A blood pressure of 110/68 mmHg is a good reading. It falls squarely in the “normal” category, which the American Heart Association defines as below 120/80 mmHg. You’re well within the healthy range on both numbers, with comfortable margin before reaching “elevated” territory.
Where 110/68 Falls on the Scale
Current guidelines break blood pressure into four categories:
- Normal: below 120 systolic and below 80 diastolic
- Elevated: 120 to 129 systolic and below 80 diastolic
- Hypertension Stage 1: 130 to 139 systolic or 80 to 89 diastolic
- Hypertension Stage 2: 140 or higher systolic or 90 or higher diastolic
At 110/68, both your numbers are normal. The top number (systolic) reflects pressure in your arteries when your heart beats. The bottom number (diastolic) reflects pressure between beats, when your heart is resting. Neither number needs to be lower, and neither is close to a concerning threshold in either direction.
Not Too Low Either
Some people worry that a diastolic reading in the 60s might be too low. It isn’t. Low blood pressure, or hypotension, is generally defined as a reading below 90/60 mmHg. Your 110/68 sits comfortably above that line.
Even readings that technically qualify as low aren’t a problem unless they cause symptoms. Signs of genuinely low blood pressure include dizziness, fainting, blurred vision, nausea, fatigue, and difficulty concentrating. If you feel fine at 110/68, there’s nothing to address.
What Your Pulse Pressure Tells You
The gap between your top and bottom numbers is called pulse pressure. For a reading of 110/68, that’s 42 mmHg. A normal pulse pressure is around 40, so yours is right on target. This gap reflects how elastic and flexible your arteries are. A very wide gap (60 or more) can signal stiff arteries, while a very narrow one (less than one-quarter of the top number, which would be about 28 in your case) can indicate other cardiovascular issues. At 42, your arteries are doing their job well.
How Sex and Age Factor In
The current guidelines apply the same blood pressure categories to all adults regardless of age. There’s no separate “normal” for older adults or younger ones.
Sex does play a subtle role, though. Research from the National Heart, Lung, and Blood Institute found that women may face increased cardiovascular risk at lower blood pressure levels than men. In a study of more than 27,000 adults, heart attack risk for women began climbing in the 110 to 119 systolic range, while for men it didn’t rise until 150 to 159. This doesn’t mean 110 systolic is dangerous for women. It means that even within the “normal” range, the relationship between blood pressure and risk isn’t identical across sexes, and maintaining a healthy lifestyle still matters even with a good reading.
Making Sure Your Reading Is Accurate
A single blood pressure reading is a snapshot, not the full picture. Blood pressure fluctuates throughout the day based on stress, caffeine, physical activity, and even whether you need to use the bathroom. To know whether 110/68 truly represents your baseline, the CDC recommends a consistent measuring routine:
- Rest first. Sit with your back supported for at least five minutes before measuring.
- Avoid food, drinks, and caffeine for 30 minutes beforehand.
- Empty your bladder before you start.
- Position yourself correctly. Both feet flat on the floor, legs uncrossed, arm resting on a table at chest height.
- Use bare skin. Place the cuff directly on your arm, not over clothing.
- Stay quiet. Don’t talk during the measurement.
- Take two readings about one to two minutes apart and note both.
If you consistently see readings near 110/68 under these conditions, you can feel confident that your blood pressure is genuinely in a healthy place. Occasional readings that are a bit higher or lower are perfectly normal and expected.
Keeping It There
Normal blood pressure doesn’t stay normal on its own forever. Blood pressure tends to creep upward with age, weight gain, increased sodium intake, and reduced physical activity. The same habits that help lower high blood pressure also help maintain a good reading: regular exercise, a diet rich in fruits, vegetables, and whole grains, moderate sodium intake, limited alcohol, and adequate sleep. At 110/68, you’re not trying to fix a problem. You’re protecting an advantage.
