How to Bet the Point Spread
Key takeaways
- The favorite (-7) must win by more than 7 points; the underdog (+7) covers if it loses by fewer than 7 or wins.
- If the favorite wins by exactly 7, the bet is a push and the stake is returned. Half points (-6.5) rule out a push.
- Both sides are usually priced at -110.
The point spread is a handicap that evens out a game. The sportsbook sets a margin; the favorite has to win by more than it, and the underdog covers by losing by less or winning outright. It is the most popular bet in football and basketball.
How a spread works
Say the line is Favorite -7, Underdog +7, both at -110.
| Final margin | Bet on Favorite -7 | Bet on Underdog +7 |
|---|---|---|
| Favorite wins by 10 | Wins | Loses |
| Favorite wins by 7 | Push (stake returned) | Push (stake returned) |
| Favorite wins by 3 | Loses | Wins |
| Underdog wins | Loses | Wins |
A spread with a half point, such as -6.5, cannot end in a push: the favorite either wins by 7 or more, or it does not.
Why spreads are priced -110
When the spread splits the game evenly, both sides get the same price, usually -110: risk $110 to win $100. At that price you need to win 52.4% of your spread bets to break even. Read more in how to read betting odds.
Key numbers in football
NFL games end most often with a margin of 3 or 7 points, a field goal or a touchdown. That is why a move from -2.5 to -3, or from -6.5 to -7, matters more than other half points: it changes whether the most common results win, lose or push.
Spreads in other sports
- Baseball: the run line, usually ±1.5 runs.
- Hockey: the puck line, usually ±1.5 goals.
- Soccer: the Asian handicap, which can use half and quarter goals.
Spread or moneyline?
If you think the favorite wins comfortably, the spread usually pays better than its moneyline. If you think the underdog wins outright, its moneyline pays more than taking the points. Spreads also move during the week, so the number you get can matter as much as the side you pick.
