10mm vs 13mm weightlifting belt: which should I get?

Choose a 10 mm weightlifting belt if you want a belt that breaks in quickly and feels comfortable for mixed training, CrossFit and Olympic lifting. Choose a 13 mm belt for maximum stiffness and core bracing in heavy squats and deadlifts, especially in powerlifting. A 13 mm leather belt takes longer to break in and can feel harder on the ribs and hips. Both are commonly 4 inches wide, and the right choice depends on your lifts, your torso and your federation rules.

Story (illustrative): Hamza does CrossFit and Olympic lifting. He bought a stiff 13 mm belt because a powerlifter recommended it, but it dug into his ribs during cleans. He switched to a 10 mm belt for daily training and kept the 13 mm belt for heavy squat days.

Comparison

A 10 mm belt ($50 to $130, estimate) usually costs a little less than a 13 mm belt ($60 to $160), and both last 5 to 10+ years. The 10 mm belt wins on break-in speed and comfort, and the 13 mm belt wins on stiffness and core bracing. Choose 10 mm for general gym work and Olympic lifting, and 13 mm for powerlifting. The table below compares price, lifespan and use.

Pros and cons: A 10 mm belt breaks in easily, feels comfortable and suits many lifts, but it is less rigid at maximum loads. A 13 mm belt gives maximum rigidity and bracing for the heaviest squats and deadlifts, but it needs a long break-in and is less comfortable.
