How Do Football Spreads Work

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.

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. How does live betting work? While the game is going on, there are numerous opportunities to live bet the Super Bowl. In addition to betting on updated spreads and totals, you can bet on who will.

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.

What is a Point Spread or Side Bet?

A point spread is used in sports betting to even the odds between two unevenly matched teams. Each team is given a point total by the oddsmaker that can either be added or subtracted to the final score, thus factoring into if the bet was won or lost.

Example:

The point spread for Super Bowl XLI was:

If one were to bet on the Colts, the Colts would have to win by a total of 8 points for the bettor to win. If one were to bet on the Bears, the Bears would have to win outright or lose by no less than 6 points for the bettor to win. A 7 point victory by the Colts would equal a push or tie.
