Blood pressure cuff sizing and compatibility
Measure around your upper arm and check the cuff’s range. When replacing a cuff, confirm its part number and the exact monitor model.
How to measure around your upper arm
Wrap a flexible tape around the midpoint between your shoulder and elbow. Measure against bare skin with your arm relaxed. The tape should fit snugly without squeezing.
Write down the measurement and compare it with the two numbers printed on the cuff. If it falls near either end, ask the manufacturer or your health care professional which range is appropriate.
Included cuffs and replacement parts for US monitors
| Model | Included range | What to check |
|---|---|---|
| OMRON Bronze BP5150 | 9–17 in (22–42 cm) | D-ring cuff. The product page lists HEM-RML31-B and optional HEM-CS24-B (7–9 in). |
| OMRON Silver BP5255 | 9–17 in (22–42 cm) | Preformed ComFit cuff. Check HEM-FL31-B in the compatibility chart. |
| OMRON EVOLV BP7000 | 22–42 cm | Integrated cuff. Check the fit of the monitor itself. |
| Beurer BM81 easyLock | 9.4–15.7 in. (24–40 cm) | Built-in easyLock cuff. Check that it fits your upper arm circumference. |
The size range tells you which arms the cuff can fit. The part number tells you which cuff the monitor accepts. Cuffs with the same size range may use different connectors.
Four details to check when replacing a cuff
- The exact monitor model on its label.
- The compatible cuff part number in the manual or accessories chart.
- The cuff range and your upper arm circumference.
- What the listing includes and the shape of the connector.
If a chart shows more than one part number, check the manual that came with your monitor. For an integrated cuff, check the fit of the monitor as a whole.
Common questions about fit and home use
Can two people share a cuff?
Check that both arm measurements fall within the cuff range. If you share a monitor, check how it keeps readings separate.
What if the cuff range does not fit?
Look for a compatible size that covers your measurement or a monitor with the right range. See how to position the cuff and how to check validation.
