Boxing matches often end with judges’ scorecards deciding who wins, yet the language around those results can be confusing. “Unanimous decision” is one of the most common terms, but it is not always clear what it covers.
This guide explains what a unanimous decision means, how officials score rounds using the 10 point must system, and how moments like knockdowns or fouls shape the result. You will also see example scorecards so the numbers make sense at a glance.
Finally, it explores why judges sometimes disagree, how a unanimous decision affects betting settlements, and practical ways to read scorecards during a bout so the announced verdict never feels like a surprise.
What Is a Unanimous Decision in Boxing?
A unanimous decision is a result given at the end of a boxing match that goes the distance, meaning all scheduled rounds are completed without a knockout.
Each of the three judges scores the fight independently. If all three agree that one boxer performed better and award them higher totals, the win is declared a unanimous decision.
This simply means there is complete agreement among the judges about which boxer was superior based on the scoring criteria.
Unanimous decisions differ from split or majority decisions, where the judges’ choices do not fully align. With a unanimous decision, there is no disagreement and every official has reached the same conclusion about the winner.
How Do Officials Reach a Unanimous Verdict?
Each boxing match is judged by three officials who watch the fight closely and score each round independently. Judges focus on clean punches, defence, ring generalship and effective aggression.
After all rounds are completed, the judges’ scores for each boxer are added up. A unanimous verdict is reached if all three judges have the same boxer ahead on their scorecards.
This agreement means every official saw the match in a similar way and all gave the victory to the same competitor. It often happens when one boxer is clearly ahead, though it can also occur in competitive fights where the same boxer edges several close rounds.
With that in mind, how do judges actually turn what they see into numbers round by round?

How Do Judges Decide Round Scores?
Each round is scored separately by the three ringside judges using a standard set of guidelines. They look for clear punches that land on the target area, effective defence, ring positioning, and who is controlling the action.
The boxer who does better in these areas receives the higher score for that round. Scores are written down immediately after the bell, so judges commit to their view without discussing it with others.
The framework they use is known as the 10 point must system, which keeps round scoring consistent across a fight.
Understanding the 10-Point Must System
The 10 point must system is the standard scoring method used in most professional boxing matches. In each round, the judge must give 10 points to the boxer they believe won the round, while the other boxer usually receives 9 points or, if there was a knockdown or penalty, 8 or fewer.
This structure continues for every round in the contest. Over time, small advantages build a lead, while knockdowns or deductions can create wider gaps on the cards.
Example Scorecards and Typical Totals
An example of a simple scorecard in a 12 round match might look like this:
Boxer A: 10-9, 10-9, 9-10, 10-8, 10-9, 9-10, 10-9, 10-9, 10-9, 10-9, 10-9, 10-9.
Adding these numbers, Boxer A finishes with a total of 117, and Boxer B has 111. That kind of margin usually reflects a mix of steady round wins and one strong round with a knockdown. Each judge produces their own card, and the totals at the end determine the verdict.
How Do Knockdowns, Fouls and Ring Control Affect Scoring?
Judges consider more than the number of punches landed. Key moments, such as knockdowns, fouls and a boxer’s ability to control the ring, can shift a round decisively.
A knockdown happens when a boxer is sent to the canvas by a legal punch and must beat the referee’s count to continue. A round with a clean knockdown is typically scored 10-8 to the boxer who scored it, and multiple knockdowns can widen that margin further.
Fouls, such as low blows or excessive holding, may lead to point deductions. The referee signals these penalties to the judges, who reduce the offending boxer’s score for that round.
Ring control refers to a boxer’s ability to dictate pace, distance and positioning. Judges may reward the boxer who sets the terms of the exchanges, especially when other scoring criteria are close.
Because judges weigh these elements in real time, two close rounds can look different from different angles.
Common Reasons Judges Award Different Scores
Judges sometimes see rounds differently because scoring involves judgement. Each judge sits on a different side of the ring, which can affect their view of what lands cleanly or which actions matter most.
Some judges place more emphasis on clean, effective punching, while others give extra weight to defence or aggression that forces the action. Two judges can watch the same exchange and value different parts of it.
Differences tend to show up in close rounds. If both boxers perform at a similar level, a judge might favour one fighter’s accuracy or the other’s ring control, leading to varied scores. Unclear moments, such as borderline fouls or partially blocked shots, add to that split in interpretation.
Those differences feed directly into the range of verdicts you hear announced after the final bell.
What Happens When Judges Disagree?
If judges do not all see the fight the same way, the result is not a unanimous decision.
When two judges award the win to one boxer but the third picks the other, it is called a split decision. If two judges agree on the winner and the third judge scores the bout as a draw, the result is a majority decision.
Sometimes, all three judges give different scores. For example, if one judge favours each boxer and the third calls it a draw, the overall result depends on the totals. If no single boxer is awarded the win by a majority of the judges, the contest is declared a draw. In that situation, neither boxer is considered the winner based on the scorecards.
How Does a Unanimous Decision Affect Betting Settlements?
A unanimous decision is a specific outcome offered by many bookmakers. If a customer selects a boxer to win by unanimous decision, the bet only settles as a winner if all three judges choose that boxer on their scorecards.
Other verdicts, such as split or majority decisions, do not qualify for that market. For bets placed on a boxer simply to win by decision, these are usually settled regardless of the type of points victory, but terms vary. Always check the rules of the market before placing a bet and only stake what you can afford to lose.
How Can Viewers Interpret Scorecards During a Fight?
During a bout, broadcasters sometimes show unofficial scorecards. These offer a guide to how the action might be judged, but they do not decide the result.
Official scorecards are revealed once the match ends. To read them, look at the round by round breakdown for each judge, noting any 10-8 rounds or deductions that widened a gap. A 10-9 round usually means one boxer was a little better, while 10-8 reflects a more dominant spell, often linked to a knockdown. Point deductions are marked, which is how scores such as 10-8 or 10-7 can appear even without a knockdown in that same round.
If all three judges clearly favour one boxer in most rounds, it points to a strong performance. When rounds are split across the cards, it signals a competitive fight where different judging priorities came into play. Understanding how those scores are built makes unanimous decisions, and every other verdict, much easier to follow.
