Point spread betting is the most popular form of sports betting. The vast majority of sports wagers use a point spread thanks to the popularity of football and basketball. Even though this type of betting is so popular, it may take awhile to understand.
The point spread is sometimes known as an equalizer for sportsbook operators. All teams aren’t created equally, so sportsbooks can create a point spread for a game so that each team playing has an almost even chance of winning the game. In a way, the point spread will even the field for both teams.
The point spread gives a reason for bettors to risk money on both teams. The better team playing in the game is considered favorite. They have to win by the point spread offered by the sportsbook. The favorite in a game is listed as being minus (-) the point spread.
The point spread is a handicap placed on one team for betting purposes only, it has no place in the game itself. It's designed to give both teams an equal chance at winning in the context of wagers. It's designed to give both teams an equal chance at winning in the context of wagers. Spread definition is - to open or expand over a larger area. How to use spread in a sentence.
The worse of the teams playing in the game is called the underdog. The bettor wins if this team wins the game outright or loses by an amount smaller than the point spread. The underdog in a game is listed as being plus (+) the point spread.
Let’s use the upcoming Super Bowl between the Kansas City Chiefs and Tampa Bay Buccaneers as an example.
Using this example, the Chiefs opened as 3-point favorites over the Buccaneers (currently Chiefs ). The Chiefs need to win by 4 or more points to cover the spread.
Likewise, the Buccaneers opened as 3-point underdogs. That means the Buccaneers would need to win the game outright or not lose the contest by 4 points or more. If the line is Chiefs -3 and they win by exactly 3 points, the betting result is a “push” and bettors for both sides would get their wagers refunded.

Point spreads are usually set with -110 odds, but pricing often fluctuates at online sportsbooks. This is the sportsbook operators’ house edge. The odds guarantee the sportsbook operator will see a little money over time. When the odds are set at -110, the bettor must wager $110 to win $100 (or $11 to win $10).
The odds on a point spread are most commonly known as the vigorish or “vig” for the sportsbook. You might hear this small profit margin for the sportsbook called the “juice” by some sports bettors.
A “pick em” (sometimes seen as “pick”) is when the teams have a point spread of zero, meaning neither team is favored. In this instance, you’re essentially picking moneyline and your bet will be determined on the winner alone.
A spread of minus-seven (-7) means that a is favored to win the game by a touchdown (technically, a touchdown and the extra point). A team favored by -7 must win the game by eight or more points to win the bet. If the team wins by seven, the result is a “push” and the bet is refunded.
A spread of +7 means the team must win the game or lose by fewer than seven points to win the bet. A loss by seven would result in a push.
A -3 spread means that the favorite must win by more than a field goal to win the wager. A three-point win would result in a push and the sportsbook would refund the wager.
A spread of +3 means the team listed as the underdog must win the game or lose by fewer than three points to cash the bet. A three-point loss would be graded as a push by the sportsbook and the bet would be refunded.
In 2019, the Baltimore Ravens led the NFL in point differential per game at +13.7 points; the Miami Dolphins ranked last in the NFL in point differential per game at -11.7. Even Kansas City– known for their explosive offense– had an average point differential in 2019 of just 9.7 points. The net point differential in the NFL is -14.1, or -0.9 points per game. Basically, the talent differential in the NFL is so minute that even mismatched teams often draw games within a score of each other.
NFL spreads are most commonly between one point and four, with six being a heavy favorite and extremes coming out around 15-20 point favors. (For those wondering, the 1941 Chicago Bears hold the NFL record of point differential at +15.7 points per game. Conversely, Ohio State had a +33.1 average point differential in 2019.)
Sportsbook operators often aim to have equal money on both sides of a point spread. When the money is exactly split the sportsbook operator will see the exact vigorish as their profit margin. If all things are equal over time this will maximize how much money the sportsbook operator can make.
In an effort to have equal money on both sides of a wager, the sportsbook operator will move the point spread to attract money on the side that customers aren’t betting on. The odds for a point spread might change before the actual point spread. There are certain point spread numbers, like 3 and 7 in football, the sportsbook operators would like to avoid moving away from since the final score margin falls on these two numbers most often.
For example, if a lot more money is wagered on the New England Patriots -3, the vig may shift from -112 to -115 and -120 before the line moves to -3.5.
Football and basketball games are mostly bet using a point spread. The less popular major sports, baseball and hockey, are mostly bet using a moneyline. In an effort to make baseball and hockey more appealing to point spread bettors, the sportsbook operators offer run and puck lines, respectively.
These alternative lines give point spread bettors a chance to wager on other sports using a more familiar method of betting. Since points (runs and goals) aren’t as easy to come by in baseball and hockey, the odds with the lines may have a wider spread than a football or basketball game.

Most sporting events have a perceived favorite, so applying a spread to the game is the bookmakers’ way of creating an even playing field. This is most often seen when betting on the NFL. When you bet “against the spread,” it’s not enough for the favorite to win the game; now, they have to win by more than a specified amount (the spread) in order for them to “cover the spread.”
As we explained with moneyline betting, a negative number (-) indicates the favorite and a positive number (+) indicates the underdog.
As you can see, New England is the favorite in this game by 7.5 points, since they have the negative number. You will often see half-points attached to the spread to avoid “pushes,” or ties for the newbies. As we covered in our how to read odds guide, games with half-point spreads are said to contain a “hook.”
In this circumstance, favored New England is said to be “laying” 7.5 points. This means you subtract 7.5 points from their total score when the game concludes. If they still have more points than the Chiefs, then they “covered.” Therefore, the Patriots will have to win the game by at least 8 points for you to win your bet.
While New England is “laying” 7.5 points, Kansas City is “getting” 7.5 points. This means you add 7.5 points to their total score when the game concludes. If, after doing so, they have more points than the Patriots, then they “covered.” So, in order to win your bet, the Chiefs just cannot lose the game by 8 points or more. For example, if the Chiefs only lose by 3 points, you would win if you bet on Kansas City.
Here are a couple of mock outcomes, with the team who covered the spread in bold.
The spreads in football games are subject to change based on where the money is going and weekly injury reports. If Tom Brady is hit by the Madden Curse before the season even starts and is unable to suit up, you’ll see the spread decrease, likely landing around New England -3.5.
Now you may have noticed in the chart above that there is a three-digit number next to each spread, which looks an awful lot like a moneyline. It is, in essence. Those negative numbers (-110 in this case) indicate how much you have to bet in order to win $100. (Sportsbooks still take their cut when you’re betting against the spread.)
Generally, you will see “even bets,” meaning the payout is the same no matter who you bet on. But that’s not always the case, as you’ll see in the chart for our next example.
If the result of this game is Seattle 21 – Green Bay 28, would you win if you bet on Seattle to cover?
(NO! They lost by more than three points.)
Betting against the spread on the NFL is undoubtedly the most popular form of spread betting, but there are other options.
You will also see point spreads in hockey, baseball, and soccer. They are referred to in different terms, but they refer to the same principle of operation as the spread.
In hockey, the spread is called apuck line; in baseball, it is a run line; and in soccer, it is a goal line.
Puck lines and run lines are almost always fixed at 1.5.
