Recommended upload dimensions for each platform. Use the highest resolution shown — platforms downscale cleanly but never upscale. Sizes are kept current with each platform's guidance; always preview before posting as platforms tweak these periodically.
Look up the right image and video dimensions for every major platform — posts, stories, reels, covers, thumbnails and profile pictures for Instagram, Facebook, X/Twitter, YouTube, LinkedIn, TikTok and Pinterest. Upload at the recommended size so platforms downscale cleanly instead of cropping or blurring. Runs in your browser.
