Best blood pressure monitors for large arms
A cuff that’s too small squeezes harder and reads falsely high. If your upper arm is over about 42 cm, you need a wide-range cuff or an XL — here’s what genuinely fits.
Measure your upper arm at the midpoint between shoulder and elbow, relaxed. Most “standard” cuffs top out around 42 cm. Above that, you have two options: a monitor with an extra-wide built-in cuff, or an Omron/Greater Goods unit plus a separately-sold XL cuff.
The widest built-in cuff in our list reaches 48 cm, which covers the large majority of larger arms without a separate purchase.
Worth knowing: Greater Goods and Omron sell XL cuffs separately that push their range well past 42 cm — often cheaper than buying a different monitor. Confirm the XL part number for your exact model.
Our picks
Best for large arms iHealth Track
The answer when a standard cuff won’t close: a 48 cm range, a big backlit screen and a tidy app, for budget money. It’s validated by STRIDE BP (not the US AMA list) — we tell you that up front so you can decide.
- Fits arms up to 48 cm — best here for large arms
- Large, color-lit display
- Inexpensive entry to connected tracking
Not for: STRIDE-validated but not AMA-listed — noted plainly. Doctors who insist on a VDL device should pick an Omron or A&D.
Best value Greater Goods Bluetooth Monitor
The value surprise, and a repeated Wirecutter pick: a big, high-contrast backlit display and app sync at a budget price, AMA-validated, from a US brand known for responsive support.
- Big, easy-to-read backlit numbers
- Costs like a basic unit but syncs to a phone
- AMA-validated at a budget price
Not for: Smaller support ecosystem than Omron, and the app is basic.
Best overall Omron 10 Series
The all-rounder to beat: it takes three readings and averages them automatically (how a clinic does it), stores two users, and carries both the AMA and STRIDE validation listings. Reviewers find little to fault.
- Auto-averages 3 readings for a steadier number
- Listed on both major validation registries
- Two users, 100 readings each, on the device
Not for: The pre-formed cuff can be fiddly to position on very small or very large arms.
