The Ultimate Social Media Image Dimensions Cheat Sheet for 2026
Never post a blurry or awkwardly cropped image again. Here are the exact pixel dimensions for Instagram, YouTube, Facebook, LinkedIn, and X.
Social media platforms continually adjust their feed layouts and compression algorithms. If you upload an image with incorrect aspect ratios, the platform’s automatic crop tool can cut off critical text or compress your visuals into blurry artifacts.
Instagram feeds recommend 1080 x 1080 pixels for square posts and 1080 x 1350 pixels for 4:5 portraits. For Stories and Reels, the standard is 1080 x 1920 pixels (9:16 vertical).
For YouTube creators, your video thumbnail should be exactly 1280 x 720 pixels (minimum 640px wide) in a 16:9 ratio, kept under 2MB. Facebook covers display best at 820 x 312 pixels on desktop and 640 x 360 pixels on mobile devices.
