Height Weight Chart by Age

The name depends on the age group. For adults, it works as a weight by height chart: height runs across the horizontal axis and weight ranges are drawn vertically. For infants, the correct term is weight-for-length. Boys and girls use age-specific BMI-for-age references.

Not for the standard adult BMI cutoffs used here. Underweight is below 18.5, the healthy range is 18.5-24.9, overweight is 25-29.9, and obesity starts at 30. Those adult cutoffs are the same for men and women.

For ages 2-19, a boys height weight chart and a girls height weight chart use BMI-for-age references instead of adult BMI ranges. Age and sex both matter, so the same height and weight can fall in a different band for a younger child or an older teen.

The infant view uses WHO weight-for-length references. For children, you can choose CDC or WHO where the data is supported. NHS is linked as an outside reference, but this is not an NHS chart.

A height to weight chart shows weight ranges across many heights. A BMI chart labels BMI categories, while a BMI calculator returns one exact value. This page uses BMI cutoffs to draw the adult boundary lines; use the dedicated BMI Calculator when you need one number.

Babies under 2 are usually measured lying down, so the measurement is length, not standing height. That is why the infant view uses WHO weight-for-length references from birth through 24 months.

No. It is a range chart, not an ideal-weight diagnosis. It can show where a measurement sits against adult BMI ranges, infant weight-for-length percentiles, or child BMI-for-age references.

Use the graph for a quick visual read. Use the adult table when you need exact threshold weights for one height, such as where BMI 18.5, 25, or 30 begins.

Yes. Switch to US units to enter feet, inches, and pounds. The chart converts the values behind the scenes so the plotted point stays in the same range.

Do not use one chart point as the only source for medical decisions, rapid weight change, pregnancy, illness, eating-disorder risk, or a child being monitored for growth. For children, the trend over time matters more than one marker.
