AHA blood pressure categories.
The American Heart Association defines five blood pressure categories plus hypotension. Each carries different clinical guidance and risk implications.
Under 120 / Under 80 mmHg
Risk: Low
Maintain with healthy diet, regular exercise, and low sodium intake. Get checked once every two years if you have no other risk factors.
120 to 129 / Under 80 mmHg
Risk: Moderate
Lifestyle changes recommended. Reduce sodium, increase activity, manage weight. Doctor may monitor more frequently. Not yet treated with medication in most cases.
130 to 139 / 80 to 89 mmHg
Risk: Moderate to High
Talk to your doctor. Lifestyle changes are the first step. Medication may be added depending on cardiovascular risk factors and overall health profile.
140 or higher / 90 or higher mmHg
Risk: High
Medication is typically prescribed alongside lifestyle changes. Regular monitoring and follow-up appointments are essential. Do not manage this alone.
Over 180 / Over 120 mmHg
Risk: Emergency
Seek emergency medical care immediately. Wait five minutes and retest. If still elevated, call 911 or get to an ER. Do not drive yourself.
Under 90 / Under 60 mmHg
Risk: Situational
May be normal for some people. Symptomatic hypotension (dizziness, fainting, blurred vision) warrants evaluation. Can be caused by dehydration, medication, or underlying conditions.

Additional reference tables.
The BPTrack app includes 25+ tables beyond the five AHA categories. A preview of what is inside.
Blood pressure norms shift with age. What is normal at 25 differs from what is expected at 65. These tables give AHA-referenced ranges by decade.
The difference between systolic and diastolic. Widening pulse pressure can indicate arterial stiffness. Tables include normal ranges and what elevated readings suggest.
How readings change when standing from sitting or lying. A drop of 20+ mmHg systolic on standing may indicate orthostatic hypotension, common in older adults and those on certain medications.
Readings taken in a clinical setting are often higher than at home due to anxiety. The AHA recommends home monitoring to compare. These tables explain the discrepancy and what to do about it.
When only the top number is elevated (140+ systolic with normal diastolic). More common in older adults and carries its own risk profile. Tables include thresholds and treatment guidance.
24-hour BP monitoring gives a fuller picture than a single office reading. These tables include daytime, nighttime, and 24-hour average thresholds used in clinical interpretation.
How to get an accurate reading.
The reading is only as useful as the technique. Most home measurements are taken incorrectly. These four habits fix most of the common errors.
Morning readings before food or medication, and evening readings before bed, give you the most consistent baseline. Time of day affects blood pressure significantly.
Walking, stress, caffeine, and exercise all temporarily elevate readings. The AHA recommends sitting quietly for five minutes before taking your blood pressure.
Average the two readings for the most accurate picture. If they differ by more than 5 mmHg, take a third and average all three.
An undersized cuff reads high. An oversized cuff reads low. The cuff bladder should cover 80% of your upper arm circumference. Most home monitors come with standard and large cuffs.
