Even if you hit puberty late, you’re unlikely to grow significantly after the ages of 18 to 20 . Most boys reach their peak height around the age of 16.
Thereof, can you get a growth spurt in your 20s?
ANSWER: Most males stop growing – significantly, anyway – around age 18, but “most” does not mean “all.” Men and women can continue to grow well into their 20s. Continued growth depends on whether bones have fused – become entirely bone.
Considering this, is it possible to grow height after 21?
No, an adult cannot increase their height after the growth plates close. However, there are plenty of ways a person can improve their posture to look taller. Also, a person can take preventative measures against height loss as they age.
