I grew after age 16 - a bit, probably 1/2 or 3/4 inch. I was mostly done at 14. I know several young woman who grew in college. One added only 1/2 inch but the others grew 2 inches or more! The 2 that grew more than 2 inches were seriously late hitting puberty. They both looked like skinny little kids until 17. Those that grew 2 inches were more typical age at puberty and had normal to stocky builds. My dd is 5'3 a month shy of 12.
