Point spread meaning football

In football betting, a point spread is a number set by the bookmaker that gives the favourite a points deficit to overcome and the underdog a points head start, making the contest fairer for betting.

Also called
Line, spread, betting line, ATS (against the spread).23
Applies to
Primarily NFL and college football; used in against-the-spread wagers on game margin.14
Common example
A typical NFL spread is 3 or 3.5 points; bettors often pay 110 units to win 100.43

Key points

  • The favourite gets a negative spread and the underdog a positive spread; bettors win if their side covers the adjusted margin.23
  • If the final margin equals the spread, the result is a push and stakes are refunded.45
  • The spread is designed to balance betting action on both sides, not to predict the exact score.45

Where this term is used
