Figure 1: How your twitter header will look like in your profile
Figure 2: The top and bottom portion of the header will be cut off
Twitter will replace the top and bottom portion of your header image with the white border seen in Figure 1. Thus, the ideal Twitter header dimensions would be 1500 x 421 px. This size would allow you to comfortably design your header without worrying about any parts getting cut off. (Figure 2)
The last thing to remember is the area where your profile picture would be. Avoid having images/text in that area as it would be covered by your profile photo.

Besides uploading just standard headers for Twitter, many people have recently started to use a white header — making its popularity skyrocket.
Minimalistic in design, white Twitter headers blend in perfectly with Twitter’s light mode and give off a serene and aesthetically-pleasing vibe.
Generally, people use small graphic overlays, coupled with things like text messages and white background as their Twitter header image.
