Grip Strength Norm Calculator
The revised European consensus on sarcopenia (EWGSOP2, 2019) puts the line for low muscle strength at 27 kg for men and 16 kg for women. The Asian working group (AWGS 2019) sets it slightly higher, at 28 kg and 18 kg. A 70 kg man squeezing 38 kg sits 11 kg above the line, or 0.54 per kilogram of body weight. This measures something different from the muscle tools already in the section: ffmi and muscle-mass-index describe how much muscle there **is**, and one-rep-max describes a weight moved in one specific lift. Grip is the only measure of **force** here that carries published cut-offs, which is why its links to walking speed, surgical recovery and mortality keep turning up in the literature.

What it means
A grip of 38 kg is 11 kg above the EWGSOP2 cut-off of 27 kg, so this screen does not flag low strength.
Formula
Result = Grip strength (kg) < cutoff(Sex (M1 / F0)) → 1 : 0 — cutoff = 27 / 16
The make of dynamometer and your posture shift the number by several kilograms. Sit with the elbow at ninety degrees, squeeze three times with the stronger hand, and take the best attempt. Pain or arthritis in the wrist or fingers drags the reading down regardless of muscle. This line exists to sort people for a closer look and decides nothing on its own — an assessment that also weighs muscle mass and physical function is what governs.

Frequently asked questions
Q. How is Grip Strength Norm Calculator calculated?
Result = Grip strength (kg) < cutoff(Sex (M1 / F0)) → 1 : 0 — cutoff = 27 / 16 — The revised European consensus on sarcopenia (EWGSOP2, 2019) puts the line for low muscle strength at 27 kg for men and 16 kg for women. The Asian working group (AWGS 2019) sets it slightly higher, at 28 kg and 18 kg. A 70 kg man squeezing 38 kg sits 11 kg above the line, or 0.54 per kilogram of body weight. This measures something different from the muscle tools already in the section: ffmi and muscle-mass-index describe how much muscle there **is**, and one-rep-max describes a weight moved in one specific lift. Grip is the only measure of **force** here that carries published cut-offs, which is why its links to walking speed, surgical recovery and mortality keep turning up in the literature.
Q. Can you walk through an example?
With Grip strength (kg) 38kg, Sex (M1 / F0) 1, Weight (kg) 70kg, the answer is Result 0.
Q. What do I need to enter?
Enter Grip strength (kg), Sex (M1 / F0), Weight (kg). The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Grip strength (kg) (kg) moves the answer to Grip strength (kg) (kg) 19 → Result 1 and Grip strength (kg) (kg) 76 → Result 0. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
The make of dynamometer and your posture shift the number by several kilograms. Sit with the elbow at ninety degrees, squeeze three times with the stronger hand, and take the best attempt. Pain or arthritis in the wrist or fingers drags the reading down regardless of muscle. This line exists to sort people for a closer look and decides nothing on its own — an assessment that also weighs muscle mass and physical function is what governs.
