About this tool

Social Media Image Sizes is a fast, searchable reference for the recommended image and video dimensions on every major network: Instagram (square, portrait, landscape, story, reel, video cover), Facebook (profile photo, cover photo, shared image, event cover, group cover, story, reel), Twitter / X (profile, header, feed image, summary large image and summary cards), LinkedIn (personal photo, personal banner, company logo, company cover, feed post, link share), YouTube (channel profile picture, channel banner with TV-safe area, video thumbnail, Short, standard video), TikTok (profile photo, vertical video, photo-mode carousel), Threads (profile photo, feed post, link preview), Pinterest (profile, cover, standard Pin, square Pin, Idea Pin), Bluesky (profile photo, banner, feed image), and Snapchat (Snap, Spotlight). Each entry lists the recommended pixel dimensions, the aspect ratio reduced to its simplest form (1:1, 4:5, 9:16, 16:9, 2:3, 1.91:1, and so on), the platform-published maximum file size where one exists, the file formats the platform accepts (JPG, PNG, GIF, WEBP, MP4, MOV), and a one-sentence note covering the gotchas that bite people in production: profile photos that are cropped to a circle and need square upload, banners with safe-area constraints (YouTube's central 1546x423 TV-safe region, LinkedIn's lower-left avatar overlap, Facebook cover photos that crop differently on mobile and desktop), stories and reels with top and bottom UI strips that hide caption text, and Open Graph link previews that use a 1.91:1 image. A search box accepts platform names, format keywords (story, reel, banner, thumbnail, cover, headshot), aspect ratios (9:16, 1:1, 16:9, 4:5), and pixel strings (1080x1920, 1280x720) so finding the right spec takes one keystroke. A platform filter lets you focus on one network at a time. The detail panel renders a true-to-ratio rectangle so you can see the spec at a glance, plus one-click copy buttons for the dimensions string, the aspect ratio, a CSS aspect-ratio declaration ready to drop into a stylesheet, and a full plain-text spec block for design briefs. All sizes are drawn from each platform's public help centers and developer documentation as of early 2026 and will need a refresh when platforms change them. The whole tool is static reference data plus a search and filter UI, so nothing about your queries leaves your browser.
