A blood pressure of 108/76 is a good reading. It falls squarely within the normal category, which the American Heart Association defines as below 120/80 mmHg. Both your systolic pressure (108, the top number) and your diastolic pressure (76, the bottom number) are comfortably under those thresholds, placing you in the healthiest blood pressure range.
Where 108/76 Falls on the Scale
Blood pressure is classified into distinct categories. Normal is anything below 120/80. Elevated blood pressure starts at 120-129 systolic with a diastolic still under 80. Stage 1 hypertension begins at 130/80, and Stage 2 at 140/90. At the other end, low blood pressure (hypotension) is generally defined as a reading below 90/60.
At 108/76, you’re well above the hypotension threshold and well below the elevated range. This is essentially the sweet spot. A meta-analysis of nearly 40,000 adults found that people who maintained systolic pressure below 120 had a 13% lower risk of dying from any cause compared to those with higher readings. Every 5 mmHg reduction in systolic pressure is associated with roughly a 10% drop in the risk of major cardiovascular events like heart attack, stroke, and heart failure.
What About Pulse Pressure?
Pulse pressure is the gap between your top and bottom numbers. For 108/76, that’s 32 mmHg. A normal pulse pressure is around 40 mmHg, so yours is on the lower side. However, a pulse pressure only becomes concerning when it drops to one-quarter or less of the systolic number. One-quarter of 108 is 27, and your pulse pressure of 32 clears that cutoff. A slightly narrow pulse pressure at this reading is not a red flag on its own.
When a Normal Reading Could Still Be a Problem
Blood pressure numbers only tell part of the story. What matters just as much is how you feel. Some people naturally run lower than average and feel perfectly fine at 108/76 or even lower. Others might experience symptoms at the same reading, especially if their blood pressure dropped from a higher baseline.
Symptoms worth paying attention to include persistent dizziness or lightheadedness, feeling unusually tired or sluggish, difficulty concentrating, or feeling faint when standing up. These can signal that your body isn’t circulating blood effectively, even when the numbers technically look normal. If you consistently feel fine, a reading of 108/76 is simply good news.
108/76 During Pregnancy
If you’re pregnant and seeing this number, it’s reassuring. The American College of Obstetricians and Gynecologists uses the same threshold as the general population: normal is below 120/80. Blood pressure naturally dips during the first and second trimesters before rising again in the third, so a reading of 108/76 is typical and healthy during pregnancy. The bigger concerns during pregnancy are readings that climb above 140/90, which can signal preeclampsia or gestational hypertension.
How to Make Sure Your Reading Is Accurate
A single reading can be thrown off by surprisingly small things. The American Heart Association recommends a specific routine for home monitoring to get reliable numbers. Avoid caffeine, smoking, and exercise for at least 30 minutes beforehand. Empty your bladder, then sit quietly for five minutes before measuring. Don’t talk or look at your phone during that rest period.
When you do take the reading, sit with your back supported and your feet flat on the floor. Place the cuff on your bare upper arm (not over clothing) so the middle of the cuff sits at heart level. Propping your arm on a table or pillow helps with this. If your arm hangs at your side or you measure through a sleeve, you can get a reading that’s off by several points in either direction.
Taking two or three readings a minute apart and averaging them gives you the most accurate picture. If you’re tracking your blood pressure over time, measuring at the same time each day helps you spot real trends rather than normal daily fluctuations.
How 108/76 Compares Across Ages
Blood pressure naturally changes throughout life. For context, the median blood pressure for a 15-year-old boy is around 113/64, while for a 15-year-old girl it’s about 110/65. Adults tend to see gradual increases with age as blood vessels lose some of their elasticity. A reading of 108/76 in a young adult is completely typical. In an older adult, it suggests well-maintained cardiovascular health, likely supported by regular physical activity, a balanced diet, or favorable genetics.
Regardless of your age, maintaining blood pressure in this range is one of the strongest protections against heart disease, stroke, and kidney damage over the long term. If 108/76 is your baseline, the goal is simply to keep it there.
