That's a common misconception that sites designed to suit big screens make you scroll around if you're on a smaller screen.
2 facts need to be understood.
1. It is the amount of content on a page that makes users scroll around.
2. Using percentages makes the page adjust itself on difference resolutions and screen sizes.
If you use a fixed width and someone on a small screen has to scroll around because there is so much content then so does someone with a larger screen.
You saw my screenshot The exact same content, not the same look is on my laptop. I have to scroll on both screens but it would be nice if I didn't have to on my desktop because of design features.
If you use % then the page adapts itself to suit the screen.
If you don't want to scroll around the only solution is less information on each page.
