Weight-for-Stature Percentile Calculator (Chinese National Standard)

How Weight-for-Stature Percentiles Work (Chinese National Standard)

Weight-for-stature percentiles evaluate whether a child’s weight is proportionate to their standing height. This is useful for assessing nutritional status in older children who are measured standing up.

This calculator uses data from the Chinese National Survey, covering statures from 65 cm to 125 cm at 5 cm intervals with LMS interpolation between points.

Example Calculation

A boy with a standing height of 100 cm and a weight of 15.5 kg. Using the Chinese National Standard LMS values for boys at 100 cm and applying the LMS formula, this weight falls near the 50th percentile — indicating a healthy weight-to-height ratio.

Frequently Asked Questions

What stature range does this calculator cover?

This calculator covers standing heights from 65 cm to 125 cm using Chinese national growth standards.

How is this different from weight-for-length?

Weight-for-length uses recumbent length (measured lying down) for younger children. Weight-for-stature uses standing height for older children. Standing height is typically slightly shorter than recumbent length.

What does a high weight-for-stature percentile indicate?

A high weight-for-stature percentile (above the 85th) may suggest the child is overweight relative to their height. However, a single measurement is not diagnostic. Trends over time and clinical context are more important. Consult a pediatrician for proper evaluation.
