What is the Wilks score?

The Wilks score (also called the Wilks coefficient) is a formula used in powerlifting to compare lifters of different body weights on a level playing field. It was developed by Robert Wilks of Powerlifting Australia and is widely used in sanctioned competitions.

Formula

Wilks Score = Coefficient × Total lifted (kg)

The coefficient is derived from a 5th-degree polynomial fitted to body weight, with separate constants for male and female athletes.

Interpreting your score

Below 200: Beginner: just starting out
200–299: Novice: developing solid base
300–399: Intermediate: competitive at local meets
400–499: Advanced: competitive at national level
500+: Elite: world-class performance

Why use Wilks instead of raw total?

Heavier lifters naturally lift more weight due to their larger muscle mass. The Wilks coefficient adjusts for body weight so a 60 kg lifter can be fairly compared to a 100 kg lifter. It levels the playing field across weight classes.

Score range	Level
Below 200	Recreational lifter
200–300	Competitive amateur
300–400	National-level competitor
400+	Elite

Wilks vs. Dots vs. IPF GL comparison

The Dots coefficient (introduced 2020) was developed to address perceived biases in the Wilks formula at extreme body weights, where the original polynomial over-rewards very light or very heavy lifters. The IPF GL (Good Lift) points formula replaced Wilks at World and European Powerlifting Federation championships in 2019, and is now the standard for international competition. Many national federations still use Wilks for historical comparability.

How to use your Wilks score

Compare your score across body weight changes to measure genuine strength progress independent of weight class.
In multi-lifter meets, overall best lifter awards use Wilks (or IPF GL) to determine the winner across weight classes.
Use online powerlifting rankings and communities to benchmark your score against other lifters globally.
