To count your BPM (beats per minute), place two fingers on your wrist or neck, count the beats you feel over a set time period, and multiply to get your per-minute rate. A normal resting heart rate for adults falls between 60 and 100 BPM, so that’s the range you’re likely checking against.
Finding Your Pulse
You have two reliable spots to feel your pulse: your wrist and your neck. The wrist is the easier and safer option for most people.
For the wrist (radial pulse): Turn one hand palm-up. Place the tips of your index and middle fingers on the inside of the opposite wrist, just below the base of your thumb. You’re feeling for the artery that runs alongside the prominent tendon in the center of your wrist. Shift your fingers slightly toward the thumb side until you feel a steady tapping.
For the neck (carotid pulse): Place the tips of your index and middle fingers in the groove next to your windpipe, on either side of your neck. Press lightly. This pulse is stronger and easier to find, which makes it useful during exercise when your wrist pulse can be harder to detect. One important caution: don’t press too hard on the neck artery, as this can restrict blood flow. If you’ve ever been told you have plaque buildup in your neck arteries, skip this location entirely and use your wrist.
Never use your thumb to check your pulse. Your thumb has its own pulse, and it will mix with the signal you’re trying to count.
How Long to Count
The simplest method is counting beats for 15 seconds, then multiplying by four. This gives you a quick BPM estimate that’s good enough for everyday use. But shorter counting windows introduce more error, because any miscount gets multiplied along with the real beats.
A study published in Ergonomics measured exactly how much accuracy you lose at different counting durations. Counting for just 10 seconds produced an average error of about 2.5 BPM, with a 10% chance of being off by 5 or more beats. Counting for 15 seconds cut the average error to about 1.9 BPM. Counting for 30 seconds brought it down further to roughly 1 BPM, with errors rarely exceeding 3 or 4 beats. A full 60-second count is the most accurate but least practical.
For a quick check during exercise, 15 seconds is fine. If you’re tracking your resting heart rate over time or noticing something feels off, count for a full 30 seconds and multiply by two. The extra 15 seconds nearly cuts your margin of error in half.
Step-by-Step Count
Here’s the process from start to finish:
- Get a timer ready. Use your phone’s stopwatch or a clock with a second hand.
- Find your pulse at the wrist or neck using two fingers.
- Start counting on a beat. When you feel a beat, start your timer and count that beat as “one.”
- Count every beat for your chosen duration (15 or 30 seconds).
- Multiply. If you counted for 15 seconds, multiply by 4. If you counted for 30 seconds, multiply by 2. That number is your BPM.
For example, if you count 18 beats in 15 seconds, your heart rate is 72 BPM. If you count 34 beats in 30 seconds, it’s 68 BPM.
Getting an Accurate Resting Heart Rate
Your resting heart rate is the baseline number that matters most for tracking your heart health over time. To get a true reading, you need to measure it when your body is genuinely at rest. The best time is right after you wake up in the morning, before you get out of bed or reach for coffee. You should be awake, calm, and not moving.
Several things can temporarily raise your heart rate and throw off a resting measurement. Caffeine, nicotine, alcohol, stress, and even a hot room will push the number up. Physical activity elevates your heart rate for a while after you stop, so sitting down for five minutes after climbing stairs isn’t quite enough to get a true resting value. If you want to track trends, measure at the same time each day for several days and look at the average.
Normal Ranges by Age
The 60 to 100 BPM range applies to adults and adolescents age 13 and older. Children run faster. Here’s what’s typical at rest:
- 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 people who exercise regularly often have resting rates in the 40s or 50s. A well-trained heart pumps more blood per beat, so it doesn’t need to beat as often to keep up.
Using BPM During Exercise
If you’re counting your heart rate to gauge workout intensity, you first need to estimate your maximum heart rate. The standard formula is 220 minus your age. So a 35-year-old has an estimated maximum of 185 BPM.
From there, you can aim for specific zones. Moderate-intensity exercise (brisk walking, easy cycling) puts you at 64% to 76% of your max. For that 35-year-old, that’s roughly 118 to 141 BPM. Vigorous exercise (running, high-intensity intervals) falls between 77% and 93% of your max, or about 142 to 172 BPM for the same person.
During a workout, pause briefly, find your pulse at the neck (it’s easier to locate when you’re breathing hard), and count for 15 seconds. Multiply by four. Your heart rate drops quickly once you stop moving, so start counting within a second or two of stopping.
Smartwatches vs. Manual Counting
Wrist-worn heart rate monitors use light sensors to detect blood flow under your skin, giving you a continuous BPM reading without any counting at all. In testing against medical-grade equipment, the Apple Watch and Mio Fuse were accurate about 91% of the time across resting and various treadmill speeds. The Fitbit Charge HR and Basis Peak were accurate about 83% to 84% of the time.
These devices are convenient for tracking trends and monitoring exercise zones in real time. But they can struggle with dark tattoos on the wrist, loose bands, and very high-intensity movements. For a one-time check of your resting heart rate, a careful 30-second manual count is just as reliable as any consumer wearable.
What an Irregular Pulse Feels Like
When you’re counting, pay attention to the rhythm, not just the speed. A healthy pulse beats steadily, like a metronome. If you feel the beat skipping, adding extra taps, or spacing unevenly, that’s an irregular rhythm. Some people describe it as a flutter or a sensation that the heart “stumbles” before catching up.
An occasional skipped beat is common and usually harmless. But if the irregularity is persistent, or if you notice it alongside dizziness, chest pain, unusual fatigue, shortness of breath, or fainting, those are signs worth getting evaluated. A resting heart rate consistently below 60 BPM (in someone who isn’t an athlete) or consistently above 100 BPM also warrants a conversation with a doctor. When you count manually, you get something a smartwatch can’t easily show you: the feel of your heart’s rhythm, beat by beat.
