If you’ve ever wondered how Jiu Jitsu athletes get paired up in competitions, the answer is simple—weight classes. These classes make sure everyone competes on a fair playing field, but there’s more to it than just stepping on a scale.
Knowing the right weight class can improve your strategy, performance, and even your overall experience in the sport.
Let’s dive into the world of weight classes in Jiu Jitsu and why they’re essential for both beginners and seasoned practitioners.
What Are Weight Classes in Jiu Jitsu?
Weight classes are a core part of any Jiu Jitsu competition. They exist to make sure athletes of similar size are paired against each other, keeping things fair and competitive.
If you’ve ever grappled with someone much heavier or much lighter than you, you know that size can make a huge difference in how a match plays out.
This is why weight classes are critical—they level the playing field so skill, not just size, determines the winner.
Each major Jiu Jitsu organization, like the IBJJF (International Brazilian Jiu Jitsu Federation), has its own set of weight divisions. Though they may differ slightly, the idea remains the same across the board: keeping fights balanced.
Whether you’re a roosterweight or an ultra-heavyweight, your weight class gives you the chance to compete against others in your size range, so you can focus on your technique.
Breakdown of Adult Male Weight Classes
Jiu Jitsu weight classes for men span a wide range. Here’s a look at the most common divisions and what you can expect when competing in each one.
Roosterweight (Lightest Division)
Roosterweight is the lightest weight class, typically under 126 lbs (or around 57 kg). Competitors in this division are often very quick and rely on speed and technique to outmaneuver their opponents.
Because there’s less mass involved, these athletes often have a dynamic style of play, with a focus on agility rather than brute strength.
Middleweight
Middleweight competitors fall around the 181 lbs (82 kg) range. This is often considered a balanced class where you’ll see athletes who have a mix of speed and power.
Middleweights can adapt their game to focus on technique, strength, or endurance, depending on their style and strategy. You’ll find this division is full of some of the most versatile fighters.
Ultra-Heavyweight (Heaviest Division)
On the opposite end, ultra-heavyweights weigh over 221 lbs (100 kg). In this class, strength often plays a significant role.
Competitors here tend to focus on using their weight to control and dominate opponents, and matches might not be as fast-paced as in lighter divisions.
However, technique still matters a great deal—knowing how to use your weight effectively can make all the difference.
Breakdown of Adult Female Weight Classes
Women’s Jiu Jitsu weight classes share similarities with the men’s, but with weight limits that reflect the average body types for female athletes. Understanding these classes is crucial if you want to optimize your competition strategy.
Roosterweight to Featherweight
These lighter classes (typically up to 141 lbs or 64 kg) feature some of the most agile and technical athletes.
Women in these divisions often rely on quick transitions, positional dominance, and submission attempts that take advantage of their speed and flexibility.
Middleweight and Medium-Heavy
For women weighing in around 152 lbs (69 kg), these divisions bring a blend of technique and physicality.
It’s a sweet spot for many competitors who like to combine their athleticism with smart, strategic play. Here, you’ll see a good balance between agility and strength.
Super-Heavy and Above
Super-heavyweight and above (over 175 lbs or 79 kg) divisions bring some serious power to the mat. In these weight classes, athletes can use their mass to control their opponent and dictate the pace of the match.
However, don’t let size fool you—many competitors in this division also have excellent technique and use it to outmaneuver their opponents.
How Weight Classes Impact Competitors’ Strategy
Choosing the right weight class is more than just stepping on a scale. Your choice can significantly impact your game plan, how you train, and even your overall success in competitions.
Weight Cutting vs. Walking Weight
A common strategy in Jiu Jitsu is weight cutting—dropping pounds before weigh-ins to compete in a lower class.
However, this comes with risks. Some athletes prefer to compete at their “walking weight,” which is the weight they naturally sit at without extreme dieting or dehydration.
Cutting too much weight can sap your energy, so it’s important to strike a balance. If you’re cutting, do it smartly—otherwise, it might hurt more than help.
Choosing the Right Division
It’s essential to know your body and understand where you’ll perform best. Are you comfortable with a little extra mass, or do you feel faster and more effective in a lighter division?
Experimenting with different weight classes in local competitions can help you figure out which weight is ideal for you. Keep in mind that some athletes feel stronger and more capable when they aren’t draining themselves to make weight.
Training Adjustments for Different Classes
Depending on your weight class, you’ll need to adjust your training.
Lighter athletes might focus on agility drills, speed, and endurance, while heavier competitors should work on strength, balance, and using their weight effectively.
No matter the class, it’s important to train in a way that maximizes your natural abilities.
Youth and Master Divisions: Weight Classes for Non-Adult Competitors
It’s not just adults who have weight classes—youth and masters (older competitors) divisions follow the same principles, with a few adjustments based on age and experience.
Youth Weight Classes
For younger competitors, weight classes help ensure that matches are safe and fair. These divisions are especially important because children are still developing, and big weight differences could lead to unfair or even dangerous matches.
Youth divisions allow kids to learn and grow in the sport while competing against others of similar size.
Master Divisions
As athletes age, the master divisions come into play. These are for older competitors, typically starting at age 30, with several different categories based on age brackets.
Weight classes in master divisions follow the same guidelines as adult classes, but with more emphasis on longevity and safety.
Competing in the right weight class here can help older athletes avoid injury and continue to enjoy the sport for years to come.
Common Challenges for Youth and Masters
Youth athletes often face the challenge of growing between competitions, which means they may move up in weight classes more frequently than adults.
On the other hand, masters athletes may find that their bodies change with age, making weight management more difficult. In both cases, it’s important to stay flexible and adapt to these changes.
How to Prepare for Weigh-Ins and Competitions
Proper preparation can make or break your competition experience. From managing your weight to fueling your body, here’s what you need to know to step on the mat ready to perform.
Weigh-In Rules for Major Competitions
Each organization has its own rules for weigh-ins, so always check the guidelines for your event.
Typically, you’ll weigh in either just before or the day before your match. It’s essential to know when your weigh-in will be, as this affects how you manage your weight in the days leading up to the competition.
Healthy Weight Cutting Methods
If you’re cutting weight, do it safely. Avoid extreme dehydration or crash diets, as these can leave you feeling weak and sluggish on competition day.
Instead, focus on a gradual reduction in calories and water intake while maintaining proper nutrition. The goal is to cut fat, not muscle or water weight.
Staying Hydrated and Strong
Hydration is key, especially if you’re cutting weight. Make sure you’re drinking enough water throughout your training and leading up to the competition.
After weigh-ins, rehydrate and refuel with healthy carbs and protein to give your body the energy it needs to perform.

FAQs
How many weight classes are there in jiu-jitsu?
There are typically 9 or 10 weight classes in Jiu-Jitsu, depending on the organization and whether it’s for men or women. These range from the lightest, like roosterweight, to the heaviest, like ultra-heavyweight. The exact weight ranges vary slightly between competitions, but the idea is always to match you up with someone of a similar size for fair competition.
What weight should I be for BJJ?
There’s no perfect weight for Brazilian Jiu Jitsu—it really depends on where you feel the strongest and most comfortable. Some people compete at their natural “walking” weight, while others prefer to cut a little weight to get into a lighter class. Ultimately, you want to be in a class where you feel fit, strong, and not drained from cutting too much.
Do BJJ tournaments have weight classes?
Yes, BJJ weight classes exist in tournaments. This helps make matches fair by pairing competitors of similar sizes. Weight classes can vary slightly depending on the organization (although most use the IBJJF weight classes), but you’ll always weigh in before your match to ensure you’re in the right division. It keeps things competitive and ensures skill, not just size, wins the day.
What is featherweight in jiu-jitsu?
Featherweight in Jiu-Jitsu usually refers to competitors who weigh around 149 lbs (67.5 kg) for men, depending on the organization. It’s a division where you’ll see a good balance between speed and strength, making for exciting matches. If you’re competing in this class, expect to use both agility and technique to gain the upper hand.
Is 3 times a week Jiu-Jitsu enough?
Yes, training Jiu-Jitsu three times a week is definitely enough to see progress. It gives you a good balance of practice and recovery, especially if you’re just starting out or have other commitments. Consistency is key, so sticking to that schedule will help you build muscle memory and improve your technique without overdoing it.
Will jiu-jitsu give you abs?
Jiu-Jitsu can definitely help you build strong abs, but it won’t magically give you a six-pack on its own. The sport works your core constantly, especially during grappling and transitions, which is great for developing core strength. Pair it with a good diet and some additional cardio, and you’ll see those abs coming through over time.
