How to Check Your Blood Pressure Correctly at Home

Step-by-step tips for an accurate home blood pressure reading, including the right cuff, how to sit, when to measure, and how to keep a log.

Checking your blood pressure at home can help you and your care team see how you are doing between visits. A few simple habits help make your readings more reliable. First, talk with your health care team about how often and when to measure.

Choose the right monitor and cuff

  • The American Heart Association (AHA) recommends an automatic monitor with a cuff that goes around your upper arm. Wrist and finger monitors give less reliable readings.
  • Pick a monitor that has been validated, which means it was tested for accuracy. If you are an older adult, check that it was validated for people your age.
  • Make sure the cuff fits. Measure around your upper arm and choose a monitor that comes with the right cuff size.
  • Do not rely on cuffless devices, such as smartwatches, for blood pressure. The 2025 high blood pressure guideline advises against it.

Get ready

In the 30 minutes before you measure:

  • Do not eat or drink.
  • Do not have caffeine or alcohol, smoke, or exercise.

Right before you measure:

  • Empty your bladder.
  • Remove clothing from the arm you will use. The cuff goes on bare skin, not over a sleeve. You can use either arm.

Sit the right way

  • Sit in a comfortable chair with your back supported.
  • Keep both feet flat on the floor, with legs uncrossed.
  • Rest your arm on a table so the cuff is about level with your heart. A pillow under your arm can help.
  • Place the bottom of the cuff just above the bend of your elbow. It should be snug but not too tight.
  • Rest quietly for at least 5 minutes before you start. Do not talk or use the phone, and stay quiet while the monitor works.

Measure at the same time each day

  • Take your readings at the same time each day.
  • Each time, take two readings about one minute apart.

Keep a log

  • Write down each reading, both numbers, with the date and time.
  • If your monitor saves readings in its memory, bring it to your medical appointments.

Have your monitor checked

Bring your monitor to your doctor's office. Your health care professional can watch how you take a reading and compare your monitor's numbers with the office equipment. The AHA suggests bringing it in once a year, or as often as the maker directs, to make sure it stays accurate.

If you are in Willow Harbor at Home, your monitor sends each reading by itself through a built-in cellular connection, so no Wi-Fi or smartphone is needed. Your care team reviews the readings and calls each month to check in.
