Social Media Image Sizes: Practical Workflow

Exact social dimensions change over time, but the workflow for crisp uploads is stable. Use this guide to avoid blurry images, unexpected crops, and oversized files.

Core aspect ratios to prepare

• 1:1 (square) for general feed posts.
• 4:5 (portrait) for taller feed visuals.
• 16:9 (landscape) for banner-like layouts and video thumbnails.

Recommended baseline pixel targets

For many platforms, 1080px on the short side is a strong starting point for feed assets. For header/banner placements, wider exports such as 1500px+ are often safer. If brand detail is small, export larger and test on mobile first.

Reliable export workflow

1. Create and crop for the target aspect ratio first.
2. Resize to final delivery dimensions.
3. Compress once for web delivery.
4. Preview on mobile and desktop before publishing.

Text and logo safety

Keep important text/logos away from edges. Different placements and app previews can crop unexpectedly. Maintain safe margins so your message survives platform UI overlays and auto-cropping behaviors.

Common upload issues and fixes

• Blurry output: export larger dimensions and avoid repeated recompression.
• Unexpected crop: confirm aspect ratio before upload.
• Large file warning: lower quality slightly after resizing.
