I would personally recommend 7x50 binoculars. You are trying to collect as much light as possible. The ideal binocular has it's objective lens 7x the magnification.
Obviously a larger objective lens would allow for a greater magnification. But the most common and reasonably priced are the 7x50.

It all depends on the budget and what you propose to see. Doesn't matter whether you are a teenager or not.
A standard binoculars would be a 7x50. The 7 stands for magnification while the 50 is the diameter of the objective lens in millimeters. There are two types of binoculars. The Porro prism and the roof prism. The roof prism is what you see for sports and general binoculars. The prro prism is generally used for astronomical purposes because they are easy to align and thus a little cheaper.
If you are a serious observer, then it would be better to invest in something like a 10x50 or bigger. Of course, once it gets to that you will need a tripod. If you want to spot nebulae and other dimmer messier objects, you ned more powerful ones like a 20x80 or larger.
Check out www.telescope.com or www.celestron.com or www.telescopes.com. There are more sites out there which will give you al lthe help you need.
Happy gazing!!!!! :)

I would say a pair of 10X50 would be ideal for general stargazing, but there are sites on the web which can answer these sort of questions better than me. You do not need to concern yourself too much with the exit pupil as this is a standard 7mm for most.
Try www.astronomy.com or www.skyandtelescope.com which will advise you of all the advantages/disadvantages of the various types.
I can personally recommend Celestron if you are on a tight budget, or Pentax which are a bit more expensive, but I definitely reckon 10x50 (10x magnification and 50mm objectives) are excellent. Any bigger and you will need a sturdy tripod to hold them still and prevent arm fatigue.

For a teenager the 7 mm exit pupil of 7x50 is fine. 10x50 will give you a smaller field probably.
Get the best quality that you can afford!

The usual recommendation is 7X50, but I have 10X50. To get the full benefit 7X50 you need a really dark sky and young eyes, and at 10 power you really need a tripod to hold 10X50s still enough. So there are trade offs, as in all choices.
