The dimensions are 520 x 260 pixels for the new Twitter Header image released by Twitter on Sept. 17th, 2012.

TIPS:
- Arrange any photos or text around the Profile photo, name, and bio information.
- Twitter adds a shade of grey to darken the image so if you’re looking for a true color, make your colors brighter to compensate.
- The text will be white with a slight black shadow so don’t make your Twitter header image too busy or the text will be unreadable.
Remember: Simplicity is key. The real power of twitter is the text content and information sharing. Don’t let the Twitter Header image over-power your message.
