If you want to print on both sides of one sheet of paper, like a book, you need alternating margins.
If you want to print on just one side and leave the other empty, so all left hand pages stay empty when your report is bound, you need to use the documentclass option oneside.
Thank you very much ! Now it has the desired text width. My supervisor will be happy.
I think you are right about the alternating margins, I do want to print it two-sided. Luckily it still does that, but the effect is much less noticeable.
I'll post here if I encounter any additional problems. My thesis is pretty huge so.
Here is what it looks like now.
