NBA betting lines explained

NBA games use the same three lines as most US sports, a point spread, a moneyline and a total. The numbers are bigger because basketball is high scoring, but they're read the same way. NBA games can't end in a tie.

Worked example

To start, the box below is filled in with LAL -4.5 -110. In this starting line the Lakers (LAL) are 4.5-point favorites at a price of -110, so they need to win by 5 or more. The box is editable: type any line, or tap one under the card, and the explanation updates.

LAL −4.5: LAL must win by 5 points or more.

What it means

4.5 points are taken off LAL's final score (the favorite gives up points). The other side of this bet is the opponent at +4.5, which wins on any result other than a 5+ point win for LAL.

Watch out for

The spread isn't the price. In LAL −4.5 −110, −4.5 is the points and −110 is the odds. A minus spread means that team is the favorite.

Common lines to try

Lines the NBA uses

  • Point spread: LAL -4.5 means the Lakers have to win by 5 or more. A spread ending in .5 can’t push. More in the point spread guide.
  • Moneyline: LAL -200 / BOS +170 is a bet on who wins. More in the moneyline guide.
  • Total (over/under): O/U 221.5 is about both teams’ points added together. More in the over/under guide.
  • Half and quarter lines: spreads and totals for the first half (1H) or a single quarter (1Q, 2Q…). An NBA quarter is 12 minutes. These lines only count points scored in that part.

What’s unusual about the NBA

Bigger numbers, same reading

Basketball has many more points than football or baseball, so spreads can run past 10 and totals sit well above 200. Nothing else changes. Add the spread to the team’s score and compare, or add both scores together and compare with the total.

Half points and whole numbers

Lakers result LAL −4.5 LAL −5 LAL −5.5
Win by 12 Win Win Win
Win by 6 Win Win Win
Win by 5 Win Push Loss
Win by 4 Loss Loss Loss
Lose by 3 Loss Loss Loss

Overtime, and no ties

If an NBA game is level after four quarters, it goes to a 5-minute overtime, then another if needed, until one team wins. So an NBA game can’t end in a tie, and a moneyline always has a winner.

At most sportsbooks, overtime points count toward full-game spreads, moneylines and totals. Check the house rules for the market you’re reading. Overtime can change a total a lot.

Overtime and the total

Combined score Over 221.5 Under 221.5
216 (108–108 after 48 minutes) Loss Win
234 (119–115 final, after overtime) Win Loss

If overtime counts, the bet is settled on 234, so the over wins.

Lines can move

A spread or total can change between when it’s first posted and tip-off. A line you read earlier, or in a screenshot, may not be the current one.

Mini glossary

  • Tip-off: the start of the game.
  • 1H / 1Q: first-half / first-quarter lines.
  • OT: overtime, 5 minutes per period in the NBA.
  • Team total: an over/under on one team’s points only. The translator reads every total as both teams combined, so use it for full-game totals.
  • Pick’em (pk): a spread of 0.

Common misreadings

Overtime doesn't count, so the total is settled after 48 minutes.
At most sportsbooks overtime points count toward full-game spreads, moneylines and totals. Check the house rules for the market.
A 221.5 total means each team scores about 110.
The total is both teams added together. 130–92 and 111–111 both add up to 222. How it's split doesn't matter.
A double-digit spread must be a typo.
Big spreads are normal in a high-scoring sport. −12.5 just means the favorite has to win by 13 or more.
