A blood pressure of 111/65 is a good reading. It falls squarely in the “normal” category, which the American Heart Association defines as a systolic (top number) below 120 and a diastolic (bottom number) below 80. Both of your numbers clear those thresholds comfortably, and neither is low enough to raise concerns about hypotension.
Where 111/65 Falls on the Scale
The 2025 guidelines from the American Heart Association and American College of Cardiology break adult blood pressure into four categories:
- Normal: below 120 systolic and below 80 diastolic
- Elevated: 120 to 129 systolic with diastolic still below 80
- Stage 1 hypertension: 130 to 139 systolic or 80 to 89 diastolic
- Stage 2 hypertension: 140 or higher systolic or 90 or higher diastolic
At 111/65, you’re well within normal range. You’re also above the threshold for low blood pressure, which is generally considered to be below 90/60. Your diastolic of 65 sits above the 60 cutoff that some clinicians use to flag a low bottom number.
What Your Pulse Pressure Tells You
Pulse pressure is the gap between your top and bottom numbers. For a reading of 111/65, that’s 46. A healthy pulse pressure generally falls around 40, and readings above 60 become a risk factor for heart disease, particularly in older adults. At 46, yours is in a healthy range, suggesting your arteries have good elasticity and your heart is pumping blood effectively.
Why This Reading Can Vary
A single blood pressure reading is a snapshot, not a verdict. Small changes in how you take the measurement can shift both numbers by several points. A 2024 trial published in JAMA Internal Medicine found that resting your arm on your lap instead of a desk at heart level inflated systolic readings by about 4 points and diastolic by 4 points. Letting your arm hang unsupported at your side was even worse, adding roughly 6.5 points to the top number and 4.4 to the bottom.
The physics behind this are straightforward: when your arm drops below heart level, gravity increases pressure in the artery being measured. Your blood vessels also constrict slightly to compensate for reduced blood flow back to the heart, and holding your arm up without support tenses muscles, which temporarily raises pressure further. For the most accurate reading, sit with your back supported, feet flat on the floor, and your arm resting on a table with the middle of the cuff at heart level.
How Age Affects Interpretation
Blood pressure naturally tends to creep upward with age. Large arteries stiffen over time, plaque builds up, and the heart works harder to push blood through. For people over 50, the systolic number becomes especially important as a predictor of cardiovascular risk. A reading of 111/65 in a 25-year-old is typical. The same reading in a 70-year-old is excellent and suggests the cardiovascular system is aging well.
People who stay physically active tend to maintain lower blood pressure into middle and older age. Research on competitive master athletes (recreational and competitive athletes over 35) found their systolic pressure was about 8% lower and diastolic about 4% lower than the general population. Only about 8% of those athletes had hypertension, compared to 17% in the general population. If you exercise regularly, a reading like 111/65 is right in line with what fitness does for your cardiovascular system.
During Pregnancy
If you’re pregnant and wondering about this number, 111/65 is reassuring. Normal blood pressure during pregnancy is 120/80 or lower, and high blood pressure in pregnancy is defined as 140/90 or above on two separate occasions after 20 weeks. Your reading is well within the healthy zone for both you and your baby.
When a Low-Normal Reading Deserves Attention
A reading of 111/65 is not low blood pressure. But if your numbers regularly sit at the lower end of normal and you experience symptoms, those symptoms matter more than the numbers themselves. Most healthcare professionals only consider blood pressure “too low” when it causes problems like dizziness, lightheadedness, blurred vision, fatigue, trouble concentrating, or fainting.
Sudden drops are more concerning than consistently low readings. A change of just 20 points in systolic pressure, say from standing up quickly, can cause dizziness or fainting even if the absolute number isn’t technically in the low range. If you feel fine at 111/65, there’s nothing to worry about. If you’re experiencing any of those symptoms regularly, the pattern is worth mentioning at your next appointment, since the issue may not be the blood pressure itself but what’s causing the drop.
