If you’re stepping into the world of sports betting—especially football betting—you’ll quickly come across the term point spread. It’s one of the most common and fundamental ways to bet on games in the U.S., but for beginners, it can be confusing. What does it mean when a team is “favored by 7 points”? And how does that affect whether your bet wins or loses? This guide will walk you through what a point spread is, how it works, and how to read the lines correctly.

What Is a Point Spread?

A point spread is the sportsbook’s way of leveling the playing field between two teams. Instead of simply betting on who will win, the sportsbook assigns a handicap—a number of points that the favorite must win by for the bet to cash.

The goal is to make both sides of the bet equally appealing, so that each team has roughly a 50/50 chance of covering the spread. In other words, you’re not just betting on who wins, but by how much.

For example:

• Kansas City Chiefs -7
• Chicago Bears +7

Here, the Chiefs are 7-point favorites. If you bet on the Chiefs, they must win by more than 7 points for your bet to win. If you bet on the Bears, you win if they either win the game outright or lose by fewer than 7 points.

What Happens in a Push?

Sometimes, the final margin lands exactly on the spread. In the example above, if the Chiefs win by exactly 7 points, it’s called a push. In that case, your wager is refunded—no one wins or loses.

To avoid pushes, sportsbooks often use half-point spreads, such as -6.5 or +3.5. That half-point is known as the hook, and it ensures there’s always a winner and a loser against the spread.

How the Line Moves

The point spread isn’t fixed. It can shift in the days leading up to a game based on betting activity and new information, such as injuries or weather conditions.

If a large amount of money comes in on one side, sportsbooks may adjust the line to encourage more bets on the other side. This process, known as line movement, helps balance the action and limit the sportsbook’s risk.

For example, a team might open as a -3 favorite but move to -4.5 by game day. Understanding why lines move can help experienced bettors find value and better timing for their wagers.

Favorite vs. Underdog

• The favorite has a minus sign in front of the number (e.g., -6.5). This means the team must win by more than that number of points to cover the spread.
• The underdog has a plus sign (e.g., +6.5). This means the team can lose by up to that number of points—or win outright—and still cover the spread.

It’s important to remember that the spread isn’t about who wins the game, but about the margin of victory. A team can win the game but still “lose against the spread” if they don’t win by enough points.

Example: How to Read a Spread Line

Let’s say you see the following line:

Dallas Cowboys -3.5 vs. Green Bay Packers +3.5

• If you bet on the Cowboys, they must win by at least 4 points.
• If you bet on the Packers, you win if they lose by 3 points or fewer—or win the game outright.

If the Cowboys win 27–24, they win the game but fail to cover the spread. A bet on the Cowboys loses, while a bet on the Packers wins.

Point Spreads Across Different Sports

While point spreads are most commonly associated with football, they’re also used in other sports like basketball and even baseball (where it’s called the run line). In high-scoring sports like basketball, spreads can be much larger—often -10.5 or -12.5—while in lower-scoring sports, they tend to be smaller.

In the NFL, typical spreads range from 2.5 to 7 points, depending on team strength, injuries, and home-field advantage.

Tips for Reading and Understanding the Lines

1. Know the key numbers – In football, games often end with margins of 3 or 7 points, so spreads around those numbers are especially significant.
2. Watch line movement – Big shifts can indicate where sharp (professional) money is going.
3. Account for home-field advantage – Sportsbooks usually factor in about 2–3 points for the home team.
4. Shop around – Different sportsbooks may offer slightly different lines, and even a half-point difference can matter over time.
5. Bet responsibly – The point spread is designed to balance the action, not guarantee profit. Always analyze the matchup carefully and wager within your limits.
