Height Calculator

Based on a linear regression study, this free growth calculator estimates a child's growth as an adult in the future. It can also be converted between several height units.

What will my height be?

A mix of genetics and environmental factors determines a child’s height. The exact contribution of these two elements is difficult to determine. According to several analyses, heredity accounts for 60–80% of the variance.

In most scenarios, experts determine the child's height by the height of their parents, which is subject to regression to the average value. Parents who are very tall or short are likely to have children who are taller or shorter than average. However, children are expected to be closer to average height than their parents.

Nutrition, general health, athletic activities, and the health and age of the mother during pregnancy are all significant factors that influence a child’s adult height.

In infancy and childhood, we grow the fastest. The growth rate slows dramatically from birth to around the age of two, then slows again. During puberty, a person's growth rate reaches a new maximum, gradually decreasing to zero after puberty. This is often known as the "pubescent growth spurt." At roughly 15 and 18 years of age, female and male growth slows to a halt.

In certain situations, a person’s height deteriorates in middle age. Stature deterioration is almost ubiquitous in the elderly. This is caused by a loss of intervertebral disc height and changes caused by degenerative diseases.

Estimating the adult height of a kid

Various methods for predicting a child’s adult height have been devised, some of which are more reliable than others. However, height projection is not an exact science, no matter how practical the approach is. A child’s height may differ significantly from what is expected.

Skeletal maturity technique, bone age

Bone age is a more accurate way of predicting height than the other procedures mentioned below. The Greulich-Pyle technique, which uses radiographs of the left hand and wrist to determine bone age, is one strategy. This approach compares the patient’s radiograph to the closest standard radiograph in the Greulich-Pyle atlas, a database of bone age information.

You can predict growth by using the percentage of growth development based on the child’s bone age, height, and data from the atlas. However, the information in the atlas has data on Caucasian children gathered between 1931 and 1942, which may restrict how well the Greulich-Pyle approach can present youngsters.

The Khamis-Roche technique

The Khamis-Roche approach is one of the most accurate height prediction models that does not involve bone age measurements. Instead, it is calculated based on the child's height and weight and the parents' average height. We use this strategy in the first calculator. It is most appropriate for Caucasian children aged 4 to 9 who are free of any growth-related illness or condition.

Making use of growth charts

The CDC US growth charts provide essential information for assessing a child’s growth status. The percentile curves within those growth charts depict the distribution of particular body measures among kids in the United States. Sixteen charts offer data that may be compared to a child’s progress.

You can compare your child's expected height, weight, and head circumference to those of their age and gender. Children’s developmental curves are often relatively consistent. So you can use the charts to approximate a child’s future height as an adult.

Simplistic Techniques

There are also some simple but less accurate procedures available. Add 2.5 inches (7.6 cm) to the average height of the boy’s parents or subtract 2.5 inches (7.6 cm) from the parents' average height for the girl. We use this strategy in the second calculator above.

Another quick method uses the child's height at age 2 for a boy or 18 months for a girl. By doubling this parameter, you can approximate their future adult height.

How can I get taller?

Height is primarily (60-80%) influenced by heredity. As previously said, tall parents have taller kids. In contrast, children of short parents are more likely to have shorter children, with the child's being closer to standard height than their parents.

After a teenage growth spurt, no one usually grows any further. Girls generally stop growing by 15, while boys stop around 18.

Several environmental factors might influence a child’s height. Some may be under the child’s control, while others may not. For example, the mother’s nutrition and health throughout pregnancy can affect the height of the unborn child. Both food and activity after birth may influence height as well.

The following are some suggestions for providing the most significant circumstances for your body to grow:

  • Consume more fresh fruits, veggies, whole wheat grains, proteins, and dairy products.
  • Avoid processed sugars, trans fats, saturated fats, and sodium-rich meals.
  • Regular workouts or other physical activities help build bones and muscles, maintain a healthy body weight, and lower the risk of illnesses like osteoporosis and other health problems.
  • Take care of your posture. Aside from making you appear shorter because of poor posture, it can also influence your height over time if your back curves fit a habitual slouching position.
  • Get good sleep regularly. A person's age determines the amount of sleep they should get. Younger children need more sleep than adults. Sleep deprivation regularly during adolescence can have a long-term impact on growth. Human growth hormone, a growth-promoting hormone, is secreted while you sleep.
  • A disease or condition may prevent your growth in rare situations, and a physician may help you.

A person usually reaches maximum growth after entering puberty. A person who has undergone puberty will generally maintain their height into adulthood.
