Mostly: Men reach adult height around 17 years, give a centimeter. So you can still be equal to your brother, otherwise, plan to wear a raised heel shoe!

Maybe: Your projected height from parental input is 161+185/2 plus 5 cm which would be 178. This genetic projection is a rough one at best, but was derived from thousands of cases. Most males stop growing at 16-17 while those who transition through puberty slower finish later.An x-ray of your wrist/hand could be examined for open growth centers.If present you will grow taller, if not you are done.
