Blood pressure cuff size guide

A cuff that fits your arm is part of a repeatable reading. Measure around your upper arm and use this guide as a quick starting point before checking the manufacturer's instructions.

Find a starting cuff size

Measure around the middle of your bare upper arm, then compare the result with the cuff label and your monitor's instructions.

Illustrative cuff size bands
Cuff label	Arm circumference
Small adult	17–22 cm
Adult	22–32 cm
Large adult	32–42 cm
Extra-large adult	42–52 cm

These are illustrative starting bands, not universal sizes or an accessory recommendation. Manufacturer cuff ranges can span more than one band. Match your measurement to the exact compatible cuff’s printed range. If you are on a boundary, ask a pharmacist or clinician to check the fit.

Compare the result with the range printed on the exact compatible cuff. A generic size name is not a fit or compatibility check. How to measure your arm and check cuff fit.
