Here’s a general guide to normal blood pressure values according to age, based on guidelines from organizations like the American Heart Association (AHA) and pediatric references for children. Blood pressure is measured in millimeters of mercury (mmHg) and expressed as systolic/diastolic (SBP/DBP).
Adults (18 years and older)
| Category | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Normal | <120 | <80 |
| Elevated | 120–129 | <80 |
| Hypertension Stage 1 | 130–139 | 80–89 |
| Hypertension Stage 2 | ≥140 | ≥90 |
| Hypertensive Crisis | >180 | >120 (emergency) |
Children and Adolescents (1–17 years)
Blood pressure in children varies by age, sex, and height percentile, so values are given as percentiles:
-
Normal: <90th percentile for age, sex, and height
-
Elevated: 90th–95th percentile or 120/80 to <95th percentile (whichever is lower)
-
Hypertension: ≥95th percentile on 3 separate readings
Approximate average values by age:
| Age | Systolic (SBP) | Diastolic (DBP) |
|---|---|---|
| 1–2 yrs | 90–105 | 55–70 |
| 3–5 yrs | 95–110 | 60–75 |
| 6–9 yrs | 95–115 | 60–75 |
| 10–12 yrs | 100–120 | 60–80 |
| 13–15 yrs | 105–125 | 65–85 |
| 16–17 yrs | 110–130 | 65–85 |
Notes
-
Blood pressure naturally increases with age.
-
Individual factors such as body size, activity, and health conditions can influence normal ranges.
-
Always measure using a properly sized cuff and in a calm setting.
If you want, I can make a clear chart combining all age ranges from children to adults for quick reference—it’s really handy for checking blood pressure at a glance.
Do you want me to create that?
