Why correct image sizes matter
Uploading the wrong aspect ratio forces platforms to crop your image automatically. Important text, faces, or product details get cut off. Correct dimensions also keep files sharper because platforms apply less aggressive compression.
Always design for mobile first. Over 80% of social browsing happens on phones. Preview your image on a small screen before publishing.
Feed square: 1080×1080 px (1:1). Portrait feed: 1080×1350 px (4:5) — often the best use of feed space. Stories and Reels cover: 1080×1920 px (9:16). Profile photo: 320×320 px displayed, upload at least 400×400.
Keep logos and text inside the center 80% of Stories and Reels. UI elements cover the top and bottom edges.
TikTok and YouTube
TikTok video and cover: 1080×1920 px (9:16). YouTube thumbnail: 1280×720 px (16:9) — minimum width 640 px. YouTube channel banner: 2560×1440 px with safe text area roughly 1546×423 px on desktop.
YouTube thumbnails compete in search — use high contrast, large readable text (3–5 words max), and faces when relevant. Test readability at phone size.
X, Facebook, and LinkedIn
X (Twitter) in-stream image: 1600×900 px (16:9) or 1200×675 px. Facebook feed link/image: 1200×630 px. LinkedIn post image: 1200×627 px. LinkedIn article cover: 1920×1080 px.
LinkedIn audiences tolerate longer text on images than Instagram. Keep B2B graphics clean and legible — avoid cluttered infographics on mobile.
File format and compression tips
Use JPEG for photos and PNG for graphics with text or transparency. WebP is supported on many platforms and reduces file size. Avoid re-saving screenshots multiple times — quality degrades quickly.
Resize before upload rather than relying on platform compression alone. Our image resizer processes files in your browser so originals never leave your device.
