New Twitter Header Photo
Twitter has just introduced a new profile layout along with header photos for accounts, presumably today on 3-27-2014. Rather than you spending the time finding all the right sizes to make your awesome header images, I have put together a rough template for you to use for free! Use the template for Free and Commercial layouts all you like!

The image seems to be responsive according to browser size, so it might not look exact depending on your screen and window size. This should get you off to a great start though! I left plenty of room to adjust boundaries dependent on your targeted viewing size. Free files below!
