Compare powerlifting strength across body weights
The Wilks Score is a coefficient used in powerlifting to compare the relative strength of lifters across different body weight classes. It allows fair comparison between a 60kg lifter and a 120kg lifter by accounting for the natural strength advantages of heavier bodyweights.
The Wilks formula calculates a coefficient based on your body weight, then multiplies your total lifted weight (squat + bench + deadlift) by this coefficient. The result is a normalized score that represents your strength relative to all lifters, regardless of weight class.
Level | Men | Women | Description |
---|---|---|---|
Beginner | < 250 | < 200 | 0-1 year training |
Novice | 250-350 | 200-275 | 1-2 years training |
Intermediate | 350-400 | 275-325 | 2-3 years training |
Advanced | 400-450 | 325-375 | 3-5 years training |
Elite | 450-500 | 375-425 | National level competitor |
World Class | 500+ | 425+ | International competitor |
The Wilks formula was updated in 2020 to Wilks2 with new coefficients, but the original Wilks remains widely used. Some federations now use alternative formulas like IPF GL Points or Dots. This calculator uses the original Wilks formula, which is still the most recognized standard for comparing strength across weight classes.
To increase Wilks score: Focus on total strength (squat + bench + deadlift), address weak lifts first, consider optimal body composition (lean muscle mass), compete in appropriate weight class, follow periodized training program, prioritize recovery and nutrition. Lighter lifters often have higher Wilks due to favorable strength-to-weight ratios.
For men: 300+ is respectable (recreational lifter), 350-400 is competitive (regional level), 400-450 is advanced (national qualifier), 450-500 is elite (national medalist), 500+ is world class. For women: 250+ is respectable, 300-350 is competitive, 350-400 is advanced, 400-450 is elite, 450+ is world class. Most recreational lifters plateau at 250-350 (men) or 200-300 (women).
The Wilks formula compensates for the fact that heavier lifters have natural strength advantages but not proportionally. A 60kg lifter totaling 400kg has higher relative strength than a 100kg lifter totaling 600kg, reflected in higher Wilks (higher coefficient for lighter weights). This is why pound-for-pound rankings favor lighter athletes across all sports.
Only if you're carrying excess body fat (>20% men, >30% women). Losing fat while maintaining strength increases Wilks. However, don't sacrifice muscle mass for a higher score. Most competitive lifters find their optimal weight class where they're lean but not depleted. Dropping too much weight usually decreases absolute strength more than the coefficient compensates.
Yes, though some federations have adopted newer formulas. IPF uses IPF GL Points, some use Dots or Wilks2. However, Wilks remains the most widely recognized and used system globally for comparing lifters across weight classes. It's the standard reference when discussing relative strength outside of specific federation contexts. Most lifters still calculate and compare Wilks scores.
