The manual that comes with your machine should have a reference list for matching fabric with needles. If you don't have a manual, look online, there are lots of free manuals online.
I know why you use different size needles, I just wonder why you all seem to think you have to use new needles
so often . I've heard comments like I change needles with every new project I start. Seems like a waste to me, especially if you are using the same fabrics. I don't mean changing when you get a burr or bent, etc. I mean just changing so often when there doesn'T seem to be anything wrong with the needle that is in there.
