Best way to scale from desktop to 1920px?

My site looks great on Desktop and 1440px but gets very small on 1920px and up.
What’s the best approach to make it match without having to edit size on everything? When I zoom in 150% im on Chrome it looks perfect.

@Crunchii use “em” at the place of pixel “PX”. if you can’t do this so connect me on upwork. Moheen A. - Webflow website Development - Upwork Freelancer from Abbottabad, Pakistan
