Child Height and Weight Chart USA

The child height and weight chart usa consist of a series of percentile curves that illustrate the distribution of selected body measurements in children. Pediatric growth charts are based on measurements taken from large groups of infants or school age children and these measurements reflect the range of normal variation among individuals in each age group.

Child height and weight chart usa consist of a series of percentile curves that illustrate the distribution of selected body measurements in children. The curves are generated by plotting the CRF percentage point distribution on a graph and connecting these points with straight lines. The curve patterns are different for boys and girls, because boys and girls grow differently after infancy. In addition to the charts themselves, there is also information about how to interpret them and what they mean if your child is at a different level than one would expect in comparison to his or her peers.

Babies come in all shapes and sizes, and all babies grow at their own pace. Child height and weight chart USA regular checkups, the healthcare provider will plot certain measurements on a baby growth chart to make sure your little one is on the right track. The chart might look daunting but your provider can help you understand this useful tool and what the results mean for your child.

Reading a child’s height and weight chart USA may look overwhelming, but it’s actually pretty easy to understand. These charts measure your child’s height and weight as well as plot their head circumference—all critical factors in making sure your little one is growing up healthy. Your healthcare provider will use these charts at every well-child checkup to make sure your baby is on track for growth, development, and overall wellness.

From the day he or she is born, your baby will undergo regular health checkups to make sure everything is going smoothly. The growth chart is a vital component of any pediatric appointment. At the end of each visit, your child’s doctor or nurse will plot your little one’s height, weight, and head circumference on the chart.

It can be hard to keep up with all the growth milestones your baby should hit in the first year, and it can be even harder to know whether they’re normal. The good news is that healthcare professionals have created a baby growth chart that can put your mind at ease. Learn how to read your baby’s growth chart and what it means for them.

Healthcare providers have access to a wealth of information about your growth and development, and they use it to track your baby’s health on a regular basis. A baby growth chart is used to record physical measurements that indicate whether you’re growing at the proper pace. Charting is meant to help pediatricians identify health problems in kids under 2 years old.

A baby growth chart can show you the measurements your child has achieved or the ones they are expected to achieve at certain ages. These measurements are plotted on a grid chart to demonstrate your child’s measured height, weight, and head circumference over time.

The World Health Organization (WHO) released a new international growth standard statistical distribution in 2006, which describes the growth of children ages 0 to 59 months living in environments believed to support what WHO researchers view as optimal growth of children in six countries throughout the world, including the U.S. The distribution shows how infants and young children grow under these conditions, rather than how they grow in environments that may not support optimal growth.

What Are Baby Growth Charts?

Baby growth charts are important tools healthcare providers use to check your little one’s overall health. The charts assess how your baby is growing compared with other children of the same age and gender, and to see how your child is developing over time. Growth standards used for babies under 24 months old are based on the following:

  • Head circumference. This is the distance around the largest part of the head and indicates how your baby’s brain is growing.
  • Weight-for-length. This measures your baby’s weight along with their length (height).
  • Weight-for-age. This measurement tracks your baby’s weight at a particular age.
  • Length-for-age. This measures your baby’s length (height) at a particular age.

Your child’s healthcare provider will use different growth charts for baby boys and girls, and different charts for babies younger than 24 months and for those 2 years and older.

In SummaryYour baby’s healthcare provider will use growth charts (specific to boys and girls and certain age ranges) to track your child’s development over time. These will include head circumference, weight along with length (height), weight for age, and length (height) for age. 

It’s helpful to know that these charts offer information that your provider can assess in the context of other baby developmental milestones and genetic factors. You can find and download the charts below.

When and How Is Your Baby Measured?

You probably chose your child’s healthcare provider while pregnant, and your baby’s initial office visit will be within a few days of their birth or shortly after you leave the hospital. Starting with this first appointment, checking your baby’s growth will become a routine part of each visit, whether your little one is 1 month or 1 year. Initially, your baby’s checkups will take place every few weeks, and then every few months until your baby turns 1. Your provider will let you know if you need to visit more often and when to schedule future appointments. Don’t hesitate to ask any questions you might have about your baby’s health and development—your child’s healthcare provider is your partner and can reassure you that you’re doing a great job and help you resolve any issues that pop up! Here’s how babies are usually weighed and measured:

  • Head circumference: The healthcare provider will wrap a soft tape measure around the widest part of your baby’s head, from above the eyebrows, passing above the ears, to the back of the head.
  • Length: Measuring the length (a.k.a. height) of a wriggly baby may be tricky, but your provider is an expert at this! As your little one lies on a flat table, the provider will gently stretch out your baby’s legs to get an accurate measurement from the top of their head to the soles of their feet.
  • Weight: With your baby undressed, your child’s provider will likely use a baby scale to get the most accurate reading.
In SummaryYour baby’s healthcare provider will weigh and measure your little one at each regular health checkup. The provider will measure around your baby’s head above the ears to determine head circumference; measure from the top of your baby’s head to the bottom of their feet to determine length (height); and weigh your baby, undressed, on a baby scale.

How to Read a Baby Growth Chart

Once you have your measurements, you might look at a baby growth chart and wonder how you are supposed to make sense of it. Your baby’s healthcare provider can help you understand your child’s results and plot them on the chart at the health checkup, but in the meantime here’s a quick guide on how to read these charts. Remember, it’s important to use the baby boy growth charts if you have a boy and the baby girl growth charts if you have a girl.

Head Circumference Percentile

Although these charts look like something only Einstein could figure out, they’re actually fairly simple to read once you get the hang of it. To find your baby’s head circumference percentile in the growth chart linked above, following these steps:

  1. Find your baby’s age in months at the top of the chart. Only some months are numbered, but each month is represented by a vertical line.
  2. Find your baby’s head circumference measurement on the left side (measurements are provided in both inches and centimeters).
  3. Follow these horizontal and vertical lines until they intersect. In most cases, they will intersect on a curved line.
  4. Follow the curved line to the right until it ends, and here you’ll see a number on a white background. This number indicates your baby’s head circumference percentile on the growth chart.
Baby growth chart for girls

TipIn the example above, the child is a 3-month-old girl with a head circumference of 15.5 inches. As the growth chart indicates, this baby is in the 50th percentile, meaning half of all 3-month-old baby girls have bigger heads, and the other half have smaller heads.

Weight-for-Length Percentile

Now that you’ve found your baby’s head circumference percentile on the growth chart, it will be easier to do the same for their weight. Follow the steps below:

  1. Find your child’s length in inches or centimeters at the bottom of the grid.
  2. Find your child’s weight (in pounds or kilograms) on the left side of the grid.
  3. Follow the horizontal and vertical lines of these two measurements until they intersect on the growth curve.
  4. Follow the curved line until the end to find your baby’s weight-for-length percentile on the growth chart.
Baby growth chart for boys

TipIn the example above, the child is a boy who weighs 10 pounds and is 21 inches long. According to the growth chart, this baby is in the 90th percentile, meaning 90 percent of baby boys this length (height) have a lower weight, and 10 percent have a higher weight.

Length-for-Age Percentile

To determine your baby’s length-for-age (height) percentile on the growth chart, follow the steps below:

  1. Find your baby’s length (in inches or centimeters) on the left side of the grid.
  2. Find your child’s age in months at the bottom of the chart.
  3. Track these horizontal and vertical lines until they intersect on the growth curve.
  4. Follow that curve until the end, where the percentiles are written on a white, shaded background.
Baby growth chart for girls length for age

TipIn the example above, the child is an 18-month-old girl who is 30.5 inches long. As the growth chart indicates, this toddler is in the 10th length (height) percentile, meaning 10 percent of children her age are shorter, and 90 percent are longer (taller).

Weight-for-Age Percentile

Lastly, use the baby growth chart to track your little one’s percentile for weight using the following steps:

  1. Find your baby’s weight (pounds or kilograms) on the right side of the grid.
  2. Find your child’s age in months at the top of the chart.
  3. Follow these horizontal and vertical lines until they intersect on the curved line.
  4. Follow that curved line until the end, where the percentiles are written on a white, shaded background.
Baby growth chart for boys length for age

TipIn the example above, the child is a boy who is 12 months old and weighs 23 pounds. According to the growth chart, this baby is in the 75th weight percentile, meaning 75 percent of 1-year-old baby boys weigh less, and 25 percent weigh more.

How to Interpret Baby Growth Chart Percentiles

Your child’s healthcare provider is the best person to explain these results to you. Remember, the charts show the typical growth patterns for baby boys and girls, and there is a wide range of healthy results. There’s no ideal result when viewed individually, but, ideally, your child would follow along the same growth pattern (the curved line) over time. As a result, their height and weight would grow in proportion to one another.

What Are the Percentiles?

The baby growth chart shows which percentile your child is in compared with others of the same age and gender. Percentiles are shown as curved lines. Here’s another example and explanation:

  • If your child is in the 70th percentile (out of 100) for length-for-age, this means two things:
  • Seventy percent of babies the same age and gender are shorter than your baby.
  • The remaining percentage (30 percent) of babies the same age and gender are longer than your baby.

But, this one point doesn’t show the complete picture. Your child’s provider will assess several values over time to determine the trend of how your baby is growing compared to the average growth curve on the chart. Try not to become too focused on a single number. There is a wide range of healthy sizes and lengths, and many factors influence your child’s growth, including genetics, environmental factors, nutrition, activity levels, and health conditions. Another thing to consider is when babies have growth spurts, which can vary from child to child. For example, breastfed and formula-fed babies grow in slightly different patterns. Breastfed babies typically put on weight more slowly than formula-fed babies, and formula-fed infants typically go through a growth spurt and gain weight more quickly after 3 months of age.

With all these different factors at play, it’s important to assess these percentiles over time and with your child’s provider.

What Happens if My Baby’s Growth Pattern Changes?

A different growth pattern doesn’t always indicate a problem. Your child may simply be experiencing a growth spurt, which is partly why it’s so important to look at these percentiles over time. However, your child’s healthcare provider will also investigate a growth pattern change to rule out any issues. Typically, a healthy, well-nourished baby grows at a fairly predictable rate. Any change in this rate can help your baby’s provider detect and address any feeding, developmental, or medical issues.

What Happens if My Baby Is Above or Below the Average?

Most children fall between the 3rd and 97th percentiles on baby growth charts for head circumference, weight, and length (height). But if your child does not, know that there are many factors at play, and that your child’s provider will consider other developmental milestones and family genetics. Baby growth chart percentiles aren’t like an algebra exam. Just because your little one is in the 50th percentile doesn’t mean there’s a problem! In fact, that figure means your baby is right in the middle of the average. What’s more important is how your child grows over time. Plus, some families might have fast-growing babies, while others have slow and steady gainers. Regardless of what you see on your baby’s growth chart, try not to worry, and keep these individual differences in mind as you follow your child’s development. If the healthcare provider determines that your baby is overweight, underweight, growing too fast, or growing too slowly, trust that your little one is in good care, and follow the provider’s recommendations.

FREQUENTLY ASKED QUESTIONS

The Bottom Line

Baby growth charts, whether for boys or girls, can be confusing at first glance. In the end, it’s always best to look at your baby’s growth chart percentiles together with their healthcare provider over time, and to avoid comparing your child to others. Instead, focus on all of the growing your little one is doing! And, if your baby’s healthcare provider says they’re on the right track, you can take pride in your little one’s progress regardless of the value on the chart. In fact, you’ll probably be delighted (and maybe even a little surprised) when you see how big your baby is now compared to the day they were born. Your little one is a moving, grooving, and growing machine, and there’s so much to look forward to, such as watching them start to crawl and walk, hearing those first laughs, and helping them develop those fine motor skills.

Recommendation

CDC recommends that health care providers:

  • Use the WHO growth charts to monitor growth for infants and children ages 0 to 2 years of age in the U.S.
  • Use the CDC growth charts to monitor growth for children age 2 years and older in the U.S.

Why use WHO growth standards for infants and children ages 0 to 2 years of age in the U.S?

  • The WHO standards establish growth of the breastfed infant as the norm for growth.Breastfeeding is the recommended standard for infant feeding. The WHO charts reflect growth patterns among children who were predominantly breastfed for at least 4 months and still breastfeeding at 12 months.
  • The WHO standards provide a better description of physiological growth in infancy.Clinicians often use the CDC growth charts as standards on how young children should grow. However the CDC growth charts are references; they identify how typical children in the US did grow during a specific time period. Typical growth patterns may not be ideal growth patterns. The WHO growth charts are standards; they identify how children should grow when provided optimal conditions.
  • The WHO standards are based on a high-quality study designed explicitly for creating growth charts.The WHO standards were constructed using longitudinal length and weight data measured at frequent intervals. For the CDC growth charts, weight data were not available between birth and 3 months of age and the sample sizes were small for sex and age groups during the first 6 months of age.

Why use CDC growth charts for children 2 years and older in the U.S.?

  • The CDC growth charts can be used continuously from ages 2-19. In contrast the WHO growth charts only provide information on children up to 5 years of age.
  • For children 2-5 years, the methods used to create the CDC growth charts and the WHO growth charts are similar.
