Quick answer

A social image prompt should define platform format, audience, hook, subject, layout, and safe whitespace. The best template is reusable because it separates creative direction from channel requirements.

Prompt template

Create a [platform format] image for [audience]. Hook: [message]. Subject: [main visual]. Layout: [center/right/left/negative space]. Mood: [emotion]. Colors: [palette]. Leave clean space for headline. Do not include readable text inside the image.

Step-by-step workflow

  1. Start with the channel size: square, vertical, horizontal, or thumbnail.
  2. Write the audience and hook before describing the visual style.
  3. Reserve whitespace for text overlays instead of asking the model to write the headline.
  4. Generate three mood variants: calm, bold, and premium.
  5. Use the best variant as a reference for future campaign consistency.

Example prompt variants

  • Vertical Instagram story background for indie app founders, hook about saving time, clean desk with glowing dashboard, deep green palette, space at top for headline.
  • Square LinkedIn post image for B2B marketers, abstract product workflow cards, confident but calm mood, blue and graphite palette, no text.
  • YouTube thumbnail background for AI tutorial, creator desk setup with prompt cards and image previews, high contrast, space on left for title.

Quality checklist

  • The image reads clearly at feed size.
  • There is intentional space for copy.
  • The visual hook matches the audience problem.
  • No generated text competes with your designed overlay.

Mistakes to avoid

  • Asking the model to include exact headline text in the image.
  • Ignoring platform crop and then losing the subject.
  • Using one generic style for every audience and campaign.
