AI Prompts for Nano Banana Social Media Graphics Prompts: On-Brand Posts in Minutes

Act as a social media art director. My brand is [BRAND / WHAT I DO] for [AUDIENCE], and my current feed looks like this: [DESCRIBE OR LIST RECENT POST TYPES]. Diagnose the visual problems in priority order: inconsistent colors, mixed typography energy, no recognizable template, competing styles between photo posts and graphic posts. Then define what one glance at three of my posts side by side should communicate, and the two or three visual constants that would make my feed recognizable at scroll speed.

Create my reusable visual identity block for Nano Banana generations. Brand: [BRAND] serving [AUDIENCE] with a personality that is [ADJECTIVES: E.G. CALM AND EXPERT / BOLD AND IRREVERENT / WARM AND CRAFT-FOCUSED]. Define: a palette of one dominant background color, one accent, and one neutral with hex values, the typography mood for rendered text (clean geometric sans / elegant serif / hand-lettered), the illustration or photo treatment (flat illustration / soft 3D / photographic with consistent grade), texture and depth rules, and the recurring signature element that appears in every post. Write it as one paragraph I paste into every prompt.

For my brand on [PLATFORMS: INSTAGRAM / LINKEDIN / X], choose the five recurring post formats worth systematizing based on what I publish: [CONTENT TYPES: TIPS, PRODUCT UPDATES, QUOTES, BEHIND-THE-SCENES, DATA POINTS]. For each format define: its job (save, share, click, comment), the layout skeleton (headline zone, visual zone, brand mark position), how much rendered text it carries, and how often it appears in the weekly mix. The goal is a feed with rhythm: formats repeat, content changes.

Nano Banana renders real text inside images, so my graphics can carry actual headlines. Define my text hierarchy for social graphics: the maximum headline length that stays readable on a phone at feed size, the size relationship between headline, supporting line, and brand handle, contrast rules so text passes readability on my palette, and the placement zones that survive platform UI overlays on [STORIES / REELS COVERS / FEED POSTS]. Give me three example headline treatments written out exactly as I would put them in a prompt.

Build my weekly social graphics production plan: [NUMBER] posts per week across [PLATFORMS]. Map each slot to one of my five formats, define the visual variation allowed within each format (background color rotation from my palette, alternating illustration subjects) versus what never changes (layout skeleton, typography mood, signature element), and sequence the week so the feed alternates text-heavy and visual-heavy posts. End with the batch plan: which graphics to generate in one session so the set stays consistent.

Create a square 1:1 social media announcement graphic. [PASTE IDENTITY BLOCK]. Layout: bold headline reading exactly "[HEADLINE TEXT]" in the upper two thirds, rendered in my typography style, high contrast against a [BACKGROUND: DOMINANT BRAND COLOR / SUBTLE GRADIENT OF MY PALETTE] background, a supporting line below reading exactly "[SUPPORT TEXT]" at one third the headline size, my brand handle "[@HANDLE]" small at the bottom, and [VISUAL ELEMENT: A SIMPLE ILLUSTRATION OF X IN MY STYLE / CLEAN GEOMETRIC SHAPES FROM MY PALETTE] balancing the composition. Modern social media design, generous margins, text perfectly legible at phone size.

Create a square quote card graphic. [PASTE IDENTITY BLOCK]. The quote reads exactly: "[QUOTE TEXT]" with attribution "[NAME, TITLE]" beneath it at smaller size. Typography-led design: the quote is the hero, set large with deliberate line breaks for rhythm, opening quotation mark as an oversized graphic element in my accent color, [BACKGROUND: SOLID BRAND COLOR / SOFT TEXTURED WASH], my signature element placed subtly, brand handle at bottom edge. Editorial, calm, extremely readable, the kind of card people screenshot and share.

Create the cover slide for an Instagram carousel, 4:5 portrait. [PASTE IDENTITY BLOCK]. Cover headline reads exactly "[HEADLINE: E.G. 5 MISTAKES KILLING YOUR MORNING ROUTINE]" set large and bold with a visual hook: [HOOK ELEMENT: A BOLD NUMBER 5 AS A GRAPHIC ANCHOR / AN ILLUSTRATION TEASING THE PAYOFF], plus a small "swipe" cue bottom right. Then describe the interior slide template as a variation of this cover: same background family and typography, headline zone at top, body text zone center at readable size, slide number indicator, so I can generate slides 2 through [N] by changing only the text.

Create a 9:16 vertical background for Stories and Reels covers. [PASTE IDENTITY BLOCK]. Design: an atmospheric composition from my palette, [STYLE: SOFT GRADIENT WITH GRAIN / FLAT ILLUSTRATION SCENE / ABSTRACT SHAPES WITH DEPTH], visual interest concentrated in the middle band of the frame, deliberately calm zones at the top 15 percent and bottom 20 percent where platform UI and captions overlay, optional headline reading exactly "[TEXT]" positioned in the safe middle zone. It should feel on-brand even with nothing added, and never fight the text I will place over it.

Create a square social graphic presenting one statistic. [PASTE IDENTITY BLOCK]. The stat reads exactly "[NUMBER/STAT]" rendered huge as the visual hero in my accent color, with the context line "[WHAT THE STAT MEANS]" beneath at much smaller size, and source credit "[SOURCE]" in small type at the bottom. Support the number with a minimal visual: [A SIMPLE CHART BAR RISING / A CLEAN ICON / ABSTRACT SHAPES SUGGESTING THE TREND], nothing that competes with the number. Confident editorial infographic style, lots of breathing room, instantly readable while scrolling.

Keep this graphic exactly as it is, same layout, colors, illustration, and composition, but correct only the text: the headline must read exactly "[CORRECT TEXT]" with no spelling changes, substitutions, or missing characters. Keep the same font style, size, color, and position. If any letter renders imperfectly, prioritize clean legible letterforms over decorative styling.

This graphic is too crowded. Keep the same content and brand style but rebalance: increase the margins around the edges, create more space between the headline and the supporting elements, shrink [ELEMENT] by about a third, and let the background breathe. Nothing new added. The test: the headline should be the first thing seen, the visual second, the handle last, with a half-second pause between each.

Keep this graphic’s exact layout, typography, text, and illustration, but produce [NUMBER] color rotation variants using only my brand palette: one on the dominant color background, one on the neutral, one inverted with the accent as background. Text contrast must remain fully readable in every variant, adjusting text color between my palette options as needed. These are for feed rhythm: same post family, different tones.

Take this finished square graphic and adapt it: a 4:5 portrait version for the Instagram feed with the composition extended vertically rather than stretched, a 9:16 Story version where the headline moves into the middle safe zone and the background extends naturally to fill the frame, and a 1.91:1 landscape version for LinkedIn and X where the layout shifts to headline left, visual right. Keep text, brand elements, and style identical in every version, and recompose rather than crop.

Review this graphic as a scroll-stopping test, not a design critique. At feed size on a phone: does the headline read completely in under one second, does the color break the pattern of a typical feed or blend in, is there one clear focal point or three competing ones, does it look like my last five posts (good: recognizable) or identical to them (bad: invisible), and would a stranger understand what is being said without the caption. Score each harshly out of ten, and for anything under eight give me the exact one-line edit instruction to fix it.

I am batch-producing this week’s graphics. My five formats and identity block: [PASTE]. This week’s content: [LIST: MONDAY TIP ABOUT X, WEDNESDAY QUOTE FROM Y, FRIDAY ANNOUNCEMENT OF Z]. Generate the production run order that maximizes consistency: all same-format posts back to back, color rotation assigned across the week so no two adjacent posts share a background, and each prompt written out ready to paste with the real text inserted. Flag any headline that exceeds my length limit and rewrite it shorter first.

This graphic announces [CAMPAIGN/LAUNCH]. Build the full campaign set from it, keeping the visual family unmistakable: a teaser version with the headline replaced by "[TEASER TEXT]" and a partial reveal treatment, the main announcement as-is, a social proof version where the headline is swapped for the quote "[TESTIMONIAL]", a last-call version with "[URGENCY TEXT]" and a subtle intensity increase (deeper accent color, tighter crop), and Story versions of each. One family, four escalating beats.

I want a recurring series called "[SERIES NAME: E.G. MONDAY MYTHS]" that people recognize instantly. Design the series template as a locked variation of my identity: a fixed series header treatment reading "[SERIES NAME]" in the same position every time, a numbered episode indicator, one slot that changes per episode ([THE MYTH / THE TIP / THE QUOTE]), and a fixed closing element. Generate the template with episode one content: [CONTENT], then give me the one-line instruction I reuse to produce every future episode by swapping only the content slot.

My feed identity has run for [DURATION] and feels stale. Evolve it without breaking recognition: identify which elements carry recognition equity (palette, signature element, typography) and must survive, which can rotate (illustration subjects, backgrounds, layout details), and design the refreshed identity block that keeps the first group and updates the second. Show the evolution on my most-used format: current version beside refreshed version, close enough that followers feel continuity, fresh enough that regulars notice.

Document this system so anyone (including future me) can produce on-brand graphics: the identity block with palette hex values and typography mood, the five format templates with their generation prompts, the edit recipes for text fixes, rebalancing, and platform adaptation, the weekly grid with format rotation, and the quality bar: the five-point scroll test every graphic passes before publishing. Write it as a single-page operating doc.
