How To Measure For BJJ Shorts?

Measuring for BJJ Shorts correctly involves checking waist size, hip measurement, and inseam length, then comparing these numbers against a brand's specific size chart rather than relying on regular clothing sizes. Because Bjj Shorts are designed with stretch fabric and a fitted cut for grappling movement, accurate measurements help ensure the shorts stay secure and comfortable during training without restricting motion.

Brazilian Jiu-Jitsu involves constant stretching, twisting, and ground movement, so a poor-fitting pair of shorts can become a real distraction during training. Unlike everyday shorts, BJJ shorts are cut close to the body and rely on stretch fabric rather than loose sizing, which means measuring correctly matters more than guessing based on regular pant size.

Measure Your Waist Accurately

Start by measuring around the natural waistline, where the shorts will sit during training—not necessarily where regular pants sit.

Use a soft measuring tape and keep it level all the way around, without pulling it too tight. Since most BJJ Shorts use an elastic or drawstring waistband, a small margin of stretch is normal, but the base measurement should still be accurate for a secure fit.

Measure Hip Circumference

Hip measurement matters because BJJ shorts need to move freely during guard positions, takedowns, and ground transitions.

Measure around the widest part of the hips while standing naturally. If your waist and hip measurements fall into different size categories on a brand's chart, sizing up is usually the safer choice for a grappling-specific fit.

Measure Inseam Length

Inseam length affects how the shorts perform during high-guard positions and leg-heavy movements.

To measure, run the tape from the top of the inner thigh down to where you want the shorts to end—typically just above the knee for most BJJ and MMA-style shorts. Shorts that run too long can interfere with knee mobility, while shorts that are too short may ride up during rolling.

Account For Stretch Fabric And Fit Preference

Most BJJ shorts are made from polyester and spandex blends specifically because they offer four-way stretch, so the "true to size" measurement isn't the whole picture.

Some athletes prefer a slightly closer fit for competition, while others prefer a bit more room for daily training. When measurements fall between two sizes, consider:

• Whether the shorts will mainly be used for training or competition

• Personal preference for a snugger vs. relaxed fit

• The specific fabric blend, since stretch percentage varies by material

Compare With The Brand's Size Chart

Sizing can vary noticeably between manufacturers, so the same waist and hip measurements might translate to different sizes depending on the brand.

Always check the specific size chart provided for the exact product—such as MMA BJJ Short Supplier styles—rather than assuming standard S/M/L sizing will match across different shorts.

Consider Customization For Team And Bulk Orders

For gyms, teams, and brands ordering in bulk, measurement consistency becomes even more important since sizing needs to work across a wide range of body types.

Working with a supplier that offers custom sizing options—alongside custom colors, logo placement, and sublimation printing—makes it easier to build a size range that actually fits your athletes, rather than relying on generic size charts alone.

Select A Reliable BJJ Shorts Supplier

For businesses developing their own BJJ or MMA apparel line, choosing a supplier that understands grappling-specific fit is just as important as fabric quality.

A professional manufacturer should be able to provide sizing guidance, offer sample fittings, and support custom size grading for team or retail orders—helping avoid costly sizing mistakes across a full production run.

Final Thoughts

Getting the right fit for BJJ shorts comes down to measuring the waist, hips, and inseam accurately, then checking those numbers against the specific brand's size chart rather than standard clothing sizes. With the right measurements and a supplier who understands grappling apparel, both individual athletes and teams can avoid sizing issues and get shorts that perform well on the mat.
