If you want added security when using a belt, consider pairing your lifting belt with weightlifting shoes to improve your stability, knee sleeves to protect your joints, and lifting straps for your heaviest deadlifts. These accessories stabilize your core, protect your body, and help you maintain proper form under heavy loads.


How to Measure for a Weightlifting Belt

Getting the right size weightlifting belt ensures proper support and stability during your lifts. Follow these steps to measure your waist accurately and find the perfect fit.


Step 1: Measure Your Waist Correctly

Your waist measurement for a weightlifting belt is different from your pant size. To get an accurate number, measure at the right spot and keep the tape level.

  • Stand naturally with a relaxed posture.

  • Wrap a flexible measuring tape around your waist, aligning it with your belly button.

  • Breathe normally and avoid sucking in or pushing out your stomach.

  • Keep the tape snug but not overly tight.

  • Make sure the tape is level and parallel to the floor.


Step 2: Choose the Right Belt Size

Once you have your waist measurement, compare it to the manufacturer’s sizing chart. Belt sizes vary, so always go by your measurement rather than assuming based on your clothing size.

  • Check the brand’s specific sizing chart, as each company has slight variations.

  • If your measurement falls between sizes, size down for a tighter fit or up for more flexibility.

  • Consider your training style — if you’re a powerlifter, you might prefer a snug fit. Still, you may want more flexibility if you’re an Olympic lifter.


Tip: To maximize your stability, protection, and performance during lifts, pair your lifting belt with a powerlifting singlet, high-quality deadlift sleeves, powerlifting shoes, and an AIRWAAV mouthpiece.


Step 3: Test the Fit

Before using your belt in heavy lifts, ensure it fits comfortably and provides the right level of support.

  • Wear the belt and tighten it to a firm but comfortable level.

  • Test your range of motion by bending and bracing — your core should feel supported but not restricted.

  • Adjust if needed to ensure a secure fit without cutting into your sides.


A well-fitted weightlifting belt maximizes your lifting potential, reduces injury risk, and keeps you stable under heavy loads.


Tips for Choosing the Right Belt Size

Finding the perfect weightlifting belt is all about fit and function. Follow these key tips to ensure you get the right size for maximum support and comfort.

  1. Test the fit before buying: Try the belt on and adjust it as if you’re lifting. A proper fit should feel snug without cutting off your breath.

  2. Check tightness: You should be able to slide one finger between the belt and your body. This makes sure you have enough room to breathe and engage your core.

  3. Position it correctly: Place the belt at your navel level for the best support. Adjust slightly higher if you’re using your lifting belt for deadlifts or lower if you’re using your belt for squats.

  4. Avoid over-tightening: If the belt is too tight, it restricts your breathing and movement. Keep a small gap between the belt ends to allow for expansion when you brace.

  5. Adjust for different lifts: To maintain the right level of core stability, use a looser fit for lighter weights and a tighter fit for max-effort lifts.


How to Fix an Improperly Sized Belt

Adjusting your weightlifting belt can improve your comfort and support if your weightlifting belt doesn’t fit correctly. Wear it snugly around your waist, ensuring you can brace properly without feeling restricted. 


If your belt is too tight, loosen it slightly to breathe correctly and have good mobility. If it’s too loose, tighten it enough to maintain your core engagement. 


There are also different types of weightlifting belts: For prong or lever belts, adjust the notches or lever position for a better fit. If using a Velcro belt, ensure the fastener is secure and doesn’t slip during lifts.


If adjustments don’t solve the issue, consider exchanging it for the right size to avoid discomfort and maximize your performance.


Risks of Choosing the Wrong Belt Size

Wearing the wrong size weightlifting belt can lead to discomfort, reduced performance, and even injuries. Here’s what can happen if your belt doesn’t fit correctly:

  • Restricted movement and breathing: A too tight belt limits your range of motion, makes it harder to brace correctly, and can leave you feeling dizzy or uncomfortable during heavy lifts.

  • Insufficient support: If your belt isn’t snug enough, it won’t stabilize your core, leading to weak lifts, excessive spinal movement, and potential strain on your lower back.

  • Misaligned posture: A poor fit can create muscle imbalances, uneven pressure on your core, and a higher risk of injury.

  • Chafing and bruising: A tight belt digs into your ribs and hips, while a loose one shifts around, causing chafing and bruising.

  • Inconsistent performance: Without the right fit, you won’t get the full benefit of core support, making your lifts feel unsteady and affecting your confidence under heavy loads.

A 10 mm belt offers a balance of support and comfort, while a 13 mm belt provides maximum rigidity for powerlifters handling extreme weights.
