Grip Strength Percentile.
Grip strength is one of the cleanest single predictors of all-cause mortality — beating blood pressure in some cohorts. Enter your dynamometer reading to see your age- and sex-adjusted percentile.
Average Grip Strength by Age
Grip strength peaks in the 30s and declines with age, and men average notably higher than women. The table below shows typical peak force (dominant hand, kg) for each age band — the average and the usual range (mean ± 1 SD, covering roughly the middle two-thirds of people).
| Age | Men — avg (range) | Women — avg (range) |
|---|---|---|
| 18–29 | 47 kg (38–56) | 29 kg (23–35) |
| 30–39 | 47 kg (38–56) | 29 kg (23–35) |
| 40–49 | 45 kg (36–54) | 28 kg (22–34) |
| 50–59 | 41 kg (32–50) | 25 kg (19–31) |
| 60–69 | 36 kg (28–44) | 22 kg (17–27) |
| 70+ | 30 kg (22–38) | 18 kg (13–23) |
Peak isometric grip, dominant hand, kg. Norms adapted from Dodds et al. (PLoS ONE 2014) and NHANES. EWGSOP2 (2019) flags weakness below 27 kg for men and 16 kg for women.
Frequently Asked Questions
What is the average grip strength?+
Average grip strength depends heavily on age and sex. Broadly, healthy adult men average roughly 40–50 kg of peak force per hand and women roughly 25–30 kg, peaking in the 30s and declining gradually after. Enter your dynamometer reading above to see your exact percentile rather than a single average.
What are normal grip strength values by age?+
Normal values fall along a curve: they rise into the early 30s, plateau, then decline — more steeply after 60. This calculator compares your reading against age- and sex-specific normative data (Dodds 2014, NHANES), so "normal" is judged against people of your own age and sex, not a global figure.
What is the average human hand strength?+
Measured as maximal isometric grip on a hand dynamometer, average human hand strength is around 40–50 kg for adult men and 25–30 kg for adult women, with the dominant hand usually a little stronger. Values below the EWGSOP2 weakness cut-points (about 27 kg for men, 16 kg for women) flag low strength worth addressing.
Why does grip strength predict mortality?+
Grip strength is a cheap proxy for total-body muscle strength and neuromuscular health, both of which decline with frailty. Large cohort studies (e.g. PURE) found each ~5 kg drop in grip strength was associated with a measurable rise in all-cause and cardiovascular mortality — which is why it is used as a vital sign of healthy aging.
Why a hand-squeeze predicts mortality.
Grip strength is a remarkably honest proxy for total-body muscle strength and quality, and muscle is the organ of longevity — it disposes of glucose, protects against falls, and tracks the loss of function that ends independence. Because it is cheap, fast, and reproducible, epidemiologists have measured it in hundreds of thousands of people.
Leong et al. (Lancet 2015, ~140,000 adults across 17 countries) found each 5 kg drop in grip strength was associated with a 16% higher all-cause mortality risk — a stronger signal than systolic blood pressure. The good news is that grip and the posterior chain respond fast to heavy carries, rows, deadlifts, and dead hangs, so percentile is a number you can deliberately climb.
