aspect ratios:

1. widest: 6.3:1

2. recommended by Game Jolt: 4:1

3. narrowest: 2.7:1

source: Game Jolt header requirements and guidelines

the rectangle in the middle is almost guaranteed to be seen (except the parts that are covered up by user info) but this only works if the header is not cropped.

heads up: after changing your header, Game Jolt crops it to 4:1 aspect ratio. you have to uncrop it on your 'Edit profile' page (but it's not possible in the mobile app, you have to do it on the website instead)

in this post you can download the header template in 2 colorways:

1. ½ grey

2. see-through
