Social Media Image Sizes: Practical Workflow

Platform specs change, but quality problems are usually caused by workflow mistakes, not one missing pixel. This guide focuses on repeatable export steps that prevent blur, random crops, and oversized uploads.

Use-case presets that hold up in practice

These are practical starting points, not strict official specs. They are chosen to keep quality high while staying manageable in size.

  • Square feed: 1080 x 1080 (1:1).
  • Portrait feed: 1080 x 1350 (4:5).
  • Landscape feed or thumbnails: 1200 x 675 (16:9).
  • Story/reel cover style: 1080 x 1920 (9:16).
  • Wide cover/banner: 1500 x 500 to 1600 x 600.

A workflow that avoids re-export loops

  1. Start from the largest clean source you have.
  2. Crop first to the final aspect ratio.
  3. Resize to the target pixel dimensions.
  4. Export once, then compress once.
  5. Check the upload preview on mobile before publishing.

Format choice for social posts

  • JPEG: best default for photos and gradients.
  • PNG: better for graphics, logos, and screenshots with text.
  • WebP: useful when accepted by your workflow and target platform.

If text edges look soft, try PNG or higher JPEG quality. If file size is too large, resize first and then reduce quality gradually.

Safe-zone rule for overlays and crops

Keep critical text and logos inside an inner safe area rather than near edges. A practical rule is to keep key content at least 8% away from each border. This reduces failures when apps crop differently across feed, preview, and profile grid views.

Quick troubleshooting map

  • Looks blurry: export larger source, avoid repeated compression, increase quality one step.
  • Unexpected crop: match target aspect ratio before upload, not after.
  • Text looks muddy: switch from JPEG to PNG for text-heavy visuals.
  • Upload rejected for size: resize dimensions down, then compress again.

Simple production checklist

  • One master file per post design.
  • One export per target ratio.
  • No repeated save/compress cycles on the same output.
  • Final visual check at 100% for text, faces, and edges.
