Why Image Sizes Matter

Using the wrong image dimensions on social media leads to cropping, stretching, or blurry images. Each platform has specific requirements for different placements (profile, cover, feed, stories), and these change periodically as platforms update their layouts.

Properly sized images:

• Look sharper. No pixelation or upscaling artifacts.
• Load faster. Not oversized, so they download quickly on mobile.
• Display correctly. No unexpected cropping that cuts off important content.
• Improve engagement. Professional-looking visuals consistently outperform low-quality images in engagement metrics.

General Best Practices

• Use PNG for graphics with text, logos, and sharp edges. Use JPEG for photographs. Use WebP where supported for smaller file sizes.
• Design at 2x resolution for retina/high-DPI displays. A 1080x1080 feed post should be designed at 2160x2160 for crisp display on modern phones.
• Keep text within safe zones. Social media platforms crop images differently on mobile vs desktop. Keep critical text and logos away from edges.
• Optimize file sizes. Compress images without visible quality loss using tools like TinyPNG or ImageOptim. Aim for under 1MB for feed images.
• Test on mobile. Most social media consumption happens on phones. Always preview how your images look on a mobile screen.
• Use consistent branding. Maintain consistent colors, fonts, and visual style across all your social media images for brand recognition.

Platform-Specific Notes

LinkedIn Image Tips

LinkedIn crops cover images differently on mobile and desktop. Keep critical content centered. For feed posts, square images (1080x1080) tend to get more engagement than landscape. Document posts (PDFs displayed as carousels) should be 1080x1350 for vertical or 1080x1080 for square.

X / Twitter Image Tips

X displays images with up to a 2:1 aspect ratio in the feed without cropping. Vertical images taller than 3:4 will be cropped. When sharing multiple images, X uses specific grid layouts: 2 images side by side, 3 images with one large and two small, 4 images in a 2x2 grid.

Threads Image Tips

Threads supports images up to 4096 pixels on the longest side. Square and vertical images (4:5 ratio) tend to take up more screen real estate in the feed, which can improve engagement. The platform strips EXIF data from uploaded images.

Bluesky Image Tips

Bluesky has a strict 1MB file size limit for images uploaded via the API. Compress aggressively. The platform supports alt text, which is encouraged for accessibility. Up to 4 images can be attached to a single post.
