# What Is a Normal Blood Pressure Reading?

> What counts as normal, elevated, and high blood pressure using American Heart Association categories, plus how age, time of day, and technique affect your numbers.

Blood pressure is one of the simplest and most informative numbers you can track at home — but knowing what's "normal" requires understanding the categories clinicians actually use, not just a single target.

<Note>
  These categories are general guidance based on American Heart Association definitions. Your personal targets may differ depending on age, pregnancy, and health conditions, so confirm them with your doctor. A single high reading is not a diagnosis.

## Blood pressure categories for adults

| Category             | Systolic (top)  |        | Diastolic (bottom) |
| -------------------- | --------------- | ------ | ------------------ |
| Normal               | Below 120       | and    | Below 80           |
| Elevated             | 120–129         | and    | Below 80           |
| Hypertension Stage 1 | 130–139         | or     | 80–89              |
| Hypertension Stage 2 | 140 or higher   | or     | 90 or higher       |
| Hypertensive crisis  | Higher than 180 | and/or | Higher than 120    |

A reading in the **normal** range (under 120/80) is the goal for most adults. **Elevated** isn't hypertension yet, but it's a signal to focus on heart-healthy habits. A **hypertensive crisis** reading needs urgent attention — see [when a reading is an emergency](/blood-pressure/high-blood-pressure-when-to-worry).

## Does normal blood pressure change with age?

Blood pressure does tend to rise with age, in part because arteries stiffen over time. However, the categories above apply to adults in general — "normal" doesn't get a free pass to be higher just because you're older. Older adults sometimes have individualized targets set by their doctor, which is another reason to interpret your numbers with your care team rather than against a single universal cutoff.

## Why your reading varies through the day

Blood pressure naturally dips overnight and rises around waking (the "morning surge"), and it shifts with stress, caffeine, a full bladder, talking, temperature, and arm position. This is why one number tells you little and a **trend** tells you a lot. Measuring at the same times each day — and using correct [technique](/blood-pressure/how-to-measure-at-home) — gives the clearest picture.

## What about pulse?

Most home monitors, including SonoHealth's BPpro and BPMAX, also show your pulse. A normal adult resting heart rate is roughly 60–100 beats per minute. A consistently very high, very low, or irregular pulse is worth raising with your doctor — and an irregular rhythm may warrant a closer look with an [EKG](/ekg/overview).
