Right column margins are massive

Recently I’ve been wanting to use multiple columns to layout a sort of dashboard for my docs. However when I do a column it creates this huge margin on the ride side of the page.

I did a little digging and found that the div for the columns uses width-narrow. However they seem to have added a wide-width variable as well since I can replace it and it will make equal margins on the left and right side. So I don’t understand why would they not make it default to equal margins on each side? It makes it really cramped when using columns. I’ll put this in suggestions so that way maybe someone from the development could look into this.
