NFL bet lines are the numbers a sportsbook publishes for every wagerable outcome on a game — a point spread, a moneyline, and an over/under total. Once you can read those three numbers, you have the foundation to evaluate almost any NFL wager before you risk a dollar.
What Does a Full NFL Betting Line Actually Look Like?
A typical board entry shows something like this: Kansas City Chiefs -6.5 (-110) / Philadelphia Eagles +6.5 (-110), Total 48.5 (O -110 / U -110), Moneyline: Chiefs -280 / Eagles +230. Each piece carries a distinct meaning, and I'll walk through them one at a time.
How Do I Read the Point Spread?
The spread is the number after the team name. A negative figure marks the favorite — Kansas City at -6.5 must win by seven or more points for a spread bet on them to cash. A positive figure marks the underdog — Philadelphia at +6.5 wins the bet if the Eagles lose by six or fewer, or win outright. When the favorite wins by exactly the spread number (possible only on whole-number spreads), all bets push and stakes are refunded.
The half-point you see on most spreads — that ".5" — is called a hook, and it exists to eliminate pushes. How a hook interacts with NFL key numbers like 3 and 7 is one of the most important concepts for anyone buying or selling a half-point.
What Does the Moneyline Tell Me?
The moneyline removes the spread entirely — you simply pick the winner. American odds use a $100 baseline: a negative number (e.g., -280) is the amount you must stake to profit $100; a positive number (e.g., +230) is the profit you earn on a $100 bet. So backing the Chiefs at -280 means risking $280 to net $100, while backing the Eagles at +230 earns $230 on a $100 stake.
If you want to compare American odds to decimal or fractional formats used on some international-facing sportsbooks, the guide to American vs. decimal vs. fractional odds in NFL betting breaks down the conversion math.
How Does the Over/Under Work?
The total (or over/under) is the sportsbook's projected combined score for both teams. A line of 48.5 means you bet whether the final combined score lands above or below that number. Like the spread, each side is typically priced at -110, meaning you stake $110 to win $100. That -110 pricing on both sides is how sportsbooks build in their margin — at that price, you need to win roughly 52.4% of bets just to break even. The vig explained: why -110 means you must win 52.4% to break even covers exactly why that threshold matters before you place a bet.
Why Do Lines Differ Across Sportsbooks?
Each operator sets lines independently, and the same game can carry a different spread at DraftKings than at FanDuel. Even a half-point difference on a number near 3 or 7 can have real dollar impact over a season. Comparing NFL bet lines across DraftKings, FanDuel, and BetMGM shows a practical method for finding the best number before kickoff.
Lines also shift from the moment they open to game time, driven by betting volume, injury reports, and sharp-money signals. For a fuller picture of why a spread moves, see what drives NFL line movement from open to kickoff.
Is NFL Betting Legal Where I Am?
Online sports betting is legal in more than 30 states, including New Jersey, Pennsylvania, Michigan, Colorado, Illinois, and others; it remains prohibited in California, Texas, and several other states. You must be physically located in a legal state at the moment you wager — sportsbooks verify this via geolocation. Minimum age is 21 in most states, though 18 is permitted in a handful including Kentucky and New Hampshire. Check legal NFL betting by state for your specific jurisdiction. Must be 21+ (18+ in some states). Gambling problem? Call 1-800-GAMBLER.
