American Heart Association blood pressure cuff bladder length 80% arm circumference width 40%
The ideal cuff bladder length is at least 80% of the mid-upper arm circumference.
- Width: about 40% of arm circumference
- Length: 80% or more of arm circumference
Example: for an arm circumference of 30 cm, the bladder should be about 24 cm long and 12 cm wide.
A cuff that is too small gives a falsely high blood-pressure reading. AHA cuff-sizing guidance supports these proportions.
