What is a Normal Blood Pressure Reading?

A normal blood pressure reading typically falls within the blood pressure normal range of around 120/80 mmHg. This includes a systolic blood pressure (top number) of 120 and a diastolic blood pressure (bottom number) of 801. Blood pressure is measured using a blood pressure monitor, and readings outside the ideal range can indicate potential health issues, especially if consistently high or low.

However, blood pressure levels can vary with age, gender, and overall health. Understanding your numbers through a reliable blood pressure chart can help you make informed decisions and avoid complications like heart disease or stroke.

Blood Pressure Chart by Age and Gender

Wondering what is normal blood pressure by age or the ideal blood pressure by age? Below is a simplified blood pressure chart by age and gender to guide you:

  • Normal blood pressure for adults: 120/80 mmHg
  • What is a typical blood pressure for a 70 year old?: Around 130/80 mmHg
  • What is a normal blood pressure for a woman: Similar to men, but may trend slightly lower
  • Woman normal blood pressure by age: 110–120 systolic in younger adults, rising slightly with age

In New Zealand, what is normal blood pressure by age in NZ generally aligns with global averages, though individual health and lifestyle factors play a role2.

Interpreting Blood Pressure Readings

Here’s how to understand different blood pressure range classifications:

  • Normal: Less than 120/80
  • Elevated: Systolic between 120–129 and diastolic less than 80
  • High (Stage 1): 130–139 systolic or 80–89 diastolic
  • High (Stage 2): 140 or higher systolic or 90 or higher diastolic
  • Hypertensive crisis: Over 180/120 — this is a serious blood pressure reading and requires emergency care3

What is a stroke level blood pressure? Typically 180/120 mmHg or higher. At this point, there's a heightened risk of stroke or organ damage4.

Common Questions About Blood Pressure

Should I worry if my blood pressure is 150/80? Yes, this falls into Stage 2 hypertension and may require medication or lifestyle changes5.

Is 140 over 70 a good blood pressure reading? This is borderline high; while the diastolic is normal, the systolic is elevated.

Is 140 over 90 high blood pressure? Yes, it meets the criteria for Stage 2 hypertension and should be addressed.

What is a good BP by age? Generally 120/80 for adults under 60, and up to 130/80 for older adults.

Low Blood Pressure Concerns

Low blood pressure range is generally defined as below 90/60 mmHg. It can lead to symptoms like dizziness, fatigue, or fainting.

How low is too low for blood pressure in the elderly? For seniors, particularly those over 70, a reading below 90/60 can be dangerous and increase the risk of falls or cognitive decline6.

How to Monitor and Maintain Healthy Blood Pressure

Use a digital blood pressure monitor regularly, especially if you have a history of hypertension or other cardiovascular risks. Understanding your blood pressure reading helps you detect issues early and take action through diet, exercise, and, if necessary, medication.

Track your trends with a printed or digital blood pressure chart. Consult your GP if your blood pressure levels are consistently outside the recommended blood pressure range.

Conclusion

Maintaining blood pressure within a healthy range is essential for heart and brain health, especially as you age. Whether you're wondering what is a normal blood pressure for a woman or checking if 150/80 is too high, understanding your numbers is the first step toward better living.
