A blood pressure of 111/73 is a normal, healthy reading. Both numbers fall well within the range that the American Heart Association classifies as “normal,” which is below 120 for the top number and below 80 for the bottom number. This is the most favorable category for cardiovascular health, and no treatment or lifestyle changes are needed based on this reading alone.
Where 111/73 Falls on the Chart
Blood pressure is grouped into four categories for adults:
- Normal: below 120 systolic and below 80 diastolic
- Elevated: 120 to 129 systolic and below 80 diastolic
- 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 111/73, both your systolic and diastolic numbers sit comfortably in the normal range. You’re not borderline or close to the next category. The 2025 AHA/ACC guidelines use these same thresholds, and they apply equally to adults in their 30s and adults in their 80s.
What the Two Numbers Mean
The top number (111 in your case) is your systolic pressure. It measures the force your blood exerts against artery walls when your heart pumps. The bottom number (73) is your diastolic pressure, which captures the pressure between beats while your heart refills with blood. Both numbers matter. If either one crosses into a higher category, the overall reading gets classified at that higher level.
Is It Too Low?
Some people see a number like 111/73 and wonder if it’s on the low side. It’s not. Low blood pressure, or hypotension, is generally defined as a reading below 90/60. Even then, most doctors only consider it a problem if it’s causing symptoms like dizziness, lightheadedness, blurred vision, fatigue, or fainting.
What matters more than the number itself is how you feel. A sudden drop of just 20 points in systolic pressure (say, from 110 down to 90) can cause dizziness or fainting, which is why consistency matters more than a single snapshot. If you feel fine at 111/73, there’s nothing to worry about.
For People With Diabetes or Kidney Disease
If you have diabetes or chronic kidney disease, you might be wondering whether the standard categories still apply. Current guidelines actually recommend stricter targets for these conditions, typically below 130/80. A reading of 111/73 clears that bar easily. Research in the Journal of the American Heart Association found that people with both diabetes and chronic kidney disease had a lower risk of cardiovascular problems when their blood pressure stayed below 130/80, so 111/73 puts you in a favorable position.
Making Sure Your Reading Is Accurate
A single reading is just one data point. Blood pressure fluctuates throughout the day based on stress, activity, hydration, and even the position of your body. If you’re monitoring at home, a few simple steps will make your numbers more reliable.
Avoid caffeine, tobacco, and alcohol for at least 30 minutes before measuring. Empty your bladder first. Then sit in a comfortable chair with your back supported, feet flat on the floor, and legs uncrossed for a full five minutes before taking the reading. Rest your arm on a flat surface at heart level. Letting your arm dangle at your side or propping it too high can skew the result by several points in either direction.
Taking two or three readings a minute apart and averaging them gives you a more accurate picture than relying on a single measurement. If your numbers consistently land in the normal range across multiple days and times, you can be confident the reading reflects your true blood pressure.
Keeping It in the Normal Range
Having normal blood pressure now doesn’t guarantee it will stay that way. Blood pressure tends to rise with age as arteries stiffen and lose flexibility. The habits that help maintain a healthy reading are the same ones you’ve heard before: regular physical activity, a diet that limits sodium and emphasizes fruits, vegetables, and whole grains, maintaining a healthy weight, managing stress, and limiting alcohol. These aren’t urgent interventions at 111/73. They’re the long game that keeps you from drifting into elevated territory over the next decade or two.
