Understanding Your Reading
Blood pressure is written as systolic over diastolic, for example 120/80 mmHg. The systolic number is the pressure when your heart contracts; the diastolic is the pressure between beats. The American Heart Association defines five categories: Normal (below 120/80), Elevated (120-129 systolic with diastolic below 80), Stage 1 hypertension (130-139 systolic or 80-89 diastolic), Stage 2 hypertension (140+ systolic or 90+ diastolic), and Hypertensive crisis (above 180/120), which needs immediate medical attention.
Enter your two numbers and the checker places your reading in the right category, computes your pulse pressure (systolic minus diastolic, normally 30 to 50), and tells you what to do next. A single reading is a snapshot, not a diagnosis: blood pressure moves through the day with stress, caffeine, exercise, and even talking during the measurement.
How to Take an Accurate Reading
Sit with your back supported and feet flat, rest five minutes first, and keep your arm supported at heart level. Avoid caffeine, exercise, and smoking for 30 minutes beforehand, and empty your bladder. Do not talk during the measurement. Take two readings a minute apart and average them. Home cuffs should be validated and the right cuff size for your arm; a cuff that is too small reads artificially high.
When to See a Doctor
See your doctor if readings are consistently at or above 130/80, which is the threshold for stage 1 hypertension. Track a week of morning and evening readings and bring the log. Seek emergency care for any reading above 180/120, especially with chest pain, shortness of breath, back pain, numbness, vision changes, or trouble speaking. One high reading after stress or caffeine is usually not an emergency; a pattern of high readings is what matters.
Lowering Blood Pressure Naturally
The DASH eating pattern, less sodium (aim under 2,300 mg daily), 150 minutes of weekly moderate exercise, limiting alcohol, quitting smoking, keeping a healthy weight, and managing stress all lower blood pressure measurably. Losing even 5 to 10 pounds can drop systolic pressure several points. These steps work alongside, not instead of, any medication your doctor prescribes.

Frequently Asked Questions
What is a normal blood pressure reading?
Below 120/80 mmHg is normal by AHA standards. Readings of 120-129 systolic with diastolic under 80 are elevated, 130-139 or 80-89 is stage 1 hypertension, and 140/90 or higher is stage 2.
Why is my first reading always higher?
The first reading catches your body before it fully settles. Sit quietly for five minutes, take two readings a minute apart, and average them. Talking, a full bladder, crossed legs, or an unsupported arm can each add several points.
What is pulse pressure?
Systolic minus diastolic. Normal is 30 to 50 mmHg. A consistently wide pulse pressure (above 60) can signal stiff arteries and is worth mentioning to your doctor, especially in older adults.
Can anxiety raise blood pressure?
Yes, sharply and temporarily. White-coat hypertension is real: readings at the clinic run higher than at home for many people. That is why doctors ask for a week of home readings before diagnosing hypertension.
When is high blood pressure an emergency?
Above 180/120 is a hypertensive crisis. Get emergency care, especially with chest pain, shortness of breath, back pain, numbness or weakness, vision changes, or difficulty speaking.
