Twitter / X Banner Sizer

Twitter / X banner spec

• Size: 1500 × 500 pixels (3:1 ratio)
• Max file size: 5 MB (PNG, JPG, WebP)
• Profile pic overlay: ~200px wide circle, centered at left edge ~145px in, ~425px from the top — covers the bottom-left of the banner
• Mobile crop: Mobile shows roughly the middle 50% of the banner. Outer edges get cropped

What works in 1500×500

• Centered subject or text — survives both mobile crop and profile pic overlay
• Gradient background — fills the whole banner without competing with the avatar
• Single dominant color band — works as a clean stage for your @-handle
• Avoid faces or critical text in the bottom-left or the outer 25% on each side
