What Is Point Spread? A Beginner’s Guide to Spread Betting

What is point spread betting, and why does it appear on almost every game listed at a sportsbook betting platform? The point spread is the most widely used format in sports betting, especially across football and basketball. Rather than simply picking a winner, you are betting on whether a team wins or loses by a specific margin. This guide explains exactly how spread betting works, what the numbers mean, and how to read a point spread before placing your first bet.

If you want to understand how spread odds compare to a money line, our full moneyline vs spread betting guide covers both formats side by side.

Point Spread Betting Explained

A point spread is a handicap set by oddsmakers to create a more balanced betting market between two unevenly matched teams. The perceived stronger team is assigned a negative number, meaning they must win by more than that margin for a spread bet on them to succeed. The underdog receives a positive number, meaning they can lose by up to that amount and still win the point spread bet.

The point spread is not a prediction of the exact final margin. Its purpose is to split betting action evenly across both sides so the sportsbook earns its margin regardless of the outcome. Understanding this distinction is the foundation of all spread betting strategies.

How Does Point Spread Betting Work?

When you place a point spread bet, the final score is adjusted by the spread before the result is graded. If a team is favored by 6.5 points, subtract 6.5 from their final score. When the adjusted result is still positive, they covered. If it is negative, they did not cover the spread.

How does a point spread work for favorites and underdogs? The minus sign next to a spread number identifies the favorite; the plus sign identifies the underdog. A team listed at -6.5 must win by 7 points or more. A team listed at +6.5 must either win the game outright or lose by 6 or fewer points for a spread bet on them to win.

Most spread bets carry odds of -110 on both sides. This is the juice, or vig, which is the sportsbook’s built-in margin for taking the bet. At -110, you wager $110 to win $100. Spread betting work essentially creates a near coin-flip market with consistent pricing, which is why it drives the vast majority of action on football and basketball games.

Point Spread Bet Example

The Kansas City Chiefs are playing the Denver Broncos. Kansas City are set as -6.5 (-110) favorites; Denver are +6.5 (-110) underdogs. Here is what each side of the point spread bet needs:

Side

Spread

Win Condition

Kansas City Chiefs (favorite)

-6.5 (-110)

Must win by 7 or more points

Denver Broncos (underdog)

+6.5 (-110)

Must win outright or lose by 6 or fewer

If Kansas City wins 27-17, the margin of victory is 10 points. The Chiefs cover the spread and a spread bet on them wins. If Kansas City wins 24-20, the margin is only 4 points. The Chiefs win the game but do not cover, and the spread bet on Denver wins.

What does a +7 point spread mean? A +7 spread on the underdog means they can lose by up to 7 points and the point spread bet still pays out. What does a minus-3 spread mean? A -3 spread on the favorite means they must win by more than 3 points to cover. If they win by exactly 3, the bet results in a push and the stakes are returned.

What Does Covering the Spread Mean?

Covering the spread means your team has met the required margin set by the point spread. For the favorite, covering the spread means winning by more than the spread number. For the underdog, it means winning the game outright or losing by fewer points than the spread.

A team can win the game and still fail to cover the spread. For example, if the Kansas City Chiefs are -8 and win by only 6 points, they win the game but the spread bet on them loses. The team that lost the game, the Denver Broncos at +8, would be the winning side of that point spread bet.

How Is the Point Spread Set?

Oddsmakers calculate point spreads using a combination of data-driven computer models and human analysis. Team strengths, recent form, injuries, home field advantage, weather, and travel schedules all feed into the number created. The goal is to produce a spread that attracts roughly equal money on both sides, not to predict the exact final margin.

The point spread can move between its opening line and game time. Spread moves happen when new information arrives, such as a key injury or a shift in betting volume. If the betting public floods one side, the sportsbook adjusts the spread to rebalance the market. Sharp bettors, those with a track record of profitable wagering, can also move a line when they place large bets on one side.

The same game can carry different spreads at different sportsbooks at the same time. Each book sets and adjusts its own betting lines independently. Comparing spreads across multiple sportsbooks before placing your bet is one of the simplest ways to improve your expected return over time.

Point Spread Odds and Payouts

Standard point spread bets are priced at -110 on both sides, making spread betting one of the most consistently priced formats in sports betting. At -110, a winning point spread bet on a $110 stake returns $100 profit, giving a total payout of $210. The $10 difference is the vig, which is the sportsbook’s margin on every losing bet.

To break even on -110 juice over time, a bettor needs to win at least 52.38% of their spread bets. That is the minimum win rate required before a profit appears. If the juice rises to -115 on one side due to heavy public action, the break-even rate increases to around 53.49%.

Spread odds are not always fixed at -110. When one side attracts more bets, sportsbooks may shade the juice to -115 or -120 on the popular side and offer -105 or even +100 on the other. Always check the spread odds on both sides before adding a bet to your bet slip.

Point Spread Payout Example

Here is a direct comparison of a standard point spread bet versus a money line bet on the same game, using a $10 stake on the Kansas City Chiefs:

Bet Type

$10 Stake Returns

Point spread bet

Chiefs -6.5

-110

$19.09

$9.09

Money line bet

Chiefs (heavy fav.)

-280

$13.57

$3.57

The point spread bet pays significantly better than the money line bet on the same team. This is the core reason spread betting is the preferred format for backing heavily favored teams. For more details on how these two bet types compare, see our guide on

Point Spread vs Moneyline: What Is the Difference?

The money line and the point spread both allow you to bet on the outcome of a game, but they measure different things. A money line bet rewards you for picking the winner regardless of the margin of victory. A point spread bet rewards you for picking the team that wins by enough or loses by little enough.

For heavy favorites, the money line requires a large stake for a small return. The point spread on the same team typically offers much better spread odds because the requirement is harder to meet. When you are backing a dominant team in a sport where big margins are common, the point spread often provides better value. When you believe a true underdog can win the game outright, the money line pays more.

Which Sports Use Point Spreads?

Point spread betting is most common in sports where scores are high and the margin of victory varies widely between games. Football and basketball are the two sports where the point spread is the dominant bet type, accounting for the vast majority of spread bets placed each season.

NFL point spread betting is the single biggest market in North American sports betting. NFL games are priced with spreads every week, and the key numbers of 3 and 7 play a central role in how those lines are set. Field goals and converted touchdowns are the most common scoring plays, so games decided by these margins occur frequently, making them the most important numbers in NFL point spread betting.

NBA point spread betting follows the same structure. Basketball games produce high scores and varied margins, making the point spread a natural fit. College football and college basketball also make heavy use of the spread, particularly in games between evenly matched teams or when a strong program faces a significantly weaker opponent.

Not all sports use traditional point spreads. In baseball, the equivalent format is the run line, which is usually fixed at -1.5 for the favorite and +1.5 for the underdog, with the odds shifting instead of the spread number. In hockey, the puck line works the same way, also set at -1.5 and +1.5. Run line bets and puck line bets follow the same cover logic as a standard point spread bet but with a fixed margin.

Low-scoring sports such as soccer do not commonly use point spreads in the same way. In those markets, the money line and Asian handicap formats are more widely used. Spread betting is most meaningful in football and basketball, where eight or more points can regularly separate two teams in a close game.

Point Spread Betting Tips for Beginners

These tips will help you approach point spread bets more effectively. For broader guidance on managing your activity, see our responsible gambling tips.

1.     Understand the spread before placing. Do not simply back the favorite. Check what margin is required and assess whether the perceived stronger team is likely to win by that much.
2.     Shop for the best line. Even a half-point difference can change the outcome of a bet. Comparing spread odds across multiple sportsbooks before placing is one of the easiest ways to improve your results over time.
3.     Track line movement. When the spread moves significantly from its opening number, it often signals where sharp bettors or new information is pointing. Understanding line movement adds valuable context to your decision.
4.     Pay attention to key numbers. In NFL betting, landing on the right side of 3 or 7 can be worth paying extra juice to buy points. These common margins of victory make a significant difference to the final margin of a point spread bet.
5.     Start with single spread bets. A standard point spread bet on one game is a much more controlled starting point than adding parlay point spread bets across multiple legs. Build your understanding of how spread betting works before combining bets.
6.     Understand the juice. At -110 you need to win 52.38% of your spread bets just to break even. Factor the vig into your expectations and never ignore the price attached to a spread.

Frequently Asked Questions

What does plus and minus mean in point spread betting?

The minus sign indicates the favorite, who must win by more than the spread number. The plus sign indicates the underdog, who can win outright or lose by fewer points than the spread to cover.

Can a point spread result in a tie?

Yes. When the final margin of victory exactly matches the point spread, the result is a push and all bets are refunded. Oddsmakers use half-point spreads, known as the hook, to eliminate the possibility of a push.

What happens if the final score lands exactly on the spread?

If the final score lands exactly on the spread, the bet is graded as a push. Your original stake is returned in full with no profit or loss on either side. A half-point in the spread, such as -6.5 instead of -6, prevents this outcome entirely.

What does a +1.5 point spread mean?

A +1.5 point spread means the underdog can lose by 1 point and still win the bet. This format is most commonly seen in baseball run line bets and hockey puck line bets, where the spread is fixed at 1.5 and the odds shift to reflect each team’s probability of covering.
