What “Home (-10.5)” Means in Basketball Sports Betting
When you see Home (-10.5) in basketball betting (often on the point spread), it means:
- The home team must win by more than 10.5 points for your bet to win.
- The away team has a +10.5-point advantage before the game starts (for betting purposes).
So, if the home team wins by 11 points or more, you win.
If they win by 10 points or fewer (or lose), you lose.
Example with a Team
Let’s use an NBA example:
Game:
Boston Celtics (-10.5) vs. Charlotte Hornets (+10.5)
Scenario 1: Celtics win 120–107
- Margin = 13 points
Celtics cover the spread (win by more than 10.5)
Bet on Home (-10.5) wins
Scenario 2: Celtics win 115–108
- Margin = 7 points
Celtics do not cover the spread
Bet on Home (-10.5) loses
Scenario 3: Celtics lose 110–112
- Celtics lose outright
Bet on Home (-10.5) loses
Why Bookmakers Use -10.5
The 0.5 (called a hook) prevents a tie or “push.”
It means there’s no way to get your stake refunded — the result is always a win or loss.
Betting Tip
- Check the matchup and form
Only back Home (-10.5) if the home team is strong offensively and the opponent is weak defensively or missing key players. - Pace and scoring styles matter
Fast-paced teams like the Celtics, Bucks, or Kings can easily cover big spreads because they score in bunches. - Avoid large spreads early in the season
Teams may still be adjusting, making double-digit wins less likely. - Look at 4th-quarter performance
Strong closing teams often “pull away” late, helping you cover big spreads.
Example Betting Tip
If the Boston Celtics (-10.5) are hosting the Charlotte Hornets, and:
- Celtics are averaging 120 PPG at home
- Hornets are allowing 118 PPG on the road
- Jayson Tatum and Jaylen Brown are both playing
Then betting Celtics -10.5 is value, since Boston could easily win by 12–18 points.
Quick Summary
