Social Media AI Image Prompts: Feed, Story & Carousel

Social media AI prompts for images fail when you write caption templates and hope the model invents a crop. Feed, Story, and carousel each need a different canvas, text-safe margin, and subject weight. This page ships image kits: square and 4:5 feed heroes, 9:16 Story frames, and multi-slide carousel systems with shared art direction. Soft path: https://promptmake.net/use-case/social-media. PromptMake writes prompt text from an upload or campaign idea. It does not publish posts, render final JPGs for you as a network publisher, or write full caption calendars. You leave with field order, three kit families, model notes for September 2026, and an FAQ. Add logos and final type in a design tool.

Who these social media AI prompts serve

Social teams, founders, and freelancers need stills that survive phone chrome: avatar overlays, swipe arrows, sticker trays, and headline boxes. A vague ask like "make an Instagram post" produces busy centers and clipped faces. Name the placement first, then subject, light, palette, and empty zones.

Use this page for visual prompt text aimed at Midjourney v7, FLUX, GPT Image, Ideogram, Leonardo, or SDXL. Use the separate platform text-template article on this blog when you need caption hooks and thread structures. Stay here for pixels and composition.

PromptMake's social path accepts a reference still or a short campaign brief, then returns editable image prompt text. Guests get about three image generations per day on that path. Free accounts get about five. Quotas are separate from text tools. Soft start: https://promptmake.net/use-case/social-media.

Confirm live platform sizes before client delivery. Apps change safe areas. Leave margin even when the generator canvas matches the target ratio.

Strong fit when you ship the same product across feed, Story, and a five-card carousel in one week. Weak fit when you only need tweet copy or LinkedIn hooks. Those jobs belong in text templates, not image kits. Soft visual CTA remains https://promptmake.net/use-case/social-media.

Field order before you generate

Lock placement and aspect before style words. Write: platform slot, ratio, subject, composition, brand palette, lighting, text-safe zones, bans. That order matches how art directors brief a social shoot: where it lives, what is in frame, how brand shows, where type will sit later.

Placement line: Instagram feed portrait, LinkedIn feed square, Story, Reel cover, carousel slide 2 of 5. Ratio line: Midjourney --ar 4:5, --ar 1:1, or --ar 9:16; FLUX or GPT Image presets that match. Subject line: product, person, or scene with one hero. Brand line: two or three palette nouns, material, contrast rule. Safe-space line: "empty upper third for headline," "lower fifth clear for CTA," "face in upper third for Story." Ban line: cluttered UI mockups, fake logos, unreadable fake type when you plan real type in post.

Series consistency comes from a fixed art-direction block reused across posts. Change one subject or benefit per asset. Soft assist when you hold a brand still: upload at https://promptmake.net/use-case/social-media, Recreate or Change Style, then hand-edit locks before paste.

Aspect and safe-space checklist

Feed portrait: --ar 4:5 fills more phone screen than 1:1 on many Instagram feeds. Feed square: --ar 1:1 for catalogs and profile-adjacent tiles. Story / Reel cover: --ar 9:16 with headroom and side margin for stickers. Carousel cards: pick one ratio for the whole set; mixed ratios break swipe rhythm.

Keep faces and logos away from edges. Preview at phone size. Do not judge only a large desktop render.

Brand lock checklist

Repeat palette nouns, lighting direction, camera distance, and background system. Example lock: "cobalt and mint, soft key from camera left, medium product distance, matte paper backdrop." Vary only the hero object or benefit icon per slide. Ban competing weather and light in one sentence.

Feed kit: square and portrait heroes

Feed social media AI prompts sell one idea at arm's length. Center or rule-of-thirds the hero. Leave a calm quadrant for type you will add later. Prefer one product or one face. Busy collages die in the scroll.

Skeleton (Midjourney-shaped): [hero subject], [setting], [light], [palette], empty [corner/zone] for headline, clean advertising still --ar 4:5 --style raw --v 7. FLUX gets the same prose plus a 4:5 or 1:1 UI preset. GPT Image gets an orientation sentence plus the prose stack.

Product feed example: "Chilled citrus sparkling can on wet stone, bright summer sun, sharp condensation, energetic shadows, headline space upper left, cobalt label accents, catalog photo --ar 4:5 --style raw --v 7." Portrait feed example: "Founder half-body against soft sage wall, natural window light camera left, calm smile, lower fifth clear for name plate, editorial photo --ar 4:5." Soft path when you already shot the can: https://promptmake.net/use-case/social-media.

Feed mistakes that waste credits

Generating 1:1 then cropping to 4:5. Writing five product claims into one still. Asking the model for perfect on-image legal text. Crowding the center where Instagram UI already competes.

Feed variation habit

Lock ratio and brand block. Change only pose, prop, or background texture across a week of posts. Save winners with ratio in the filename (feed_4x5_citrus_v2.png).

Story kit: vertical frames that survive chrome

Story and Reel-cover social media AI prompts need tall composition. Put the face or product in the upper third. Keep the vertical center readable. Leave edge margin for reply stickers and progress bars. Soft natural light or one studio key beats neon overload on small screens.

Skeleton: [subject], vertical 9:16 frame, [light], [palette], clear center text-safe band, [mood], phone-first photo --ar 9:16. Yoga studio example: "Morning yoga class beside tall windows, warm neutrals, diverse adults mid-pose, soft natural light, clear center band for studio name, calm Story frame --ar 9:16." Launch Story: "Sneaker on recycled paper forms, moss green accents, low three-quarter angle, soft key, lower third clear for swipe-up type zone --ar 9:16."

For Reel covers, treat the first frame like a thumbnail: one readable gesture, high contrast, no tiny type from the model. Soft draft from a vertical phone still at https://promptmake.net/use-case/social-media with Recreate Exactly, then enforce --ar 9:16 on paste.

Story composition rules

Avoid tiny subjects lost in empty sky. Avoid text baked into the pixels when you will overlay real captions. Avoid horizontal group shots that force harsh crops into 9:16.

Story series locks

Same wall color, same key direction, same camera height across a five-day Story sequence. Change wardrobe or prop only. Viewers should feel one brand day, not five unrelated shoots.

Carousel kit: shared system, one idea per slide

Carousel social media AI prompts need a modular grid. Write a shared art-direction block once. Then write slide-specific subject lines. Keep icon style, corner radius language, and palette identical. One benefit per slide. Soft cobalt and mint 3D icon systems work when you name materials (matte plastic, soft clay, flat vector) so the model does not hop mediums mid-set.

Shared lock example: "Cobalt and mint 3D icons, soft matte plastic, soft studio light, modular grid, clean brand system, white negative space for captions." Slide 1: "Hero icon: wallet with gentle pulse." Slide 2: "Hero icon: calendar check." Slide 3: "Hero icon: chart up." Midjourney: repeat the lock and end every slide with the same --ar 1:1 or --ar 4:5. Soft assist: generate slide 1 at https://promptmake.net/use-case/social-media, then Create Variation for siblings while you keep the lock paragraph fixed.

Carousel production steps

1. Lock ratio for all slides. 2. Write the shared brand block. 3. List one benefit per slide in plain words. 4. Generate slide 1. 5. Clone the lock for slides 2-N; change only the hero noun. 6. Reject any slide that breaks palette or medium. 7. Add real type and page dots in a design tool.

Carousel failure modes

Different ratios per slide. New lighting recipe each card. Asking one prompt to invent five scenes without a shared lock. Baking slide numbers into AI type instead of adding them in design.

Model notes for September 2026

Midjourney v7 (and V8 Alpha where you have access): put --ar at the end; use --style raw for photo-led feeds. FLUX: natural-language stack plus host aspect preset. GPT Image / ChatGPT Images: conversational size plus follow-up "keep upper third empty." Ideogram helps when you need on-image type experiments; still prefer design-tool type for legal copy. Leonardo and SDXL: set canvas pixels or presets to match 1:1, 4:5, or 9:16 before you spend the run.

PromptMake /image and the social use-case path format for Midjourney, FLUX, DALL·E, Stable Diffusion, and Leonardo targets as shown in the tool. Soft CTA stays on https://promptmake.net/use-case/social-media for this article. Confirm live model chips; names shift.

Campaign workflow tip: generate the feed hero first, then restyle the same subject into 9:16 with Change Style or a fresh Story kit that reuses palette and light nouns. Do not stretch a 4:5 winner into a Story in a photo editor if the face already sits on the crop line. Regenerate with --ar 9:16 so composition rebuilds for phone chrome. Soft upload path when the brand still exists: https://promptmake.net/use-case/social-media.

Paid social adds another constraint: ads policies and safe zones differ from organic feed. Leave more margin than organic posts, avoid fake UI chrome that looks like platform buttons, and keep claims out of baked AI type. Treat generative stills as creative drafts until brand, legal, and accessibility checks pass.

Common mistakes with social media AI image prompts

Writing caption copy into the image brief and skipping aspect. You get a mood board, not a post. Put placement and --ar (or the host preset) in the first lines, then subject and light.

One canvas for feed and Story. Crops destroy faces. Regenerate for 9:16 instead of stretching a 4:5 hero.

Fake logos and fake UI. Brand risk and unreadable chrome. Leave logo and CTA zones empty; composite real marks later.

Changing palette every carousel slide. The set feels like five brands. Lock the art-direction paragraph and change only the hero noun.

Judging only desktop zoom. Check phone feed size. Tiny products that look fine on a monitor vanish in the scroll.

Expecting PromptMake to publish. It returns prompt text. You generate elsewhere and schedule in your social tool. Soft honesty: https://promptmake.net/use-case/social-media writes prompts, not network posts.

FAQ

What are social media AI prompts for images?

Social media AI prompts for images are brief stacks that lock placement, aspect ratio, subject, brand look, lighting, and text-safe space before you generate stills for feed, Story, or carousel. Soft drafting: https://promptmake.net/use-case/social-media.

Which aspect ratio should I use for feed vs Story?

Many Instagram portrait feeds start at 4:5. Squares (1:1) still work for catalogs. Stories and Reel covers use 9:16. Keep one ratio across a carousel set. Confirm current platform specs before client handoff.

Does PromptMake post to Instagram or LinkedIn?

No. PromptMake generates editable image prompt text from an upload or idea. You paste into Midjourney, FLUX, GPT Image, or another generator, then publish from your social stack. Soft start: https://promptmake.net/use-case/social-media.

How do I keep a carousel consistent?

Write one shared art-direction paragraph and change only the hero subject per slide. Match ratio, palette, light, and medium. Reject slides that break the lock. Add real captions in a design tool.

Should I generate on-image text with the model?

Short decorative words can work on Ideogram-class tools. Legal headlines, prices, and disclaimers belong in a design tool where spelling stays exact. Leave empty zones in the prompt for that type.

How is this different from social media text templates?

Platform caption and thread templates live in a separate article. This page covers feed, Story, and carousel image kits only. Soft visual path: https://promptmake.net/use-case/social-media.

How do I start on the free tier?

Open https://promptmake.net/use-case/social-media, upload a brand still or describe the slot (feed 4:5, Story 9:16, carousel lock), generate, edit safe-space lines, then paste into your image host. Guests get about three image runs per day; free accounts about five as of mid-2026.
