Normal Heart Rate by Age: The Complete Chart
Normal Heart Rate by Age — Complete Chart
The following ranges are based on the American Heart Association (AHA) guidelines and population data from the Health eHeart Study (92,457 participants).
| Age Group | Normal Range (bpm) | Average | Status |
|---|---|---|---|
| Newborn (0–1 month) | 100–160 | 140 | Normal |
| Infant (1–11 months) | 80–160 | 120 | Normal |
| Toddler (1–2 years) | 80–130 | 110 | Normal |
| Child (3–4 years) | 80–120 | 100 | Normal |
| Child (5–6 years) | 75–115 | 95 | Normal |
| Child (7–9 years) | 70–110 | 90 | Normal |
| Child (10–11 years) | 60–105 | 85 | Normal |
| Adolescent (12–15 years) | 60–100 | 80 | Normal |
| Adult (18–25 years) | 60–100 | 73 | Normal |
| Adult (26–35 years) | 60–100 | 74 | Normal |
| Adult (36–45 years) | 60–100 | 75 | Normal |
| Adult (46–55 years) | 60–100 | 76 | Normal |
| Adult (56–65 years) | 60–100 | 76 | Normal |
| Older adult (65+) | 60–100 | 74 | Normal |
For anyone 18 and older, 60–100 bpm at rest is the accepted clinical normal. Below 60 is bradycardia; above 100 is tachycardia — but both can be normal depending on the individual.
Why Heart Rate Decreases with Age
Heart rate naturally slows as we move from infancy into adulthood. Several physiological changes drive this:
1. Heart size increases. A larger heart pumps more blood per beat (higher stroke volume), so it needs fewer beats per minute to maintain cardiac output.
2. Autonomic nervous system matures. In newborns, sympathetic tone (the "accelerator") dominates. Vagal tone (the "brake") strengthens with age, resulting in a lower resting rate.
3. SA node changes. The sinoatrial node — the heart's natural pacemaker — gradually slows its intrinsic firing rate over decades of life.
Normal Heart Rate by Age: Men vs. Women
On average, women have a slightly higher resting heart rate than men across all adult age groups. The difference is typically 2–7 bpm and is attributed to smaller average heart size (requiring more beats to maintain the same output) and hormonal effects on the SA node.
Note: values below are true resting HR (measured correctly at rest). Real-world ambulatory averages from wearable studies (e.g., Health eHeart Study, n=92,457) are typically 8–12 bpm higher because they capture HR throughout daily activity.
| Age | Men (resting bpm) | Women (resting bpm) |
|---|---|---|
| 18–25 | 70 | 74 |
| 26–35 | 71 | 76 |
| 36–45 | 72 | 77 |
| 46–55 | 72 | 78 |
| 56–65 | 73 | 77 |
| 65+ | 72 | 76 |
Normal Heart Rate for 50-Year-Olds
If you're in your 50s, a resting heart rate between 60 and 100 bpm is normal. The average is around 76 bpm for women and 72 bpm for men. Research from the Copenhagen City Heart Study found that a resting HR above 80 bpm at midlife was associated with a 2× increased cardiovascular risk — so while 80–99 is technically "normal," aiming for the 60–75 range is optimal.
Normal Heart Rate for 60-Year-Olds
For adults in their 60s, 60–100 bpm remains normal. Average values are 76 bpm (women) and 73 bpm (men). If you are on beta-blockers or other heart medications, your resting HR may be intentionally kept lower (50–65 bpm) — this is expected and not a concern.
Highly trained endurance athletes of any age may have resting heart rates of 40–55 bpm. This is a sign of cardiac efficiency, not illness — provided no symptoms are present.
When Is Heart Rate Too High or Too Low by Age?
For adults, the clinical thresholds are:
Bradycardia (too slow): Below 60 bpm at rest. In athletes this is normal. In non-athletes, causes include hypothyroidism, certain medications, or sick sinus syndrome.
Tachycardia (too fast): Above 100 bpm at rest, consistently. Causes range from dehydration and anxiety to anemia and thyroid disorders. See our full guide on high resting heart rate.
How to Accurately Measure Your Resting Heart Rate
For the most accurate reading:
1. Sit quietly for at least 5 minutes — no coffee, no exercise in the past 30 minutes.
2. Place two fingers on your wrist (radial pulse) or neck (carotid pulse).
3. Count beats for a full 60 seconds. (Counting for 15 seconds and multiplying by 4 is less accurate.)
4. Measure on 3 consecutive mornings and take the average.
