Growth is mainly determined by genetics, though factors like nutrition and sleep play a role.
Once the growth plates in your bones fuse, further height increase becomes unlikely.
Growth plates determine height potential
Growth plates are cartilage layers at the ends of long bones.
Once these plates fuse after puberty, the bones can no longer grow in length, marking the end of height increase.

Genetics play the biggest role in height
Around 80% of a person’s height is determined by genetics.
A simple formula to estimate height is averaging both parents’ heights and adding 2.5 inches for boys.
Nutrition is a key factor in growth
Lack of essential nutrients, particularly protein, vitamins, and minerals, can stunt growth.
A balanced diet during childhood and adolescence is crucial for reaching full height potential.

Sleep impacts growth hormone production
During sleep, the body produces growth hormone, which is essential for bone development.
Consistently missing out on sleep could potentially affect height growth.
Some medications may temporarily slow growth
Certain stimulant medications used to treat ADHD have been linked to temporary growth delays, though studies show most children catch up in height over time.
Health conditions can stunt growth
Genetic disorders like Turner syndrome, Down syndrome, and thyroid diseases can affect normal growth patterns and limit height.

Posture can make you look taller
Although improving posture won’t make bones grow longer, standing up straight, stretching, and strengthening core muscles can maximize your apparent height.
Height fluctuates throughout the day
Your spine compresses slightly over the course of the day, causing a height loss of about 0.3 inches.
If you measure yourself in the morning, you may appear taller than in the evening.
Doctors can track growth patterns
Regular pediatric checkups help track a child’s growth over time.

Most guys stop growing at this age
While puberty can start as early as age nine or as late as 15, most boys experience their biggest growth spurt between 12 and 15.
By the time they reach 18, their height is close to its final measurement.
Late bloomers might grow into their early 20s
Some boys enter puberty later than others, which can slightly extend their growth phase.
