Grip strength is one of the most powerful predictors of long-term health outcomes, including cardiovascular risk, all-cause mortality, and functional independence as you age. Enter your grip strength measurement and see how you compare to NHANES population norms for your age and sex — with health context and percentile ranking.

How to Use the Grip Strength Comparison Tool
Grip strength testing is simple, inexpensive, and provides remarkably useful health information. A 2015 study in The Lancet involving 140,000 people from 17 countries found that each 11 lbs (5 kg) decline in grip strength was associated with a 16% higher risk of death from any cause — a stronger predictor than blood pressure.
How to Measure Your Grip Strength
Use a hand dynamometer: stand or sit with your elbow at 90 degrees, squeeze as hard as possible for 3–5 seconds, and record the peak reading. Test both hands and record the dominant hand result. Take 3 measurements and use the average or best reading. Standardized protocol calls for keeping your shoulder neutral and not bracing the arm against your body.
Understanding the Normative Data
The reference values in this tool are drawn from the NHANES (National Health and Nutrition Examination Survey), which measured grip strength in a large, nationally representative U.S. population sample. Mean grip strength peaks in the mid-30s for men and late 20s to early 30s for women, then gradually declines with age — this is called sarcopenia.
Percentile Rankings
Percentile rankings are estimated using normative distribution data. The 50th percentile is average for your age and sex group. Above the 75th percentile is above average strength. Below the 25th percentile indicates below average strength and may warrant increased attention to strength training.
How to Improve Your Grip Strength
The most effective grip strength training includes: heavy compound pulling exercises (deadlifts, barbell rows, pull-ups), which train the grip under high loads; farmer's carries and loaded holds; pinch grip training with weight plates; and dedicated grip tools like thick-bar training or hand grippers. Most people see significant grip strength improvements within 6–8 weeks of dedicated training.

Why does grip strength predict health outcomes?
Grip strength is a proxy measure of overall skeletal muscle strength. Research from the Prospective Urban Rural Epidemiology (PURE) study and other large cohorts shows that low grip strength is associated with higher risk of cardiovascular disease, all-cause mortality, disability, and cognitive decline — independent of other risk factors. It is one of the best single-measurement predictors of functional health as we age.
What device do I need to measure grip strength?
Grip strength is measured with a hand dynamometer, typically in the dominant hand with the elbow at 90 degrees. Medical-grade dynamometers cost $200+, but consumer versions (Camry, Jamar) are available for $30–$80 and are accurate enough for self-monitoring. Some gyms and physical therapy offices also offer testing.
What grip strength normative data does this tool use?
The reference values are derived from the NHANES (National Health and Nutrition Examination Survey) population study and peer-reviewed literature on handgrip strength norms across age groups. Values represent mean grip strength by age decade and sex in healthy adults.
How can I improve my grip strength?
Grip strength improves with compound pulling exercises (deadlifts, rows, pull-ups), specific grip training (plate pinches, farmer's carries, towel pull-ups), and dedicated tools like hand grippers and wrist rollers. Results typically appear within 4–8 weeks of consistent training.
Is grip strength the same as forearm strength?
Grip strength primarily measures finger flexor and intrinsic hand muscle strength, but it also reflects forearm muscle contribution. It correlates strongly with overall upper body strength and general muscle mass, making it useful as a simple whole-body strength screening tool.
