Getting your Facebook link preview image right is more nuanced than most people realize. Use the wrong dimensions and your carefully designed image gets cropped in unexpected ways, ruining the visual impact of your shared links. This guide covers every image size scenario you'll encounter on Facebook in 2025.
The Universal Standard: 1200×630px
The gold standard for og:image is 1200×630 pixels at a 1.91:1 aspect ratio. This size renders perfectly on Facebook desktop, mobile, and in the news feed. It also works well on Twitter (X), LinkedIn, and WhatsApp, making it the safest choice if you want one image that works everywhere.
💡 Important: Facebook requires your og:image to be at least 200×200px to display at all. Images smaller than 600×315px will display in a small format rather than the large card format.
Facebook Large Card vs. Small Card
Facebook displays two types of link preview cards. The large card (with the image above the text) appears when your og:image is at least 600×315px. The small card (with a thumbnail to the left of the text) appears for smaller images. For maximum visual impact and CTR, always aim for the large card format by using 1200×630px images.
Common Cropping Issues and How to Fix Them
The most common issue is important content (like text or faces) being cropped on mobile. Facebook crops images differently on mobile vs. desktop. To avoid this, keep all critical content within the center 80% of your image, leaving safe margins on all sides. Avoid placing text or logos near the edges.
Key Takeaway
The bottom line: use 1200×630px JPG images for your og:image tag, keep critical content centered, and always test your previews before publishing. Use PreviewPro to see exactly how your image will appear across Facebook, Twitter, LinkedIn, and WhatsApp before your content goes live.
