Point Spread Betting: A Beginner's Complete Guide

Point spread betting is a wager on the margin of victory in a game, not simply on who wins. Oddsmakers assign the favorite a negative number, like -3.5, and the underdog a matching positive number, like +3.5. A bet on the favorite only pays out if that team wins by more than the spread. This is because most matchups aren’t evenly matched, and the spread gives bettors on both sides a fair, balanced price.

This guide covers how point spreads are calculated, how to read a spread on a bet slip, how spread betting compares to moneyline and totals wagers, real examples across multiple sports, and a step-by-step walkthrough for placing a spread bet on Caesars Sportsbook.

What Is Point Spread Betting?

Point spread betting is a type of wager that handicaps the stronger team by a set number of points, so bettors are picking against a margin rather than a winner. The favorite is shown with a minus (-) sign, meaning that team must win by more than that number for the bet to pay out. The underdog is marked with a plus (+) sign, meaning that team can lose by fewer than that number, tie the margin exactly, or win outright and still cover.

The point spread exists because sportsbooks need balanced action on both sides of a game to manage risk. If every bettor wagered on the outright winner in a lopsided matchup, the sportsbook would carry far more liability on one side. The spread evens the perceived risk. Most spread bets are priced at standard -110 odds, meaning a bettor risks $110 to win $100 regardless of which side of the spread is chosen.

For example, if a favorite is -7 over an underdog, a $110 bet on the favorite only wins if they win by 8 points or more. A $110 bet on the underdog wins if they win outright, lose by less than 7 points, or the game lands anywhere in that range.

How Point Spreads Are Calculated and Set

Point spreads are set by professional oddsmakers who build an initial power rating for each team, then adjust that rating using real-time information before opening the line to the public.

The starting point is usually a projected margin of victory based on team strength, but sportsbooks quickly move the number in response to injuries, rest, weather, and where the money is landing. Caesars Sportsbook updates odds in real-time.

Team ratings come from statistical models that weigh scoring efficiency, defensive performance, and strength of schedule. Oddsmakers then layer in situational factors: home-field advantage can shift a spread by 1 to 3 points (depending on the sport), a star player's injury report can move a line 2 points or more, and bye weeks can subtract points off the favorite's number.

Once a spread opens, it isn’t fixed. Market makers monitor the handle, the total dollar amount wagered on each side, and adjust the point spread through line movement to balance liability. Sharp bettors (professional or highly skilled wagerers whose action moves lines) can trigger a shift even when the overall ticket count favors the other side. For example, a spread that opens at -3 on Monday might close at -4.5 by kickoff if enough sharp money hits the favorite.

How to Read a Point Spread: Favorites, Underdogs, and Odds

A point spread listing always shows 2 numbers: the spread itself and the odds attached to it. The favorite carries a minus sign in front of the point total, and the underdog carries the same number with a plus sign. The odds next to each side (commonly -110) show how much must be risked to win $100.

Favorites and the Minus Sign

A favorite must beat the final margin listed next to its spread number for a wager to pay out. If a favorite is -3.5 against an underdog, the favorite has to win by 4 points or more for a bet on them to payout. A 3-point win means the favorite won the game, but bettors on the spread lost because they didn’t cover.

Underdogs and the Plus Sign

An underdog gets a cushion equal to the spread number. An underdog at +3.5 pays out the bet by winning outright, or by losing the game by 3 points or less. This is why underdog bettors sometimes cheer for a "backdoor cover," a late score that changes the final margin from a loss to a win against the spread.

Covering the Spread and the Push

Covering the spread means a team beat the point spread, regardless of the final score margin. When a spread lands on a whole number like -7, and the favorite wins by exactly 7, the bet is a push. Both sides get their original stake back with no profit or loss. Sportsbooks frequently use half-point spreads (-7.5 instead of -7 for example), often called "the hook," to eliminate the possibility of a push.

Point Spread Betting vs. Other Bet Types

Point spread betting asks a bettor to predict the margin of victory. Moneyline betting asks who wins the game outright only. Totals (over/under) betting asks whether the combined score of both teams goes over or under a set number. Parlays combine multiple bets (including spreads) into a single ticket with higher risk and higher potential payout.

Point Spread vs. Moneyline

A moneyline bet removes the margin entirely and prices each team based purely on win probability.

Example: Betting the favorite moneyline against an underdog could cost -280 (risk $280 to win $100) because the favorite is predicted to win outright. The same game on the spread (favorite -7) prices much closer to even money at -110.

Betting favorites on the moneyline is more expensive but requires only a win, not a cover.

Point Spread vs. Totals (Over/Under)

Totals betting ignores who wins and instead asks whether the 2 final scores combined will exceed or fall short of a number set by the sportsbook, like 47.5 in a football game. A bettor can combine a spread pick and a totals pick on the same game without either bet affecting the other.

Point Spread vs. Parlay Betting

A parlay strings together 2 or more individual bets into one wager, including point spreads, moneylines, or totals. Parlays only pay out if every leg wins. Parlay spread bets increase the potential payout significantly but also increase risk, since a single missed cover on any leg loses the entire ticket.

Point Spread Examples In Different Sports

Point spread betting applies differently depending on the sport, since scoring frequency changes how spreads are built. Football and basketball use variable spreads that shift game-to-game, while baseball and hockey usually use a fixed spread (called the run line) and puck line.

NFL and NBA Point Spreads

Football and basketball scores vary widely by matchup, so NFL and NBA spreads can range from half a point in a close game to more than 20 points in a significant mismatch.

MLB Run Line

Baseball scores are lower and tighter, so MLB uses a fixed run line instead. Baseball run lines are usually set at 1.5 runs. Betting the favorite on the run line (-1.5) requires that team to win by 2 runs or more. Betting the underdog (+1.5) means that that team can lose by 1 run and the bet still pays out. Because this number usually doesn’t change, sportsbooks adjust the odds instead of the line to balance action.

NHL Puck Line

Hockey uses the same fixed-number approach with the puck line, usually set at 1.5 goals in almost every game. A favorite at -1.5 must win by 2 goals or more. An underdog at +1.5 covers with a win, a tie through regulation, or a loss by exactly 1 goal. Because most hockey games are decided by 1 goal, puck line odds on the underdog can be priced cheaper than the moneyline underdog.

Half-Point Spreads and the Hook

Sportsbooks frequently add a half point in their odds to prevent a push. This is called the hook. A game listed at -3.5 instead of -3 forces a winner on every ticket. That’s why the numbers 3 and 7 (the 2 most common football winning margins) are key numbers that oddsmakers manage carefully.

What to Consider Before Placing a Point Spread Bet

Point spread betting requires a team to win by more than the posted spread or lose by fewer points than the spread. Before placing a wager, bettors should understand how the line, odds, and available features affect the bet. No approach can guarantee a win or profit.

Understand the financial risk: Every point spread wager carries the risk of losing the amount staked. Set personal spending limits in advance, and never wager more than you can afford to lose.

Understand buying points: Buying points allows bettors to adjust a spread in exchange for less favorable odds. Moving a line may change whether a bet wins, loses, or pushes, but the adjusted price also increases the cost of the wager.

Use team and matchup information as context: Factors such as home-field advantage, injuries, recent performance, and matchup history may help bettors understand a game, but they can’t predict or guarantee the outcome.

Review the full wager before placing it: Point spreads and odds can vary or change over time. Confirm the selected team, spread, odds, stake, and potential payout before submitting a wager.

Set personal limits: Deposit, spending, and time limits can help bettors stay within a predetermined entertainment budget. Caesars Sportsbook also provides responsible gaming tools for players who want to manage their activity or take a break.

Frequently Asked Questions

What happens if a team wins by exactly the point spread?

If a team wins by exactly the point spread, the bet is a push. That means the sportsbook returns your original wager with no profit or loss. Sportsbooks often use half-point spreads to prevent a push.

What does covering the spread mean?

Covering the spread means a team beat the point spread requirement, regardless of whether it won or lost the game outright. A favorite covers by winning by more than the spread, and an underdog covers by losing by less than the spread or winning outright.

How is a point spread different from a moneyline bet?

A point spread bet requires a team to beat a specific margin, while a moneyline bet only requires that team to win the game outright. Moneyline favorites cost more to bet because no margin is required.

Why do sportsbooks use half-point spreads?

Sportsbooks add a half point (known as the hook) to eliminate the possibility of a push. For example, a spread of -3.5 instead of -3 guarantees a winner and a loser on every point spread bet.

Can point spread bets be combined into a parlay?

Yes. Caesars Sportsbook allows point spread bets to be combined with moneylines, totals, or props into a single parlay ticket. Every leg of the parlay must win for the bet to pay out.

Why do point spreads move before a game starts?

Point spreads change in response to injury reports, weather, and the amount of money wagered on each side. Sharp bettors placing large wagers can shift a line even when public ticket counts favor the other side.

What sports use a point spread besides football and basketball?

Baseball uses a fixed version of the point spread called the run line, and hockey uses a fixed version called the puck line. Both are usually set at 1.5. Football and basketball use variable point spreads that change based on the projected scoring margin.
