International Brazilian Jiu-Jitsu Federation

The International Brazilian Jiu-Jitsu Federation (IBJJF) is the largest and most prestigious Brazilian Jiu-Jitsu organization in the world. Founded by Carlos Gracie Jr., the IBJJF sets the standard for BJJ competition rules, belt requirements, and tournament operations globally.

The IBJJF hosts the sport's most recognized events, including the World Jiu-Jitsu Championship (Mundials), Pan Jiu-Jitsu Championship, European Open, and Brazilian Nationals. These tournaments attract thousands of competitors from dozens of countries each year.

For youth competitors, the IBJJF provides a structured competitive pathway from the youngest age divisions through Juvenile and into the adult ranks. The organization's rule set is the most widely adopted in BJJ, making IBJJF tournaments an excellent benchmark for measuring progress.

IBJJF tournaments are known for their strict adherence to rules, professional refereeing standards, and well-organized bracket systems. Many academies consider IBJJF competition the gold standard for testing their students' development.

The IBJJF uses a position-based scoring system where points are awarded for achieving and holding dominant positions for 3 seconds. This stabilization requirement ensures competitors demonstrate real control, not just transitional movement.

Key scoring rules: - Points are only awarded once per position per sequence — you cannot repeatedly score the same position without your opponent first recovering guard or escaping - A sweep must start from guard position; reversals from other positions do not score sweep points - Back control requires both hooks (or a body triangle) to score - Mount includes both standard mount and S-mount positions

For a deeper breakdown of scoring across organizations, see our scoring guide.

The IBJJF offers extensive youth divisions organized by age group and belt rank. Youth competitors wear colored belts specific to their age category, which differ from the adult belt system.

Youth Age Divisions:

Youth Belt System: Youth competitors (under 16) use a separate belt progression: White, Grey, Yellow, Orange, and Green belts, each with solid and striped variations. At age 16, competitors transition to the adult belt system starting at White or Blue belt depending on their rank and instructor evaluation.

Important for parents: Age is determined by the competitor's age on the day of the tournament. Competitors always compete in the age division matching their current age, regardless of when they registered.

For more on the youth belt system, see our guide on understanding youth BJJ belts.

Match duration in IBJJF tournaments varies by age division and belt rank. Higher belts and older competitors receive longer matches to allow for more technical exchanges.

Adult Match Times:

Youth Match Times: Youth matches are generally shorter to account for the age of competitors: - Mighty Mite through Junior: 2–3 minutes - Teen: 4 minutes - Juvenile 1 & 2: 5 minutes

Finals adjustments: In some major IBJJF events, finals matches may receive additional time. Black belt finals at Worlds and Pans can be extended.

Overtime: The IBJJF does not use a traditional overtime system. If a match is tied on points and advantages, the referee decides the winner based on which competitor was more aggressive and dominant throughout the match. This "referee decision" mechanism is one reason competitors are strongly encouraged to actively pursue scoring positions rather than playing defensively.

The IBJJF restricts certain techniques based on age and belt level to protect competitor safety. As competitors advance in rank, more techniques become available.

Submissions restricted at White Belt (adult): - No heel hooks (inside or outside) - No knee reaping - No bicep slicers or calf slicers - No wrist locks - No cervical neck cranks

Submissions allowed at Brown/Black Belt: - Calf slicers - Wrist locks - Knee reaping (in no-gi, recent rule updates) - Toe holds

Techniques banned at ALL levels: - Slam from guard (lifting and dropping an opponent) - Suplex throws - Scissor takedowns (kani basami) - Neck cranks (without a choke) - Spinal locks without choke

Youth restrictions: Youth divisions have the most protective rules. Chokes using the lapel are generally limited to older youth divisions, and leg attacks are heavily restricted. Children's divisions prohibit most leg submissions.

Important: The IBJJF periodically updates its rule set. Always check the current rules on the IBJJF website before competing. Rule changes are typically announced well in advance of taking effect.

Registering for an IBJJF tournament requires several steps. Plan ahead — registration windows fill up, especially for major events.

Registration steps: 1. Create an IBJJF account at ibjjf.com 2. Purchase an annual membership — required for all competitors 3. Verify your academy affiliation — your instructor must be registered with the IBJJF 4. Register for a specific tournament during its open registration window 5. Pay the tournament registration fee (separate from membership) 6. Complete any required documentation — minors need parental consent forms

Membership details: - Annual membership is required and must be active at the time of competition - Membership includes athlete registration, belt verification, and access to the IBJJF ranking system - Membership fees vary by region

Registration tips for parents: - Register early — popular divisions fill up quickly - Double-check your child's age division and weight class before registering - Ensure your child's belt rank is correctly recorded in the IBJJF system - Keep a copy of all registration confirmations and receipts - Bring a valid photo ID for the competitor (and parent/guardian for minors) on tournament day

IBJJF weight classes vary by gender, age division, and whether the competition is gi or no-gi. In gi divisions, the weigh-in includes the weight of the gi.

Adult Male Gi Weight Classes:

No-gi weight classes are slightly lighter since competitors are not wearing a gi (approximately 0.5–1 kg lighter thresholds).

Youth weight classes are organized differently with more granular divisions to ensure fair matchups among growing children. Weight classes get progressively broader as age increases.

Weigh-in rules: - Weigh-ins occur on the day of competition, typically in the morning - Competitors weigh in wearing their gi (for gi divisions) or competition shorts/rash guard (for no-gi) - There is no allowance period — you must make weight at the time of weigh-in - Competitors who miss weight cannot compete in their registered division

The IBJJF establishes minimum age and time-in-rank requirements for belt promotions. These are minimums — actual promotion timing depends on the individual's instructor assessment.

Adult Belt Minimum Requirements:

Youth Belt Progression: Youth belts (Grey, Yellow, Orange, Green) have their own age requirements. When a youth competitor reaches 16, they may be promoted to Blue belt by their instructor if their skill level warrants it.

Stripe system: Each belt level includes 4 stripes that instructors award to mark progress. Stripes are at the instructor's discretion and are not regulated by minimum time requirements.

Important notes: - Promotions must be registered with the IBJJF for competition purposes - Only instructors registered with the IBJJF can promote competitors who wish to compete in IBJJF events - Belt verification may be checked at tournament registration - Sandbagging (competing at a belt below your skill level) can result in forced promotion or disqualification

IBJJF tournaments use a single-elimination bracket format. This means a competitor is eliminated after their first loss.

Bracket structure: - Single elimination with a consolation round for bronze - Competitors who lose to a finalist compete in a repechage (bronze medal match) - This means there are two bronze medals awarded in each division - If a division has only 2 competitors, it is a single match for gold and silver - If a division has only 3 competitors, a round-robin format may be used

Absolute division: In addition to weight-class divisions, many IBJJF tournaments offer an Absolute (open weight) division where competitors of any weight can enter. This is optional and separate from the weight-class bracket.

Seeding: At major IBJJF events, top-ranked athletes may be seeded to avoid early-round matchups. Seeding is based on the IBJJF ranking system, which tracks points earned at previous IBJJF tournaments.

Match flow: 1. Competitors are called to their assigned mat area 2. Both competitors must present themselves in proper attire 3. The referee starts the match from standing position 4. Points, advantages, and penalties are tracked on the scoreboard 5. Match ends by submission, points, advantages, penalties, or referee decision

The IBJJF has specific rules about gi construction, fit, and color for competition. Non-compliant gis will fail inspection and the competitor will not be allowed to compete until they change into a compliant gi.

Allowed gi colors: - White, Blue, or Black — the entire gi must be one of these colors - The top and bottom must be the same color - Small brand patches and academy logos are permitted within size limits

Gi fit requirements: - Sleeve length: Must reach no more than 5 cm above the wrist bone when arms are extended - Pant length: Must reach no more than 5 cm above the ankle bone - Lapel thickness: The lapel must be thick enough that an opponent can grip it - No excessively tight or slippery gis — the gi must allow for normal gripping

Gi inspection: - Gis are inspected before the competitor's first match - Referees use a measuring device to check sleeve and pant openings - If a gi fails inspection, the competitor typically has a short window to change

No-gi attire: For no-gi divisions, competitors must wear a rash guard (short or long sleeve) and board shorts or spats without pockets, zippers, or buttons. Rash guards must be form-fitting. The IBJJF specifies color requirements for no-gi attire at certain events.

Tip for parents: Bring a backup gi to every tournament. Gis can fail inspection, get torn during a match, or become too soiled to continue.

Knowing what to expect on tournament day reduces stress for both competitors and their families. Here is a typical IBJJF tournament day timeline.

Before arriving: - Confirm your division, mat assignment, and estimated start time on the IBJJF website or app - Pack your gi (plus a backup), water, snacks, sandals, and any required documents - Arrive at least 1 hour before your scheduled division time

At the venue: 1. Check in at the registration desk with your ID and proof of registration 2. Weigh in — this happens early in the day; do not miss your weigh-in window 3. Gi inspection — have your gi checked before your first match 4. Wait for your division call — listen for your name and mat number on the PA system 5. Warm up in the designated warm-up area (not on competition mats)

During matches: - Coaches are permitted in the designated coaching area beside the mat - Only one coach per competitor is typically allowed matside - The head referee's decisions are final on the mat - Protests can be filed after the match through official IBJJF procedures

After competing: - Medal ceremonies are held after all matches in your division are complete - Results are posted on the IBJJF website and tracked on JITS.GG for supported events - Collect any belongings from the warm-up area before leaving
