s safe boundary	create background-only art and add editable type afterward

Change one variable at a time. If the composition is correct but one word is wrong, do not rewrite the visual style, lighting, and layout in the same revision.

Final review before publishing

Zoom in and compare the image against the approved source copy character by character. Then verify:

spelling, punctuation, accents, capitalization, line breaks, and reading order;
dates, time zones, prices, currency, units, phone numbers, URLs, and addresses;
brand names, trademarks, packaging claims, ingredients, certifications, and disclaimers;
contrast, margins, alignment, visual hierarchy, and mobile-size legibility;
whether the final file needs editable or accessible text outside the image.

For important information, repeat the text in HTML, a caption, or accessible document content. Words baked into pixels are not a substitute for accessible page text.
