A blood pressure of 116/78 is a good reading. It falls squarely within the “normal” category, which the American Heart Association defines as below 120/80 mmHg. Both your top number (116) and bottom number (78) need to be under those thresholds to qualify as normal, and yours clear both.
Where 116/78 Falls on the Scale
The 2025 AHA/ACC guidelines break adult blood pressure into four categories:
- 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 116/78, you’re in the normal range but close to the upper boundary on both numbers. A systolic increase of just 4 points would push you into the “elevated” category, and a diastolic increase of 2 points would tip you into stage 1 hypertension. That doesn’t mean you’re at risk right now. It just means this is a reading worth maintaining rather than ignoring.
What the Two Numbers Mean
The first number, 116, is your systolic pressure. It measures the force your blood exerts against artery walls each time your heart beats and pushes blood out. The second number, 78, 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.
How 116/78 Relates to Heart Disease Risk
Large-scale analyses have found a linear relationship between systolic blood pressure and the risk of cardiovascular disease and death, with the lowest risk observed at systolic readings between 120 and 124 mmHg. Your reading of 116 sits just below that range, which is excellent. For people who already have hypertension, current guidelines encourage lowering systolic pressure to below 120 mmHg when possible. Being there naturally, without medication, puts you in a favorable position.
There is also a floor. Blood pressure below 90/60 is generally considered low (hypotension) and can cause dizziness, fatigue, blurred vision, and fainting. A drop of just 20 points in systolic pressure can be enough to trigger symptoms. At 116/78, you’re well above that threshold.
Why a Single Reading Isn’t the Full Picture
Blood pressure fluctuates throughout the day. Stress, caffeine, a full bladder, or even talking during a reading can push numbers higher. In clinical settings, the difference between a reading taken by a physician versus a nurse has been documented at up to 30 mmHg in some studies, a phenomenon tied to what’s known as white-coat hypertension, where anxiety in a medical setting inflates the result.
The reverse also happens. Some people have normal readings in the office but higher numbers at home, called masked hypertension. This is why a pattern of readings over time is more meaningful than any single measurement. If 116/78 is typical for you across multiple readings, that’s reassuring. If it was a one-time check, it’s worth confirming with a few more measurements at home.
Getting an Accurate Reading at Home
If you want to track your blood pressure, technique matters more than most people realize. The CDC recommends avoiding food, drinks, and caffeine for 30 minutes before measuring. Empty your bladder first. Sit with your back supported and both feet flat on the floor for at least five minutes before taking a reading. Rest your arm on a table so the cuff sits at chest height, and place the cuff on bare skin rather than over a sleeve. Keep your legs uncrossed, and don’t talk during the measurement.
Small deviations from this routine can shift your numbers by several points in either direction. Taking two or three readings a minute apart and averaging them gives you the most reliable result. Tracking these numbers over a few weeks will tell you far more about your cardiovascular health than a single reading at a pharmacy kiosk or doctor’s office.
Keeping Your Numbers Where They Are
A normal reading today doesn’t guarantee a normal reading in five years. Blood pressure tends to creep upward with age, particularly the systolic number. Regular physical activity, maintaining a healthy weight, limiting sodium, and managing stress are the most effective ways to keep your numbers from drifting into elevated territory. At 116/78, you’re not treating a problem. You’re protecting an advantage.
