A blood pressure log helps you track systolic and diastolic readings over time to identify trends and communicate results with your healthcare provider. Regular home monitoring can detect hypertension earlier than office visits alone.

How to Use the Blood Pressure Log
This blood pressure log helps you track readings over time, calculate averages, and identify trends. Enter systolic (top number), diastolic (bottom number), and optional pulse for each reading.
Tips for Accurate Home Monitoring
For reliable readings: sit quietly for 5 minutes before measuring, keep your feet flat on the floor and arm at heart level, avoid caffeine and exercise for 30 minutes prior, and take measurements at consistent times each day. Two readings per day (morning and evening) for 7 days gives your doctor the best picture.
Interpreting Your Results
The AHA defines normal blood pressure as below 120/80 mmHg. A single high reading is not a diagnosis — white coat hypertension (elevated in a medical setting) and masked hypertension (normal in-office, elevated at home) both exist. Share your log with your healthcare provider for proper interpretation.
Frequently Asked Questions
Is this blood pressure log free?
Yes, completely free with no signup required. Your readings are stored locally in your browser.
What is normal blood pressure?
Normal blood pressure is less than 120/80 mmHg. Stage 1 hypertension is 130-139/80-89 mmHg. Stage 2 hypertension is 140+/90+ mmHg. Hypertensive crisis is above 180/120 mmHg.
How often should I take my blood pressure?
For home monitoring, check twice daily — morning before medications and evening — for at least a week. Always rest for 5 minutes before measuring. Avoid caffeine and exercise for 30 minutes beforehand.
What is pulse pressure?
Pulse pressure is the difference between systolic and diastolic readings. A normal pulse pressure is 40 mmHg. Wide pulse pressure (>60 mmHg) can indicate arterial stiffness; narrow pulse pressure (<25 mmHg) may signal heart problems.
What is the difference between systolic and diastolic pressure?
Systolic pressure (top number) is the force when your heart beats. Diastolic pressure (bottom number) is the force between beats. Both numbers matter — isolated systolic hypertension (high systolic with normal diastolic) is common in older adults.
