Comparing a light lifter with a heavy one

Works out Wilks points from bodyweight and total, so lifters in different weight classes can be compared.

Strength grows with bodyweight but not in proportion to it: an athlete twice as heavy does not lift twice as much. So comparing totals directly is useless, and total divided by bodyweight systematically flatters the lighter classes.

The Wilks coefficient solves it with a fifth-degree polynomial fitted to competition results. Multiplying a total by the coefficient produces a number comparable across classes and across sexes.

A rough placement of the result

What to keep in mind

The original Wilks coefficient is used. DOTS, Wilks-2 and IPF GL run on their own coefficient tables and give different numbers.
The polynomial is fitted for bodyweights of roughly 30 to 220 kilograms; outside that range it is not defined.

FAQs

What is the Wilks coefficient?

A multiplier that puts a powerlifting total on a comparable footing regardless of bodyweight. It comes from a fifth-degree polynomial in kilograms.

What Wilks score is good?

Three hundred is a solid competitive amateur, four hundred is elite, and five hundred and above belongs to the strongest in the world.

How does DOTS differ from Wilks?

It is a later formula with different coefficients fitted to modern results. It produces different numbers, and Wilks points cannot be compared with DOTS points.

Does Wilks apply to single lifts?

It was derived for the three-lift total, though people apply it to single lifts for a rough comparison. Such a comparison carries no official weight.

Worked example

Ninety kilos, a 550 total

Input: Male at 90 kg, 550 kg total

Output: 351.1 points at a coefficient of 0.6384

Note: The same total from a 75 kg lifter would carry a coefficient near 0.70 and almost 385 points. Fifteen kilograms of bodyweight is worth more than thirty points.
