“Light” looks like a complete answer until the format changes. In the official Adult men’s references below, Light has a maximum of 76.00 kg in gi and 73.50 kg in no-gi. The category name stayed the same. The limit did not.
That gives the lookup a useful order: identify the organizer, age category, format, chart column, and unit before reading across the row. Reversing that order can produce a familiar number from the wrong table. The explorer lets you focus one Adult reference, while all four complete charts remain available below it.
The kilogram and pound values come from separate official PDFs linked by current IBJJF event pages. They are published limits, not calculated conversions. This guide explains how to read them and how the table relates to an entry; the first-tournament guide covers the wider registration and match-day process.

Sources checked October 22, 2026. Decimal commas in the kilogram PDFs are displayed as decimal points; the values and precision are preserved. Pound values retain the precision printed in their sources. Open Class is separate from the top uncapped weight category. An Adult chart reference does not establish eligibility or select an athlete’s division.
Read the number with its conditions
The complete numeric Adult charts are in the explorer. Keep these distinctions beside the actual event’s Weight Chart link.
On a small screen, scroll across the table to read every column.
| Detail | What it means | What to check |
|---|---|---|
| Organizer and event | A federation reference is not every promoter’s weight system. | The current chart linked by the competition you entered. |
| Adult category and format | Men’s and women’s, gi and no-gi have separate columns and limits. | The complete division description, rather than a category name alone. |
| Maximum weight | The capped number is a ceiling, not an exact target or a body description. | The published limit in the event’s official unit. |
| Official unit | Kg and lb columns reproduce separately published charts. | Use the organizer’s stated unit rather than your own conversion. |
| Uniform and procedure | IBJJF includes the appropriate competition uniform in the weighing requirement. | Required kit, weighing time, and the event’s procedure. |
| No maximum weight | The named top weight category has no printed ceiling. | Keep it separate from Open Class and its eligibility conditions. |
| Actual entry | Reading a row and registering in that row are different steps. | Check the accepted entry and any available correction process. |
These are IBJJF Adult references checked October 22, 2026. A chart lookup does not approve a division entry.
Give the chart an address
A weight-class label needs context. “IBJJF Adult women’s gi, kilograms” identifies a reference; “Feather” by itself does not. The same category name can appear under different age groups, formats, and organizers. Begin with the full description and keep it attached to the number you copy.
The four references here use the Adult men’s and women’s columns in official IBJJF gi and no-gi charts. Some PDF headers group Adult and Masters together. We have extracted the Adult reference, rather than turning that shared column into advice about which age division someone may enter. The entered event still needs to offer your actual age and belt category.
IBJJF’s championship help page directs athletes to the weight chart on the specific event page and says divisions can vary between events. That instruction matters even when a general table looks familiar. Find the Weight Chart link for the competition, then check the heading, format, column, and unit.
A saved chart can remain useful after the original event has finished, but its source should remain visible. The explorer identifies the event pages from which these official PDFs were checked. When you move from reference reading to registration, open the current event’s own link. That gives you the document the organizer has attached to that entry.
Read a maximum as a ceiling, not an exact target
The capped rows in these official charts are headed maximum weight. The printed number is the highest permitted measurement for that row, not a weight every entrant must equal. IBJJF’s help page explicitly says a competitor may weigh below the division’s listed limit, while weighing above it results in disqualification.
For example, the Adult men’s gi Middle row lists 82.30 kg in the kilogram source. The table does not say everyone in that division weighs exactly 82.30 kg. Nor does the row name describe an athlete’s reach, strength, experience, or likely result. It identifies the category and its maximum under the stated chart.
Read shorthand against that definition. An event or result may abbreviate a category with a number, but the official chart tells you whether you are looking at a maximum, a unit, or a different category altogether. Avoid copying a standalone number into another form without checking the full row label beside it.
A useful observation task is to locate the category, trace horizontally to the correct Adult column, and then read the unit. Repeat it from the heading rather than starting from memory. This catches a common table-reading mistake: finding the right row and then taking the adjacent Juvenile value instead of the Adult value.
Gi and no-gi keep the names but change the limits
The Adult men’s gi and no-gi charts both run through Rooster, Light Feather, Feather, Light, Middle, Medium Heavy, Heavy, Super Heavy, and Ultra Heavy. Shared labels make the two tables easy to compare. They do not make the numbers interchangeable.
Look at two pairs in the kilogram sources. Adult men’s Rooster is 57.50 kg in gi and 55.50 kg in no-gi. Adult men’s Light is 76.00 kg in gi and 73.50 kg in no-gi. Those pairs have different gaps. A rule such as “subtract the same amount from every gi category” would fail even within this short comparison.
Use the no-gi chart directly when reading a no-gi entry. There is no need to reconstruct its limits from the gi list or estimate how a jacket changes a category. The published rows already provide the reference. The same approach applies when checking the pound charts: use the no-gi pound value printed by the source.
If you enter both formats, keep two complete category descriptions with the registration details. The relevant comparison is the entered gi row against the gi chart and the entered no-gi row against the no-gi chart. Our gi versus no-gi guide explains the clothing and grip differences; this page keeps the weight references distinct.
The men’s and women’s columns are separate references
In the charts used here, the Adult women’s list has eight named weight categories, ending at Super Heavy. The Adult men’s list has nine, ending at Ultra Heavy. The women’s cell in the Ultra Heavy row is blank in the source. That blank is not a missing limit to fill from the men’s column.
The shared names also have different caps. Adult women’s gi Heavy is 79.30 kg; Adult men’s gi Heavy is 94.30 kg. In no-gi, the corresponding Heavy maxima are 76.50 kg and 91.50 kg. These are four chart entries with their own context, rather than one definition of the word Heavy.
Use the labels printed in the event’s division list and the appropriate chart column together. A table described only as “Adult weights” is incomplete if it leaves out which category and format the numbers belong to. The explorer names each combination above its table so the reference stays visible while you read.
This is also why we do not extend the Adult rows into a children’s lookup. The original PDFs contain other age columns, and the no-gi source distinguishes Juvenile categories within its layout. Those columns deserve their own accurate reading. For a younger entrant, start with the event’s age and division information instead of treating an Adult number as a general BJJ limit.
Use the published unit instead of building a conversion table
The official gi kilogram and pound charts do not require you to calculate one from the other. They each publish limits. In the sources checked here, Adult men’s gi Light is 76.00 kg in the kilogram chart and 168.0 lb in the pound chart. Both values are reproduced as published; the pound column has not been generated by a conversion formula.
Preserving that distinction avoids adding a new rounding rule. Converting a number on a phone and rounding it yourself can produce a figure that is not the limit printed in the organizer’s chart. When the actual event specifies pounds, use its pound chart. When it specifies kilograms, use its kilogram chart.
The event page supplies that choice. Waco International Open 2026 states that its official measurement is pounds; European No-Gi 2026 states kilograms. Those are concrete event examples checked October 22, 2026, rather than a rule that every country or promoter uses one unit.
For readability, the kilogram PDFs’ decimal commas appear here as decimal points: 76,00 becomes 76.00. That changes the notation, not the value. The pound cells retain the precision shown by their source, including values such as 122.6. Keep the unit beside the number when saving a category; a bare 76 is an incomplete record.
The required uniform belongs in the measurement
IBJJF’s weigh-in instructions say gi competitors weigh in with the gi and no-gi competitors with the no-gi uniform. No-gi removes the gi from the format; it does not make the official measurement a clothing-free number. Read the chart and the weighing instructions as parts of the same requirement.
The instruction also describes weighing before the first match, a single opportunity, and disqualification if the entered limit is exceeded. It says competitors cannot simply change divisions on the day after failing to make the registered category. Those consequences explain why an approximate recollection of a chart is less useful than the actual source attached to the event.
Use the uniform specified for the competition when checking what the requirement means for your entry. Ask the organizer about an unclear procedure before the day. The chart does not supply a standard weight for every gi, rashguard, or pair of shorts, and the difference between two category limits is not a measurement of a particular uniform.
The gi-size guide covers manufacturer sizing and fit, while the clothing guide separates class kit from competition requirements. Uniform size and competition weight class answer different questions. A size label such as A2 is not a weight-division registration.
An uncapped category is separate from Open Class
At the top of the Adult men’s references, Ultra Heavy says No maximum weight. At the top of the women’s references, Super Heavy uses the same wording. We preserve that phrase instead of inventing a numeric ceiling. Each sits after the largest capped category in its column.
The source does not print a new mandatory minimum for those uncapped cells. Describing their place in the ordered list is different from claiming the chart requires a specific lower boundary. Keep the published maximum rule separate from an assumption about how much every athlete in the category must weigh.
Open Class appears in its own row on the official PDFs. The Adult cells read Free/Livre, separate from the named weight categories above them. Open Class is not another name for Ultra Heavy or women’s Super Heavy. Its entry conditions come from the actual event; an uncapped weight-category cell does not grant admission to that bracket.
The Waco 2026 gi page makes the distinction visible: it lists Open Class entry conditions and says its white-belt gi divisions have no Open Class. Read the actual event’s conditions if an absolute or Open Class bracket interests you. Its availability, registration, and age or belt requirements are questions beyond the uncapped cell in a weight chart.
Match the row to the entry before the correction window closes
Put five details together before treating the lookup as complete: the event, format, age and category, named weight class, and official unit with its published limit. Check those details against the actual registration. A correctly read chart cannot correct a different category selected in the entry form.
If the chart and registration appear to conflict, keep both open and ask the organizer a specific question. Identify the event, the complete category label, and the source you are reading. Ask which official unit and limit govern that division. This is easier to resolve than sending only a screenshot of an isolated row.
Use the stated correction process while it remains available, and verify any accepted change in the official entry. IBJJF’s help pages direct athletes to event-specific correction dates. The first BJJ tournament guide explains how to distinguish athlete corrections, later stages, and live reporting without turning this reference into another registration checklist.
The final check is a short one: does the entered row match the chart you meant to use? If the answer depends on a conversion, a guessed clothing allowance, or a category name borrowed from another format, return to the heading. Reading the correct number starts with locating the correct table.
Common questions
What are the IBJJF Adult BJJ weight classes?
In the official references here, Adult men’s categories run from Rooster through Ultra Heavy; women’s run from Rooster through Super Heavy. Gi and no-gi use different limits. Choose the format and category in the explorer to read the complete published kilogram and pound references, then confirm the chart linked by your event.
Do IBJJF weight limits include the gi?
For gi competition, IBJJF says athletes weigh with the gi on. No-gi athletes weigh with the required no-gi uniform. The chart therefore belongs with the event’s weighing and clothing instructions. Do not apply an assumed clothing allowance or treat the no-gi limit as a clothing-free measurement.
Are gi and no-gi weight classes the same?
Their names can match while their limits differ. Adult men’s Rooster is 57.50 kg in the gi source and 55.50 kg in the no-gi source checked here. Use each format’s own chart rather than subtracting a fixed amount from the gi values or carrying a gi registration label into no-gi without checking.
Can an IBJJF competitor weigh less than the class limit?
IBJJF’s championship help page says weighing below the listed maximum does not itself disqualify a competitor. The number is a ceiling, not an exact required measurement. Other eligibility and entry conditions still apply. This reference explains that published rule; it does not select a personal weight class.
Should I convert kilograms to pounds for my event?
Use the official unit and chart specified by the event. The pound limits shown here are transcribed from official pound charts, not calculated from kilograms. A personal conversion and rounding choice need not match the published limit. Keep the event’s stated unit with the category you record.
Is Ultra Heavy the same as the absolute or Open Class?
No. Ultra Heavy is the top uncapped Adult men’s weight category in these references; women’s Super Heavy is also uncapped. Open Class is a separate row with its own event conditions. An uncapped weight-category cell does not establish Open Class eligibility or registration.
Can I use these Adult charts for a child or Juvenile entrant?
Use the chart and age column specified for that entrant’s event. This page extracts Adult references only. The official source PDFs contain separate Juvenile columns, and children’s divisions require their own information. A shared weight-class name does not make the Adult limit transferable to another age group.
