A blood pressure of 107/64 mmHg is a good reading. It falls squarely in the “normal” category, which is defined as a systolic (top number) below 120 and a diastolic (bottom number) below 80. Both of your numbers sit comfortably within that range, and readings like this are associated with lower cardiovascular risk over time.
Where 107/64 Falls on the Scale
Blood pressure is grouped into five categories based on guidelines from the American Heart Association and the American College of Cardiology:
- Normal: below 120 systolic and below 80 diastolic
- Elevated: 120 to 129 systolic and below 80 diastolic
- High blood pressure, Stage 1: 130 to 139 systolic or 80 to 89 diastolic
- High blood pressure, Stage 2: 140 or higher systolic or 90 or higher diastolic
- Hypertensive crisis: above 180 systolic or above 120 diastolic
At 107/64, you’re not just under the threshold for elevated blood pressure. You’re well within normal range with room to spare. This is the kind of reading most people are trying to achieve or maintain through lifestyle changes.
What the Two Numbers Mean
The top number (107 in your case) is systolic pressure, which is the peak force in your arteries when your heart contracts and pushes blood out. The bottom number (64) is diastolic pressure, the lowest point of pressure between beats when your heart relaxes and refills with blood. Both numbers matter. A reading is only classified as normal when both the systolic and diastolic values fall within the healthy range.
Why This Reading Is Protective
Lower blood pressure within the normal range doesn’t just mean the absence of a problem. It actively reduces your risk of heart attack, stroke, and other cardiovascular events. A large analysis of blood pressure treatment trials found that every 5 mmHg reduction in systolic blood pressure cuts the risk of major cardiovascular events by about 10%, and this benefit holds even for people who already have readings below 120. In other words, a systolic of 107 carries meaningfully less cardiovascular risk than a systolic of 119, even though both are technically “normal.”
This is one of the reasons doctors and public health organizations encourage people to keep blood pressure as low as possible within the normal range, rather than simply aiming to stay below the cutoff for high blood pressure.
Is 107/64 Too Low?
Blood pressure is generally considered too low (hypotension) when it drops below 90/60 mmHg. Your reading of 107/64 is well above that threshold. Most health professionals only consider lower blood pressure a concern when it causes symptoms, not based on the number alone.
That said, if you regularly feel dizzy when standing up, lightheaded, unusually fatigued, or like you might faint, it’s worth paying attention. These can be signs of orthostatic hypotension, which is diagnosed when your systolic pressure drops by at least 20 mmHg or your diastolic drops by at least 10 mmHg within three minutes of standing up. This is about the change in pressure when you shift positions, not your resting number. Someone with a resting reading of 107/64 who feels perfectly fine standing and moving around has nothing to worry about.
How It Compares Across Ages
Blood pressure naturally rises with age as arteries stiffen. For context, a typical 10-year-old has average blood pressure around 102/61. By age 17, average readings climb to about 118/67 for boys and 111/66 for girls. In adults, the healthy target remains below 120/80 regardless of age, though many adults see their blood pressure creep upward over the decades.
A reading of 107/64 in a young adult is entirely expected. In a middle-aged or older adult, it’s a sign that your cardiovascular system is in good shape. Either way, it’s a healthy number.
Keeping Your Blood Pressure in This Range
If your blood pressure is already at 107/64, the goal is maintenance. The habits that keep blood pressure low are the same ones that support overall health: regular physical activity, a diet rich in fruits, vegetables, and whole grains while lower in sodium, maintaining a healthy weight, limiting alcohol, and managing stress. These factors have a cumulative effect. People who maintain normal blood pressure through their 40s, 50s, and beyond have significantly lower lifetime risk of heart disease and stroke compared to those whose pressure gradually rises into the elevated or high categories.
A single blood pressure reading is a snapshot. If you took this reading at home, try checking it a few times over the course of a week at roughly the same time of day, sitting quietly for five minutes beforehand. Consistency across multiple readings is more informative than any single measurement.
