OG Image Sizes for Every Platform in 2026
Getting your Open Graph (OG) image sizes right is crucial for making a great first impression when your content is shared online. Wrong sizes mean cropped images, blurry previews, and lower click-through rates. In 2026, with dozens of platforms and apps competing for attention, nailing your OG images can make the difference between a viral share and a forgotten link.
In this guide, you'll find the exact OG image dimensions for every major platform, common pitfalls to avoid, and how to generate perfect previews with the Imago API.

Universal Recommendation: 1200×630
Use 1200×630 for everything
This size works perfectly across all major platforms and ensures your images look sharp and properly formatted everywhere.
While each platform has slightly different preferences, 1200×630 pixels (1.91:1 aspect ratio) is the safest universal choice. It's large enough to avoid downscaling on any platform and maintains proper proportions across Twitter/X, Facebook, LinkedIn, Slack, Discord, and WhatsApp.
Common OG Image Mistakes to Avoid
- Too small — Images under 600px wide often get pixelated or blurred across platforms
- Wrong aspect ratio — Squared images (1:1) get cropped on some platforms; vertical images get cut off
- Text too close to edges — Critical info may be cut off when platforms add overlays or when images are resized
- Large file sizes — Over 5MB may not load properly or cause delays in preview generation
- Using GIFs for static content — Most platforms will still show a static preview, wasting bandwidth
