If you have a Twitter account and spend much time on it every day, then you get to know better about the importance of a Twitter Header. This prime space is good to show off your personality or market your brand because it is almost the first thing that people will see when they visit your profile.

Before picking up a charming image, you should have a clear view of the requirements for a Twitter Header. If the image you want to use is a little bit big or small, don't worry. You can use tools like Vance AI Image Resizer to resize an image.

Twitter Header Requirements

According to Twitter's recommended guidelines, the header image dimensions are 1,500px by 1,500px, which has an aspect ratio of 3:1. JPG, GIF, or PNG are supported but not animated GIFs. Besides, the profile and banner image file size should be less than 2MB. If you worry that the header will be cropped for different screen resolutions or for your profile image, it is helpful to leave ample space on the bottom left corner and leave some empty space at the top and bottom of your header.
