New curtains

I finally got some curtains for my room!! BUT, I ordered the 84" standard length drapes, and they are too short. So, I sent them back and got the next size up: 96". So now I have a problem. Do I hang the curtains at the standard "several" inches above my window and let the curtains fold over the carpet?? OR do I hang them where they will be just at the floor line, with the rod very near the ceiling?? Is it weird that I am even having this problem?? Is it the my ceiling is a weird height??
