6.5mm vs 10mm vs 13mm Lifting Belts: Which Thickness Is Right for You?

One of the first decisions you'll make when buying a lifting belt is choosing the thickness.

If you've started researching belts online, you've probably come across three common options:

6.5mm
10mm
13mm

So which one is best?

The answer depends on your training style, your experience and what you personally find comfortable.

There isn't a "best" thickness for everyone. Each option has its own feel, and many lifters simply choose the one that suits the way they like to train.

Why Belt Thickness Matters

The thickness of a lifting belt changes how the belt feels when you wear it.

Generally speaking:

Thinner belts tend to feel more flexible.
Thicker belts tend to feel more rigid.

Neither is automatically better.

It's simply about finding the balance that suits your training and preferences.

6.5mm Lifting Belts

A 6.5mm belt is the most flexible of the three options.

Many lifters choose this thickness because it often feels comfortable sooner and allows greater freedom of movement.

Many lifters choose a 6.5mm belt if they:

Train for general strength.
Prefer a more flexible belt.
Are buying their first lifting belt.
Want a belt that's comfortable across a variety of exercises.

For people who value comfort above maximum rigidity, 6.5mm is often a popular choice.

10mm Lifting Belts

A 10mm belt is often considered the middle ground.

It provides a balance between flexibility and rigidity, making it a versatile option for many different training styles.

Many lifters choose a 10mm belt because they:

Perform a variety of compound lifts.
Want a balance of comfort and firmness.
Prefer one belt for most types of strength training.

If you're unsure which thickness to choose, many people find that a 10mm belt offers a good balance.

13mm Lifting Belts

A 13mm belt is the thickest and most rigid option.

Many experienced lifters enjoy the solid feel of a thicker belt, particularly during heavy strength training.

Because of its rigidity, a 13mm belt may also take longer to feel fully broken in compared to thinner belts.

Many lifters who choose 13mm belts:

Prefer a firmer feel.
Enjoy maximum belt rigidity.
Have previous experience using lifting belts.

Comfort is highly individual, so what feels great for one lifter may not suit another.

Which Belt Thickness Is Best for Beginners?

Many beginners ask whether they should start with a thinner belt.

There isn't one correct answer.

Some beginners appreciate the flexibility of a 6.5mm belt.

Others prefer the balanced feel of a 10mm belt.

The best choice depends on what feels comfortable and suits your training goals.

We definitely do not recommend beginners get a 13mm belt, as you may be surprised just how rigid it is and how challenging it can be to get on and off.

Does a Thicker Belt Mean It's Better?

Not necessarily.

A thicker belt isn't automatically "better."

Some lifters prefer the flexibility of a thinner belt, while others enjoy the feel of a more rigid belt.

Choosing the right thickness is about finding the option that you'll enjoy using consistently—not simply selecting the thickest available.

Which Thickness Should You Choose?

Here's a simple comparison.

Choose a 6.5mm belt if you:

Prefer flexibility.
Want greater freedom of movement.
Like a softer feel.
Train for general strength or fitness.

Choose a 10mm belt if you:

Want one versatile belt.
Prefer a balance of comfort and rigidity.
Perform a wide variety of compound lifts.

Choose a 13mm belt if you:

Prefer maximum rigidity.
Like a firmer feel.
Have experience training with lifting belts.

Common Mistakes to Avoid

Assuming Thicker Is Always Better

The thickest belt isn't automatically the best choice.

Comfort and personal preference matter.

Buying Based on Someone Else's Recommendation

Your body shape, training style and preferences are unique.

Choose a belt that suits you—not simply the one someone else uses.

Ignoring Comfort

A belt you enjoy wearing consistently is often a better choice than one that spends most of its time in your gym bag.

Rushing Your Decision

A lifting belt is something many people use for years.

Taking the time to choose the right thickness is worthwhile.

Final Thoughts
