Squat Depth Explained: How Low Should You Actually Go?

Depth is measured at the hip, not the knee. "Parallel" means the crease of your hip drops to the same level as the top of your knee. "Below parallel" means the hip crease drops below that line.

Powerlifting judges this strictly; for most lifters, hitting at least parallel with control is a solid standard.

More depth means more range of motion, which generally means more muscle worked — particularly the glutes and quads. So depth is valuable.

But "as deep as possible" isn't the goal if you can't keep a neutral spine and your heels down. The best depth is the deepest you can reach while holding good position.

The big ones are ankle and hip mobility, your individual anatomy (femur and torso length change what a good squat looks like), bracing, and stance width.

If your heels lift or your lower back rounds at the bottom ("buttwink"), you've passed the depth your current mobility supports.

Work to the deepest position where your heels stay planted and your spine stays neutral. Widening your stance slightly or pointing your toes out often unlocks more depth.

Temporarily elevating your heels (lifting shoes or small plates) can help while you build ankle mobility.

Depth is hard to judge by feel, and a mirror lies. Film from the side, level with your hips.

FormLens measures your hip and knee angles and gives you an objective depth read on every rep, so you know exactly when you hit parallel — no guessing, no debate.
