How it works
- The average grip strength figures shown here are representative benchmarks based on the age- and sex-specific grip strength (average of left and right) from Japan's Sports Agency "Survey on Physical Fitness and Athletic Ability (New Physical Fitness Test)." The figures vary by year and survey round, so refer to the official statistics for the latest and most accurate values.
- In the New Physical Fitness Test, grip strength is measured twice on each side, and the record is the average of the highest value on the left and right (kg, to one decimal place). When measuring at home, entering the average of the highest value on each side allows a more accurate comparison.
- The rating is based on the ratio (your value / average): 1.2x or more is "Well above average," 1.05x or more is "Above average," 0.95-1.05x is "About average," 0.8-0.95x is "Slightly below average," and under 0.8x is "Below average."
- Boys' average grip strength rises from about 9.0 kg at age 6 and reaches around 43-44 kg at ages 17-19. Girls' rises from about 8.5 kg at age 6 and levels off at around 26-27 kg at ages 15-19.
- Grip strength is also attracting attention as an indicator of whole-body muscular strength and overall health. These figures are only rough guides, and individual differences in condition and physique are large, so please use the results as a reference without worrying about them too much.
