Grip Strength by Age Calculator
Compare a handgrip reading in kilograms to age- and sex-typical norms and the sarcopenia weakness cutoff.
How it works
percent of norm = grip ÷ age/sex-typical mean × 100 · low grip flagged below EWGSOP2 cutoffs (< 27 kg men, < 16 kg women)
Handgrip strength, measured with a dynamometer, is a strong marker of overall muscle strength and a predictor of mobility, recovery and mortality in older adults. Strength peaks in early adulthood and declines gradually after the 50s, so a reading is best judged against age- and sex-typical values. The European sarcopenia group (EWGSOP2) uses fixed weakness cutoffs of 27 kg for men and 16 kg for women; falling below them is one criterion — not a diagnosis — that prompts a fuller muscle assessment.
Worked example
A 65-year-old man with a best grip of 32 kg is compared to an age-typical average of about 38 kg, giving roughly 84% of the norm. Because 32 kg is above the 27 kg weakness cutoff, he is not flagged for low grip strength.
Frequently asked questions
How should grip strength be measured?
With a calibrated handgrip dynamometer, seated with the elbow at 90 degrees, taking the best of two or three squeezes on the dominant hand. Home spring grippers are not accurate enough for these cutoffs.
Why does grip strength matter beyond the hand?
It correlates with whole-body strength and is easy to measure, so it is used as a proxy for muscle health. Low grip strength is linked to higher risk of falls, disability and poorer surgical recovery.
Can I improve my grip strength?
Yes. Whole-body resistance training, adequate protein and treating any underlying illness all help. Grip typically rises alongside general strength rather than from grip-only exercises.
