A blood pressure of 110/79 is a good reading. It falls squarely in the “normal” category under the 2025 guidelines from the American Heart Association and American College of Cardiology, which define normal blood pressure as below 120/80 mmHg. Both your top number (systolic) and bottom number (diastolic) are comfortably within that range.
Where 110/79 Falls on the Chart
Blood pressure is grouped into four main categories for adults:
- 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 110/79, both numbers land in the normal zone. Your diastolic reading of 79 sits just one point below the 80 mmHg cutoff where concerns begin. If that bottom number were consistently 80 or above while your top number stayed normal, it would be classified as isolated diastolic hypertension, a condition that can raise cardiovascular risk over time. At 79, you’re on the right side of that line.
How 110/79 Compares to Truly Optimal Levels
Normal is good, but within the normal range, lower readings correlate with even better long-term outcomes. A large study analyzed by the National Heart, Lung, and Blood Institute tracked cardiovascular events like heart attacks and strokes over 10 years. Among people with systolic readings of 110 to 119 mmHg, about 4.5 per 1,000 experienced such an event. That rate dropped to 4 per 1,000 for systolic readings of 100 to 109, and just 1.3 per 1,000 for readings between 90 and 99. For comparison, people in the 120 to 129 range (still technically “normal” or “elevated”) saw 8.3 events per 1,000.
Your systolic reading of 110 puts you in a favorable spot. The difference between 110 and, say, 125 may not sound like much, but it nearly doubles the 10-year rate of cardiovascular events. So while any reading under 120/80 is classified the same way on a chart, yours is meaningfully better than a reading at the upper edge of normal.
Your Pulse Pressure Looks Fine Too
Pulse pressure is the gap between your two numbers. Yours is 31 mmHg (110 minus 79). A healthy pulse pressure is generally 40 or below, so 31 is well within the normal range. A pulse pressure consistently above 40 can signal stiffening arteries, which becomes more common with age. This isn’t something most people track, but it’s another reassuring data point in your reading.
One Reading Isn’t the Full Picture
Blood pressure fluctuates throughout the day based on what you’re doing and how you’re feeling. Physical activity, stress, caffeine, salty meals, alcohol, sleep quality, and even your body position all shift your numbers. A single reading of 110/79 is encouraging, but what matters most is your average over time.
If you’re checking at home, a few things make the reading more accurate. Avoid caffeine, exercise, and smoking for at least 30 minutes beforehand. Empty your bladder first. Sit quietly for five minutes before taking the measurement, and don’t talk or use your phone during that rest period. Place the cuff on bare skin, directly above the bend of your elbow, with your arm supported on a flat surface at heart level. Taking two or three readings a minute apart and averaging them gives a more reliable number than any single measurement.
Does Age Change What “Good” Means?
The normal threshold of below 120/80 applies to all adults regardless of age. That said, systolic pressure tends to rise as you get older because large arteries stiffen and plaque accumulates over time. For people over 50, the systolic number becomes a stronger predictor of heart disease risk than the diastolic number. A 25-year-old and a 65-year-old with the same reading of 110/79 are both in the normal category, but the older adult’s reading is especially impressive given the natural upward drift that comes with aging.
For people managing conditions like chronic kidney disease, the general target is to keep blood pressure below 140/90, though individual targets vary. A reading of 110/79 comfortably meets even the stricter targets that apply to higher-risk groups.
Keeping Your Numbers Where They Are
A normal blood pressure reading doesn’t mean it will stay that way without attention. Blood pressure tends to creep upward with age, weight gain, increased sodium intake, reduced physical activity, and chronic stress. The habits that maintain a reading like 110/79 are the same ones recommended for lowering high blood pressure: regular movement, a diet rich in fruits, vegetables, and whole grains, moderate sodium intake, limited alcohol, adequate sleep, and stress management. The advantage of starting from a healthy baseline is that small, consistent habits are usually enough to keep you there.
