Below is the verified 2026 social media dimension guide, along with step-by-step instructions on how to batch-resize images in seconds using the FreeImgLab Bulk Image Resizer.

6. Open Graph (OG) & Web Link Previews

When links to your website or blog are shared on WhatsApp, iMessage, Slack, LinkedIn, or Facebook, the crawler fetches the <meta property="og:image"> tag:

• Optimal Resolution: 1200 × 630 px (Aspect ratio 1.91:1)
• File Weight: Under 300 KB (for instant preview rendering).
• Safe Zone Rule: Keep titles, logos, and critical subject matter centered within the middle 1080 × 566 px box to avoid clipping when platforms crop to square previews on mobile.
