Social Media Image Sizes in 2026: Instagram vs Facebook vs LinkedIn (and How to Resize Them)
Short answer: Use 1080 × 1350 px (4:5 portrait) for feed images on Instagram, Facebook and LinkedIn, and 1080 × 1920 px (9:16) for Stories and Reels. Use 1200 × 630 px for Facebook link previews and 1200 × 627 px for LinkedIn landscape posts. Square 1080 × 1080 px images still work everywhere if you want one file for all three.
