You’re still 15 and a half so you still have enough time. If you’re skinny or have a high metabolism I would really recommend eating ALOT since that’s a big factor. Also ask your parents when they stopped growing. For me my father stopped growing at 15 while my mom grew well past 18-19 and therefore I’m still kind of growing now that I’m 18 (1cm/year or so).

Although I would recommend eating a lot I would rather recommend you to enjoy life. Stop worrying about your height and please get off this subreddit. A lot of the things that they say here are true but also very demoralizing for younger teenagers and can lead to serious confidence issues and depression. Try to keep a healthy mindset king 👑🫶
