Grip Strength Norm Calculator

Work out grip strength norm instantly with clear inputs, formula shown and shareable results.

About Grip Strength Norm Calculator

Grip strength is a strong general marker of muscle function and even mortality risk. It peaks around age 30-35 at roughly 51 kg for men and 31 kg for women, then declines about 0.3 and 0.18 kg a year. The EWGSOP2 weakness cut-offs of 27 kg and 16 kg are used clinically to screen for sarcopenia.

Formulas

Age expectation

expected = peak - decline rate x (age - 35)

EWGSOP2 cut-offs

27 kg for men, 16 kg for women

Worked example

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • This is an estimate from population-average equations, not a medical or diagnostic assessment. Individual results vary with genetics, training history and technique. Seek advice from a qualified coach or clinician before making significant changes to training.
  • This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why does grip strength predict health outcomes?

Because it proxies total muscle mass and neuromuscular function, both of which track overall physiological reserve.

Which hand should I test?

Take the best of three squeezes on the dominant hand, or the average of both if following a clinical protocol.
