An NFL point spread bet is settled on the margin, not the winner. The favorite must win by more than the posted number. The underdog covers by losing by less than the number or by winning outright.
That is how DraftKings' market rules grade the bet. A final margin that lands exactly on a whole-number spread is a push, and the stake is refunded.
The steps below run from reading a spread on the screen to a graded first ticket. The key numbers 3 and 7 are explained along the way.
Margin, not the winner
The point spread is a handicap a sportsbook places on a game. Hard Rock Bet's point spread guide describes it as betting on "how much a team will win or lose by."
The favorite carries a minus number, and backing it is called laying points. The underdog carries a plus number, and backing it is called taking points, according to a BestOdds.com guide to DraftKings.
A bet that beats the spread has covered. A push is a final margin that exactly matches a whole-number spread, and it returns the stake.
CBS Sports listed the Ravens at -11.5 over the Titans for Week 4 of the 2026 season, the widest spread of the week. Baltimore covers only with a win by 12 or more. Tennessee +11.5 covers with a loss by 11 or fewer, or with a win.
The half point is called the hook. No NFL game can end on a half point, so a spread such as -3.5 cannot push, DraftKings' rules say.
Most NFL spreads are priced at -110 on both sides, meaning $110 is risked to win $100, according to Covers.com. The extra $10 is the vig, or juice, which is the sportsbook's margin.
Covers.com's example is a book that takes $110 on each side, holding $220. It pays the winner $210, stake included, and keeps $10 whatever the result.
Why 3 and 7 carry extra weight
A key number is a final margin that NFL games land on more often than others. Sports Betting Dime names 3 and 7 as the most important, because games often end on a field goal or on a touchdown plus the extra point.
Covers.com lists the key thresholds as 2.5, 3, 3.5, 6, 6.5, 7 and 7.5. BettingNews.com adds 10, a touchdown plus a field goal, and 14, two touchdowns.
The effect sits in the half point on either side of the key number. A 3-point win wins a bet on the favorite at -2.5. The same win is a push at -3 and a loss at -3.5.
BettingNews.com calls the gap between -2.5 and -3 especially significant, because many games finish by exactly 3.
What a first bet requires
Three things are needed. The first is an account at a licensed sportsbook in a state where online betting is legal. The second is a deposit. The third is a fixed stake decided before the game is chosen.
Hard Rock Bet lists the sequence as creating an account, depositing funds, selecting a game, choosing a side, entering a stake and submitting the wager.
The cost of a spread bet is the stake. At -110, a bettor who wins one bet and loses one bet of $110 each is down $10.
Sports Betting Dime recommends betting 1% to 2% of a bankroll per bet. On a hypothetical $500 bankroll, that is $5 to $10 a bet.
An account at a second sportsbook is optional. It allows the same game to be checked at two numbers, which matters around 3 and 7. The sources do not give account approval or deposit times.
Placing a first NFL spread bet, step by step
From the board to a graded ticket
-
Find the game's spread market
Each team appears with a number and a price. CBS Sports listed Lions -3.5 over Panthers for Week 4 of 2026, and Covers.com listed the same opening number. The step has worked when both teams show the same number with opposite signs.
-
Identify the favorite and the underdog
The minus side is the favorite. Lions -3.5 needs a Detroit win by 4 or more. Panthers +3.5 covers with a loss by 3 or fewer or with a win. The step has worked when every possible final margin can be sorted into a cover or a loss for the chosen side.
-
Check for a hook and for 3 and 7
A whole number can push and a half number cannot. A line of 2.5, 3.5, 6.5 or 7.5 sits on one side of a key number. The step has worked when it is clear what a 3-point or 7-point result does to the bet.
-
Read the price
The standard price is -110. TheGameDay.com puts the usual range on spreads at +100 to -120. A price beyond that range means the side costs more than standard.
-
Compare the number at a second book (optional)
Covers.com notes that +3.5 on an underdog beats +3. The step has worked when the better of the two numbers, at a similar price, has been chosen.
-
Choose the side and enter the stake
Enter the stake set in advance. Before submitting, the slip should list the team, spread and price that were selected. A different number on the slip means the line moved.
-
Submit, then check the grade after the game
The ticket settles on the final score. Overtime is included at DraftKings, and most books state that all bets include overtime unless otherwise stated. The step has worked when the ticket shows won, lost or push.
Grading three hypothetical results
BettingNews.com grades a table of results against two spreads: Chiefs -6.5 against the Raiders, and Bills -3 against the Jets.
| Chiefs -6.5, final 31-21 (margin 10) | Chiefs cover; Raiders +6.5 loses |
|---|---|
| Chiefs -6.5, final 24-20 (margin 4) | Chiefs win the game but do not cover; Raiders +6.5 wins |
| Bills -3, final 27-24 (margin 3) | Push; both sides refunded |
The game winner and the bet winner differ in the second row. The third row is the reason a 3 on the board is read differently from a 2.5 or a 3.5.
Where first spread bets go wrong
Reading the spread as a pick of the winner. Covers.com notes that even a 1-point favorite must win by 2 to cover. The sign is a ticket graded as a loss after the chosen team won. The fix is step 2 above: sort every margin before betting.
Paying for the wrong side of 3 or 7. The sign is the same game posted at -3 elsewhere while the ticket reads -3.5. Sports Betting Dime and BettingNews.com both recommend line shopping around these numbers. BettingNews.com says half-point differences add up over a season.
Assuming overtime does not count. Sports Betting Dime reports that the standard wording is "all bets include overtime unless otherwise stated." The same guide names favorites of 3.5 to 6.5 points as the most exposed to overtime swings. The fix is to read the market's rules before betting.
Betting the team and chasing losses. BettingNews.com advises to "bet the number, not the team" and warns against recency bias, which means overreacting to one week's result. Sports Betting Dime advises against chasing losses. The sign is a stake that grows after a loss. The fix is the fixed unit set before the first bet.
After the first ticket: line movement
The next subject is why the number changes. Covers.com marked its Week 4 opening lines as "subject to change."
Hard Rock Bet moved the Steelers from -2.5 to -3 over the Browns by Wednesday morning, ahead of the Thursday, Oct. 1 game, VegasInsider reported. The Steelers drew 61% of spread tickets and 67% of the money.
The move took the Steelers onto the key number 3. A bettor who took -2.5 before the move wins on a 3-point Steelers win. A bettor at -3 pushes on the same result.
Early money has come in on the road favorite Steelers laying the 2.5.
Injury news moves lines further. RotoWire reported that the Cardinals went from +2.5 to -1.5 against the Giants. The move followed New York's loss of quarterback Jaxson Dart to a season-ending knee injury and of edge rusher Brian Burns to a torn ACL.
Covers.com and BettingNews.com both say quarterback injuries cause the largest spread adjustments.
RotoWire also reported the Bills moving from -5.5 to -7 against the Patriots, across the key number 7. The Packers moved from -1.5 to -3.5 against the Buccaneers, through 3, while Tampa Bay +3.5 drew 92% of the money.
The same spreads keep moving after kickoff. BettingNews.com says most online sportsbooks offer live NFL spreads that update throughout the game, the market this blog covers.
Basketball spreads behave differently in the live market, and the NBA point spread guide covers how those lines move.
