Do you wonder sometimes about our bodies? How amazing our bodies are. We all have so many questions about the human body as to what is inside it, how it works, and what is the proportion of different body parts.

Growth is very important for humans as well as for animals. The changes in the body proportion happen systematically so that the ratio between the head and body height decreases with time. The study of body proportions is substantial as it takes a look at the relations of the human body as a whole and with each other too. We will discuss the normal head circumference of newborns, newborn baby height and much more. Let us take a look at the article below to help under this topic better.

When babies are born, their heads are comparatively bigger than their bodies. Also, the weight of the human head is higher. It is said that their big heads hold big brains as they are in the process of learning many things. But as time passes by and they grow old and tall their body proportion changes. Other body parts start growing like their limbs and trunk but the head does not grow much after a while.

## Basics of Human Proportions

The key principle of any human body is the proportion between its body parts. Even though there is a contrast difference between individuals, the proportions have to be within the standard range. There could be a slight difference as every individual is different. In medical science, the human body runs from the top to the bottom and runs through the middle of the body.

In a human figure, the basic unit of measurement is the “head”- the distance between the top of the head to the chin. Therefore the head would fit 8 times the total height.

## The Ratio of Head-Body Proportions

The ratio between the head and the body is a bit complex. The height and the normal head circumference of newborns are measured in centimetres. The current study shows that there has to be a significant relationship between the head and the body.

The head-body ratio changes from one to four for a small child to one to eight for an adult.

Not every adult has a 1 to 8 head-to-body ratio. If we take an average, generally this ratio comes between 1 to 6.5 and 1 to 8. Comparatively, infants and children have bigger heads but their body becomes taller than their head as they grow.

## Types of Body Proportions

The human body is divided into three types of body proportions.

1. 5-5

2. 4-6

3. 3-7

There is a formula with the help of which you can calculate your body type.

Body ratio formula = (Height - Leg length): Leg length

E.g: If your,

Height = 174 cm

Leg length (waistline to foot) = 95 cm

Body ratio = (Height - Leg Length): Leg Length

=  (174-95 cm) : 95 cm

=  79: 95 cm

= 1:1.2

There are quite a few physical changes that happen in the human body in the first number of years. Let us have a look at some of these interesting facts:

• Did you know that while we are in the womb, our head takes about 50% of our total length?

• Men are 8 heads high. Pretty sure you must be wondering what this means? It means that the height of an average person is equal to eight times the height of a regular head.

• The average newborn baby height is 19–20 inches or 48.2–50.8 centimetres.

• The female body on average is smaller than that of a man. A woman’s height can be 7 or 7.5 heads the height of a regular head.

• There always are exceptions where women can be much taller than men.

## Summary

From this topic on Head Body Proportions, we have learnt that the human body is one of the most complex shapes on the planet. It is very important to learn about the proportions as it is necessary to be anatomically correct. The proportion changes from birth to till the start of your adulthood. It is a fact that kids belonging to the same family also don't grow at the same speed. And the average model helps us to determine which category we belong to. We hope you enjoyed reading this article, in case of any other doubts, feel free to ask in the comments.

## FAQs on Head Body Proportions

1. What is a good head-to-body ratio?

An average head-to-body ratio is around 7 and a half heads tall, which includes the head. If you take an ideal figure, it can go up to 8 heads tall.

2. How big is a baby’s head as compared to its body?

A newborn baby’s head measures around 13 ¾ inches or 35 cm. The head of a newborn baby is half the baby’s length in cm and then we need to add 10cm.

3. Who proposed the concept of head-body count?

It was the Greeks who created the classical standard of measuring the height of a person through the head-body count. They defined proportion by using the height of the head as a means to judge a human's height.
