A point spread is the number of points a sportsbook adds to the underdog or subtracts from the favorite to make both sides of a bet roughly equal. If you see Chiefs -3.5, Kansas City must win by 4 or more points for that bet to win. If you see Broncos +3.5, Denver can lose by 3 or fewer — or win outright — and the bet still cashes. The minus sign always marks the favorite, the plus sign always marks the underdog, and the number is the margin that decides the bet, not the winner of the game. A spread ending in .5 can never end in a tie, and the odds beside it, usually -110, are what the sportsbook charges you to place the bet.
This guide answers the exact questions people ask about spreads — what +1.5, +3.5, -7.5 and +8.5 actually mean, how the “.5 hook” works, what -110 costs you, and how spreads differ across the NFL, NBA, MLB and soccer.
What Does a Point Spread Mean in Betting?
A point spread represents the expected margin of victory between two teams. Instead of asking “who wins?”, it asks “who wins by how much?” The favorite is handicapped with a negative number and the underdog is given a head start with a positive number, so that betting either side is close to a coin flip.
Take a spread of 3 points. You will see Team A -3 and Team B +3:
- Team A (-3) is the favorite and must win by 4 or more points.
- Team B (+3) is the underdog and cashes by winning outright or losing by 1 or 2 points.
- If Team A wins by exactly 3, the bet is a push and your stake is refunded.
What Does +1.5 Mean on a Spread?
+1.5 means the underdog can lose by 1 point and your bet still wins. It is the smallest common spread and shows the sportsbook sees the two teams as nearly even. A bet on +1.5 wins if that team wins the game outright or loses by exactly 1 point. It loses only if the team loses by 2 or more.
You will see +1.5 most often in baseball, where it is called the run line, and in hockey as the puck line. Because so many baseball and hockey games are decided by a single run or goal, that half-point carries real weight.
What Does +3.5 Mean on a Spread?
+3.5 means the underdog can lose by up to 3 points and the bet still wins. This is one of the most important numbers in football betting, because 3 points is the value of a field goal and the single most common margin of victory in the NFL.
The difference between +3 and +3.5 is bigger than it looks. At +3, a 3-point loss is a push and you get your money back. At +3.5, that same 3-point loss is a win. That extra half-point is why sportsbooks charge more for it.
What Does a Negative Spread Mean?
A negative spread marks the favorite, and the number is how many points that team must win by. A team at -7 has to win by 8 or more for the bet to cash. Winning by exactly 7 is a push; winning by 6 or fewer, or losing, means the bet loses.
The bigger the negative number, the wider the gap the sportsbook sees between the two teams. A -14 spread signals a heavy mismatch; a -1.5 spread signals two teams it considers almost identical.
What Does a +8.5 Point Spread Mean?
+8.5 means the underdog can lose by up to 8 points and still cover. The bet wins if that team wins outright or loses by 8 or fewer, and loses only if the margin reaches 9 or more.
In the NFL, +8.5 sits just above two scores. A team down by 8 can tie the game with a touchdown and a two-point conversion, so 8.5 keeps the underdog live in a way that +7.5 does not.
Point Spread Numbers Explained: Quick Reference Table
Use this table to read any spread at a glance. “Covers” means the bet wins.
| Spread | Side | Bet wins when | Bet loses when |
|---|---|---|---|
| -1.5 | Favorite | Wins by 2 or more | Wins by 1, or loses |
| +1.5 | Underdog | Wins, or loses by 1 | Loses by 2 or more |
| -3 | Favorite | Wins by 4 or more | Wins by 1–2, or loses (win by 3 = push) |
| +3.5 | Underdog | Wins, or loses by 1–3 | Loses by 4 or more |
| -7 | Favorite | Wins by 8 or more | Wins by 1–6, or loses (win by 7 = push) |
| +7.5 | Underdog | Wins, or loses by 1–7 | Loses by 8 or more |
| +8.5 | Underdog | Wins, or loses by 1–8 | Loses by 9 or more |
| -14 | Favorite | Wins by 15 or more | Wins by 1–13, or loses (win by 14 = push) |
Why Do Point Spreads End in .5?
The half-point — known as “the hook” — exists to remove the possibility of a tie. No team can score half a point, so a spread of 3.5 guarantees a clear winner and loser on every bet, with no refunds.
Compare the two outcomes when a favorite wins by exactly 3:
- Spread of -3: push. Your stake comes back, nobody profits.
- Spread of -3.5: loss. The favorite needed 4.
This is why experienced bettors talk about “buying off the hook” or “getting the hook” — moving from -3.5 to -3, or from +3 to +3.5, changes real outcomes on key numbers like 3 and 7 in football.
What Does -110 Mean Next to the Spread?
-110 means you must risk $110 to win $100. That extra $10 is the sportsbook’s commission, called the vigorish, or “vig” or “juice.” It is charged on both sides of the spread, which is how the book makes money regardless of who covers.
| Odds | Risk | To win | Total return if it wins |
|---|---|---|---|
| -110 | $110 | $100 | $210 |
| -120 | $120 | $100 | $220 |
| +100 | $100 | $100 | $200 |
| +110 | $100 | $110 | $210 |
At standard -110 pricing you need to win roughly 52.4% of your spread bets just to break even. That figure is the reason line shopping matters: taking -105 instead of -110 on the same side lowers the break-even point you have to clear. Comparing prices across the best sportsbooks before you bet is the simplest edge available to a recreational bettor.
What Does Spread Mean in NFL Betting?
In the NFL, spreads are built around the key numbers 3 and 7, because field goals are worth 3 points and touchdowns with an extra point are worth 7. A large share of NFL games land on exactly those margins, which is why lines cluster there and why the half-point around them is priced so aggressively.
Typical NFL spreads run from -1 to about -14. Anything beyond -14 signals the book expects a blowout, and those games often see the favorite rest starters late, which affects the final margin without affecting who won.
What Does Spread Mean in NBA Betting?
NBA spreads are wider than NFL spreads because basketball scores are much higher. A typical NBA line runs from -2 to -12, and there are no dominant key numbers the way 3 and 7 dominate football, since baskets come in 1, 2 and 3 points.
Two factors move NBA spreads more than anything else: injury news and rest. A star ruled out an hour before tip-off can move a line several points, and teams playing the second night of a back-to-back are routinely handicapped for fatigue.
What Does Spread Mean in MLB and Soccer Betting?
In baseball and soccer the spread is almost always fixed at a small number, because scoring is low. The mechanics are identical — a favorite gives points, an underdog receives them — but the terminology and the size of the number change.
| Sport | Name for the spread | Typical line |
|---|---|---|
| NFL | Point spread | -1 to -14 |
| NBA | Point spread | -2 to -12 |
| MLB | Run line | Almost always -1.5 / +1.5 |
| NHL | Puck line | Almost always -1.5 / +1.5 |
| Soccer | Asian handicap / goal line | -0.5 to -2.5 |
Soccer adds one twist worth knowing: the Asian handicap can use quarter-goal lines such as -0.25 or -0.75, which split your stake across two outcomes. A -0.25 line puts half your bet on the draw-no-bet result and half on -0.5.
Spread vs Moneyline: Which Should Beginners Use?
Use the moneyline when you are confident a team wins; use the spread when you think a game stays close. A moneyline bet only asks who wins. A spread bet asks by how much, and it is priced so that both sides sit near even money.
| Point spread | Moneyline | |
|---|---|---|
| What you predict | Margin of victory | Winner only |
| Typical odds | Around -110 both sides | Varies widely |
| Big favorite | Must cover a large number | Wins but pays very little |
| Big underdog | Gets a large head start | Pays a lot, rarely wins |
Why Do Point Spreads Change Before Kick-off?
Spreads move for two reasons: new information, and money. An injury to a starting quarterback, a late scratch in the NBA, or a weather front that will suppress scoring all cause books to re-price a game. Separately, if far more money lands on one side, the book shifts the line to attract action on the other side and balance its exposure.
This is why the number you bet matters as much as the team you bet. Taking +3.5 on Monday and watching the line settle at +2.5 by Sunday means you hold a better number than everyone who waited — and on key numbers like 3, that difference decides bets.
Key Takeaways
- The minus sign is the favorite, the plus sign is the underdog, and the number is the margin that settles the bet.
- .5 spreads can never push — there is always a clear win or loss.
- -110 is standard pricing, and it means you need to win about 52.4% of your bets to break even.
- 3 and 7 are the key numbers in football; half-points around them are the most valuable in betting.
- MLB and NHL are nearly always ±1.5; soccer uses the Asian handicap instead.

FAQ
What does +1.5 on a spread mean?
+1.5 means the underdog can lose by 1 point and the bet still wins. It wins if that team wins outright or loses by exactly 1, and loses only if the team loses by 2 or more. In baseball this is called the run line and in hockey the puck line.
What does +3.5 mean on a spread?
+3.5 means the underdog can lose by up to 3 points and still cover. It matters in football because 3 points is a field goal and the most common NFL margin, so the extra half-point turns a push at +3 into a win at +3.5.
What does a negative spread mean?
A negative spread marks the favorite and shows how many points that team must win by. A team at -7 must win by 8 or more. Winning by exactly 7 is a push and the stake is refunded.
What does a +8.5 point spread mean?
+8.5 means the underdog can lose by up to 8 points and still cover. The bet loses only if the margin reaches 9 or more. In the NFL it sits just above two scores, since a team down 8 can tie with a touchdown and a two-point conversion.
What does cover the spread mean?
Covering the spread means beating the number the sportsbook set. A favorite at -3 covers by winning by 4 or more. An underdog at +3 covers by winning outright or losing by 1 or 2 points.
What happens if the score lands exactly on the spread?
That is a push. No one wins or loses and your original stake is refunded. Pushes are only possible on whole-number spreads; a spread ending in .5 always produces a clear result.
What does -110 mean next to the spread?
-110 means you risk $110 to win $100. The extra $10 is the sportsbook’s commission, known as the vig or juice. At -110 pricing you need to win about 52.4% of your spread bets to break even.
