This programme makes an estimate of your height once you are fully grown. It is based upon research of child growth conducted in the United Kingdom. From the averages of this data it is assumed that males reach their full height at age 18 and fmales at age 16. But, as with all averages, this is an estimate only - everybody grows at different rates and can start or stop growing late or early. The final result hence has a variance of + or - 5 cm's.
The best indicator for estimating your height when fully grown, is to just look at your parents!
You will grow to be about centimetres tall.
When you get an answer equal to your original height, you are already full grown. But remember, this is only an estimate. Everybody grows at different rates, so this estimate can have an error of about maximal 5 cm's.
This estimate of your full grown height is based upon research of child growth conducted in the United Kingdom. It is known that every human grows in about the same way. Measuring a great amount of boys and grls yielded averages of growth rate, height and full grown height. In the table below you can see the resulting chart which depicts how a human grows.
In their first few years, childeren grow rapidly. At age 6 their growth becomes less and starts to stabilise at about 7 cm's per year. Until this stage males and fmales are equal in height and posture.
After this relatively long stage of stable growth a growth spurt sets in, developing the human from a child into an adult. This stage for womon peaks at age 12, 2 years earlier than for men. During this stage heightened hormone and activity levels promote a faster growth and development of secondary sezual characteristics. Because this stage starts two years earlier for womon, grls aged 12 or 13 years are usually taller than their male contemporaries. After that the males catch up and pass them again.
Fmales stop growing at about age 16, males about at age 18. Diseases, nutrition and stress can cause large variances in this pattern though, extending it by as much as 2 years, or bringing it to an early stop. Hence estimates based on this knowledge can be erroneous and vary by as much as + or - 5 cm's.
The programme above uses the data from this research and your position on the growth chart to make a prediction of your final height. Credits for making the programme go to Science North.
