What is Point Spread Betting? How Does It Work?

What is a point spread?

A point spread, or simply “the spread”, is a sports betting number made by oddsmakers at sportsbooks that serves as a handicap between two opponents. Because not all teams are equal in skill, oddsmakers use spread betting to level the playing field.

The point spread is quickly becoming part of the mainstream sports conversation, used in sports betting as the great equalizer when it comes to comparing teams. It’s most often used in NFL and college football betting, as well as NBA and NCAA basketball. In baseball, the spread is called the run line and in hockey, it is called the puck line.

How to read a point spread

Let’s look at the point spread from Super Bowl LIV as an example of how to read a point spread. 

The point spread from Super Bowl LII between the San Francisco 49ers and the Kansas City Chiefs

Based on these NFL odds, the Kansas City Chiefs are the favorite to win. We know this because they have the minus sign (-) in front of their spread. The San Francisco 49ers are the underdog because they have the plus sign (+) in front of their spread.

Kansas City was a 1.5-point favorite to win the Super Bowl. This means they needed to win by two or more points to cover the spread. San Francisco was a 1.5-point underdog. They could have lost by 1 point (or won the game outright) and still covered the spread.

Kansas City ended up winning the Super Bowl 31-20. The 11-point margin of victory was greater than the -1.5-point spread, meaning they covered the spread.

How to bet against the point spread

Before making a point spread bet, you’ll need to decide who you think will cover the spread and if you should make the bet now or later — because the spread might change. Then you’ll want to understand the vig/juice on the spread and how much you stand to win. 

Which team will cover the spread?

The first thing you need to decide on is which team you think will cover the spread. Do you want to lay the points by betting with the favorite or do you want to take the points by betting with the underdog?

Why does the point spread change?

The point spread, like all sports betting markets, is an active market. Oddsmakers can and will move the spread based on a number of factors, including:

  • Which side professional bettors are wagering on
  • The amount of money taken in on one side of the spread versus the other
  • Breaking news that relates to the game (injuries, weather, etc.)

What does -110 mean?

You also need to understand how odds work in point spread betting. In the above Super Bowl example, you’ll notice a -110 next to both spreads (assuming you’re using American odds). This is called the vig (short for vigorish) or the juice. It is a price that the sportsbooks charge to bet into this market and is similar to the rake in poker. With a vig of -110, you’ll need to wager $110 to win $100.

How much can I win?

The amount of money you can win from point spread betting depends on two things:

  1. The amount of money you wager
  2. The price of the odds at the time you make the bet

Many American bettors wager on a “to win” basis when betting odds with a negative sign (-), meaning they decide how much they want to win before deciding how much to risk. Above, we mentioned that at odds of -110, you need to wager $110 to win $100. Likewise, you’d need to wager $120 to win $100 if the odds are -120.

How is a point spread determined?

The biggest factor that oddsmakers look at when making a point spread is the difference in skill level between the two teams. Most oddsmakers will have their own set of power rankings that will help determine the spread for each game.

There are other factors that come into play as well, including:

  • Current form
  • Location of the game (home-field advantage)
  • Injuries
  • Weather

Point spread betting in baseball

The point spread in baseball odds is often referred to as the run line. In MLB, the run line is almost always set at 1.5, meaning the favorite needs to win by two or more runs. 

Run line odds in MLB betting

Here, the Houston Astros (-1.5) were the favorite in Game 7 of the 2019 World Series with a vig of +155. A bettor could have won $155 on a $100 bet if the Astros had won by two or more runs. 

The Washington Nationals (+1.5) were the underdog with a price of -185, meaning it took a $185 bet to win $100 for Washington run line bettors. The Nationals won the game outright, so they covered the run line, but it also could have lost by one run and still covered.

Point spread betting in hockey

The point spread in hockey odds is often referred to as the puck line. In the NHL, the puck line is almost always set at 1.5, meaning the favorite needs to win by two or more goals.

Puck line odds in NHL betting

Above we see that the Boston Bruins (-1.5) were the favorite with a vig of +145. This means that a $100 bet would have paid out $145 if the Bruins had won by two or more goals. 

The Dallas Stars (+1.5) were the underdog with a vig of -165. A bettor needed to wager $165 to win $100 on the Stars puck line. Boston won the game outright 4-3, but Dallas covered the puck line because it only lost by one goal.
