One of the most common questions in powerlifting is simple: how low do you actually have to squat for it to count? It's one of the more common questions I hear from powerlifters when they're considering their first meets.
The rule sounds straightforward, but in practice, it creates more confusion than most lifters expect. Here's what to know.

What the Rule Book Says
In most powerlifting federations, the squat depth rule states that the hip crease must descend below the top surface of the knee. Simple, right?
Break parallel, stand back up, get white lights. In reality, the rule uses anatomical landmarks, not painted lines, which is why interpretation becomes a challenge. That's where some lifters get caught up.
The team at Powerlifting Technique has several helpful guides for first-time powerlifting meets, including a powerlifting course taught by the head coach of Team Canada Powerlifting. That's a solid place to start if you want to make sure your lifts count in competition.
Why Depth Is Often Debated
Lifters frequently ask questions like:
- What if my knees are more rounded?
- Where exactly is the “top surface” of the knee?
- Where does the hip crease officially begin?
- Does body structure change how depth looks?
These are valid questions. Judges are not using measuring tools. They are evaluating depth in real time based on visible movement and the relationship between the hip crease and the knee.
What Judges Actually Look For
When referees call depth, they focus on one relationship: does the hip crease clearly descend below the top of the knee?
More specifically, judges look at where the hip joint folds as you descend, the lowest visible point of the hip crease, the highest visible point of the knee, and whether the crease is unmistakably lower than that knee line.
If it is close, it becomes risky. If it is clearly below, you remove doubt.
Many red lights come from squats that are extremely close. Lifters often train at gym depth, which may not match competition depth. Train with the intent to make depth obvious, not arguable.
Body Structure and Depth Perception
Different body types can make depth look different. Larger quads can make depth appear shallower from the front. Long femurs can require more hip travel. Stance width changes what depth looks like from the side.
Despite these differences, the standard does not change. The hip crease must still break below the knee.
If you plan to compete, train to competition depth year-round. Film from the side at knee height, practice hitting consistent depth under fatigue, and avoid cutting squats high in training. And reference the official federation information and the rulebook source, starting with the IPF rulebook and official resources.
Of course, sometimes reading the rule isn't enough. Seeing diagrams and video examples makes depth much clearer.

The bottom line is this: To pass a squat in competition, your hip crease must clearly descend below the top surface of the knee.
If it is questionable, you risk red lights. If it is obvious, you protect your lift. In powerlifting, strength gets the bar moving. Depth makes it count.
