To change your background profile image, go to your profile, click the Change background button on the upper right, and upload any JPG or PNG image over 1920x640px.
How to get a thinner profile image
Users often ask us how to change the profile background image to something that is thin, as uploading a 1920x640px image causes your portfolio to be pushed down the page.
ArtStation is a responsive site - meaning that it is viewed on a variety of devices, from tablets to huge monitors with different aspect ratios. This makes our handling of images more complex.
The minimum size required to make your profile header image look good (no upsizing) is 640px height. As long as you upload anything larger than 1920x640, it will look good and will responsively resize the image, retaining the correct aspect ratio.
To get a thinner image, upload something with a larger aspect ratio. E.g. 2560x640px.
