Compare your hand dynamometer reading to published norms for your age and sex, and see what it means for your health.

Grip strength is one of the simplest, cheapest measurements you can take, and it turns out to be one of the more revealing ones. A quick squeeze on a hand dynamometer says more about your overall health than most people realize.
Grip strength correlates closely with total-body muscle mass, functional independence, and, in large population studies, long-term health outcomes. It is widely used in clinical settings to screen for sarcopenia, the age-related loss of muscle mass, and to track recovery after surgery or illness.
Grip strength typically peaks in the late 20s to mid-30s, then gradually declines by roughly 1-2% per year after 40, with the decline accelerating after 65. Men generally test stronger than women at every age, largely due to differences in muscle mass and hand size, which is why norms are broken out by sex.
A single below-average reading is not a diagnosis, results vary with technique, time of day, and equipment. That said, a consistently low grip strength relative to your age and sex group is worth mentioning to a doctor, particularly in older adults, since it has been associated in research with reduced functional independence and increased fall risk.
Grip strength is one piece of a bigger picture, check your BMI Calculator and Body Fat % Calculator for a fuller view of your body composition, and if you are training to improve your numbers, our Calorie & TDEE Calculator in Nutrition can help make sure you are fueling muscle growth properly.
It depends heavily on age and sex, a healthy adult male in his late 20s to 30s often squeezes 45-55 kg on his dominant hand, while a woman of the same age typically averages 27-34 kg. Use the calculator above for a comparison specific to your group.
Yes, research shows consistent training, dead hangs, farmer carries, dedicated grip tools, and compound pulling exercises, can meaningfully improve scores within 6-12 weeks.
A hand dynamometer gives the most consistent, comparable reading, since it standardizes the measurement. Without one, you can only estimate roughly by feel, which is not reliable enough to compare against norms.
Large population studies, including the PURE study published in The Lancet, have found grip strength predicts cardiovascular risk and all-cause mortality, often about as well as blood pressure, likely because it serves as a simple proxy for overall muscle mass and physical function.
