BJJ weight classes explained: how to read an event chart

Why there is no universal chart

A division name alone is not enough to identify its weight limit. ADCC and the IBJJF are separate organisations with separate documents, and inside each of them the figures depend on the category you are entering.

There is a second layer underneath that, which is the event. An organisation's general chart tells you how it structures divisions; the event you are entering publishes the chart that actually applies, and it may differ in the unit it measures, in which divisions are being run at all, and in whether classes have been merged to make workable brackets.

So the question is never what the weight classes are. It is what this event's chart says, and the only reliable answer is the one the organiser published for that event.

How to read a chart, in order

Find the event's own chart first, on the event page rather than from a third party, and note its revision date. These documents get revised: the ADCC division chart used below is marked as revised on 31 October 2026, which identifies the specific revision used in this guide. Check the event for later revisions.

Find your category. Charts are divided by age first, and the names are not self-explanatory: a category called adult may carry an age range, and masters categories are numbered rather than described.

Find your sex, since male and female charts carry different figures and are usually printed as separate columns or blocks.

Find your weight label, and read it as the chart writes it. The ADCC chart writes each class with a minus sign and a stated maximum, and the heaviest class with a plus sign to mean everything above the one below it. Do not translate a label into a range the document does not print.

Then read the two practical notes that decide whether you are actually in that division: the unit the event measures in, and what you wear on the scale. Both are covered below, and both have ended people's days.

A worked example: the ADCC Opens adult classes

These are the adult classes on page 2 of the ADCC weight classes, divisions and categories chart revised 31 October 2026, as published for its Opens events. They are an example of how one organisation's chart reads. They are not IBJJF figures, they are not ADCC World Championship categories, and they should not be carried to another event.

Male adult and masters classes are labelled, in kilograms: -55, -60, -65, -70, -76, -83, -91, -100 and +100.

Female adult and masters classes are labelled, in kilograms: -50, -55, -60, -65, -70, -75, -80 and +80.

The chart prints a maximum alongside each kilogram label, including a pound figure, so read the maximum on the chart itself rather than converting a label yourself. The heaviest class is an open-ended weight class above the preceding label; it is not the separate absolute division.

Two structural notes from the same document. The organiser reserves the right to combine weight classes when necessary to create competitive brackets, so a class on the chart is not a guarantee that the class will run as printed. And all adult, female adult and masters competitors are required to weigh in before competing, with valid identification or a passport presented at the weigh-in.

IBJJF no-gi adult and master weight classes in pounds

This is the undated official chart linked from the IBJJF No-Gi World Championship 2026 event, checked on 3 November 2026. These are maximum pounds for adult and master athletes wearing the no-gi uniform. Juvenile columns are deliberately excluded.

No maximum means an open-ended weight class. Open class (absolute) is separate from the rows below; read the event rules for eligibility. No female ultra-heavy division is shown in this chart.

Categories, and the age question you should not take from a guide

Age categories are where charts most often disagree with other pages about them, including, sometimes, with their own organisation's other pages.

On the ADCC division chart revised 31 October 2026, the adult category carries an age range and the masters categories are numbered upward from Masters 1, whose age band the chart states as 30 and over. The ADCC rules landing page describes a first masters band of 35 and over. We are not resolving that disagreement by picking one, because neither is ours to pick: check the chart published for the event you are entering, and if it is still ambiguous, ask the organiser in writing before you register.

The same chart also states that masters competitors may register downward toward the adult category but that adult or masters competitors may not register upward, and it covers kids, teens and masters categories which this guide does not reproduce. Read the chart for your own category rather than a summary of it.

Skill level is a separate axis from age and weight. Divisions are commonly split by experience as well, and which splits an event runs is in its own documents.

What an absolute division is, and is not

An absolute division is not another weight class. It is a separate category in which competitors from different weight classes enter the same bracket, which is why it tends to be the one spectators remember.

On the ADCC chart revised 31 October 2026, absolute divisions are offered exclusively in the adult category, masters competitors who want to enter one must register for and compete in the adult absolute division, and all absolute competitors must be 18 or over, with exceptions only by prior approval from the organiser. The organiser also reserves final decisions on division mergers, competitor eligibility and absolute participation.

So the absolute is a parallel entry rather than a heavier class, and eligibility for it belongs to the organiser rather than to the chart. If you are reading an absolute bracket and wondering why someone two classes lighter is in it, that is the design working as intended.

Uniform and units: the two things that disqualify people

The IBJJF's published weigh-in page is explicit about what you wear, and it differs by format. In a gi tournament the athlete checks their weight with the gi on, and the page states that all athletes should fight and weigh in with the gi. In a no-gi tournament the athlete checks their weight in the no-gi uniform, and again fights and weighs in wearing it. That is why a figure measured at home in shorts is not the figure that matters.

The same page states there is only one opportunity to check the weight, that a competitor who does not make their weight is immediately disqualified, and that divisions cannot be changed on the day. It also directs athletes to the tournament's own important information for the official weight measurement used at that event.

That last point is the units trap. Measurement is an event-level fact, not an organisation-level one: the IBJJF's No-Gi World Championship 2026 event page states its weights in pounds, while the ADCC chart above is written in kilograms with a stated maximum beside each label. Converting the wrong way round, or comparing a pound figure with a kilogram label, is an avoidable way to enter the wrong division.

The table above reproduces only the adult/master columns of the official event-linked no-gi pounds chart checked on 3 November 2026. The chart itself has no edition date; its link from the 2026 event does not make it a new rulebook edition. Do not use these figures for juvenile or gi divisions.

Nothing on this page is advice about changing your body weight for an event. It explains how a chart is organised and what the weigh-in rules say; it is not diet, hydration or medical guidance, and questions about preparing for a weigh-in belong with your own coach and, where relevant, a qualified professional.

If you train here rather than compete

Weight classes organise competition brackets. Ask the coach how partners are selected in a class; do not infer a pairing policy from a competition chart.

Every class at this academy is no-gi Brazilian Jiu-Jitsu and submission grappling, so the format is the one the no-gi charts above govern. If you decide to enter an event, its own chart and its own weigh-in rules are the documents to read. This article explains competition categories rather than a service or preparation plan.

If you have not trained before, none of the above is a prerequisite for anything. A one-off trial class is $30, requested in advance and confirmed by the academy. Tell the academy your experience and ask what to expect before attending.

Choose an hour and ask for it on the $30 trial session chooser, or read what the no-gi format involves first. Classes are booked ahead, so wait for the academy's confirmation.
