It is a personal thing. The best way to find out how much you need is to get at least 8 hours for a few nights then start going to bed at the same time everynight when you can wake up on your own. After a few days it should become evident how much your body needs.

You sleep in 90 minute sleep cycles. They begin and end with REM sleep. That's dream sleep.
Try to get 5 uninterrupted sleep cycles. That's 7.5 hours. If you notice, if you wake up in the night to pee, it will always be between sleep cycles.
If you get up in the middle of a sleep cycle, you'll be tired and crabby all day. If you have to go short on sleep, sleep 6 hours. That's 4 cycles. If you have to, go 4.5 cycles, which is 3 cycles. But catch up with 5 or 6 cycles the next night.
Works great! If you go to bed 8 hours before you need to get up, that gives you a half an hour to fall asleep and then 5 sleep cycles.

From age 13-22, the optimum amount of sleep per night is 9 hours, 15 minutes.
From age 22-up, between 8 - 9 hours is best.

At least 2 REM cycles. Thats about 3 hours. Thats the bare minimum to get on a regular basis. Anything extra is gravy, but 4 REM cycles will make you feel better. That about 6 hours. More if you're still growing.

One "should" aim to feel rested after a nite sleep. We all observe that we tend to be less tired when we wake up. But it is not clear that the more time spent asleep, the more rested one feels upon awakening (alas!).
To oversimplify, our sleep architecture consists of cycles of "deep" non-REM sleep and REM sleep. The trick to waking up feeling rested is thus to ensure that you don't wake up during that period of "deep" sleep, which is well, tricky. The duration of this "deep sleep" is variable; however, it is at least 90 minutes and gets shorter with each repeating cycle. Thus, the more time we spend asleep, the shorter the "deep sleep" stage, the more likely we are to wake up when we are not in "deep" sleep, and the more rested we feel upon awakening.
Similarly, for a nap to be effective , it should be be less than 30min, afterwhich, our normal sleep architecure is such that we move to "deep sleep", awakening from which is rather difficult and unpleasant.
