Use these sizes for sharp results:

- Portrait post: 1080 × 1350 (4:5) — takes the most feed space
- Story and Reel cover: 1080 × 1920 (9:16)
YouTube, LinkedIn, X and Facebook
Headers and thumbnails are wide:
- YouTube thumbnail: 1280 × 720, under 2 MB
- LinkedIn banner: 1584 × 396
- X header: 1500 × 500
- Facebook cover: 1640 × 624
- Link preview (Open Graph): 1200 × 630
Keep files light
Platforms recompress uploads anyway. Sending a well-sized JPG at 85–90% quality avoids double compression artifacts and uploads faster on mobile data.
