You can find your heart rate in about 15 seconds using nothing but two fingers and a clock. Place your index and middle fingers on the inside of your wrist or the side of your neck, count the beats you feel, and multiply to get your beats per minute. A normal resting heart rate for adults falls between 60 and 100 beats per minute (bpm).
The Wrist Method (Radial Pulse)
The easiest place to check your pulse is the inside of your wrist, on the thumb side. Turn one hand palm-up and place the pads of your index and middle fingers on the groove just below the base of your thumb. You should feel a gentle thumping under your fingertips. Press lightly. Too much pressure can actually compress the artery and make the pulse harder to detect.
Don’t use your thumb to check your pulse. Your thumb has its own pulse, and it can mix with what you’re trying to measure.
The Neck Method (Carotid Pulse)
If you can’t feel a pulse at your wrist, the side of your neck is a reliable backup. Place two or three fingerpads in the soft groove between your windpipe and the large muscle running down the side of your neck, roughly in the middle third of the neck. You’ll typically feel a stronger beat here than at the wrist.
Two important rules with the neck method. First, only check one side at a time. Pressing on both carotid arteries simultaneously reduces blood flow to the brain. Second, stay in the middle third of the neck. Pressing too high can stimulate a pressure-sensitive area called the carotid sinus, which may cause your heart rate to drop or make you feel lightheaded.
Counting and Calculating Your BPM
Once you feel a steady beat, look at a clock or timer. Count the number of beats in 15 seconds, then multiply by four. That’s your heart rate in beats per minute. If you want more accuracy, count for 30 seconds and multiply by two. A full 60-second count is the most precise, especially if your rhythm feels uneven or irregular.
For example, if you count 18 beats in 15 seconds, your heart rate is 72 bpm. If you count 34 beats in 30 seconds, that’s 68 bpm.
Getting an Accurate Resting Reading
Your resting heart rate is the number that matters most for tracking your baseline health, but you need to measure it under the right conditions. The best time is first thing in the morning, before you get out of bed. Your body is as close to a true resting state as it gets: no caffeine, no movement, no stress response from the day.
If morning isn’t practical, sit or lie down quietly for at least 10 minutes before measuring. Avoid checking right after exercise, a meal, or a stressful moment. All of these temporarily raise your heart rate and give you a number that doesn’t reflect your baseline.
Using a Smartwatch or Fitness Tracker
Most wearable devices use small LED lights pressed against your skin to detect blood flow changes in your wrist. Each pulse of blood causes a tiny shift in light absorption, and the sensor translates that into a heart rate reading. This is fundamentally different from a chest strap monitor, which detects the heart’s electrical signals directly.
For a simple heart rate number, wrist-based sensors are generally reliable. A study of 31 healthy adults found excellent agreement between wrist sensors and chest-based monitors when people were lying down, with correlation scores above 0.95 out of 1.0. Accuracy dropped slightly in a seated position, and the wrist sensors tended to overestimate certain readings when people were upright. If your wearable gives you a number that seems off, a quick manual pulse check is a good way to verify it.
Chest strap monitors remain the more accurate option for tracking heart rate during intense exercise, when arm movement and sweat can interfere with optical wrist sensors.
Normal Resting Heart Rate by Age
The 60 to 100 bpm range applies to adults and adolescents from about age 13 onward. Children have faster resting heart rates because their hearts are smaller and need to beat more often to circulate the same volume of blood.
- Newborns (birth to 4 weeks): 100 to 205 bpm
- Infants (4 weeks to 1 year): 100 to 180 bpm
- Toddlers (1 to 3 years): 98 to 140 bpm
- Preschool age (3 to 5 years): 80 to 120 bpm
- School age (5 to 12 years): 75 to 118 bpm
- Adolescents and adults (13+): 60 to 100 bpm
Athletes and very fit individuals often have resting heart rates in the 40s or 50s. A well-conditioned heart pumps more blood per beat, so it doesn’t need to beat as frequently to do the same job. A resting rate below 60 in someone who exercises regularly is normal and generally a sign of cardiovascular fitness, not a problem.
When a Heart Rate Is Too High or Too Low
A resting heart rate consistently above 100 bpm is called tachycardia. A resting rate below 60 bpm is called bradycardia. Neither number is automatically dangerous. Context matters: a trained runner with a rate of 48 is fine, while a sedentary person with the same number and symptoms of fatigue is a different situation.
The symptoms to pay attention to are dizziness, lightheadedness, fainting or near-fainting, unusual fatigue during physical activity, shortness of breath, confusion, and chest pain. These suggest your heart rate, whether too fast or too slow, is preventing enough oxygen from reaching your brain and organs. Fainting, difficulty breathing, or chest pain lasting more than a few minutes warrants a call to emergency services.
Estimating Your Maximum Heart Rate
Your maximum heart rate is the fastest your heart can beat during all-out exertion. The classic formula is 220 minus your age. A 35-year-old would get 185 bpm. A newer formula, published in 2001, uses 208 minus 0.7 times your age, which gives a 35-year-old a max of about 184 bpm.
At age 40, both formulas produce the same result. Below 40, the old formula overestimates your max. Above 40, it underestimates it. Neither formula is perfect for any individual, since genetics, fitness level, and medications all shift the real number. But either one gives you a reasonable ballpark for setting exercise intensity zones. Most moderate exercise targets 50 to 70 percent of your estimated max, while vigorous exercise falls in the 70 to 85 percent range.
