Wilks score

Wilks coefficient
0.64

A 200 kg total means something very different for a 60 kg lifter than for a 120 kg lifter. The Wilks coefficient levels the field by scaling your total against a body-weight curve, so the Wilks score is the standard way meets rank lifters across weight classes.

How this is calculated

The Wilks coefficient is 500 divided by a fifth-order polynomial of body weight in kilograms, using the sex-specific constants published by Robert Wilks in 1994. Your Wilks score is that coefficient multiplied by your total lifted. Higher is better, and the curve is tuned so a world-class total scores near 500 regardless of weight class.

How to use

  1. Enter your body weight in kilograms and select your sex.
  2. Enter your total lifted in kilograms (squat plus bench plus deadlift).
  3. Read your Wilks coefficient and score.

Examples

  • Male, 90 kg, 600 kg total: Coefficient 0.64, Wilks score 383.04
  • Female, 60 kg, 300 kg total: Coefficient 1.11, Wilks score 334.47

FAQ

What is a good Wilks score?
Roughly, 300 is a solid intermediate lifter, 400 is advanced, and 500 or more is elite. The exact bar depends on the federation and era.
How is Wilks different from DOTS?
Both normalize strength across body weights, but DOTS uses a newer set of coefficients and no longer separates by sex in the same way. Many federations have moved to DOTS, while Wilks remains widely referenced.
