60 Social Media prompts to copy

Every prompt below links to the full prompt page with the image and copy button.

Social feeds are a design problem before they are a copy problem. The image has to work at the size of a thumbnail, in a busy column, next to everything else in the feed. That means one clear focal point, high contrast, and space where the platform will overlay its own UI.

These prompts are written for that constraint: bold single subjects, strong colour blocking, negative space for captions, and formats sized for feed posts, stories, thumbnails and carousels. They lean on the styles that survive compression — flat illustration, poster-style typography backing, high-contrast studio lighting and saturated editorial colour.

Use them for organic posts, paid creative drafts, channel art and YouTube thumbnails. The guide explains how to keep the subject clear at small sizes and how to leave room for text overlays.

Why use prompts for social visuals

Social media prompt guide

Design for the thumbnail

Ask for one dominant subject, high contrast and a simple background. If the idea only works at full size, it will fail in the feed — check the output at 20% zoom before you commit.

Leave space for the caption

Say 'generous negative space on the left third' or 'clear space at the top for text'. Platforms crop differently in feed, story and reels placements, so keep the subject away from the edges.

Match the aspect ratio to the placement

1:1 for feed, 4:5 for the tallest feed real estate, 9:16 for stories and shorts, 16:9 for thumbnails. Write the ratio into the prompt and crop conservatively afterwards.

Keep text minimal

Models still break on long strings of text. Generate the visual and add the words in your editor unless the typography itself is the concept.

Social media prompts FAQ

What sizes should I generate for social?
Generate square by default, then crop: 1080x1080 for feed, 1080x1350 for 4:5, 1080x1920 for stories and reels, 1280x720 for thumbnails. Starting from a larger square and cropping down is safer than generating each ratio separately.
Are AI images allowed in ads?
Most platforms allow AI-generated creative as long as it is not misleading and follows their advertising policies — no fake product claims, no prohibited categories. Some networks require disclosure for synthetic content, so check the current rules for your placement.
How do I make a scroll-stopping thumbnail?
One subject, one emotion, strong contrast against the platform's background, and no clutter. Faces and hands out-perform abstract graphics, and extreme close-ups beat wide shots at thumbnail size.
Which model is best for social visuals?
GPT Image for anything with clean graphic composition, Midjourney for editorial moods, FLUX for photoreal product and people shots. All the prompts here are written to be portable.
Can I build a whole content calendar from these?
Yes — generate a batch, keep the ones that pass the small-size test, and reuse the same lighting and palette sentences so a month of posts looks like one brand rather than ten.
