Roller blind advice?

Question

I am thinking about buying a roller blind, as I have never had one of theses before. I was wondering is it possible to adjust it, or when you pull it down does it fit the window prefect?

Answer 1

They never seem to roll down level,always at a slant.

Answer 2

You just pull it down as far as you need it, the rest stays rolled up at the top.

Answer 3

They are diy adjustable, or some firms make to measure. Getting the width right is the main problem - length you just pull down as far as you need.
