Growth & Development
Updated on 30 January 2024
From the time their child is first handed in their arms to the moment, their little one is ready to let go of their hand, parents keep worrying about their child’s height and weight. It is common for parents to wonder whether their child has the right height and right weight and if their little one is growing fine. In this article, we put your minds to ease with a height and weight chart for boys and girls different ages- newborns, toddlers and preschoolers. We will also discuss the factors affecting the growth of children.
Babies are measured in length instead of height for the initial months as they cannot stand tall yet. The length of your baby as measured lying down is the same as their height when standing up. You may notice that your pediatrician always tracks the weight and length of your baby along with the head circumference to ensure any irregularities or anomalies can be identified and addressed instantly.
The average weight at birth of an Indian baby is between 2.7 to 3.2 kgs. In the following baby height & weight chart, we take a look at the height and weight chart for girls and boys in the first year of life as per WHO.

We hope you found these height and weight chart for girls and boys through different age groups helpful. Now, let's understand the factors that can affect the height and weight of children.
The genes your child inherits from you play the most important role in their height and weight. But besides genes, there are some other factors too:
If your baby arrived long after their due date or a little too early, they may be larger or smaller respectively. Additionally, your health and habits during pregnancy such as poor diet, smoking or consumption of drugs and alcohol may also lead to low birth weight. However, if you gained plenty of weight during pregnancy, your baby may be healthier than average.
Hormones play an important role in determining your child’s height and weight. If your kid suffers from a hormonal imbalance like low growth hormone levels or low thyroid levels, it may decline their growth.
Side effects from certain medications or their prolonged use such as that of corticosteroids may also retard the growth of your child.
If your child suffers from a chronic illness like cancer, kidney disease or any eating disorder that affects their ability to eat or absorb nutrients, their growth may get slowed down. Genetic health conditions such as Down Syndrome, Noonan Syndrome or Turner Syndrome can also affect their weight and height.
Several studies over the years have shown relations between sleep and growth. Children who sleep better and uninterrupted may grow better than children with disturbed or restless sleep. Ensure that your baby gets a longer and peaceful sleep.
The average weight at birth of an Indian baby is between 2.7 to 3.2 kgs. As babies grow, this average changes as per the baby weight chart above.
Factors such as pregnancy term and health, health conditions, sleep and hormones can affect baby weight.
It’s normal for a baby’s height and weight to not fall within the percentile range. Each baby is different and grows at their unique pace.
Babies experience growth spurts according to which they may lose or gain weight. A normal baby should gain somewhere between 400 grams to 1 kg weight each month in the first year.
If your baby is underweight, you may add healthy foods to their diet to accelerate weight gain.
Some possible reasons for your baby not gaining weight could be hormonal imbalance, prolonged use of certain medications or chronic illnesses.
Yes, the same baby’s weight chart is applicable to premature babies. However, for babies born before their term, month 0 is considered the date of a full-term pregnancy.
Each child is unique and it’s normal for them to grow at different rates. Don’t worry if your baby’s height and weight are lower or higher than the average. The numbers in the above height and weight chart for boys and girls are just benchmarks that your child may fall short of or exceed. If you’re still concerned about your child’s weight and height, you can always consult a pediatrician.
