Twitter Header tips

📐

Twitter/X profile header: 1500×500 px (3:1 ratio). The centre of the image is safe; the left and right edges may be cropped on some devices.

🎨

Keep important content (logo, text) in the centre third of the image. The left side is partially obscured by your profile picture on desktop.

💡

Twitter compresses all uploaded images. Use JPG at quality 90+ for headers — it keeps colours vivid after their re-compression.

📱

Preview your header on both desktop and mobile Twitter before publishing — the crop differs significantly between platforms.
