The Wilks Score Explained
The Wilks score is a formula used in competitive powerlifting to compare lifters across different body weights. It normalizes your powerlifting total (squat + bench press + deadlift) relative to your body weight using a polynomial equation, producing a single number that allows fair comparison between a 60 kg lifter and a 120 kg lifter.
How the Formula Works
The Wilks formula uses a fifth-degree polynomial to create a coefficient based on body weight. This coefficient is multiplied by your total to produce the Wilks score. Separate sets of coefficients are used for male and female lifters because the relationship between body weight and strength potential differs between sexes. The formula was developed by Robert Wilks and has been the standard comparison method in the International Powerlifting Federation for decades.
Interpreting Your Score
General benchmarks for Wilks scores:
- Under 150 - Beginning stages of training
- 150-250 - Novice level, consistent training is paying off
- 250-350 - Intermediate, a solid base of strength
- 350-450 - Advanced, competitive at local and regional meets
- 450+ - Elite, competitive at national and international level
Limitations to Keep in Mind
The Wilks formula tends to slightly favor middle-weight lifters and may not perfectly normalize at extreme body weights. Alternative formulas like DOTS and IPF GL Points have been developed to address these limitations. However, Wilks remains the most widely recognized and used coefficient in the sport, making it the standard reference point for comparing powerlifting performance.
