A growth chart can determine whether your baby is developing the way he’s supposed to. Boys and girls have different growth rates as boys tend to be slightly heavier and taller than girls on average. A baby boy percentile growth chart can help you track your baby boy’s growth accurately.

Baby Boy Growth Chart

Here’s the baby boy growth chart as given by the World Health Organisation. The chart gives the height, weight and head circumference readings from the 3rd to the 97th percentile. To track your baby’s growth, plot his measurements over a graph and compare them with this chart.

Age in Months Height (cm) – 3rd to 97th percentile Weight (Kg) – 3rd to 97th percentile Head circumference (cm) – 3rd to 97th percentile
0 46.3 – 53.4 2.5 – 4.3 32.1 – 36.9
1 51.1 – 58.4 3.4 – 5.7 35.1 – 39.5
2 54.7 – 62.2 4.4 – 7.0 36.9 – 41.3
3 57.6 – 65.3 5.1 – 7.9 38.3 – 42.7
4 60.0 – 67.8 5.6 – 8.6 39.4 – 43.9
5 61.9 – 69.9 6.1 – 9.2 40.3 – 44.8

12 71.3 – 80.2 7.8 – 11.8 43.6 – 48.5

Tips To Read the Growth Chart

Understanding the height and weight chart is simple. If you’re referring to a baby boy weight chart by month, you would see that the vertical axis on the left of the chart gives the months of the baby. The horizontal axis has the baby’s weight marked on it. For example, if your baby is in the 25th percentile, it means that 24% of baby boys of the same age weigh less than your child and 75% weigh more. A baby boy height and head circumference chart are similar to the weight chart.




Keep in mind that the percentile for height and weight need not always be the same. For example, your baby may be 40th percentile in weight but in the 60th percentile in height and this can vary as they grow older.

How to Measure Your Baby Boy at Home

You can easily measure your baby at home. Here’s how:





  • Height: Measuring your baby’s height may be a bit difficult as he might wriggle a lot. Place him on a flat surface like a bed or table and stretch his legs out. Using a tape measure, note his height from the top of his head to the soles of his feet.
  • Weight: You can get a baby weighing scale to measure your boy’s weight.
  • Head Circumference: Wrap a tape measure around the widest part of your baby’s head. It should pass above the eyebrows and ears.

Why Is It Important to Have a Baby Boy Growth Chart?

A growth chart helps both you and your paediatrician assess your child’s nutrition status, height and weight. Proper development is crucial in the first six years of a baby’s life, so it’s important to track your boy’s growth with the help of this chart.

What Factors Influence Your Baby’s Growth?

Your baby boy’s growth depends on multiple factors such as:




1. Feeding

All the nutrition that your baby needs comes from feeding and it significantly determines his growth. Until six months, he’s dependent on breast milk or formula for his nourishment. Adequate feeding also supports other factors that influence growth.

2. Mother’s Health During Pregnancy

Your diet, weight, and lifestyle have a major influence on how your baby develops in the womb. That, in turn, affects the nutrients stored in your baby’s body and influences his growth in the first year.





3. Baby’s Birth Weight

The birth weight is an indicator of how well your baby was nourished during pregnancy.

4. Genes

Genes play a major role in a baby’s development. Babies whose parents are tall and well-built tend to be in a higher percentile of height and weight. On the other hand, babies of moderately-built parents tend to be lean.




5. Minor Ailments

Flu and ear infections can temporarily affect your baby’s growth. He may not feed well when he’s sick. But he should return to normal once he starts recovering.

6. Mother’s Health After Pregnancy

If you’ve been unwell or suffer from conditions such as postnatal depression, it affects the way you take care of your baby. This has an influence on his growth rate. However, it will improve once you recover from the ailment.





Does Birth Weight Affect a Baby’s Growth?

Not really. Birth weight plays an insignificant role in a baby’s growth and development. Rather, genes from the parents determine this. After birth, the growth rate becomes more dependent on the infant’s genetic background. An important phenomenon often called catch-up or catch-down growth occurs in the first 18 months of life. In two-thirds of children, the growth rate percentile shifts linearly until the child reaches his or her genetically determined growth channel or height percentile. Some petite babies grow into tall and muscular men while some chubby babies become lean as they grow up.

When Should You Consult a Doctor?

Some children who grow significantly later in life. It’s the opposite for kids who grow rapidly at a young age. To know if your baby is growing well, plot his height and weight regularly and compare with a growth chart. However, if you see that your boy is at either end of the infant boy growth chart for a long time, it’s best to consult a paediatrician.
