Introduction

Point spread betting is a cornerstone of sports wagering, especially in football and basketball. Rather than simply picking a winner, bettors aim to predict how close — or lopsided — a game will be. In this guide, we’ll unpack how spread betting works, what “covering the spread” really means, and how to make smarter wagers using this strategy.

What Exactly Is a Point Spread?

The point spread is a betting tool designed to balance the odds between a favorite and an underdog. Instead of uneven moneyline payouts, the spread allows both sides to carry similar odds — typically around -110 — by introducing a margin that the favorite must win by or the underdog must stay within.

Spread Example: Breaking It Down

Imagine this NFL matchup:

New York Giants -4.5 vs. Chicago Bears +4.5

• If you bet on the Giants -4.5, they need to win by 5 or more points for your bet to cash.
• If you bet on the Bears +4.5, they can lose by 4 or fewer — or win outright — for you to win.

There’s no “tie” here because the spread includes a half point (.5), which prevents pushes.

What Does “Cover the Spread” Mean?

“Covering” the spread refers to a team beating the point margin set by oddsmakers. For example:

• A favorite covers when they win by more than the listed spread.
• An underdog covers when they lose by fewer points than the spread — or win outright.

Bettors aren’t just betting on who wins the game, but by how much or how close it stays.

Why Sportsbooks Use Point Spreads

Sportsbooks use spreads to generate equal action on both sides. By adjusting the line based on public perception, injuries, and other variables, the book tries to minimize its risk and maximize volume. This is why spreads shift leading up to a game — a concept called line movement.

Key Numbers in Spread Betting

In football, certain margins appear more frequently due to scoring patterns:

• 3 points – common due to field goals
• 7 points – a typical touchdown plus extra point
• 10 points – two-score difference

Betting “on” or “off” key numbers can make a long-term impact on your win rate. For example, taking +3.5 instead of +3 gives you coverage on a field-goal loss — a crucial edge.

Smart Tips for Betting Point Spreads

• Track injuries and team news: A missing quarterback can swing a spread by several points.
• Shop for lines: Use multiple sportsbooks to get the most favorable spread possible.
• Watch for reverse line movement: When the line moves against the public money, it may signal sharp bettors backing the other side.
• Bet early or late based on trends: Early lines may offer value before the public piles in.

Common Mistakes to Avoid

• Chasing favorites without analyzing the spread risk
• Ignoring weather or pace-of-play factors
• Assuming a team’s win guarantees they covered
• Failing to check multiple books for better numbers

Conclusion

Understanding the point spread is fundamental to becoming a savvy bettor. It’s not just about who wins — it’s about understanding context, timing, and value. By paying attention to key numbers, line shifts, and situational edges, you’ll put yourself in a stronger position to profit over time.
