Super Middleweight Is Boxing’s 168-Pound Division
Super middleweight explained: its 168-pound limit, neighboring divisions, weigh-in consequences, title language and how to read the scorecards.
Super middleweight is the professional boxing division above middleweight and below light heavyweight. Its upper limit is 168 pounds (76.2 kilograms) at the official weigh-in.
The division is commonly called the 168-pound division. “Super” does not identify a special title or a superior version of middleweight; it identifies the class between the traditional 160- and 175-pound divisions.
Super middleweight weight range
| Division | Professional weight range | Upper limit |
|---|---|---|
| Middleweight | Over 154 through 160 lb | 160 lb (72.57 kg) |
| Super middleweight | Over 160 through 168 lb | 168 lb (76.20 kg) |
| Light heavyweight | Over 168 through 175 lb | 175 lb (79.38 kg) |
The Association of Boxing Commissions’ regulatory guidelines define super middleweight as over 160 pounds through 168 pounds and list 10-ounce gloves for the class. The WBC and WBO also publish a 168-pound ceiling, with slightly different kilogram figures because of rounding (ABC regulatory guidelines; WBC division limits; WBO championship regulations).
Placed in the full sequence, super middleweight is the 14th of the 17 standard professional divisions, counting upward from minimumweight. See the complete boxing weight divisions in order for every limit and naming variation.
What the 168-pound limit means
The limit applies at the official weigh-in, not when the opening bell sounds. A boxer who records 168.0 pounds has made the super middleweight limit; a boxer at 168.1 pounds is over it.
That does not mean every bout involving a super middleweight must be contracted at exactly 168 pounds. A non-title fight can use a lower contracted limit or catchweight, subject to commission approval. The rules cited above establish a ceiling for the class, not a requirement that a boxer weigh exactly 168 pounds.
Nor should an unofficial fight-night weight be used to rename the contest. Fighters may regain weight after the official weigh-in, but that later reading does not alter the contracted limit or whether they made weight.
Missing weight can change who may win a title
An overweight reading is more than a statistic in a championship bout. The precise consequence depends on the sanctioning body and supervising commission.
Under the WBO’s published rules, a champion or challenger who initially misses receives two additional hours to make the prescribed weight. If the champion still misses, the title becomes vacant at the scale. A challenger who made weight can then win the vacant championship by winning the fight; if the former champion wins, the title remains vacant.
If the champion makes weight but the challenger does not, the challenger cannot win the title. The WBO rules also say the championship becomes vacant if that overweight challenger wins the fight. If both boxers miss, the title is vacated and the contest proceeds as a non-title fight (WBO regulations, Sections 3–4).
That is why three descriptions must be kept separate:
- The contracted bout: the weight and title terms agreed for the contest.
- The official weigh-in: whether each boxer satisfied those terms.
- The official result: what happened after the bell, including whether either boxer remained eligible to win the title.
A fighter can win the bout while remaining ineligible to win the belt.
Super middleweight fights use the usual scoring system
Super middleweight does not have its own judging formula. Judges score rounds under the applicable 10-point must rules, ordinarily giving 10 points to the round winner and fewer to the loser. Knockdowns, dominant rounds and point deductions can alter the numbers.
A 12-round card of 115-113 gives one boxer a two-point final margin after all 12 rounds are added. With no knockdowns or deductions and every round scored 10-9, it represents seven rounds to five. It does not mean the winner landed only two more punches, and overall punch totals are not substituted for round-by-round judging.
For the mechanics behind those totals, see how boxing is scored under the 10-point must system.
The division’s key undisputed milestone
Super middleweight is younger than boxing’s eight traditional weight classes. Guinness World Records dates the modern division to the first IBF super middleweight title fight in 1984. It recognizes Saúl “Canelo” Álvarez as the first undisputed super middleweight champion after he stopped Caleb Plant in the 11th round on November 6, 2021. The victory left Álvarez holding the WBA, WBC, IBF and WBO titles simultaneously in the four-belt era (Guinness World Records).
“Undisputed” describes simultaneous control of the recognized major championships. It is not another weight class, and it should not be confused with winning one organization’s title or topping an independent ranking.
