Football Spreads Explained
Football Game Odds Typically, when looking at football odds, the date and time of the game will be on the left. Then, directly to the right, you will see two numbers. These numbers will be next to the name of each competing team. NFL point spreads are set by oddsmakers. This is the final outcome they expect one team to have over the other. For example, if the New England Patriots are squaring off against the Miami Dolphins. 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.). Each week, every NFL and college football game is assigned a point spread. The spread, or line as it’s often referred, is the amount of points by which a team is expected to win or lose. So, if the Patriots are playing the Dolphins and are -11.5, they would have to win by at least 12 points in order to cover the spread.

Easily the most popular type of betting for NFL football is “spread” betting or more commonly known as betting against the spread. Bettors who are new to NFL betting or betting in general may be a little confused with NFL spread betting, but it is pretty easy to understand once it is explained to you. We will explain what betting against the spread means below.
What is Betting Against The Spread?
For each NFL game the oddsmakers set a number of points in which the favored team is favored by. Bettors can then either choose for the favored team to win by more than the number of points set, or bet on the underdogs to lose by less than the number of points they are underdogs by or win the game straight up. For example, the spread could be set on the favored team at 6.5 points. This would mean in order for a bet on the favored team on the spread to win they would need to win by more than 6.5 points (7 or more) in order to win the bet. It also means that a bet on the underdog team would win if the underdogs lost by less than 6.5 points (6 or less) or won the game outright.
Example of NFL Spread Bet
Below is an example of what NFL spread betting would look like:
Matchup
- TeamsSpread
- Dallas Cowboys -2.5
- New York Giants +2-5
The negative (-) sign indicates that the Cowboys are the favorites, while the positive (+) sign indicates that the New York Giants are the underdogs. With the spread set at 2.5 points, a bet on the Cowboys would mean that they would have to win by more than 2.5 points (3 or more) in order for you to win that bet. A bet on New York would mean that the Giants would have to either lose by 2.5 or less points (2 or less) or win the game outright in order for your bet to win.
Here is another example with a screenshot taken from 5Dimes.eu during Week 3 of the 2013 NFL season:
Here you can see that the Rams are +3.5, while the Cowboys are -3.5. So for this example the Cowboys are 3.5 point favorites, while the Rams are underdogs of 3.5 points. If you were to bet on St Louis you would need them to lose by 3 or fewer points or just win the game outright. If you were to bet on Dallas you would need the Cowboys to win by 4 or more points.
If the Cowboys were to win by 3 points, lets say 30-27, any bets on the Rams +3.5 would win. Even though the Rams didn’t win the game they covered the spread of 3.5 points.

Now if the Cowboys were to win by 4 points, lets say 31-27, the Cowboys have covered the spread and anyone who wagered on Dallas would win their bets.
Other NFL Spread Betting Information
You may often notice that the spread is sometimes set at an even number such as 3, 6 , 10, etc. In this case if the favored team won by the exact amount set for the spread the bet would be pushed, and all bets would be returned. For example, if the Patriots were 3 point favorites and they won by a FG (3 points) than this would results in a push, meaning no matter which side you bet on you would get your money returned to you.
The most common NFL spreads are usually set between about 2.5-10.5 points, but you will also almost always have games each week with spreads lower than 2.5 and higher than 10.5. In the event that the oddsmakers feel the game doesn’t need a spread, it would be set at 0 or what some call a pick’em (both teams are given even odds to win for this type of bet).
The odds given on the spread are usually -110 unless otherwise noted. It is not uncommon to see one side of the spread being -105, with the other side being -115. If you don’t see any odds listed for each side of NFL spreads you are supposed to assume the odds are -110 on each. Not sure how to read NFL betting odds? Check out our Sports Betting Odds guide.

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.
ATS (Against the Spread) Betting: Case Study
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.
- Kansas City 21 – New England 24
- Kansas City 17 – New England 25
- Kansas City 3 – New England 41
- Kansas City 30 – New England 27

What Can Change the Spread?
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.
Calculating Payouts Against the Spread
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.)
Do Other Sports Have Spread Betting Options?
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.
