How it works
Find out how your grip strength compares to others your age and sex. Enter your grip strength measurement in kg and get your percentile ranking based on NHANES population data. Grip strength is increasingly recognized as a key biomarker for overall health and longevity.
How to Use This Calculator
- Measure grip strength with a hand dynamometer, taking three readings per hand.
- Record the best reading from your dominant hand.
- Enter your age, sex, and the grip strength value in kilograms or pounds.
- Review your percentile compared to NHANES population data.
- Track changes every 4-8 weeks to detect early declines.
Example
Inputs: 50-year-old male with dominant hand grip strength of 48 kg.
Result: 75th percentile for age and sex.
What it means: Grip strength above the 50th percentile correlates with lower mortality risk, better cognitive aging, and faster recovery from illness.
Tips
- Take three readings with a 30-second rest between each and use the best one. First attempts are usually lower due to neural warmup.
- Keep the elbow at 90 degrees, arm unsupported, and squeeze for 3-5 seconds at full effort for a valid reading.
- Grip strength typically peaks in your 30s and declines 1% per year after age 50. Strength training slows the decline substantially.
- Deadlifts, farmers walks, and dead hangs are the most effective exercises for building grip strength and forearm mass.
- A sudden drop of 5+ kg without explanation is worth investigating. It can signal underlying health issues beyond aging.

Frequently Asked Questions
- Why does grip strength matter for health?
- Research has shown that grip strength is one of the strongest predictors of overall mortality and cardiovascular health. A large meta-analysis published in The BMJ found that each 5 kg decrease in grip strength was associated with a 17% increased risk of cardiovascular death. It serves as a practical proxy for total-body muscular strength and functional capacity.
- What is a good grip strength for my age?
- Average grip strength for men ranges from about 45 to 55 kg in their 20s and 30s, declining gradually to around 35 to 45 kg by age 60. For women, averages range from about 25 to 35 kg in their 20s and 30s, declining to around 20 to 28 kg by age 60. This calculator shows your percentile ranking relative to population norms for your age and sex.
- How can I improve my grip strength?
- Dead hangs, farmer carries, and dedicated grip trainers are among the most effective exercises for building grip strength. Training grip 2 to 3 times per week with progressive overload will produce noticeable improvements within a few weeks. Heavy compound lifts like deadlifts and rows also develop grip strength as a secondary benefit.
