try to add this (possibly best via a ‘custom CSS’ plugin):
.page-id-2 .one-column #content { width: 800px; }
adjust the width to your liking…
.page-id-2
makes this specific to the linked page.

hmmm thanks but I’m new in wp and no idea how to add this. Where do I go for that?, and what width value should I enter?

Do I copy paste .page-id-2 .one-column #content { width: 800px; }
And where do I go to add it?
in the most basic way (but not recommended), add the suggested CSS at the end of style.css of your theme.

better, use one of the ‘custom CSS’ plugins https://wordpress.org/plugins/search.php?q=custom+css to add the CSS.
