Can I grow a inch?

I am an 18 year old male( turning 19 in 2 months) and I have grown 3/4 of an inch in the past year. However my growth as always kind of been steady, I never really had a huge growth spurt( peak was 2 inches in one year 14-15) At 5'8 3/8 at just 15 my growth pattern told me that I was going to be 5'11, well it never happened( Dad is 5'11.3 mom 5-4) Both of my grandpas were 6 feet). when I turned 17 I had grown only to 5 foot 9. I Thought I was done growing( even though I looked like a 14 year old without any hair on my face) Well when I turned 18 during last summer, all of a sudden my voice started cracking, started growing light facial hair, fine chest hairspimples all over the place and grew .70 of an inch to my current height of 5'9.7 I still have very oily skin and my voice still breaks occasinaly and my facial hair grows very slo?w. In your opinion how much height can you think I can get

Can I grow a inch?

Yes, I think it's highly possible that you could grow an inch, however, it probably won't be within a short amount of time, since you seem to have passed up your rapid growth spurt. However, it is still quite possible for you to have grown an inch or two more by your 21st birthday because while your growth is starting to "plateau" or "level off," it is doing so in a curved manner like a pool gradually dropping off to 8 feet. So while you may not gain that inch by the end of this year, it may very well come in over the next two or three years.
