Grip Strength: Males, Age 13

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 these numbers mean for males aged 13

A score around 25 kg is typical (50th percentile) for males in this age group. Scores above about 29.8 kg fall near the 75th percentile or higher, indicating above-average performance. Scores below about 20.5 kg fall near the 25th percentile, about 75% of the reference population scored higher.

Percentiles show how common a value is, not whether it is healthy.
