You can check your heartbeat in under a minute using just two fingers and a clock. The most reliable spot is the inside of your wrist, though your neck works well too. For most adults, a normal resting heart rate falls between 60 and 100 beats per minute.
Finding Your Pulse at the Wrist
The wrist (radial pulse) is the easiest and most comfortable place to check. Turn one hand so your palm faces up. Find the spot between your wrist bone and the tendon on your thumb side. Place the tips of your index and middle fingers from your other hand on that spot and press gently until you feel a steady throb.
Don’t use your thumb. It has its own pulse, which can mix with the signal you’re trying to read and throw off your count.
Finding Your Pulse at the Neck
If you’re having trouble feeling anything at the wrist, try your neck. Place the tips of your index and middle fingers in the groove next to your windpipe, on one side. You’ll feel the carotid artery pulsing just beneath the skin. Press lightly. Too much pressure can actually slow your heart rate slightly and give you an inaccurate reading.
Counting the Beats
Once you’ve found a clear pulse, watch a clock or set a timer. You have two options: count beats for a full 60 seconds to get your heart rate directly, or count for 15 seconds and multiply by four. The 60-second method is more accurate, especially if your rhythm feels uneven. The 15-second shortcut works fine for a quick check when your pulse seems steady and regular.
Your first beat counts as zero, not one. Start your count on the next beat after you begin timing.
Getting an Accurate Resting Reading
Your resting heart rate is the baseline number that matters most for tracking your health over time, and several things can throw it off. Caffeine, stress, and recent movement all push the number higher. For the most reliable measurement, check your pulse first thing in the morning before you get out of bed, or after sitting quietly for at least five minutes. Avoid coffee or exercise beforehand.
Body position matters too. Your heart rate is slightly higher when standing than when sitting or lying down, so try to measure in the same position each time if you’re comparing day to day.
Normal Heart Rate by Age
Heart rate varies significantly with age. Babies and young children have much faster resting rates than adults because their hearts are smaller and need to pump more frequently.
- 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
- Preschoolers (3 to 5 years): 80 to 120 bpm
- School age (5 to 12 years): 75 to 118 bpm
- Teens 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. This is normal and generally a sign of cardiovascular fitness, not a problem.
What Your Rhythm Tells You
Beyond speed, pay attention to the pattern. A healthy pulse feels like a steady, even drumbeat. If you notice skipped beats, extra beats, or a rhythm that feels completely chaotic, like a bag of popcorn popping at random intervals, that could signal an irregular heart rhythm.
Manual pulse checking is actually quite good at catching atrial fibrillation, the most common type of dangerous irregular rhythm. Studies in older adults show that feeling for an irregular pulse detects atrial fibrillation about 94% of the time. The catch is that about 28% of people flagged as irregular turn out to be fine on further testing, so an irregular pulse is a reason to get checked, not a diagnosis on its own. An ECG (the test with sticky patches on your chest) is needed to confirm what’s actually going on.
One important limitation: a manual check is a snapshot of a single moment. Some irregular rhythms come and go. If your heart rhythm is only abnormal occasionally, a quick pulse check might miss it entirely.
When the Numbers Run High or Low
A resting heart rate consistently above 100 bpm in an adult is considered tachycardia. Below 60 bpm is bradycardia. Neither number is automatically dangerous. Plenty of healthy, fit people sit below 60 with no symptoms at all. And a rate above 100 can happen from anxiety, dehydration, fever, or too much caffeine.
What matters more than a single reading is the combination of your heart rate and how you feel. A rate of 110 while you’re sitting calmly and feeling dizzy or short of breath is more concerning than the same number right after climbing stairs. Persistent readings outside the normal range, especially paired with lightheadedness, chest discomfort, or fainting, are worth bringing up with a doctor.
How Wearables and Phone Apps Compare
Smartwatches and fitness trackers use tiny LED lights that shine through your skin and measure changes in blood flow. At rest and during moderate activity, these sensors are quite accurate. Validation studies show optical heart rate sensors can match medical-grade ECG readings with an average error of less than 1 bpm at rest. During intense exercise, the margin of error widens, sometimes reaching 5 to 10 bpm or more depending on the device and how it fits.
Smartphone apps work on a similar principle. You place your fingertip over the rear camera, and the app detects tiny color changes in your skin as blood pulses through. These typically land within 1 to 3 bpm of a medical device under good conditions. However, accuracy drops with darker skin tones (because more light is absorbed by melanin, weakening the signal), poor lighting, or movement. These apps are fine for casual tracking but aren’t validated for medical use.
For day-to-day fitness tracking, wearables are convenient and reliable enough. For a specific concern about your heart rate or rhythm, a manual check gives you both the rate and a feel for regularity that no wrist gadget can fully replicate.
