Stature-for-Age Percentile Calculator (WHO, 2-5 Years)

How Stature-for-Age Percentiles Work (2-5 Years)

Stature (standing height) is the standard measurement for children aged 2 years and older. This calculator uses the WHO Child Growth Standards to compare your child’s height to healthy children of the same age and sex, covering ages 24 to 60 months (2-5 years).

Unlike recumbent length (measured lying down for infants), stature is measured with the child standing upright. Standing height is typically about 0.7 cm less than recumbent length, which is why the WHO provides separate charts for each.

When to Use This Calculator

• Children aged 2-5 years who can stand independently
• Standing height measurements taken with a stadiometer or wall-mounted ruler
• For children under 2, use our length-for-age calculator instead

Example Calculation

A 3-year-old boy (36 months) measuring 96.1 cm tall would be approximately at the 50th percentile, since the WHO median stature for boys at 36 months is 96.0835 cm.

Frequently Asked Questions

What age range does this calculator cover?

This calculator covers children aged 24 to 60 months (2 to 5 years). For children under 2, use the WHO length-for-age chart which measures recumbent length.

What is the difference between stature and length?

Stature is standing height (measured upright), while length is recumbent (lying down). Standing height is about 0.7 cm shorter than recumbent length. The WHO uses length for children under 2 and stature for ages 2-5.

Should I be concerned about a short or tall child?

Height is largely genetic. A child who is consistently at the 10th percentile but whose parents are also short is likely growing normally. Pediatricians look for changes in growth velocity and crossing of percentile lines over time.

Can I enter height in inches?

Yes, you can enter the measurement in either centimeters or inches. The calculator converts inches to centimeters automatically.
