What is the Wilks Score?
The Wilks Score (or Wilks Coefficient) is a formula used in powerlifting to compare the relative strength of lifters across different body weights. Developed by Robert Wilks in 1994, it has become the standard method for determining "best lifter" awards at powerlifting competitions worldwide.
How the Wilks Formula Works
The Wilks formula uses a 5th-degree polynomial based on bodyweight to create a coefficient. This coefficient normalizes strength across different weight classes, allowing fair comparison between, for example, a 60kg lifter and a 120kg lifter.
Wilks Score = (500 / Coefficient) × Total (kg)
Wilks Score Standards

- Novice: 300-349
- Beginner: <300
Women's Standards
- Elite: 450+
- Advanced: 350-449
- Intermediate: 300-349

- Beginner: <250
Wilks vs DOTS vs IPF Points
Wilks (1994) is the classic standard. DOTS (2019) is commonly used in USAPL/USPA and aims to reduce bias at extreme weight classes. The IPF uses IPF Points (Goodlift) as its official standard. Each is valid for comparing relative strength, depending on federation context.
Pro Tip: To improve your Wilks score, focus on increasing your total while maintaining (or slightly reducing) bodyweight. A higher total at the same bodyweight always means a higher Wilks score.
