What Are Wilks, DOTS, and IPF GL Scores?
All three are bodyweight-adjusted scoring systems used in powerlifting to compare lifters across different weight classes. A 148 lb lifter totaling 1,200 lbs and a 242 lb lifter totaling 1,600 lbs — who is relatively stronger? These formulas answer that question by normalizing the total against bodyweight.
Wilks vs DOTS vs IPF GL — What's the Difference?
| System | Used By | Notes |
|---|---|---|
| Wilks | Legacy standard, still widely referenced | Original bodyweight coefficient (updated 2020). 5th-degree polynomial. |
| DOTS | USAPL, USPA, many federations for Best Lifter | Developed as a more balanced alternative. 4th-degree polynomial. |
| IPF GL | IPF official scoring since 2020 | Exponential curve fitted to world-class performances. Separate coefficients for Classic and Equipped. |
Score Benchmarks
These are approximate ranges for Wilks scores. DOTS and IPF GL follow similar distributions.
| Wilks Score | Level |
|---|---|
| 200–300 | Recreational to club-level lifter |
| 300–350 | Competitive at local and state meets |
| 350–400 | Strong state/regional competitor |
| 400–450 | Nationally competitive |
| 450–500 | Elite — national podium contender |
| 500+ | World-class |
Frequently Asked Questions
Which score should I use?
Check what your federation uses for Best Lifter awards — that's the one that matters for you. If you're just tracking personal progress, any of them work. DOTS and IPF GL are considered more balanced across extreme bodyweight classes.
Why does this say "IPF GL (Classic)"?
The IPF publishes separate GL coefficients for Classic (raw) and Equipped divisions. This calculator uses the Classic coefficients, which is what the vast majority of lifters need.
