Does the cuff size affect blood pressure?
Sheps, M.D. Using a blood pressure cuff that’s too large or too small can give you inaccurate blood pressure readings. Your doctor’s office should have several sizes of cuffs to ensure an accurate blood pressure reading. When you measure your blood pressure at home, it’s important to use the proper size cuff.

Does the cuff size affect blood pressure?
Sheps, M.D. Using a blood pressure cuff that’s too large or too small can give you inaccurate blood pressure readings. Your doctor’s office should have several sizes of cuffs to ensure an accurate blood pressure reading. When you measure your blood pressure at home, it’s important to use the proper size cuff.
What happens if the blood pressure cuff is not the right size?
A cuff that is too snug or too loose on the mid-upper arm can lead to greatly exaggerated blood pressure measurements, results of a community-based study show.
What are the effects of using a blood pressure cuff that is one size larger than appropriate?
Systolic and diastolic blood pressure were underestimated by 3-5 mm Hg in men and 1-3 mm Hg in women when the cuff was one size larger than appropriate. Systolic and diastolic blood pressure were overestimated by 2-6 mm Hg in men and 3-4 mm Hg in women when the cuff was one size smaller than appropriate.
How do you determine if a blood pressure cuff is the right size for a patient?
Select a Cuff Size Based on Arm Circumference The ideal cuff bladder length is ≥ 80 percent of the patient’s arm circumference. The ideal cuff bladder width is ≥ 40 percent of the patient’s arm circumference.
Can a tight blood pressure cuff cause high blood pressure?
If the cuff you’re using doesn’t fit properly, it could squeeze your arm too tightly, causing your skin to fold over and pinch. Not only that, but an improper cuff fit could also lead to error codes on your blood pressure monitor or incorrect — often abnormally high — blood pressure readings.
Can a BP cuff be wrong?
If a cuff is too small or too large, errors in measurement can occur. Adding to inaccuracy is automated device variability, which can account for average error in systolic BP of between -4 mm Hg and -17 mm Hg.
Do large arms affect blood pressure readings?
For every 5 cm increase in arm circumference, starting at 35 cm, a 2-5 mmHg increase in systolic blood pressure, and a 1-3 mmHg increase in diastolic blood pressure was observed. The prevalence of arms with a large circumference in the family medicine unit and hypertension clinic was 42% and 41.8%, respectively.
How do you know if a blood pressure cuff is too small?
If the blood pressure cuff does not fit correctly, the results may not be accurate. This cuff is too small. The inflatable part of the cuff needs to be at least as long as the widest measurement around your upper arm.
What is the biggest blood pressure cuff size?
Recommended Cuff Sizes for Accurate Measurement of Blood Pressure
| Patient | Recommended cuff size |
|---|---|
| 27 to 34 cm | 16 × 30 cm (adult) |
| 35 to 44 cm | 16 × 36 cm (large adult) |
| 45 to 52 cm | 16 × 42 cm (adult thigh) |
| Children (by age)* |
Are blood pressure cuff sizes underestimated?
Systolic and diastolic blood pressure were underestimated by 3-5 mm Hg in men and 1-3 mm Hg in women when the cuff was one size larger than appropriate. Systolic and diastolic blood pressure were overestimated by 2-6 mm Hg in men and 3-4 mm Hg in women when the cuff was one size smaller than appropriate.
How far should a blood pressure cuff be inflatable?
The inflatable part of the blood pressure cuff should cover about 40% of the distance around (circumference of) your upper arm. The cuff should cover 80% of the area from your elbow to your shoulder.
What should I do if my blood pressure cuff is too small?
If you’re concerned about the size of your cuff or your blood pressure readings, talk to your doctor. You may need to have your blood pressure taken several times during your visit using the same, properly sized cuff in the same arm. An average of these blood pressure readings should give your “true” blood pressure for that visit.
Why is it important to have a good blood pressure cuff?
Having a properly fitting cuff is important because poorly fitting cuffs won’t give accurate blood pressure measurements. If you’re concerned about the size of your cuff or your blood pressure readings, talk to your doctor.
