Stop featured images from being cropped

I am trying to update an existing site with the Newspaper X theme. However, when I am adding new posts for my portfolio, it is automatically cropping the artwork. As you can see in the screenshot (the new post is on the left, the old format is on the right), this is not acceptable for displaying artwork. I need the images to not be cropped. They are also cropped on the single post page itself, so you can never see the full image. I’m sure there is a way to change this, but I can’t figure out how.

Hello there,

I hope you are doing well today.

You will have to edit the post thumbnails. Have a look at this article that explains how to do so:
