Why is my footer a smaller size on a specific page?

On my new WordPress site, Team Origami, there is one specific page where the footer is narrow for some reason and I can’t figure out why.

Here is the page:
https://teamorigami.com/the-history-of-origami/

Other similar pages, like this one, are the normal size:
https://teamorigami.com/about-us/

You can see the difference by going to the very bottom of each of those pages. If someone could tell me why it is doing that and how I can fix it, that would be great. Thank you!
