How to Convert Oven Recipes to Air Fryer
The Wilks score is a coefficient used in powerlifting to compare lifters of different body weights on a level playing field.
The basic rule:
- Enter your body weight and competition total (squat + bench press + deadlift)
- The Wilks formula applies a polynomial coefficient based on body weight and sex
- The formula is: Wilks = Total × Coefficient, where the coefficient is calculated from a 5th-degree polynomial
- Higher scores indicate greater relative strength for your body weight
The Wilks score is used by the International Powerlifting Federation (IPF) and most powerlifting federations worldwide to determine best lifter awards and compare performances across weight classes.

Frequently Asked Questions
What is a good Wilks score?
For men: under 300 is beginner, 300-400 is intermediate, 400-450 is advanced, and 450+ is elite. For women: under 250 is beginner, 250-350 is intermediate, 350-400 is advanced, and 400+ is elite.
What is the Wilks formula?
The Wilks coefficient = 500 / (a + b×x + c×x² + d×x³ + e×x⁴ + f×x⁵), where x is body weight in kg and a through f are sex-specific constants. Your Wilks score is then Total (kg) × coefficient.
Is Wilks or DOTS better?
Both are used to compare lifters across weight classes. DOTS is a newer formula that some argue is more accurate for very light and very heavy lifters. The Wilks score remains the most widely recognized and used in competition.
Does the Wilks score work for single lifts?
Yes, you can use any total or single lift value. However, the Wilks score is most commonly applied to the powerlifting total (squat + bench + deadlift). For single lifts, use the single lift weight as your total.
What body weight range does the Wilks formula cover?
The Wilks formula is validated for body weights between 40 kg (88 lbs) and 205 kg (452 lbs) for men, and 40 kg to 150 kg (331 lbs) for women. Outside these ranges, results may be less accurate.
