Grip Strength

Grip strength measures the force produced when squeezing a hand dynamometer. It is a reliable marker of overall muscular strength and has been linked to functional independence, mobility, and mortality risk in research. Adult norms (ages 20-80+) are from the iGRIPS international norms (n≈2.4M adults worldwide). Youth norms (ages 9-17) are from the Tomkinson 2018 Eurofit meta-analysis (n=203,295 across 24 European countries). Because these come from different studies and populations, the trend chart shows both as a single continuous line, note that the gap between ages 17 and 20 represents a source boundary, not a true biological break.

What to expect by age group

Among adults in their 30s, the middle 50% score 44 to 56 kg for men and 27 to 36 kg for women. Grip strength peaks around age 30 to 39 in both sexes, then declines gradually through midlife and more steeply in older age; men average roughly 19 kg more than women throughout adulthood. Scores below 44 kg (men) or 27 kg (women) are typically below average for this age group; scores above 56 kg (men) or 36 kg (women) are above average.

Frequently Asked Questions

What is a good grip strength for my age?

Grip strength varies by age and sex. Use the percentile table above to compare your score. The 50th percentile represents the median for your demographic. A score at P75 or above is considered above average, while P25 or below is below average.

Why does grip strength matter?

Research has linked grip strength to overall muscular strength, functional independence, and health outcomes in aging populations. It is used as a clinical screening tool for sarcopenia (muscle loss) and frailty in older adults.

How is grip strength measured?

Grip strength is measured using a hand dynamometer. You squeeze the device as hard as possible, and the result is recorded in kilograms. Most protocols use the dominant hand, and the best of two or three trials is recorded.

Why do norms for ages 9-17 come from a different source?

Youth norms use the Tomkinson 2018 Eurofit meta-analysis (n=203,295), which pooled data from 24 European countries using the Eurofit handgrip protocol. Adult norms use the iGRIPS international meta-analysis (n≈2.4M). These are different populations tested under slightly different conditions, so they should not be directly compared. The trend chart shows both series with a visible gap at the source boundary (ages 17 to 20).

Why are P25 and P75 approximate for youth norms?

The Tomkinson 2018 study reports percentiles at P20, P30, P70, and P80, but not P25 or P75. We interpolate: P25 = (P20 + P30) / 2 and P75 = (P70 + P80) / 2. These are estimates, not source-reported values.
