Different layouts in different computers

I work on two computers, a MacBook Pro 13" and an iMac 21". When I switch to the MacBook Pro the layout it’s aligned to the left with a lot of space to the right. But in the iMac the layout is centered and the way I want it. When I preview the site in the iMac it looks the way it’s supposed to, when I preview the site in the MacBook it has the space I’m talking about. https://www.papel.studio
Anyone that can help?

Also, when I preview from the iMac, I resize the browser to see if the space will show up but it doesn’t.
