About the X (Twitter) Header Resizer
The header (banner) on X, formerly Twitter, is 1500×500 pixels — a wide 3:1 strip. This tool scales your image to fill that banner and center-crops the overflow so nothing is stretched. Keep key elements in the center: your avatar covers the lower-left corner and buttons sit at the lower-right, and on mobile the bottom strip is partly hidden.
Frequently asked questions
What size is an X / Twitter header?
1500×500 pixels (3:1). This tool outputs exactly that, center-cropped so it fills the banner cleanly.
What part of my header gets covered?
Your profile photo overlaps the lower-left, action buttons sit lower-right, and mobile trims the bottom — so keep important content centered and away from the edges.
