Optimizing graphics for X timelines and profile headers
Complying with verified x twitter image size guidelines prevents timeline previews from cropping your photos unexpectedly. In-stream post images display well at a 16:9 ratio (1200x675 pixels), which allows mobile timeline feeds to show your visual content in full without requiring followers to tap to expand.
Profile header banners use an ultra-wide 3:1 ratio measuring 1500x500 pixels. To format diverse pictures for these proportions, our tool provides four fit modes. Crop fills the canvas completely from the center. Smart crop detects focal points to keep key subjects centered. Fit with color preserves your full photo within colored padding. Fit with blur nests your photo inside a soft blurred frame.
Sizes are recommendations and can change as network interfaces evolve. Platform names belong to their owners. Uploaded assets are handled securely in temporary storage and deleted automatically after about an hour with regular maintenance sweeps.
Everyday publishing tasks on X
Professionals and creators format 1500x500 header banners that account for the circular profile avatar overlay in the bottom-left corner on desktop browsers.
News organizations and bloggers convert landscape article illustrations into 1200x675 cards to ensure text and charts remain readable directly in timeline feeds.
Community managers format square 400x400 avatars that remain clear when masked into circular user icons.
Advice for sharp timeline presentation
Leave ample breathing room in the lower-left area of header banners so your circular profile avatar does not cover up important headlines or logos.
Stick to standard 16:9 ratios for single-image timeline posts so mobile apps display the full composition without awkward automatic cropping.
Upload high-quality source graphics up to 25 MB to ensure fine details survive platform re-encoding.
