Grip Strength Standards Calculator

Q: How do I measure my grip strength at home?

You need a hand dynamometer, which can be purchased for $20-40. Stand with your arm at your side, elbow at 90 degrees, and squeeze the device as hard as you can for 3-5 seconds with your dominant hand. Take three attempts with 30-60 seconds rest between each, and use the highest reading. Some gyms and physiotherapy clinics also offer grip testing.

Q: What is a good grip strength for my age?

A "good" grip strength is at or above the median for your age decade and sex. For example, a 40-year-old male should aim for at least 43 kg (95 lbs) and a 40-year-old female for at least 27 kg (60 lbs). These medians decline naturally with age, so the benchmark adjusts accordingly.

Q: Why is grip strength linked to longevity?

Grip strength is a proxy for overall muscular strength and physiological reserve. The Leong et al. 2015 PURE study found that each 5 kg reduction in grip strength was associated with a 16% higher risk of all-cause mortality and a 17% higher risk of cardiovascular death. It reflects neuromuscular integrity, nutritional status, and the ability to perform activities of daily living.

Q: Can I improve my grip strength?

Yes. Grip strength is highly trainable at any age. Effective exercises include farmer carries, dead hangs, wrist curls, plate pinches, and using grip trainers or hand grippers. Even basic resistance training with barbells and dumbbells improves grip as a side effect. Older adults can see significant improvements within 8-12 weeks of regular training.

Q: Should I test with my dominant or non-dominant hand?

The normative data from Bohannon 2019 is reported for the dominant hand, so you should measure with your dominant hand for the most accurate comparison. If you can only measure your non-dominant hand, note that it is typically 5-10% weaker than the dominant hand.

Q: What does the longevity risk threshold mean?

The Leong et al. 2015 study identified absolute grip strength cutoffs — 26 kg for males and 16 kg for females — below which the risk of all-cause mortality increases significantly. This is an independent risk factor, meaning it adds predictive value even after accounting for age, BMI, and physical activity. Falling below this threshold does not guarantee poor outcomes, but it is a signal to discuss functional strength with your healthcare provider.

Grip strength is one of the most reliable biomarkers of overall health, functional capacity, and longevity. Research consistently shows that low grip strength predicts increased risk of cardiovascular disease, disability, and all-cause mortality — independent of muscle mass or body size. This calculator compares your measured grip strength against age- and sex-stratified normative data from Bohannon 2019 to classify your result as excellent, good, average, below average, or poor. It also flags whether your grip falls below the longevity risk threshold identified in the landmark Leong et al. Lancet 2015 study of nearly 140,000 adults across 17 countries.

Quick Answer

A healthy grip strength is at or above the age- and sex-matched median. For men aged 30-39, the median dominant-hand grip is about 45 kg (99 lbs); for women, about 28 kg (62 lbs). Grip below 26 kg (male) or 16 kg (female) is linked to increased mortality risk.

These results are estimates based on general formulas and are not a substitute for professional medical advice. Consult a healthcare provider before making health decisions.

How the Formula Works

Measure your maximum grip strength using a hand dynamometer. Squeeze as hard as you can with your dominant hand for 3-5 seconds. Record the peak reading in kg or lbs.
grip = peak dynamometer reading (dominant hand)
Look up the normative median for your age decade and sex from the Bohannon 2019 reference tables. These medians represent the 50th percentile for each group.
median = Bohannon2019(age_decade, sex)
Calculate your grip strength as a percentage of the age- and sex-matched median. This normalised score allows fair comparison across different demographics.
percent_of_median = (grip / median) x 100
Classify into a percentile band: Excellent (120%+), Good (100-119%), Average (80-99%), Below Average (60-79%), or Poor (<60%).
category = classify(percent_of_median)
Check against the longevity threshold from Leong et al. 2015: below 26 kg for males or 16 kg for females indicates increased all-cause mortality risk.
longevity_risk = grip < threshold(sex)

Methodology & Sources

Reviewed and updated April 5, 2026 · Prepared by GetHealthyCalculators Editorial Team

Normative values are drawn from Bohannon 2019, a systematic review and meta-analysis of grip strength norms stratified by age decade (20-29 through 80+) and sex. Percentile bands are expressed as a percentage of the age/sex-specific median. The longevity risk threshold (26 kg male, 16 kg female) comes from Leong et al. 2015, a prospective cohort study of 139,691 adults in the PURE study published in The Lancet, which found that each 5 kg decrease in grip strength was associated with a 16% increase in all-cause mortality.

How to Interpret Your Results

Grip strength declines naturally with age, so the calculator compares you against people of the same age decade and sex. Excellent means your grip is 20% or more above the median for your group — a strong indicator of physical robustness. Good means you meet or exceed the median. Average is slightly below the median but still within a normal functional range. Below Average suggests your grip has declined more than expected and may warrant attention through targeted training. Poor grip strength is a clinical red flag associated with higher rates of falls, disability, hospitalization, and mortality. The longevity threshold is a separate, absolute cutoff: regardless of age, falling below 26 kg (male) or 16 kg (female) carries measurably higher mortality risk.

Excellent: 120–999 — Well above the median for your age and sex. Associated with lower injury risk and better physical function.
Good: 100–119 — At or above the median. You are in a healthy range for your demographic.
Average: 80–99 — Slightly below the median but within a normal functional range.
Below Average: 60–79 — Noticeably below average. Consider incorporating grip and forearm exercises.
Poor: 0–59 — Significantly below expected range. Low grip strength is associated with higher mortality risk. Consult a healthcare provider.

Limitations

Normative data is based on population medians and may not account for individual variation in hand size, occupation, or training background.
Dynamometer calibration and testing protocol (posture, arm position, number of trials) vary between studies. Results may differ from clinical measurements.
The calculator uses dominant-hand norms. If you measured your non-dominant hand, your result may appear lower than your true dominant-hand capacity.
Age brackets are in decades. Someone at the boundary (e.g. age 29 vs. 30) may be compared to a slightly different reference group.
Longevity thresholds from Leong et al. 2015 are population-level associations and should not be interpreted as individual predictions.
Acute factors such as fatigue, injury, temperature, and time of day can significantly affect a single grip measurement.
