Blood Pressure Calculator
See your blood pressure category from systolic and diastolic readings.

Blood pressure calculator
Enter systolic, diastolic, and pulse readings.
Pressure during heartbeats.
Pressure between beats.
Heartbeats per minute.
Pulse
72 bpm
Blood pressure category
Stage 1 hypertension range
Your reading may fall within a stage 1 high blood pressure range based on common guideline categories.
Pulse interpretation
72 bpm — Normal resting pulse
This pulse commonly falls within the typical adult resting range of 60–100 beats per minute.
Systolic value
120 mmHg
Category range: 130–139
Diastolic value
80 mmHg
Category range: 80–89
This tool is for education only. It does not diagnose, replace medical care, or account for your full health history. Very high readings, very low readings with symptoms, or persistent abnormal readings should be discussed with a healthcare professional.
Personalized interpretation
Your reading may fall within the Stage 1 hypertension range.
Single readings do not diagnose a condition. Persistent abnormal readings should be reviewed with a healthcare professional.
Blood pressure and pulse can change due to posture, activity, stress, sleep, caffeine, hydration, medication, illness, and measurement technique.
Emergency symptoms such as chest pain, severe shortness of breath, confusion, fainting, or stroke symptoms require immediate medical attention.
Blood pressure category guide
Categories are based on common educational ranges. Repeated readings and clinical context matter more than a single reading.
Low Blood Pressure
< 90 / < 60
May be low, especially if symptoms are present.
Normal
< 120 / < 80
Commonly categorized as within the normal range.
Elevated
120–129 / < 80
Systolic pressure is above normal while diastolic remains below 80.
Stage 1 Hypertension
130–139 / 80–89
May fall within a stage 1 high blood pressure range.
Stage 2 Hypertension
≥ 140 / ≥ 90
Commonly categorized as a higher blood pressure range.
Hypertensive Crisis
> 180 / > 120
Very high reading where urgent medical guidance may be needed.
What the numbers mean
How to measure accurately
Use a properly fitted cuff, sit with your back supported, keep your feet flat, and rest quietly before measuring.
Avoid caffeine, nicotine, exercise, or stress immediately before a reading when possible.
Multiple readings over time are usually more useful than one isolated reading.
Factors that affect blood pressure and pulse
Blood pressure and pulse can fluctuate throughout the day.
Healthy lifestyle considerations
Limitations and medical disclaimer
Calculator results are informational only. Home readings can vary, and diagnosis requires medical evaluation by a qualified healthcare professional.
Seek urgent help for very high readings, severe symptoms, or low readings with fainting, confusion, chest pain, or severe weakness.
Formula / reading explanation
Blood pressure reading = systolic / diastolic mmHg + pulse bpmExample: 120/80 mmHg with a pulse of 72 bpm means 120 systolic, 80 diastolic, and 72 heartbeats per minute.
