It's possible but less likely to grow a full 9 cm (about 3.5 inches) after 17, as most growth finishes by then, but some individuals, especially males or "late bloomers," can still gain several centimeters if their growth plates are open, influenced by genetics, nutrition, sleep, and overall health, with some rare medical conditions allowing growth into the early 20s.
It is possible but not guaranteed. At 17, some males still have open growth plates and can grow several centimeters more. If growth plates have closed, further natural height increase is unlikely.
It is completely possible for a person to grow 2 more inches after 17. Every person grows at a different rate, and have growth spurts anywhere in the teen years. The male height growth tends to completely stop around the age of 24 although slows down long before that while the female stops growing around the age of 21.
Boys tend to have their growth spurt about two years later than girls. Peak growth for boys is right before spermarche (sperm in seminal fluid) and is about 9 centimeters/year.
Based on CDC data, the average height for 17-year-old boys is around 5 feet 9 inches (175 centimeters). However, keep in mind that there is a wide range of normal growth, and individual growth patterns can vary.
Generally, speaking, most boys stop growing between the ages of 16 and 18. Note that some kids will stop growing earlier and others may keep growing a few years more.
The analysis revealed that taller individuals had shorter lifespans compared with their shorter peers (Table 1). In individuals who lived for at least 50 years, longevity was inversely correlated with adult height in men (r = –0.27, p < 0.001) and women (r = –0.25, p < 0.001).
Scientists estimate that about 80 percent of an individual's height is determined by the DNA sequence variations they have inherited, but which genes these changes are in and what they do to affect height are only partially understood.
Here are the most common age ranges when you might notice rapid growth: Infancy: Babies grow the fastest during their first year. They can grow up to 10 inches and triple their birth weight in the first 12 months. Toddlerhood (ages 1 to 3): Growth slows a little after infancy, but toddlers still grow.
The upper age limit for starting GH therapy is generally determined by the status of the growth plates (epiphyses) in the bones. Once these plates close—typically around age 14 in girls and 16 in boys—further height increase is not possible.
Add the mother's height to the father's height in either inches or centimeters. Add 5 inches (13 centimeters) for boys or subtract 5 inches (13 centimeters) for girls. Divide by 2.
If there are no signs of puberty by 14 years, then puberty is delayed and further assessment is indicated. From 14-17 years most boys will be either 'In puberty' or 'Completing puberty'. After 17 years boys will usually be 'Completing puberty'.
A growth spurt is a short period of rapid growth in which your child will get taller and gain weight. Growth spurts are a normal part of child development and will happen throughout your child's life until they reach physical maturity – usually between 16 and 20 for girls and 17 and 20 for boys.
Once growth plates close, reopening them naturally is highly unlikely. However, some individuals consider advanced treatments, such as height-increasing surgeries or hormonal therapies. It's essential to consult a specialist for accurate advice tailored to your body type and health.
Boys tend to show the first physical changes of puberty between the ages of 10 and 16. They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
Peak height velocity — your child's biggest, fastest growth spurt — typically lasts 24 to 36 months. And while it's difficult to say just how much your child will grow during this time, you can count on most of it happening, for girls, between 10 and 14 years, and, for boys, between 12 and 16 years.
11 Foods That Can Promote Height Increase
From age 1 and puberty, most people grow 2 inches taller every year. After hitting puberty, it increases at the rate of 4 per cent till you reach the age of 18 years. Growth after this period slows down or completely stops.
The best predictor of a child's height is their parents' height or, more specifically, the mid-parental height. The mid-parental height is calculated by adding the mother's and father's height, adding 13 cm (5 inches) for boys or subtracting 13 cm (5 inches) for girls, and then finally dividing by 2.
Genetics is the main contributor to height, but nutrition can play a small role. Some research indicates that certain foods can boost height, especially when an infant or child is malnourished and dealing with growth stunting. Some key nutrients that benefit height include protein, zinc, and vitamin D.
They knew that about 80 to 90 percent of height is shaped by genetics, with environmental factors playing a smaller role. And by studying family histories, they'd identified hundreds of monogenic traits: single, rare genetic variants that can have large effects on height.
Women who weighed less at age 20 and put on less weight as they aged were more likely to live longer than heavier women. Height played a major factor: the study found women who were taller than 5 feet 9 inches were 31% more likely to live into their 90s than women who were less than 5 feet 3 inches.
A health risk is the chance or likelihood that something will harm or otherwise affect your health. Risk doesn't mean that something bad will definitely happen. It's just a possibility. Several characteristics, called risk factors, affect whether your health risks are high or low.
