No one can predict your height. The average age men stop growing is about 21. Some can still grow until they're 25, some stop growing at 16. However, you don't see too many growth spurts in your 20s. How much have you grown in the past few years? If you haven't really grown that many inches the past few years, chances are you're done growing.
If you're insecure about your height, don't be. You're about the average height of an American male.
Unlike me, I'm 5'6 but I've learned to embrace my shortness and I make up for it in different areas.
