Wilks, DOTS and IPF GL calculator
Last updated: April 28, 2026
How do you compare a 60 kg athlete's performance with a 110 kg one? That is what allometric coefficients do in powerlifting. They normalize your SBD total based on bodyweight to produce a score comparable across classes.
The calculator shows the three standards in parallel: Wilks (legacy), DOTS (official replacement since 2019), and IPF GL (official IPF coefficient since 2020).
Wilks
DOTS
IPF GL
Indicative level
Wilks is the legacy standard, DOTS replaced it in 2019, IPF GL is the official IPF coefficient since 2020. All three are shown for comparison.
Which formula to use
- DOTS: modern standard for non-IPF federations (USPA, RPS, GPC). Default recommended.
- IPF GL: official coefficient for IPF competitions. Use if you compete IPF.
- Wilks: useful for historical comparison (pre-2019 results). Slightly biased toward heavier lifters.
Indicative DOTS benchmarks
- < 200: beginner.
- 200-300: intermediate.
- 300-400: advanced.
- 400-500: elite (regional/national level).
- 500+: world class.
Coach use
On Unbrokn for strength and powerlifting, DOTS lets you compare athlete progression independent of weight class. Useful to compose competition teams, measure real progression, select internal challengers.
FAQ
Why is my Wilks lower than my DOTS?
Wilks is slightly more generous to heavier athletes, harsher on lighter. DOTS rebalances. On a light lifter, DOTS > Wilks. On a heavy one, opposite.
Does the calculator work in pounds?
Not as is: all coefficients are calibrated in kilograms. Convert before entering: 1 lb = 0.4536 kg.
