Before you dive into the nitty-gritty details, here are some fast facts on when boys stop growing:<\/p>\n
- \n
- At what age do boys stop growing? The average boy reaches his full height by age 16 years old (although some continue to grow, albeit more slowly, until 21).<\/li>\n
- Puberty is the most significant factor when a male starts to grow. Expect significant growth spurts beginning at ages 12\u201315.<\/li>\n
- Several factors impact height, the largest of which is genetics. However, several health conditions can prevent a boy from gaining height or too much height.<\/li>\n
- Boys generally grow faster than girls in childhood and tend to stop growing later. Girls reach their full height at 14 or 15, while boys typically stop growing at 16.<\/li>\n
