Wilks Score for Powerlifters: Compare Your Strength Across All Weight Classes
Published: Fitness & Training Guide
Ever wondered how a 148 lb lifter stacks up against a 308 lb heavyweight? The Wilks Score answers this exact question—it's the gold standard for comparing pound-for-pound strength across all bodyweight classes in powerlifting. Whether you're tracking your progress, competing at meets, or simply want to know where you stand among lifters worldwide, understanding your Wilks score reveals your true strength potential. Here's everything you need to know about this game-changing metric.
What is the Wilks Score?
The Wilks Score (officially the Wilks Coefficient or Wilks Formula) is a mathematical formula used in powerlifting to compare the relative strength of lifters across different bodyweight classes. It calculates a normalized score that accounts for the non-linear relationship between bodyweight and lifting capacity, allowing fair comparison between a 132 lb lifter and a 308 lb lifter.
Created by: Robert Wilks, an Australian powerlifting coach and statistician, in 1996
Purpose: Determine the "pound-for-pound" strongest lifter regardless of weight class, used to award "Best Lifter" at competitions and compare performance across divisions.
⚡ Quick Facts for Powerlifters
- ✓ Universal Standard: Compare your strength to any lifter, any weight class
- ✓ Competition Use: Determines "Best Lifter" awards at powerlifting meets
- ✓ Goal Setting: 400 Wilks = intermediate, 500 = advanced, 600 = world-class
- ✓ Track Progress: More meaningful than raw totals for long-term development
- ✓ Multiple Formulas: Wilks, Wilks2, DOTS all serve the same purpose
Why Wilks Score Matters for Athletes
For strength athletes, the Wilks Score provides critical context that raw numbers can't. A 1,500 lb total sounds impressive, but is it elite or merely good? That depends entirely on your bodyweight—and this is where Wilks becomes invaluable.
Impact on Training and Competition
- Strength athletes: Reveals true pound-for-pound strength development beyond absolute numbers
- Competitive powerlifters: Determines best lifter awards and allows cross-weight-class comparisons
- Bodybuilders and CrossFit athletes: Benchmarks relative strength independent of body composition changes
- Long-term progression: Tracks strength improvements even when bodyweight fluctuates during bulking/cutting cycles
Research from Auburn University and the National Strength and Conditioning Association has validated that normalized strength scores like Wilks provide more accurate assessments of training effectiveness than absolute load progressions alone, particularly when athletes change weight classes or body composition.
Why the Wilks Score Exists
Simply dividing total weight lifted by bodyweight (relative strength ratio) doesn't fairly compare lifters across weight classes due to the square-cube law. Heavier lifters lift more in absolute terms but have lower bodyweight ratios. The Wilks formula mathematically corrects for this scaling relationship.
Example of the Problem Without Wilks
Lifter A - 148 lb weight class:
Total: 1,200 lbs | Ratio: 8.11× bodyweight
Lifter B - 308 lb weight class:
Total: 2,100 lbs | Ratio: 6.82× bodyweight
Based on simple ratios, Lifter A appears stronger. However, this ignores that heavier lifters face inherent biomechanical disadvantages. The Wilks formula mathematically adjusts for these differences to determine who is truly stronger pound-for-pound.
📊 What Research Shows
Sport scientists at the Australian Institute of Sport analyzed thousands of powerlifting performances and confirmed that the Wilks formula accurately predicts competitive outcomes across weight classes better than simple bodyweight ratios. Their research validated that lighter lifters possess inherent leverage advantages that must be mathematically corrected for fair comparison.
Practical takeaway: Wilks isn't arbitrary—it's statistically derived from real-world competition data to ensure accurate strength comparisons.
How the Wilks Score is Calculated
The Wilks coefficient is calculated using a polynomial formula with different constants for men and women:
Step 1: Calculate Wilks Coefficient
Coefficient = 500 / (a + b×BW + c×BW² + d×BW³ + e×BW⁴ + f×BW⁵)
Where BW = bodyweight in kilograms, and a, b, c, d, e, f are gender-specific constants
Step 2: Calculate Wilks Score
Wilks Score = Total Lifted (kg) × Coefficient
Don't worry about manual calculation—FitnessRec and online calculators do this instantly.
Simplified Example
Male lifter: 165 lbs (75 kg) with 1,200 lb (545 kg) total
1. Wilks coefficient for 75 kg male ≈ 0.7186
2. Wilks Score = 545 × 0.7186 ≈ 391.6
Male lifter: 275 lbs (125 kg) with 1,900 lb (862 kg) total
1. Wilks coefficient for 125 kg male ≈ 0.5672
2. Wilks Score = 862 × 0.5672 ≈ 488.9
Despite the lighter lifter having a higher bodyweight ratio (7.27× vs 6.91×), the heavier lifter has a superior Wilks score (488.9 vs 391.6), indicating greater pound-for-pound strength when biomechanics are properly accounted for.

Important: Wilks2 and DOTS Formulas
As of 2020, many federations have transitioned from the original Wilks formula to updated versions:
- Wilks2: Updated Wilks formula using more recent data (2020+)
- DOTS: Alternative formula gaining popularity, considered more accurate at extreme bodyweights
- IPF Points: International Powerlifting Federation's proprietary formula
Different formulas produce slightly different scores, so always compare scores calculated with the same formula. FitnessRec supports multiple formulas for accurate tracking.
Limitations of the Wilks Score
1. Gender Separation
Wilks scores cannot be directly compared between men and women due to different formulas and coefficients. A 500 Wilks male and 500 Wilks female represent different absolute strength levels.
2. Extreme Bodyweights
The formula was derived from data clustered around average bodyweights. Very light (<110 lbs) or very heavy (>350 lbs) lifters may have slightly inaccurate coefficients.
3. Doesn't Account for Age
A 50-year-old with a 500 Wilks is more impressive than a 25-year-old with the same score, but the formula doesn't adjust for age. Separate age-adjusted formulas (like Glossbrenner) exist for masters divisions.
4. Federation and Equipment Differences
Wilks scores from equipped lifting (suits, wraps) cannot be compared to raw scores. Additionally, different federation depth standards affect totals.
5. Leverage and Proportions Not Considered
Two lifters at the same weight with different limb lengths and torso proportions will have different biomechanical advantages, but Wilks treats them equally.

- Genetic potential approaching maximum
- World-class competitive level
- Requires exceptional genetics, coaching, and dedication
- Very few lifters ever achieve this level

Common Questions About Wilks Score
Is a higher Wilks always better?
In powerlifting, yes. Wilks measures pound-for-pound strength. However, in sports requiring absolute strength (strongman, open-class powerlifting), raw totals matter more than Wilks.
Should I lose weight to improve my Wilks?
Only if losing fat, not muscle. Cutting bodyweight while maintaining strength improves Wilks. However, losing muscle mass decreases both absolute strength and Wilks.
What's a good Wilks score for a natural lifter?
400-450 Wilks is highly respectable for a natural lifter with several years of training. 500+ Wilks natural is exceptional and typically requires near-genetic-maximum development.
How quickly can I improve my Wilks?
- Year 1: 100-150 Wilks gain (beginner gains)
- Year 2-3: 50-80 Wilks gain per year
- Year 4-6: 20-40 Wilks gain per year
- Year 7+: 10-20 Wilks gain per year (diminishing returns)
How do I track my Wilks score in FitnessRec?
Automatic calculation built-in. Simply log your bodyweight and your squat, bench, and deadlift 1RMs in the fitness tracking section.
