Social Media Image Dimensions Guide 2026: Every Platform, Every Format
Social media platforms update their image dimensions constantly — what was correct in 2025 may already be outdated in 2026. Using the wrong image size results in awkward cropping, pixelated enlargements, or text getting cut off. This guide covers the current (mid-2026) image dimensions for every major platform, plus workflow tips for batch-resizing images to multiple platform sizes simultaneously.
Instagram's 2026 image specifications: Feed posts remain 1080x1080px (square), 1080x1350px (portrait, 4:5 ratio), and 1080x566px (landscape). Stories and Reels are 1080x1920px (9:16). Profile photos display at 320x320px but upload at 1080x1080px for quality. Instagram compresses all images — to minimize compression artifacts, upload at the exact recommended dimensions rather than relying on Instagram's resizing. For carousel posts, all images should have identical dimensions to avoid display inconsistency.
Facebook's image specs: Feed posts at 1200x630px (1.91:1) for link previews and 1080x1080px for square photos. Cover photos are 851x315px on desktop and 640x360px on mobile (upload at 1640x624px for crisp rendering on both). Group cover photos are 1640x856px. Event cover photos are 1920x1005px. Facebook's <a href="https://www.iamuu.com/en/blog/best-free-image-compression-tools-2026-comparison/">image compression</a> is aggressive — upload images in sRGB color space and avoid images with fine text, which becomes illegible after compression.
Twitter/X supports images up to 4096x4096px but displays them at 1600x900px (16:9) in the expanded view. In-feed previews are cropped to approximately 600x335px. For consistent tweet appearance, use 1600x900px. Profile photos display at 400x400px. Header images are 1500x500px. Twitter converts all uploaded images to JPEG, so avoid uploading PNG with transparency — the transparent areas become white or black.
LinkedIn's image dimensions: Post images work best at 1200x627px (1.91:1). Company page cover photos are 1128x191px (yes, that narrow strip). Personal background photos are 1584x396px. Article featured images should be 1200x644px. LinkedIn displays images at their uploaded resolution (within reason), so upload at the recommended dimensions for optimal quality.
For efficient multi-platform image preparation, batch resize your source image to each platform's dimensions using an online <a href="https://www.iamuu.com/en/blog/image-resize-guide-composition-techniques/">image resize</a>r. Upload the full-resolution original, create preset-sized copies for Instagram, Facebook, LinkedIn, Twitter, and Pinterest, and download all sizes in one batch. This saves 10-15 minutes per post compared to manually resizing in different tools. Visit www.iamuu.com/image/resize for a free batch image resizer with social media presets.
