Almost done growing: At age 18 you have likely reached your maximum height or close to it.

Maybe not: Boys usually have their main growth spurt in the mid-teens. Some may have a small second growth spurt after 18, but it depends on your family history. Most of the time your height velocity (how quickly you increase your height) is genetically determined. Eat healthy foods and exercise regularly, but you really can't change your height.
