Type in your hand dynamometer reading and find out whether your grip tracks younger, older, or right on schedule for your age and sex.
Grip strength is measured with a hand dynamometer — you squeeze a handle as hard as you can for about three seconds, take the best of two or three attempts, and record the result from your dominant hand. It is the cheapest useful muscle test in medicine: no needles, no radiation, and it predicts future disability better than blood pressure predicts stroke.
The reason a hand squeeze says so much is that grip is a proxy for total-body strength. In the PURE study (McGrath et al., The Lancet, 2018), researchers followed roughly 140,000 adults across 17 countries for a median of four years. Every 5 kg drop in grip strength was linked to about a 16% higher risk of dying from any cause and a 17% higher risk of cardiovascular death, even after adjusting for age, sex, education and physical activity.
Normal aging costs about 1–2% of strength per year after age 50, and the decline accelerates through the 60s and 70s. This calculator compares your measured value to age- and sex-specific reference bands drawn from large normative datasets, and applies the low-strength cutoffs used in the EWGSOP2 and Asian Working Group for Sarcopenia consensus statements. It reports the age band your result sits closest to — your "grip age" — plus how far you are from the clinical cutoff.
| Age group | Men average | Men low | Women average | Women low |
|---|---|---|---|---|
| 20–29 | 47.0 | < 38.0 | 29.0 | < 24.0 |
| 30–39 | 48.0 | < 38.0 | 29.5 | < 24.0 |
| 40–49 | 46.0 | < 37.0 | 28.5 | < 23.5 |
| 50–59 | 43.0 | < 35.0 | 27.0 | < 22.5 |
| 60–69 | 39.0 | < 32.0 | 24.5 | < 21.0 |
| 70–79 | 34.0 | < 28.0 | 21.5 | < 18.0 |
| 80+ | 28.0 | < 24.0 | 18.5 | < 15.5 |
Averages track published population norms for adults in high-income countries; the "low" column follows the low-muscle-strength thresholds used to screen for sarcopenia. Asian populations typically score 3–5 kg lower at every age, which is why the Asian Working Group for Sarcopenia publishes separate cutoffs.
The five-times sit-to-stand test needs only a firm chair. Sit with your arms crossed over your chest, stand and sit five times as quickly as you can, and time it. Under 12 seconds is good for most adults; over 15 seconds suggests you should get a real measurement. Take both the sit-to-stand time and your dynamometer reading into any physiotherapy or geriatric assessment.
Measure every three months under the same conditions and you can see the 1–2% annual decline that a single noisy reading would hide.
Grip endurance limits climbing, rowing, tennis and gymnastics. A competitive lifter over 40 typically sits 8–15 kg above their age-band average.
Pre-operative grip strength feeds into frailty scoring and is associated with post-surgical complications and slower recovery.
Women cross the low-strength cutoff roughly a decade earlier than men, which is why strength training matters most between ages 45 and 60.
Yes, and less than most people expect. The dominant hand is typically only 5–10% stronger, so a right-handed person measuring 40 kg on the right hand usually reads 36–38 kg on the left. Always record the dominant hand, but a gap wider than 20% between hands is worth showing to a clinician — it can point to a nerve or tendon problem rather than normal asymmetry.
Absolutely. Sarcopenia and obesity coexist in what clinicians call sarcopenic obesity: body weight looks normal or high, but muscle mass and strength are low. That is one reason grip is used instead of a scale or BMI screen. If your grip lands in the low band while your weight is normal, treat it as a strength-training signal rather than a weight problem.
Grip responds to training like any other muscle, and it also rises when you train bigger upper-body movements. Practical options: farmer's carries with heavy dumbbells for 30–60 seconds per trip, dead hangs from a pull-up bar, heavy dumbbell rows and deadlifts with a double-overhand grip, and a hand gripper taken close to failure 2–3 times weekly. Most beginners see 3–6 kg of improvement in 8–12 weeks.
It forecasts risk — it does not decide your lifespan. The PURE study's 16–17% higher mortality risk per 5 kg drop is a population-level association, and grip is best read as a marker of overall muscle and nervous-system health, not a countdown clock. Two people with identical scores can have very different outcomes depending on fitness, blood pressure and smoking status. Use the number as motivation, not prophecy.
A spring hand gripper gives a rough number only. Digital dynamometers used in clinics are accurate to about ±2–3 kg, and much of the variation between readings comes from posture and effort rather than the device. Sit upright with your elbow at 90 degrees and forearm unsupported, squeeze for three seconds at maximum effort, and always record the best of three attempts on the same device for future comparisons.
