A blood pressure of 107/73 mmHg is a good reading. It falls squarely within the “normal” category, which the American Heart Association and American College of Cardiology define as a systolic (top number) below 120 and a diastolic (bottom number) below 80. It’s also comfortably above the threshold for low blood pressure, which starts below 90/60.
Where 107/73 Falls on the Scale
Current guidelines break adult blood pressure into four categories: normal, elevated, stage 1 hypertension, and stage 2 hypertension. At 107/73, both of your numbers need to be in the normal range for the overall reading to count as normal, and they are. Your systolic is 13 points below the 120 cutoff, and your diastolic is 7 points below 80.
The next category up, “elevated,” begins at 120 systolic. Stage 1 hypertension starts at 130/80. So you have a meaningful buffer before your numbers would raise any clinical concern.
What This Means for Heart Health
A systolic reading in the 100 to 109 range is associated with low cardiovascular risk. A large study of healthy adults found that cardiovascular disease events occurred at a rate of about 2.15 per 1,000 person-years for people with systolic pressures between 100 and 109, compared to 3.80 per 1,000 person-years for those in the 120 to 129 range. In other words, being on the lower end of normal is genuinely protective. The study confirmed that any systolic pressure between 90 and 129 carried no increased cardiovascular risk in otherwise healthy people.
For people with chronic kidney disease or diabetes, physicians sometimes set tighter blood pressure targets, often aiming for a systolic below 120 or 130 depending on the individual situation. A reading of 107/73 would meet those stricter goals as well.
Your Diastolic Number Is Fine
The bottom number (73) sometimes gets less attention, but it matters. Diastolic pressure below 60 is considered low and can become a concern, particularly for older adults. Research has linked diastolic readings consistently under 60 to a higher risk of heart failure over time, especially in people over 65. At 73, your diastolic is well within the healthy zone and nowhere near that threshold.
When a Normal Reading Could Still Cause Symptoms
Blood pressure is personal. What’s normal on paper can still feel off if it represents a sudden drop from your usual level. A shift of just 20 mmHg in either direction can cause dizziness or faintness. So if you typically run around 130 and suddenly measure 107, you might feel lightheaded even though the number itself is healthy.
Symptoms worth paying attention to include blurred or fading vision, persistent dizziness, fatigue, or fainting. If 107/73 is your usual baseline and you feel fine, there’s nothing to worry about. If these symptoms show up regularly, the reading itself isn’t the problem, but something driving a change in your pressure might be.
Making Sure Your Reading Is Accurate
A single reading can be misleading. To confirm that 107/73 reflects your true resting blood pressure, the CDC recommends a few steps. Avoid food, drinks, and caffeine for 30 minutes beforehand. Empty your bladder. Sit with your back supported and both feet flat on the floor for at least five minutes before measuring. Rest the cuffed arm on a table at chest height, with the cuff snug against bare skin. Don’t talk during the reading.
Take at least two readings one to two minutes apart and average them. If both come back near 107/73, you can be confident the number is real. Home monitors are reliable when used correctly, but it’s worth comparing your device to a reading at your doctor’s office occasionally to make sure they agree.
The Bottom Line on 107/73
This is a healthy blood pressure by every current standard. It sits in the normal range, carries low cardiovascular risk, and keeps both numbers well clear of the thresholds for high or low blood pressure. If you’re seeing this number consistently and feeling well, your blood pressure is doing exactly what you’d want it to do.
