What is the best image size for X (Twitter) posts?

All networks are different and follow different rules when it comes to images sizes.

To prevent your images from appearing pixelated or not at all you should make sure to consider each network's individual requirements for image sizes. Images that are too large or too small might appear blurry or will not be posted at all.
