Point Spread Betting Explained With Real Score Examples

Point spread betting is the most popular way to bet on basketball because it makes almost any matchup interesting, regardless of how uneven the two teams look on paper. Working through a few real score examples makes the mechanics click quickly.

The basic setup

A sportsbook sets a spread to roughly balance a game. The favorite is shown with a minus number, the underdog with a matching plus number. If the Lakers are minus 5.5 against the Pistons, the Pistons are plus 5.5 in the same game.

Example: the favorite covers

Lakers win 112 to 100, a 12 point margin. Since the Lakers were minus 5.5, they needed to win by 6 or more for a spread bet on them to pay out. A 12 point win clears that easily, so the spread bet on the Lakers wins.

Example: the favorite wins but does not cover

Lakers win 105 to 102, a 3 point margin. They won the game outright, but a spread bet on minus 5.5 needed a margin of 6 or more. Since 3 points falls short of that, the spread bet on the Lakers loses, even though they won on the scoreboard.

Example: the underdog covers

Pistons lose 108 to 104, a 4 point margin. A spread bet on the Pistons at plus 5.5 wins as long as they lose by fewer than 5.5 points, or win outright. A 4 point loss covers the spread, so this bet wins despite the Pistons losing the actual game.

Why half points matter

Spreads are often set with a half point, such as 5.5 rather than 6, specifically to avoid ties. A whole number spread, such as minus 6, can result in a push, where the margin lands exactly on the number and stakes are refunded rather than won or lost.

The takeaway

A spread bet is a bet on the margin of victory, not simply who wins. Before betting a spread, picture two or three realistic final scores and check whether they would actually cover the number, rather than just picking the team you expect to win.
