What does the spread mean in betting?
The spread — also called the point spread or the line — is the margin of victory a sportsbook expects in a game. It is the most popular bet type in American sports, and understanding it is the difference between betting on a team and betting on a number. You are never just picking who wins; you are picking whether they win by enough.
How a point spread works
The sportsbook gives the favourite a handicap and gives the underdog the same head start. Say the Ravens are -7 against the Browns (+7):
Ravens -7 → must win by 8+ to cover
Browns +7 → covers by winning outright
or losing by 6 or fewer
Final score: Ravens 27, Browns 21
Margin: 6 → Ravens did NOT cover. Browns +7 cash.Notice the Ravens won the game and their bettors still lost. That is the core idea of spread betting: the number, not the result, decides who gets paid. A -7 favourite is being asked to win by a full touchdown — winning by a field goal is a loss at the window.
What the -110 next to it means
The spread is the handicap; the price next to it is what you pay to take either side. A typical board looks like this:
Ravens -7 (-110) bet $110 to win $100 Browns +7 (-110) bet $110 to win $100
That -110 is the vig — the sportsbook's fee. Both sides cost more than the $100 they can win, which is why roughly 52.4% of your spread bets need to win just to break even. We walk through the implied-probability math in our expected value guide.
Pushes and half-points
If the final margin lands exactly on the spread — a 7-point favourite winning by 7 — the bet is a push: it is void and your stake comes back. Nobody wins, nobody loses. Because whole-number lines are common in football, sportsbooks frequently attach a half-point (Ravens -7.5) precisely so a push is impossible and the house keeps its edge on every ticket.
Certain margins come up far more often than others in football — 3 and 7 above all. A move from -3 to -2.5 is worth much more than a move from -6.5 to -6. Serious bettors learn these key numbers before they learn anything else about the spread market.
Spread vs. moneyline
A moneyline bet is simply who wins (we cover it fully in our moneyline guide); a spread bet is by how much. Same game, two different questions:
Moneyline: Ravens to win
Pays whatever the odds say (e.g. -280). Big favourites can cost three or four times your potential profit.
Spread: Ravens -7
Roughly even odds (-110) because the handicap levels the game — but the Ravens must win by 8+ for you to collect.
Underdog spread: Browns +7
Bettors take points with teams they expect to keep it close, even if they expect them to lose.
Three spread-betting traps
- 1
Favourite bias
The public piles onto big names laying big numbers. The spread already charges full price for the favourite — you are paying a premium for a name, not an edge.
- 2
Ignoring the price on the line
Two books can post the same -7 with different prices. -105 versus -115 on identical spreads is real money over a season. The spread gets the headlines; the vig gets your bankroll.
- 3
Betting the spread without your own number
If you cannot say 'I think this game is really -4', you are guessing, not betting. Write your margin estimate first, then compare it to the line — the gap is the only reason to bet.
No spread knowledge guarantees a winning ticket. Spreads are a way to price a game, not to predict one.
