How fast does the penis grow per year?
The rate at which your penis grows depends on what point you are in your development. See the discussion on penis growth for details. In stage 3 your penis will grow more quickly in length, but in stage 4 it will increase in circumference. Most of the fast growth occurs about the same time your body speeds up its growth. However, I can’t tell you exactly how fast any one person’s penis will grow in a year, just as I can’t tell you how fast you will grow in the upcoming year. If you are just starting your growth spurt, I can tell you that you will grow faster than you have been in the past, typically twice as fast as you grew in the past, but I can’t say the exact rate or amount for any one person. To estimate what stage of development you are in, see the Tanner Stage Calculator for Boys.
