A blood pressure of 107/63 is a good reading. It falls squarely within the normal range, which the American Heart Association defines as below 120/80 mm Hg. Both your systolic number (107, the top number) and your diastolic number (63, the bottom number) are well within healthy limits, and neither is low enough to qualify as hypotension.
Where 107/63 Falls on the Scale
Blood pressure readings are grouped into categories based on two thresholds. The normal range sits between 90/60 and 120/80 mm Hg. Anything below 90/60 is considered low blood pressure (hypotension), while readings above 120/80 start moving into elevated and eventually high blood pressure territory. At 107/63, you’re comfortably in the middle of the normal zone, closer to the lower end but not near the cutoff for concern.
The key distinction here is that lower blood pressure is generally better, as long as you feel fine. High blood pressure is the reading that damages blood vessels, strains the heart, and raises the risk of stroke and heart disease over time. A reading like 107/63 means your cardiovascular system isn’t working under excess pressure, which is exactly what you want.
Why Some People Run on the Lower Side
If 107/63 feels surprisingly low to you, it helps to know that plenty of healthy people sit in this range all the time. Physically active individuals often have lower resting blood pressure because their hearts pump more efficiently. Research on young athletes shows they tend to have lower diastolic pressure than non-athletes, a result of greater cardiac output paired with flexible arteries and low resistance in their blood vessels. This isn’t a problem. It’s a sign of cardiovascular fitness.
Pregnancy can also shift blood pressure downward. In clinically healthy pregnant women, blood pressure typically drops in early pregnancy compared to pre-pregnancy levels, then gradually rises back to baseline by late pregnancy. So if you’re pregnant and seeing numbers like 107/63, that pattern is expected. Women who started with higher pre-pregnancy blood pressure tend to experience a bigger early drop, while those who already ran low may not notice much change at all.
When a Low-Normal Reading Matters
The number on the cuff only becomes a concern when it comes with symptoms. Low blood pressure that causes dizziness, lightheadedness, blurred or fading vision, fainting, or persistent fatigue deserves attention, because those symptoms mean your brain and organs may not be getting enough blood flow. This typically happens at readings below 90/60, not at 107/63, but individual thresholds vary.
The pattern matters more than any single reading. If your blood pressure has dropped suddenly from a higher baseline, that shift could signal something worth investigating, even if the number itself looks normal on paper. A gradual, stable reading of 107/63 with no symptoms is a completely different situation from a sudden plunge to that level. If you consistently feel fine at this reading, no treatment or lifestyle change is needed.
Getting an Accurate Reading at Home
If you’re checking your blood pressure at home and want to trust the number, technique matters more than most people realize. The CDC recommends sitting in a comfortable chair with your back supported for at least five minutes before taking a reading. Both feet should be flat on the floor with your legs uncrossed. Rest the arm wearing the cuff on a table at chest height.
A few smaller details can throw off results: the cuff should sit against bare skin, not over clothing, and it should be snug without being tight. Don’t eat, drink, or use the bathroom right before measuring. Avoid talking during the reading. These steps sound minor, but skipping them can shift your numbers by several points in either direction, which is enough to push a reading into a different category entirely.
Taking two or three readings a minute apart and averaging them gives you a more reliable picture than relying on a single measurement. Blood pressure fluctuates throughout the day based on stress, activity, caffeine, and even the temperature of the room, so a one-time snapshot is just that.
What Your Numbers Actually Mean
The top number (systolic) measures the pressure in your arteries when your heart beats. The bottom number (diastolic) measures the pressure between beats, when your heart is resting. Both numbers matter independently. Your systolic reading of 107 is 13 points below the upper limit of normal, and your diastolic reading of 63 is 17 points above the hypotension threshold. That gives you a comfortable margin on both ends.
Current guidelines from major health organizations don’t set different blood pressure targets based on age for most adults. Older guidelines used to allow higher readings for people over 65, but that approach has largely been replaced by a single standard. So whether you’re 25 or 70, 107/63 is a healthy reading as long as it isn’t causing symptoms. It’s the kind of number that reflects a heart doing its job without overworking.
