What is the Khamis calculator?
According to Dr. Alex Roche, adult height can be predicted using a simple mathematical equation using parent height, current child height, and current child weight.
History of the Khamis Calculator
Dr. Roche worked with researchers on the Fels Longitudinal Study collecting information for personal study and contracted research. The focus of the study was to find predictors that could give some insight into growth rates, final height and final weight in adulthood. After years of research, four factors that contributed to growth were revealed:
Limitations to the Khamis Calculator
The Fels Longitudinal Study, which is the research on which the mathematical equations were based, was primarily a Caucasian study. Since the study lacked participation from other races, the Khamis calculator equations are based solely on Caucasian children born to two Caucasian parents.
How to figure out how tall a child will be?
So, to estimate how tall a child will be, first, select their biological sex (gender). Then enter their current age: type in whole years manually and select the number of months by rounding to the nearest whole month. For a newborn, enter zeroes in both years and months. Enter their height in feet and inches or in cm or meters.
What are the factors that affect height?
The single most significant factor affecting the adult height of a child is its genetics. However, a child may not reach its full genetically-determined height potential due to other factors at play, such as: 1 Nutrition. Inadequate nutrition, both in terms of total calories consumed and in terms of making sure all macro and micro nutrients are present in the diet, can certainly hinder growth. See our daily calories calculator. 2 Hormones. Issues with hormone levels, especially growth hormone or thyroid hormones can impact the end height in both directions. 3 Diseases. Health issues, for example coeliac disease or early arthritis play a negative role 4 Genetic conditions. Some specific genetic conditions such as Marfan's syndrome or Down's syndrome have an effect on growth.

How is height determined?
The height of a person is determined by a combination of genetics and environmental factors. The precise contribution from these two factors is complex. Some studies suggest that genetics contributes 60%-80%. Normally, a child's height is based on parental heights subject to regression toward the mean. This means that very tall or short parents are ...

What is growth chart?
Growth charts represent a series of percentile curves which depict the healthy expected rates of mass for heights, or other specific body measurements. These are used to track healthy infancy, as well as childhood growth in order to screen for potential risk factors, such as limited growth, or excessive growth, or obesity. Two leading growth charts include the World Health Organization’s WHO Growth Standards chart and the CDC growth charts. The former is used mainly to track the growth of infants, and the latter is used for children ages two and over. Although the results derived from these charts form part of the measurement, these are not used solely to make diagnoses and the information would be incorporated with other variables to identify potential warning signs. If you have any concerns about the rate of growth of your child, it is best to seek medical advice.
Can you predict height in adulthood?
There is no tool proven to predict height in adulthood with 100% accuracy. There are several factors that may influence height reached in adulthood, which makes prediction relatively difficult. However, there are several formulae available that can serve as fair estimates of future height.
