Your relative strength scores
Both scores let you compare strength fairly across different bodyweights — higher scores mean better relative strength, regardless of the number on the scale.
Why relative strength scores exist
Raw totals favour heavier lifters, since more bodyweight generally allows more absolute strength. Wilks and DOTS adjust for bodyweight so lifters of any size can be compared fairly.
Wilks vs. DOTS
Wilks is the older, more established scoring system used in powerlifting for decades. DOTS is a newer formula developed to correct some accuracy issues at the extremes of the bodyweight range.
Which one should I use?
DOTS has largely replaced Wilks in competitive powerlifting because it's more accurate across the full bodyweight range — we calculate both so you can use whichever your federation prefers.
The formulas
# Wilks (polynomial coefficient × total) Coefficient = 500 / (a + bx + cx² + dx³ + ex⁴ + fx⁵) where x = bodyweight(kg), coefficients differ by sex Wilks score = coefficient × total(kg) # DOTS (polynomial coefficient × total) Same structure, updated coefficients, sex-specific DOTS score = coefficient × total(kg)
Both use fifth-degree polynomial coefficients published by their respective federations. We use the standard published constants for each.
Common questions
Roughly: 300+ is solid intermediate strength, 400+ is advanced, 500+ starts to enter elite territory — though this varies by federation and lift selection.
Yes — enter just that lift's weight as the 'total' to get a relative strength score for one lift, like a squat-only or deadlift-only comparison.
Your score moves with both your total and your bodyweight — a heavier total obviously helps, but so does lifting the same total at a lower bodyweight.
