Reading Betting Lines: Spreads, Totals, and Moneylines
Sportsbooks offer three main types of bets for most sporting events: point spreads, totals (over/under), and moneylines. Understanding how to read and interpret these lines is fundamental to sports betting success. Each bet type serves different purposes and appeals to different betting strategies.
Point Spreads
Point spreads level the playing field between mismatched teams. The favorite must win by more than the spread, while the underdog can lose by less than the spread (or win outright) for bets to cash.
Reading the Line:
Kansas City Chiefs -7 (-110)
Philadelphia Eagles +7 (-110)
The Chiefs are 7-point favorites. They must win by 8+ points to cover. The Eagles are 7-point underdogs. They can lose by 6 or fewer (or win) to cover. Both bets typically require -110 odds (bet $110 to win $100).
Totals (Over/Under)
Totals bet on the combined score of both teams. You're wagering whether the total points will be over or under the sportsbook's number.
Reading the Line:
Over 48.5 (-110)
Under 48.5 (-110)
If you bet Over 48.5, you need 49+ total points to win. If you bet Under 48.5, you need 48 or fewer total points. The .5 prevents pushes (ties). Standard odds are -110 on both sides.
Moneylines
Moneylines are straight-up winner bets with no spread. Odds adjust to account for the mismatch between teams.
Reading the Line:
Kansas City Chiefs -280
Philadelphia Eagles +240
Chiefs are favorites: Bet $280 to win $100 (or $100 to win $35.71)
Eagles are underdogs: Bet $100 to win $240
Moneylines are perfect when you strongly believe in an underdog or want to back a favorite without covering a spread.
Line Movement
Betting lines move based on betting action and new information. Understanding movement helps you find value:
- Sharp money: Professional bettors' action moves lines significantly
- Public money: Recreational betting volume can create contrarian value
- Injury news: Key player injuries cause immediate line adjustments
- Weather: Outdoor games see line movement based on conditions
- Closing line: The final odds before game start, considered most efficient
Using Lines Strategically
Different bet types suit different situations. Use spreads when both teams are competitive and you have an opinion on margin. Choose moneylines when you're confident in a straight winner, especially for underdogs. Pick totals when you have insight into pace, defense, or game conditions rather than picking a side. Learning to read all three bet types allows you to find the best value for any given opinion.
