Frequently Asked Questions
What is the best image size for Twitter/X posts?
Twitter recommends 1600x900 pixels (16:9 ratio) for single-image tweets that display fully without cropping. For two images, use 700x800 each. Twitter supports up to 5MB for photos and 15MB for GIFs. Images wider than 4096 pixels are automatically downsized by the platform.
What are the Twitter/X header dimensions?
Twitter headers should be 1500x500 pixels (3:1 ratio). Keep important content centered because the edges may be cropped on different devices and screen sizes. The profile photo overlaps the lower-left area of the header on desktop, so avoid placing key elements there.
How does Twitter crop images in the timeline?
Twitter uses an AI-based smart crop algorithm that attempts to find the most visually interesting focal point. To avoid unexpected cropping, use the recommended 16:9 aspect ratio for single images. Center your subject and keep important elements away from edges to ensure they remain visible after auto-cropping.
