Normal Blood Pressure Ranges for Children (Ages 0–17): AAP Guidelines

Children's blood pressure norms aren't one-size-fits-all—they vary by age, sex, and height percentile. The table below provides general systolic/diastolic ranges (mm Hg) based on American Academy of Pediatrics (AAP) guidelines. For precise percentiles, clinicians use standardized BP tables or calculators incorporating all three variables.

Age Group	Systolic (mm Hg)	Diastolic (mm Hg)
Birth to 1 month	60–80	35–50
1 month to 1 year	75–100	50–70
1 to 2 years	80–110	55–80
3 to 5 years	85–120	60–85
6 to 9 years	90–135	65–95
10 to 12 years	95–145	70–100
13 to 15 years	100–155	75–105
16 to 17 years	105–165	80–110

Important Context

• These are general reference ranges, not diagnostic cutoffs.
• BP should be measured correctly: right arm, supported at heart level, appropriate cuff size (bladder width ≥40% arm circumference, length 80–100%), after 5 minutes rest.
• Elevated readings on ≥3 separate occasions → further evaluation.
• Genetics, growth spurts, obesity, sleep apnea, kidney disease, medications, and anxiety ("white coat") all influence readings.

When to Consult a Pediatrician

• Consistently elevated readings
• Family history of early hypertension
• Obesity, known kidney/heart conditions
• Symptoms: headache, visual changes, chest pain, seizures

Accurate measurement and longitudinal tracking matter more than a single number. Your pediatrician interprets BP in the context of your child's complete health picture.
