What Are The Optimal Dimensions For The Cover Image

Cover image looks best if you use 2800x1200 size image (21:9 aspect ratio).

For best results try to keep the content within a centered box of 2800x560 (5:1 aspect ratio).

On mobile devices (where there's more vertical space) the image will be un-cropped and displayed at the original 21:9 aspect ratio. On larger screens you will see that the image is cropped to 5:1 aspect ratio (2800x560).

If you want to remove the cover image completely you can do that via the appearance tab at the top of your page:
