Huge padding under certain pages

Hello,

I’m pretty much a wordpress beginner and really still figuring most things out and I’ve run into this weird and annoying problem.

The padding under my navigation menu is different and too big on most pages!

On the “home” and “veilingen” page it is all good. Then on all the other pages there is too much padding and I’m not sure how to get rid of it. Take the last one “Over ons” for example.

Any thoughts would be greatly appreciated.

Cheers
