Powerlifting weight classes are defined in kilograms and vary slightly depending on the federation and age division. The International Powerlifting Federation (IPF), which governs most national and international competition, uses eight weight classes for men and eight for women in the open (adult) division. Younger lifters get two additional lighter classes.
Men’s Weight Classes
The standard men’s classes in IPF-affiliated competition are:
- 59 kg (up to 130 lbs)
- 66 kg (up to 145.5 lbs)
- 74 kg (up to 163 lbs)
- 83 kg (up to 183 lbs)
- 93 kg (up to 205 lbs)
- 105 kg (up to 231.5 lbs)
- 120 kg (up to 264.5 lbs)
- 120+ kg (no upper limit)
Each class includes everyone up to that weight. A lifter weighing 83.00 kg competes at 83 kg, but a lifter at 83.01 kg moves up to the 93 kg class. The boundaries are strict to the hundredth of a kilogram.
Women’s Weight Classes
The women’s classes follow the same structure with lighter boundaries:
- 47 kg (up to 103.5 lbs)
- 52 kg (up to 114.5 lbs)
- 57 kg (up to 125.5 lbs)
- 63 kg (up to 139 lbs)
- 69 kg (up to 152 lbs)
- 76 kg (up to 167.5 lbs)
- 84 kg (up to 185 lbs)
- 84+ kg (no upper limit)
Extra Classes for Younger Lifters
Sub-junior (typically 14 to 18) and junior (typically 19 to 23) divisions add two lighter weight classes on each side. Men get a 53 kg class below the usual 59 kg starting point, giving juniors nine total classes. Women get a 43 kg class below the usual 47 kg starting point, also totaling nine. These exist because younger athletes, especially teenagers, are often smaller than the lightest open-division class would accommodate.
Master divisions (age 40 and up) generally use the same eight classes as the open division.
How Weigh-Ins Work
Lifters must weigh in before competition, and the timing depends on the federation. Most IPF-affiliated meets use a two-hour weigh-in, meaning you step on the scale two hours before your session starts. Some other federations use a 24-hour weigh-in, where you weigh in the day before you lift.
This distinction matters because it determines how much weight you can realistically cut and recover from. With a 24-hour weigh-in, lifters have enough time to rehydrate, eat, and restore energy before lifting. With a two-hour window, aggressive water cuts are risky because there simply isn’t time to bounce back. Many lifters competing under two-hour rules stay closer to their actual weight class rather than cutting heavily.
Choosing the Right Weight Class
Your ideal class is the one where you’re competitive without sacrificing too much strength to get there. Most coaches suggest competing at a weight you can maintain comfortably, then cutting only a small amount of water weight for the weigh-in. A lifter who walks around at 78 kg, for example, could reasonably compete at 76 kg (women’s) or 74 kg (men’s) with a modest cut, but trying to squeeze into 69 kg or 66 kg would likely hurt performance more than the competitive advantage is worth.
If you’re between classes and not sure which direction to go, consider where your strength-to-bodyweight ratio is best. Moving up a class means you’ll face bigger competitors, but you’ll also be better fueled and less drained on meet day. Moving down means a potential size advantage, but only if you can still hit your numbers after cutting.
Other Federations
The IPF classes listed above are the most widely used because national federations in most countries (USA Powerlifting, Powerlifting America, British Powerlifting, and dozens of others) follow IPF standards. However, some non-IPF federations use slightly different class structures. The WRPF, for instance, has historically used different boundaries, and some smaller organizations still use older class breakdowns from before the IPF restructured its classes.
If you’re entering a specific meet, check that federation’s rulebook to confirm the exact classes. But for the vast majority of competitive powerlifting worldwide, the eight classes listed above are what you’ll encounter.
