Grip Strength Estimator Calculator
Use the Grip Strength Estimator to assess muscular strength in your hands and forearms. Based on age, gender, and measured grip force (via dynamometer), this calculator helps evaluate your strength level and compares it to standardized norms — a key indicator of overall functional fitness and longevity.
Estimate Hand Grip Strength and Compare to Norms
Grip Strength Classification Table
Grip strength is typically measured using a hand dynamometer, then compared to standard tables by gender and age. No exact formula is used, but typical norms are:
Example: Average Grip Strength (Right Hand, kg)
| Age Group | Men (kg) | Women (kg) |
|---|---|---|
| 20–29 | 46.0 | 29.0 |
| 30–39 | 45.0 | 27.5 |
| 40–49 | 44.5 | 26.5 |
| 50–59 | 41.5 | 24.0 |
| 60–69 | 39.0 | 22.0 |

Grip Strength – Calculation Example
Example:
- Gender: Male
- Age: 32
- Measured grip strength: 48 kg
Compared to norms (45 kg for age group 30–39), this is above average.
Grip strength is not just about hand strength — it strongly correlates with total body strength, functional health, and longevity.
It is often used in:
- Physical therapy and rehab
- Geriatric fitness screenings
- Athletic testing in climbing, wrestling, and strength sports
Measuring grip force requires a dynamometer, and values are typically reported in kilograms (kg) or pounds (lbs). This calculator provides context by comparing your score with reference populations.
