Whats A Normal Blood Pressure

A lot of patients ask me when Im going around doing vitals what a normal blood pressure is. I looked around and found a chart and thought I would post this.

The Blood Pressure Chart


CategorySystolic Blood Pressure (mmHg)Diastolic Blood Pressure (mmHg)
NormalLess than 120Less than 80
Prehypertension120 to 13980 to 89
Stage 1 Hypertension (mild)140 to 15990 to 99
Stage 2 Hypertension (moderate to severe hypertension)160 and higher100 and higher

Low Blood Pressure

Low blood pressure is not determined by blood pressure levels, but by symptoms. A drop in normal blood pressure that causes no symptoms in one person may cause dangerous symptoms in another. Symptoms of low blood pressure include:
  • Chest pain
  • Dizziness
  • Fainting
  • Heart attack
  • Kidney failure
  • Lightheadedness
  • Shock.

Normal Blood Pressure for Children

Because children naturally have a normal blood pressure that's lower than an adult's, a child is at risk for hypertension at much lower blood pressures. Normal blood pressure for children also varies by gender:
