Height Calculator


Table of Content


The height calculator predicts how tall am I and how tall will my son be as well as converts height into different units. Hence, evaluate the height for weight of your boy or girl child with the height predictor.

How Tall Will I Be?

Height is a measurement of vertical distance and shows how tall something or someone is. How tall am I going to be, in my case, it is the distance from the bottom of the feet to the top of the head. 

Whether you are short or tall is determined by your genes and the DNA combination of your parents. Apart from this, there is a height chart calculator which is very useful in estimating the height

How to Calculate Future Height?

Get the exact calculation by the future height calculator boys that take into service a couple of methods to figure out future height and clear your query about how to predict height. So look at the below formulas.

1. Mid-Parental Child Height Method:

The mid-parental height is the child's projected adult height based on the heights of the parents. If the father and mother's height is known then the prediction of the child’s height by the following equation can be made easy. 

(Mother’s Height + Father’s Height )/2

  • Boys Height = Mid-parental height + 2½ in (or 6.5 cm)
  • Girls Height = Mid-parental height - 2½ in (or 6.5 cm)

2. Khamis Roche Method:

It is considered one of the most accurate methods to figure out the height because it is pivoted on the child’s weight, stature, and parent's height. 

The child’s adult height is calculated through an accurate height calculator adults without needing to determine the skeletal age. The formula that is used by the child's height predictor is given below:

  • (Mother’s Height + Father’s Height )/2 + Child’s height 

3. Predict Child's Height Based On Puberty:

Height will be predicted by the height estimator based on the puberty stages so look at the below points to determine height in stages.

Step 1: Assess the Tanner Stage:

The Tanner stage categorizes sexual development into five stages. The stages are determined by evaluating secondary sexual characteristics.

Step 2: Determine the Corresponding Growth Chart:

Once the Tanner stage is determined, reference growth charts specific to that stage are used. These charts provide information on the average height patterns.

Step 3: Plot the Height Measurement:

Measure the individual's current height and plot it on the appropriate growth chart based on their Tanner stage. 

Step 4: Estimate Future Growth:

Based on the plotted height measurement, observe the projected height on the growth chart. The chart will provide an estimate of the individual's potential adult height, considering their current stage of puberty.

Working of Height Calculator:

Except for the height prediction calculator, there is no other such thing as a 100 percent accurate child height predictor. It functions well when you insert the below values in it. 


  • Choose a mode either imperial or metric 
  • Set the gender of the child and insert their age 
  • Put the height and weight of a child in the designated tool 
  • Mother's and father’s Height in ft/in
  • Tap on “Calculate”


Our height calculator facilitates the following results when you plug the above values in it. 

  • Future height of your child 
  • The margin of error for a child’s height prediction 
  • Step-by-step guide 

Factors Affecting the Height:

The child height calculator will estimate how tall the child will be and how tall will I be when grows into an adult. Genetics is the main factor that affects the child's height It's not wrong to say that the type of issues that you are facing from genetics causes to decrease the height. 

Some studies indicate there is about 60 to 80% role of genetics in height. The height of any person can be determined by knowing their combination of genetics and environmental factors. So look at these which are listed below:

  • Hormones and Socio-economic factors
  • Birth weight and gestational age
  • Health Issues / Diseases and Nutrition
  • Generic Conditions and Physical Activity and Exercise

Boys and Girls Height Chart:

Some boys reach their full adult before age 17 and some grow about 3 inches pre-year during poverty. It occurs during 10 to 17 years. On the other hand, girls usually stop their height before age 15. To tackle heights and know at what age how much height will be. Look at the tables below:

Age (years) Median female height Median male height
4 3 ft 3 in 101 cm 3 ft 4 in 102 cm
6 3 ft 9 in 115 cm 3 ft 9 in 115.5 cm
8 4 ft 2 in 127.5 cm 4 ft 2 in 128 cm
10 4 ft 7 in 138 cm 4 ft 6 in 138.5 cm
12 4 ft 11 in 151.5 cm 4 ft 11 in 149 cm
14 5 ft 4 in 160.5 cm 5 ft 4 in 164 cm
16 5 ft 4 in 162.5 cm 5 ft 8 in 173.5 cm
18 5 ft 4 in 163 cm 5 ft 9 in 176 cm
20 5 ft 5 in 163 cm 5 ft 9 in 177 cm
