In March 2014 Vasiliy Lomachenko, who had lost once in close to four hundred amateur bouts and won two Olympic gold medals, boxed for a world title in his second professional fight and lost a split decision to Orlando Salido, who had missed the featherweight limit, been stripped on the scales and then spent twelve rounds leaning on him, hitting him low and making him carry the weight. Lomachenko won a title in his next fight. But the best amateur of his generation had learned in one night that he had changed sports.

The short answer: the punches are the same and almost nothing else is. Three rounds become twelve, the headguard comes off, the gloves shrink, the judges reward hurt rather than volume, the referee stops protecting you, and somebody has to pay you. Here is what changes, in the order you will notice it.

Three rounds, or twelve

An amateur bout is nine minutes long: three rounds of three minutes with a minute between them, for elite men and women alike. A professional debutant boxes four rounds, moves to six and eight as the promoter's confidence grows, and boxes ten or twelve for a title; championship fights were fifteen rounds until the death of Duk-koo Kim after fourteen rounds with Ray Mancini in 1982 pushed the WBC, and soon the other bodies, to twelve. Nine minutes is a sprint. Thirty-six is arithmetic: a pace that wins three rounds loses the last six, and every amateur who turns pro spends a year learning to spend less.

Gloves, headguards and the vest

Amateurs box in 10 oz gloves in the lighter classes and 12 oz in the heavier ones, in a vest, and – for women, youth and juniors – in a headguard. Elite men lost the headguard in 2013, when AIBA's own injury data suggested it reduced cuts but not concussions, and boxed bare-headed at Rio, Tokyo and Paris while the women kept theirs. Whether World Boxing keeps that split for Los Angeles 2028 is unsettled.

Professionals box in 8 oz gloves up to welterweight and 10 oz above, bare-headed and without a vest. Two ounces of padding does not sound like much. Anyone who has moved from 12 oz to 8 oz in sparring can tell you what it feels like from the other end.

What the judges reward

Both codes use the 10-point must system now; How Boxing Is Scored has the arithmetic. The difference is what earns the ten. The IBA's criteria put the number of quality blows on the target area first, then domination by technical and tactical superiority, then competitiveness. The professional criteria are clean punching, effective aggression, ring generalship and defence, and a hurtful punch outweighs three busy ones. An amateur who touches you forty times with the jab has probably won the round. A professional who touches you forty times and eats one right hand that buckles his knees has probably lost it.

How much the referee gets involved

An amateur referee is a protector first: a standing eight count for a boxer who is hurt but upright, an automatic stop after three counts in a round or four in the bout, an earlier halt for a cut, and RSC – referee stops contest – on the record rather than TKO, which tells you how the sport thinks of it. A professional referee under the ABC and WBC rules has no standing count to give, and in most title fights the three-knockdown rule is waived, so a boxer can be dropped three times in a round and sent back out. He can still stop the fight whenever he likes. The rule book just gives him fewer tools and more discretion.

Medicals, and the days you are not allowed to fight

Amateurs see a doctor on the morning of every bout, and a boxer knocked out by a head blow is barred from boxing and sparring for at least thirty days, longer for a second knockout within a few months. Professionals hold a licence from a commission – the British Boxing Board of Control, a state commission in the United States – that demands an annual medical, an eye examination, blood tests and, in Britain and several American states, a brain scan; after a knockout the commission suspends you, typically for thirty to ninety days. The paperwork is heavier as a professional. The protection during the fight is lighter.

How a career actually works

The amateur ladder is a public building with the stairs marked: club, regional championship, national championship, national squad, World Championships and, in the right year, the Olympics. Nobody pays you beyond expenses until you are very good, and even then it is prize money, not a purse. What you get is bouts, dozens of them, matched by weight and experience, for free.

Turning professional is a business decision dressed as a sporting one. You apply to a commission for a licence, sign with a manager, who in Britain may take up to a quarter of your purse, and with a promoter, who puts you on shows and expects you to sell tickets. The belts belong to four private organisations – the WBA, founded as the NBA in 1921, the WBC in 1963, the IBF in 1983 and the WBO in 1988 – each with its own champion in every division and its own sanctioning fee. A purse on a small-hall show can be a few hundred pounds after the manager's cut; a purse for the biggest fights runs to nine figures. Most careers end closer to the first number.

Why a new pro fights a man with three wins and forty losses

Because a debutant needs rounds, not risk. A journeyman's record reads like a phone number nobody would dial – one English journeyman retired after three hundred fights with a dozen wins – and he is the most important man in the building for a prospect. He has boxed four-rounders every fortnight for years, does not get hurt, does not chase a knockout that would cost him his next booking, and shows a young boxer every trick a headguard and a referee used to hide. The prospect learns to pace six rounds, then eight, and keeps the zero on his record that promoters and television have decided matters more than anything he did as an amateur. It looks ridiculous from outside. It is how the sport has always worked.

Pace and style: sprint against marathon

Watch an Olympic final and a world title fight back to back and you see two postures. The amateur stands taller, hands higher, bounces in and out and throws straight, fast, in bursts, because the judges are counting and the round is short. The professional sits lower, walks rather than bounces, spends two rounds finding out what is there and invests in the body because the return comes in round nine. Lomachenko's first year as a professional was a sprinter learning that the finish line had moved.

What a beginner should choose

Amateur. Not because it is easier – it is not, at any level where people are trying – but because everything about it is built for someone who does not yet know what they are. The club matches your first bout by weight and experience, the referee stops it before you learn something you cannot unlearn, and the doctor sees you before and after. You will get twenty or forty bouts in the time a professional gets six, and find out whether you are a boxer or someone who enjoys boxing, a distinction worth discovering in 10 oz gloves.

White-collar and unlicensed shows exist; their medicals and matchmaking vary. Go to a club. Spend a year fixing the jab, starting with The Jab: Five Most Common Mistakes. Box a few dozen times. Then, if the phone rings and you still want it, turn professional knowing exactly what changes, which is everything except the punches.

Where to go next

Frequently asked questions

How many rounds are there in amateur boxing?
Three rounds of three minutes for elite men and women under IBA and Olympic rules, with a minute between them. Juniors and younger age groups box shorter rounds. Professional bouts run from four rounds for a debutant to twelve for a championship.
Do amateur boxers still wear headguards?
Elite men have boxed without them since AIBA removed them in 2013, including at Rio 2016, Tokyo 2020 and Paris 2024. Women, youth and junior boxers still wear them under IBA rules. Professionals never do.
What size gloves do amateur and professional boxers use?
Amateurs use 10 oz gloves in the lighter classes and 12 oz in the heavier ones. Professionals use 8 oz up to welterweight (147 lb / 66.7 kg) and 10 oz above it under most commissions, which is one reason a pro punch does more damage.
How is amateur boxing scored differently from professional boxing?
Both use the 10-point must system, but amateur bouts have five judges rather than three and the criteria put the number of quality blows first, followed by technical and tactical domination and competitiveness. Pro judges weigh clean punching, effective aggression, ring generalship and defence, and a hurtful punch counts for more than a busy one.
Why do professional boxers start their careers against fighters with losing records?
Because a debutant needs rounds, not risk. Journeymen are durable, experienced and rarely win, so a promoter can build a prospect's record and sell tickets while the boxer learns to box six and eight rounds without headguards and in smaller gloves. The step up comes later, usually when television arrives.
Should a beginner start in amateur or professional boxing?
Amateur, almost without exception. The club matches you by weight and experience, the referee protects you, the medicals are compulsory, and every serious professional came through it. Turning pro is a business decision to make once you have a few dozen bouts and know what you are for.
