Growth velocity

cm/year from two height measurements – classified against WHO, CDC, Kromeyer-Hauschild or KiGGS

Child

Sex

male female

Date of birth

For classification on the reference; without a date of birth, only the growth rate is calculated.

Gestational age at birth (weeks, in preterm infants)

If entered, the corrected age is used up to a chronological age of 24 months (age minus the weeks remaining to the due date at 40 weeks of gestation); after that, the chronological age.

Measurements

Date of measurement 1

Height at measurement 1 (cm)

Date of measurement 2

Height at measurement 2 (cm)

Frequently asked questions

Growth velocity: What does this calculator compute?

Calculates growth velocity in cm/year from two height measurements and compares it with the median increment of the selected reference in the same age interval and with the increment that would maintain the percentile of the first measurement; z-score and percentile of both measurements are also given.
