Social Media Image Sizes Guide: Aspect Ratios for Avatars, Posts, and Banners
Uploading images to social platforms is the best way to connect with your audience. But every platform has different size specifications. Uploading a landscape photo as an avatar results in your subject being cropped out, while uploading low-resolution graphics makes your profile look unprofessional.
To keep your social profiles crisp, you must crop and resize your assets to match standard platform parameters.
In this guide, we provide a complete cheat sheet of social media aspect ratios and image dimensions.

Best Practices for Cropping Social Graphics
- Center the focal point for avatars: Facebook, Twitter, and LinkedIn crop your square profile picture into a circle. Keep your logo or face centered inside the 1:1 frame to avoid edges getting cut.
- Observe vertical safe zones: For stories and shorts (9:16), avoid placing text overlays near the top 15% or bottom 15% where profile icons and comments widgets appear.
- Keep resolutions high: Standardize your crop to the exact dimensions listed in the table, preventing the platform's compression engine from stretching your image.
Using a local client-side tool like the Resizer & Cropper makes it simple to lock the exact aspect ratio (like 1:1, 16:9, or 9:16) and scale your files before publishing, guaranteeing your profiles look sharp and professional.
