# How to Choose a Home Blood Pressure Monitor

> A practical buying guide to home blood pressure monitors: why upper-arm beats wrist, why cuff size matters most, which features are worth it, and how to validate accuracy.

Choosing a home blood pressure monitor comes down to a few decisions that actually affect your readings — and a lot of features that don't. This guide walks through what matters so you end up with a device you trust and will actually use.

<Note>
  A home monitor is a tracking tool, not a diagnosis. Hypertension is diagnosed and treated by a clinician using readings over time — never start, stop, or change medication based on home numbers alone.

## Upper-arm or wrist?

For most people, a validated **upper-arm cuff monitor is the better choice**. Upper-arm devices are generally more accurate and repeatable than wrist or fingertip models, which are sensitive to arm position and motion. Wrist monitors have a place for people who genuinely cannot use an arm cuff, but they require careful positioning at heart level. See our deeper comparison of [upper-arm vs. wrist](/blood-pressure/upper-arm-vs-wrist).

## Why is cuff size the most important factor?

Cuff size affects accuracy more than almost anything else: a cuff that is too small reads falsely high, and one too large reads falsely low. Measure your upper-arm circumference and confirm it falls within the device's cuff range before buying, and look for a large-cuff option if you have bigger arms. Our [cuff size and accuracy guide](/blood-pressure/cuff-size-and-accuracy) explains how to measure correctly.

## Which features are worth paying for?

A handful of features genuinely help: an **automatic (digital) one-button design**, a **clear, large display**, **reading memory or averaging** so you can track trends, and an **irregular-heartbeat indicator** that flags a possibly uneven pulse. Multi-user memory is useful when a household shares one device. Bluetooth and apps are convenient but optional — a simple, validated monitor used consistently beats a fancy one you find fiddly.

## How do I know a monitor is accurate?

Look for a monitor that has been clinically validated, then sanity-check it yourself: bring it to a checkup and compare a home reading on the same arm to the clinic's. Readings within roughly 5–10 mm Hg suggest it is tracking well. Remember that [technique](/blood-pressure/how-to-measure-at-home) — resting first, sitting correctly, arm at heart level — affects accuracy as much as the device.

## How SonoHealth fits

SonoHealth offers the **BPpro** and **BPMAX** upper-arm home blood pressure monitors, designed for simple, repeatable at-home readings. Whichever monitor you choose, confirm the cuff fits, use it the same way each time, and share your trend with your doctor. You can see both at [SonoHealth.com](https://sonohealth.com/shop/).

## When to involve your doctor

Contact your doctor if your readings are consistently high, if you see an irregular-heartbeat flag, or if anything changes. Treat a reading at or above 180/120 with symptoms as a medical emergency — call 911.
