The most common mistake with Twitter/X headers isn’t the overall size — it’s not accounting for the avatar overlap in the bottom-left corner. Here’s how to design a header that looks perfect on both desktop and mobile.

This is the current recommended size from X/Twitter for 2026.
The Hidden Problem: Avatar Overlap on Desktop
Here’s what Twitter doesn’t tell you clearly: your profile avatar overlaps the bottom-left corner of your header on desktop:
- The avatar covers approximately 200×200 pixels in the bottom-left
- If you put your logo, text, or key design elements there, they’ll be partially blocked
- This ruins what could have been a great header design
What makes this even trickier is that mobile and desktop show different portions of your header:
- On desktop, the entire 1500×500 is visible
- On mobile, the header gets cropped vertically, and the avatar is positioned differently
What is the “Safe Zone” for Twitter Headers?
To ensure your important content is visible on both desktop and mobile, follow these safe zone guidelines:
- Keep all key content (logos, text) at least 200px from the left edge
- Keep all key content at least 100px from the bottom edge
- Place your most important design elements in the center-right area of the header
- This leaves the bottom-left clear for the profile avatar overlap

Frequently Asked Questions
What is the correct Twitter header size for 2026?
The recommended size is still 1500 × 500 pixels (3:1 aspect ratio). X/Twitter hasn’t changed this specification in years, and it’s still the standard for 2026.
Why does Twitter crop my header image?
Twitter crops headers to fit different screen sizes. If you upload an image that’s not exactly 1500×500 or the wrong aspect ratio, it will automatically crop it, which can cut off important content.
How do I stop my avatar from covering my Twitter header?
The solution is simple: don’t put important content in the bottom-left 200×200 pixel area. Our tool shows you exactly where the avatar will be so you can design around it.
Does the Twitter avatar overlap on mobile too?
No, the avatar is positioned differently on mobile and doesn’t overlap the header the same way it does on desktop. By designing for the desktop overlap, your header will look good on both platforms.
