A blood pressure of 116/63 falls in the normal category. Your systolic number (116) is comfortably below the 120 threshold, and your diastolic number (63) is well under 80. By the 2025 AHA guidelines, normal blood pressure is defined as below 120/80, and your reading clears both numbers. That said, there are a couple of nuances worth understanding, particularly around your diastolic number and the gap between your two numbers.
Where 116/63 Falls on the Chart
The American Heart Association breaks adult blood pressure into four categories:
- Normal: below 120 systolic and below 80 diastolic
- Elevated: 120 to 129 systolic and below 80 diastolic
- Hypertension Stage 1: 130 to 139 systolic or 80 to 89 diastolic
- Hypertension Stage 2: 140 or higher systolic or 90 or higher diastolic
At 116/63, both numbers land in the normal range. The recommendation for people in this category is simply to maintain a healthy lifestyle. You’re not in elevated territory, and you’re nowhere near hypertension.
Why Your Diastolic Number Is Worth Watching
A diastolic reading of 63 is normal, but it sits close to the line where some clinicians start paying closer attention. Diastolic blood pressure is generally considered low at 60 or below. At 63, you’re just above that threshold.
Low blood pressure overall is defined as anything under 90/60. Your reading doesn’t meet that definition, since your systolic number is well above 90. But diastolic pressure specifically matters because it reflects the pressure in your arteries between heartbeats, which is when your heart muscle receives its own blood supply. Research from the AHA has found that very low diastolic pressure, particularly in older adults with stiff arteries, can reduce blood flow to the heart during that resting phase.
For younger, healthy, and physically active people, a diastolic number in the low 60s is common and typically harmless. Athletes and people who exercise regularly often have lower resting blood pressure across the board. If you feel fine, a diastolic of 63 is not a concern. If you consistently see it dropping into the mid-to-low 50s, or you develop symptoms, that’s a different picture.
Your Pulse Pressure Is Slightly Wide
Pulse pressure is the difference between your top and bottom numbers. For 116/63, that’s 53. A healthy pulse pressure is around 40, and readings above 60 start to become a risk factor for heart disease, especially in older adults.
At 53, yours is slightly above the ideal but well below the concerning range. A wider pulse pressure often reflects stiffer arteries, which happens naturally with age. In a younger person, it can simply reflect a strong, efficient heartbeat pushing out a good volume of blood. One reading of 53 is not something to worry about, but if your pulse pressure trends upward over years (toward 60 or beyond), it’s worth discussing at a routine checkup.
Symptoms That Would Change the Picture
Most health professionals consider blood pressure “too low” only when it causes symptoms. A reading of 116/63 that feels perfectly fine is a good reading, full stop. But if you’re experiencing any of the following regularly, your blood pressure (or specifically your diastolic pressure) may be running too low for your body:
- Dizziness or lightheadedness, especially when standing up
- Blurred or fading vision
- Persistent fatigue
- Trouble concentrating
- Fainting or near-fainting episodes
- Nausea
These symptoms don’t automatically point to blood pressure as the cause, but they’re worth mentioning if you notice them alongside readings where your diastolic keeps dipping into the low 60s or below.
One Reading vs. a Pattern
Blood pressure fluctuates throughout the day. It rises when you’re stressed, exercising, or even just talking, and it drops when you’re relaxed or sleeping. A single reading of 116/63 is a snapshot, not a diagnosis. Some people consistently get different numbers at home versus in a medical office.
If you’re checking at home, make sure your monitor is accurate by comparing it against the equipment at your next appointment. For a reliable picture, take readings at the same time of day, sitting quietly for five minutes beforehand, with your arm supported at heart level. A pattern across multiple readings over days or weeks tells you far more than any single number. If your readings consistently cluster around 116/63, you’re sitting in a healthy range with a diastolic worth keeping an eye on as you age.
