The only way you can actually get taller is by natural growth. No stretching or excercising will make you grow. The one key factor in whether or not you will be tall is genetics. Are your parents tall? If they are, you will probably be tall too. Like i said before, nothing can make you grow; however, getting regular amounts of sleep (8-10 hours) each night and eating healthy food can make it easier for your body to grow.
I use to sleep a lot ( ~9 hours every night) and drink a lot of milk and I'm 187cm (i just turned 14). I actually think that cam96 is right. If you have tall parents, you'll be tall too.
Your genetics detemine how long you can grow max.
Only thing is, you will only grow this long if you eat enough and healthy and have enough sleep!
If your genetics determine you will never be very long, then you are unlucky. But try to live as healthy as possible to grow alot!
