Use age and gender specific chart (updated WHO 2009 charts of healthy babies breastfed to 6 months)
Abnormal if <0.4th or >99.6th (>SD from normal), outside parental height, discrepant from weight, crossing of centile lines
Calculate midparental height to put into context

-

Pathology
Severe IUGR and prematurity plus
poor postnatal growth can restrict height
LBW associated with childhood obesity
