What are the best image sizes for social media in 2026?
Most platforms render feed images at 1080 pixels wide. The strongest defaults are 1080 x 1440 (3:4) on Instagram, 1080 x 1350 (4:5) on Facebook, 1200 x 1200 on LinkedIn, 1200 x 675 (16:9) on X, 1000 x 1500 (2:3) on Pinterest, and 1080 x 1920 (9:16) for every vertical video format.
Do social media image sizes change every year?
A few change most years, which is why guides go stale. The biggest recent change is Instagram moving its profile grid to a 3:4 preview and adding native 3:4 uploads. The sizes on these pages were checked against current platform documentation in July 2026.
Can I use one image size everywhere?
Almost. A 1080 x 1350 portrait works well on Instagram, Facebook, and LinkedIn feeds, and 1080 x 1920 covers every story, reel, and short. Covers and banners are the exception: each platform's is a different shape, so those need their own crops.
Why do my images look blurry after uploading?
Usually the upload is smaller than the display size, so the platform scales it up, or it is so large that the platform compresses it aggressively. Upload at the recommended pixel size, keep files under each platform's limit, and use PNG for images with text.
