Point spread betting ranks among the most common ways to wager for sports bettors of all experience levels. Point spreads are set by oddsmakers in an attempt to level the playing field between teams or players by establishing a projected margin of victory. Our expert guide offers a thorough explanation of point spread betting, helping new players understand how to wager on them.

Introduction to point spread betting

Using practical, real-life scenarios is the most straightforward way to ease new sports bettors into point spreads. For example, if Michigan faces Purdue in football, the Wolverines would be heavy favorites with a moneyline bet because they are the superior team.

The point spread gives players access to better odds on a win or a loss by a specific amount.

What is point spread betting?

Point spread betting makes uneven games, such as Michigan vs. Purdue, more balanced for betting purposes. By balancing a matchup, every game holds value for a bettor, even if the best Michigan sportsbooks list one team as a huge favorite to win outright.

However, the point spread isn’t an accurate representation of a sportsbook’s prediction for a game. For example, Michigan may be a 21-point favorite against Purdue, but that doesn’t mean oddsmakers expect the Wolverines to win by three touchdowns.

Sportsbooks create point spreads to attract even betting action on both sides of a wager. They may think Michigan -19 would be a more accurate spread, but setting the number below 21 might draw too much betting handle on the Wolverines.

Instead, the spread gets bumped up to Michigan -21 to give the sportsbook the best chance at turning a profit.

Point spread explained

Terms like “favorite”, “underdog” and “cover” are important to know before wagering on a point spread. Check the table below for a quick guide to key point spread betting phrases.

How does point spread betting work?

Now that we’ve covered the point spread meaning, let’s get a bit more in-depth with specific spreads and what must happen for a wager to win. Reading a point spread may seem confusing at first, but it’s easy to learn once you know what to look for.

NFL point spread betting key numbers: Why 3 and 7 matter most

Your point spread betting strategy should vary by sport. For example, NHL and MLB games are typically low-scoring, while teams can put up big numbers in the NFL and NBA.

If you plan to bet the spread on the Lions or other NFL teams this season, these are the key numbers to watch for based on data from Pro Football Reference.

🏈 Most common final scores in NFL history📊 Point differential🔢 Occurrences before the 2026-27 season20-173 points30227-243 points24423-203 points21717-143 points20024-177 points18113-103 points17024-213 points16116-133 points15017-107 points15024-1410 points141

Three and seven points are the most common final-score margins in the NFL. This is due to the point value of touchdowns and field goals, which drive most matchups to end with a one-possession deficit for the loser.

With a three-point differential holding seven spots in the top 10, sharp bettors look for point spreads hovering around that number. Backing a team to win or lose by three has the highest risk of settling as a push, so point spreads of -2.5 and +3.5 are extremely valuable.

MLB point spread betting: Why the run line number is almost always 1.5

In baseball betting, spreads are also known as the run line. MLB run lines are generally fixed at 1.5 because a majority of games are decided by one run. However, that doesn’t mean you should strictly back underdogs at +1.5.

Factors like a pitching mismatch, recent form, bullpen availability and previous head-to-head matchups could help project a team to win by two runs or more.

Since baseball run lines rarely fluctuate, the value is found with the odds. For example, the Tigers may be heavy favorites on the moneyline, but you can get Detroit at plus odds with the -1.5 run line. Taking a team to cover +1.5 sacrifices a solid payout for a bet that’s more likely to win.

Point spread betting is a fan favorite in the NFL and NBA, but it’s far less popular with MLB. Most baseball bettors target moneylines, player props and futures markets.

NBA point spread betting: Why key numbers matter less than in NFL

NBA scoring has increased drastically in recent years. More teams take a run-and-gun approach with an emphasis on hoisting 3-pointers, while quality defense occasionally falls by the wayside. The uptick in scoring makes it important to know the most frequent point differentials.

🏀 Most common final scores in NBA history📊 Point differential🔢 Occurrences before the 2026-27 season108-1017 points160104-1013 points155100-982 points155105-996 points154106-1042 points153105-1005 points153106-1033 points153105-1032 points152106-1015 points151102-1002 points151

Key numbers are crucial for NFL point spreads because most scoring comes as touchdowns and field goals.

According to the figures above from NBA Scorigami, margins are softer for the NBA due to the continuous scoring. A double-digit point spread is massive in football, but you can find that nearly every night of the NBA season.

With NBA margins relatively even across the board, buying the hook is far less useful compared to the NFL. Bettors can find much better value by checking the odds with multiple sportsbooks, including FanDuel and DraftKings.

Why use the point spread?

Spreads make betting more challenging

Point spread betting is often the most exciting betting option.

Suppose a top-10 Michigan State basketball team plays a game early in the season against a mid-major program that doesn’t come close to matching the Spartans’ talent and ability. Everyone knows MSU’s likelihood of winning is extremely high.

Therefore, betting on Michigan State’s moneyline would yield little profit and hardly be worth watching, as it will almost certainly be a blowout. On the other hand, wagering on the Spartans to win by at least 25.5 points would make the game much more enticing to watch.

Better odds than moneyline bets

Point spread betting offers more favorable odds than moneyline bets, particularly if the best sports betting apps believe the favorite will crush the underdog. Since the moneyline represents the odds of a team winning the game outright, favorites often have short odds that don’t pay out well.

By backing the favorite with the point spread, bettors can get closer to even odds and a more balanced payout if the favorite covers the number.

Widely available across betting markets

BetMGM and other industry-leading sportsbooks offer point spread betting for all major sports and many niche leagues. The popular bet type applies to football (NFL, NCAA), basketball (NBA, WNBA, NCAA), hockey (NHL) and baseball (MLB).

Unlike some player and game props, the point spread isn’t sportsbook-dependent. Wagering against the spread is one of the quickest ways for beginners to learn the ropes.

Beginner tips for point spread betting

Sports bettors are always looking for ways to increase profits. Wins are never guaranteed, but the four tips below will help first-timers find early success with point spread betting.

🎯 Beginner tip💡 Why it matters✅ Do this first📚 Start with a sport you knowFamiliar teams make reading spreads and spotting value far easierDetroit football fans should bet Lions or Wolverines spreads before branching into MLB run lines🔍 Research before you betOddsmakers set razor-sharp lines; gut picks rarely beat themCheck injury reports, recent form and weather on credible sites such as ESPN or Sports-Reference💰 Manage your bankrollSmall, fixed stakes keep betting fun and prevent chasing lossesSet a budget and wager $1-$10 per bet while you learn🛒 Shop for the best spreadA half-point on or off a key number can flip a loss into a winCompare the same line at two or three Michigan sportsbooks before placing a bet

Profitable spread bettors practice discipline rather than firing off bets from the hip. Comparing the lines across multiple sportsbooks takes time and effort, but it’s worth it to find the best number.

Settling for a worse number at your go-to sportsbook could result in a loss when you could’ve won the bet by line shopping and placing it elsewhere.

Signing up and depositing with multiple betting sites grants quick access to the best spread for a given bet, plus you can stack sign-up bonuses.

Best Michigan sportsbooks for point spread betting

Choosing the right sportsbook for your betting profile is vital for maximizing profits and recurring user promos.

The juice, also known as vig, and alternate spread options vary by site. The best Michigan sportsbook promos allow new customers to place early point spread bets with bonuses.

DraftKings is a strong choice if you prefer to bet a point spread before it’s released at other sites. It also has the deepest catalog of betting markets, including alternate point spreads.

The vig at FanDuel is typically lower than other sites, while bet365 offers the smoothest live-betting interface. If a quality loyalty program is a deal breaker, the FanCash rewards system at Fanatics Sportsbook can’t be beat. FanCash is earned every time you wager, and the currency is redeemable for bonus bets or shopping credits at Fanatics.com.

Line shopping requires discipline, but opening an account with at least two sportsbooks is the only way to ensure you get the best value with wagers on the point spread.
