Choosing the Right Belt: Why Size Matters
When it comes to picking out a belt, size is more important than you might believe. If you use a weight lifting belt that is too big, it can make you uncomfortable, lower your performance, and possibly hurt you.
This is how to make a choice:
How much of a belt should I get?
To begin, measure your waist in inches and add two inches. If your waist is 32 inches, you should get a belt that is 34 to 36 inches long. The 90 belt size in the US is squarely in the middle.
Need a belt that fits in the middle?
A belt that is medium-sized is normally between 85 and 95 cm long. So, a 90 cm belt is right in the middle of that range, making it a popular and flexible choice. Whether you're dressing up or need a secure fit for daily wear, a leather best belt in this size offers both style and functionality for a wide range of body types.
Using our reference to the size of weight lifting belts
At fightsense.com, we suggest picking a belt size that keeps the central hole in line with your waist while the belt is fastened. This ensures even support and full core engagement during lifts. For example, if you're looking for a 32 waist belt size, make sure it aligns properly to provide the stability you need.

My First Experience with a 90 Belt Size in US:
I didn’t know what a 90 belt size in the US** meant at first. While shopping for a high strength belt, I saw "90 cm" and wasn’t sure if it would fit. After measuring my 33-inch waist, I realized it was the right size.
I found out that 90 cm was the appropriate size for a medium belt for me.
I got my first belt from Fightsense, and it fit well. It fit my waist perfectly, wasn't too tight, and gave me good support while I did deadlifts and squats.
That event taught me how important it is to know sizes instead of just guessing. Now, when someone asks me, "What size belt should I buy?" I always tell them to measure first and then make a sensible choice. For example, an 80 cm belt size might sound right, but without proper measurement, it's easy to end up with something too tight or too loose.
Final Thoughts:
Choosing the right belt doesn’t have to be complicated. A 90 belt size in US is a reliable, medium-range size that works well for many users, especially those in the 32–34 inch waist range. For those needing a slightly larger fit, the 110 cm belt size men's option is a great alternative, offering more flexibility without sacrificing support.
Whether you're hitting the gym or just need everyday support, getting the correct size—like the 110 cm belt size men's—ensures comfort, stability, and performance.At Fightsense, we’re committed to helping you find the perfect fit—because when your belt fits right, everything feels better.
