About this reference
The iGRIPS (International Grip Strength) project is a systematic review and meta-analysis that compiled handgrip strength data from approximately 2.4 million adults across 69 countries and regions. It provides international normative values by age and sex. Values were adjusted to a common reference protocol: hydraulic dynamometer, seated position, flexed elbow, neutral forearm, handle adjusted to hand size, both hands tested three times, and the maximum result retained.
Known limitations
- Aggregated from studies using different dynamometer brands and testing protocols
- Normative values represent pooled international data; country-specific norms may differ
- Most included studies used cross-sectional designs
- The published Table 2 reports P5, P10, P20, P30, P40, P50, P60, P70, P80, P90, and P95. P25 and P75 on this site are interpolated as (P20 + P30) / 2 and (P70 + P80) / 2 respectively.
