What Wilks does
The Wilks coefficient was the dominant way to compare powerlifters across weight classes from the early 1990s through the late 2010s. It is a fifth-degree polynomial of bodyweight that produces a multiplier; total in kilograms times the multiplier equals the Wilks score.
Most modern federations have shifted to DOTS or the IPF-GL coefficient, which behave better at the extremes. Wilks is still widely quoted, especially for historical meet results.
Frequently asked questions
What is a Wilks score?
The Wilks coefficient is a formula developed by Robert Wilks in the early 1990s to compare powerlifting totals across weight classes and sexes. Your total in kilograms is multiplied by a bodyweight-dependent coefficient; the result is a single number that approximates 'pound-for-pound' strength.
What is a good Wilks score?
Roughly: 250–300 is solid for a regular gym lifter, 350+ is competitive at the local meet level, 400+ is national-level, and 500+ is world-class. The scale runs the same for men and women — the bodyweight coefficients are different to compensate.
Is Wilks still used?
Less so. Most federations including the IPF have moved to DOTS or the newer IPF-GL coefficient, which avoid some of the bias Wilks shows at the very low and very high ends of bodyweight. Wilks is still the most-recognised number historically and is what most older meet results are scored in.
