Reading a point spread takes about five seconds once the sign convention clicks. The team with a negative number is the favorite; the team with a positive number is the underdog. That's the whole framework.
What do the minus and plus signs actually mean?
Say the line reads Chiefs -6.5 / Raiders +6.5. The Chiefs must win by 7 or more for a bet on them to cash. The Raiders can lose by up to 6 points — or win outright — and still cover. The number tells you the required margin, nothing else. For a deeper background on the concept itself, see What Is the Point Spread? A Plain-English Explanation.
How does the half-point work?
Half-points eliminate ties. A spread of -6.5 means the favorite must win by at least 7 whole points. There's no way to land exactly on 6.5, so a push is impossible. Whole-number spreads like -7 can produce a push when the margin hits exactly 7. Learn what happens in that scenario at Cover and Push: What Happens When the Margin Hits the Number.
What does the price next to the spread mean?
Most spread lines show -110 on both sides. That's the vig — the sportsbook's built-in commission. At -110 you wager $110 to profit $100. It's not the spread number; it's the cost to play. The full breakdown lives at How -110 Odds Work: The Vig Behind Every Spread Bet.
Can I lose more than my bet?
No. A straight spread bet is a fixed-risk wager — your maximum loss is the amount you wagered. There's no way to go negative on a single spread bet at a licensed sportsbook.
Can I bet spreads on my phone?
In any state where mobile sports betting is legal — more than 30 states as of 2024 — yes, provided you are physically located inside that state when placing the bet. Geolocation software confirms your position. States like Utah, Hawaii, California, and Texas have no legal market, so mobile betting is not available there regardless of where your account was created.
| Reading the Line | Example | What Must Happen to Win |
|---|---|---|
| Favorite (negative) | Chiefs -6.5 | Chiefs win by 7 or more |
| Underdog (positive) | Raiders +6.5 | Raiders lose by 6 or fewer, or win outright |
| Standard price | -110 both sides | Wager $110 to profit $100 |
