NBA lines explained: spreads, totals and moneylines

Basketball scores are high and margins swing a lot, so the NBA market is built around points rather than just who wins. Three bet types cover almost everything you will see: the point spread, the total and the moneyline. Once you can read them, an NBA betting page stops looking like a wall of numbers.
The point spread
The spread levels the contest. The favourite is given a minus number and the underdog a plus number.
- Team A -6.5 means Team A must win by 7 or more points for the bet to win.
- Team B +6.5 means Team B can lose by 6 or fewer, or win outright, for the bet to win.
Example: Team A -6.5 wins 112 to 108, a margin of 4. Backing Team A loses, because 4 is less than 6.5. Backing Team B +6.5 wins, even though Team B lost the game. The half point removes any chance of a tie on the bet.
Whole-number spreads and pushes
If the spread is -7 and the favourite wins by exactly 7, the bet is a push and your stake is returned. Pushes only happen on whole numbers. Half-point spreads such as -6.5 cannot push, which is one reason the movement between -6.5 and -7 matters.
Typical pricing: why -110 appears everywhere
American odds of -110 mean you stake 110 to win 100. In decimal that is about 1.91. Spreads and totals in US markets are often priced at -110 on both sides.
The implied probability of -110 is 110 / 210 = 52.4%. Both sides together imply 104.8%, so the bookmaker's margin is about 4.8 points. In practice that means you need to win roughly 52.4% of your spread bets just to break even. Our guide to bookmaker margin and overround explains how that works, and the odds converter turns American prices into decimals and probabilities.
Example: stake 110 at -110. A win returns 210 in total (100 profit plus your stake). A loss costs the full 110. Win half of 100 such bets and you lose about 5 stakes' worth overall, because the losing bets cost more than the winning ones pay.
The total (over/under)
The total is a line for the combined points of both teams. If the total is 226.5, over wins if the teams score 227 or more combined, under wins at 226 or fewer. A total of 226 exactly would be a push on whole-number lines.
Check whether overtime is included. In the NBA it normally is, which means an extra period can push a game over the number. We cover the general idea in our guide to over/under bets.
The moneyline
The moneyline ignores margin of victory. You pick the winner.
- Favourites have negative prices, for example -250: stake 250 to win 100.
- Underdogs have positive prices, for example +210: stake 100 to win 210.
Convert them to see the implied chance. -250 implies 250 / 350 = 71.4%. +210 implies 100 / 310 = 32.3%. The two add to 103.7%, the margin again. Moneylines for big favourites pay little, so the spread is often used to get a better price on the same side.
Key numbers in basketball
In American football, certain final margins are common, so spreads at 3 and 7 are treated carefully. Basketball is more spread out, because scoring comes in ones, twos and threes. Margins of 1 to 10 are all fairly common, with no single dominant number. That makes the half point worth less than in football, but it still has value: a line moving from -6.5 to -7.5 passes through several margins that happen regularly. If you can, take the lower number on a favourite and the higher number on an underdog.
What moves the numbers
Bookmakers adjust lines for information. These factors matter most.
- Injuries and rest. A star player sitting out can move the spread by several points. Check the news close to tip-off, as lines move with each update.
- Back-to-backs. Teams playing on consecutive nights, especially when travelling, tend to perform worse, and the market usually prices that in already.
- Pace. Faster teams create more possessions and higher totals. Two slow teams usually meet at a low number.
- Home court. Home advantage is worth a few points in most models, but it varies from team to team.
- Schedule spots. The end of a long road trip or a game with little at stake can affect effort.
None of these gives you a guaranteed edge, because the market already knows them. Use them to understand why a line sits where it does and to compare prices.

Practical tips
- Confirm the exact line and price before you bet, as spreads move quickly.
- Do not treat a favourite as safe: the NBA has frequent upsets.
- Keep stakes small and consistent. See bankroll management for how to size them.
Key takeaways
The spread backs a team to win or lose by a margin, the total backs combined points, and the moneyline backs the winner outright. A standard -110 price carries about a 4.8 point margin, which is the cost you pay on every bet. Injuries, rest, pace and home court explain line movement, but no factor makes a result certain.
