Boxing Glove Rules Explained: IBA, World Boxing, WBC and Pro Commissions (2026 Guide)

Last updated: 6 October 2026

Ask five people at a boxing gym what gloves you need for a fight and you might get five answers. Someone says 10 oz, someone says 8 oz, someone tells you that your own gloves are fine, and someone else says you will be handed gloves on the night anyway.

The reason is simple. Boxing has no single rulebook. Amateur boxing, Olympic style boxing and professional boxing each have their own rules, and in the pro game the local commission often has the final word. This guide breaks it down so you know exactly what applies to your next bout.

Amateur boxers usually fight in 10 oz or 12 oz gloves, depending on weight and category, and the gloves must be approved by the governing body. Professional boxers usually fight in 8 oz gloves up to welterweight and 10 oz gloves from super welterweight and up.

For years, international amateur boxing was run by the IBA (formerly AIBA). After a long dispute with the International Olympic Committee, a new federation called World Boxing was created, and it now runs boxing for the Olympic movement. Many national federations have moved over to World Boxing, while some still compete under IBA. That is part of why you will see both names on competition gloves.

The glove rules in both are quite similar. Under World Boxing, the weight depends on age, sex and weight category: women and U17 men wear 10 oz gloves in every category, while Elite and U19 men wear 10 oz up to 65 kg and 12 oz above that. National federations then adapt this. Boxing Canada, for example, follows the World Boxing rules with its own changes, using 10 oz for male categories 50 to 65 kg, 12 oz from 70 kg up, 10 oz for all women, and 16 oz for masters, with gloves required to be World Boxing or USA Boxing approved. fightgearboxingcanada

England Boxing sets its cutoff a little differently. Boxers at 67 kg and under wear 10 oz gloves, those over 67 kg wear 12 oz, and if one boxer is under and the other over the limit, both wear 12 oz. englandboxing

A few things are almost universal in amateur boxing:

So for amateur boxers, your own competition gloves are mostly useful for training in the same feel as fight night, and for club shows where you are asked to bring approved gloves.

The WBC, WBA, IBF and WBO are sanctioning bodies. They rank fighters and award titles, but the fight itself is usually licensed and supervised by a local commission, such as a US state athletic commission or the British Boxing Board of Control. That commission inspects the gloves on the night.

Across most of the pro world the weight split is the same. Under the Unified Boxing Rules used by many US commissions, gloves must be between 8 and 10 oz, with 8 oz for every class up to welterweight (147 lbs) and 10 oz from super welterweight up, while the commission can set the glove weight for championship fights. The UK follows a similar pattern with one difference worth knowing. The BBBofC uses 8 oz from flyweight to welterweight, 10 oz from super welterweight up, and 10 oz for all women's pro bouts. state-rulesfightgear

Rules have not always been this settled. Back in 2008 Nevada had been using a provisional rule that put boxers above 135 lbs in 10 oz gloves, before its commission voted to change it after a study found neither size was clearly safer between 135 and 147 lbs. It's a good reminder that local rules can and do change, so always check before a fight. boxingscene

For WBC title fights and other major bouts, gloves usually need to be on the approved list of both the sanctioning body and the commission. That is why you see the same handful of professional brands again and again in championship fights. Fighters often get a choice between approved brands, and the gloves are new, sealed and checked by an inspector before they go on.

The ounce number is only part of the story. Inspectors also look at:

Competition gloves are built to protect both boxers during a fight, but they are much lighter than what most people should use in training.

For bag work and pads, most adults use 12 to 16 oz. For sparring, 16 oz is the common default for adults, and heavier boxers often go up to 18 oz. The usual rule of thumb is to spar in gloves a few ounces heavier than you would fight in, to protect your partner and your own hands.

If you have an amateur bout coming up, it's worth doing a few rounds of pad work in 10 or 12 oz gloves so the lighter weight does not feel strange on the night. Pro fighters often do the same with 8 or 10 oz in the final weeks of camp.

If you are buying gloves for competition rather than training, check these points before you order:

And when in doubt, email the event organiser or your federation before you buy. It takes two minutes and can save you from buying the wrong pair.

Usually 10 oz for lighter men and all women, and 12 oz for heavier men. The exact weight cutoff depends on the federation, so check your rulebook.

Most professional fights use 8 oz gloves up to welterweight and 10 oz gloves from super welterweight and above. In the UK, women's pro bouts use 10 oz in every class.

The weight split is usually the same, but the gloves must be approved by both the commission and the sanctioning body, and they are normally new and inspected before the fight.

Often not. Many tournaments supply approved red and blue gloves for every bout. Some club shows let you bring your own if they carry the right approval label.

No. They are separate organisations, so check which one your national federation follows before you buy approved gloves.

Most adults spar in 16 oz gloves, and heavier boxers often use 18 oz. Your coach or gym may have its own rule.
