NFL First Half Lines: How 1H Spreads and Totals Compare to the Full Game
Monday night's Bills at Rams game has two sets of numbers on it. The full game has the Rams -3.5 with a total of 54.5. The first half has the Rams -2.5 with a total of 26.5, as of Sunday night, October 11, 2026. Those first half lines, the ones books label 1H, settle at halftime and ignore everything after it. Here is how to read NFL first half lines, what this week's board looks like, and how 1H numbers compare to the full game across a full Sunday slate.
Bills vs Rams first half lines for Monday Night Football
Every book has the Rams favored in the first half, as of Sunday night, October 11, 2026. Five have them at -2.5 and two at -1.5, and the 1H total is 26.5 everywhere it is posted. If you want Buffalo in the first half, Fanatics and BetRivers give you the extra point at +1.5. Lines move, so check them before you bet, and compare books on our sportsbooks page.
| Book | 1H spread | 1H moneyline (BUF / LAR) | 1H total |
|---|---|---|---|
| BetMGM | LAR -2.5 | +130 / -155 | 26.5 |
| bet365 | LAR -2.5 | +132 / -157 | 26.5 |
| DraftKings | LAR -2.5 | +136 / -162 | 26.5 |
| FanDuel | LAR -2.5 | +126 / -154 | 26.5 |
| Fanatics | LAR -1.5 | +130 / -155 | 26.5 |
| BetRivers | LAR -1.5 | +123 / -152 | 26.5 |
| Caesars | LAR -2.5 | +132 / -159 | Not posted |
The same math we use for full-game predictions works on a half. Take the 26.5 total and the Rams' 2.5-point edge, and the first half implies Rams 14.5, Bills 12. The full-game numbers imply Rams 29, Bills 25.5, so the market expects a little less than half the scoring before the break. With the margin removed, the DraftKings first half moneyline gives the Rams a 59.3% chance to lead at halftime, a bit under their 61.6% chance to win the game.
How NFL first half lines compare to the full game
To see how books build first half numbers, we lined up the pregame full-game and 1H lines for 13 Week 5 games on Sunday, October 11. Each number is the middle of the board across six or seven books on SportsbookReview, and the full-game spreads were checked against the VegasInsider board. Where the middle fell between two numbers, both are shown. The Sunday night game was in progress when we pulled the board, so it is left out.
| Game | Full spread | 1H spread | Full total | 1H total |
|---|---|---|---|---|
| Buccaneers at Cowboys | DAL -9.5 | DAL -6.5 | 49/49.5 | 24.5 |
| Eagles vs Jaguars (London) | JAX -7.5 | JAX -5.5 | 41.5/42 | 21.5 |
| Vikings at Saints | MIN -2.5 | MIN -1.5 | 41.5 | 20.5 |
| Texans at Titans | HOU -6.5 | HOU -3.5 | 37.5 | 18.5 |
| Raiders at Patriots | NE -3.5 | NE -2.5 | 45.5 | 22.5 |
| Giants at Commanders | WAS -3.5 | WAS -2.5 | 41.5 | 20.5 |
| Bears at Packers | CHI -1.5 | CHI -1.5 | 46.5/47 | 22.5 |
| Bengals at Dolphins | CIN -6.5 | CIN -4.5 | 44.5 | 22.5 |
| Colts at Steelers | PIT -2.5 | PIT -1.5 | 41.5/42 | 20.5 |
| Browns at Jets | NYJ -2.5 | NYJ -1.5 | 38.5 | 19.5 |
| Broncos at Chargers | DEN -3.5 | DEN -1.5 | 42 | 20.5 |
| 49ers at Seahawks | SEA -3 | SEA -1.5 | 46.5 | 23.5 |
| Lions at Cardinals | DET -5.5 | DET -3.5 | 55 | 27.5 |
First half totals are almost exactly half
In all 13 games the 1H total landed within one point of half the full-game total, and on average it was 49.7% of it. The Lions and Cardinals had the biggest total at 55, and the first half was 27.5, exactly half. The widest gap was Bears at Packers, where half of the 46.5 to 47 full total is about 23.4 and the 1H total sat at 22.5. If a 1H total at your book is more than a point off half the full total, it is worth a second look at the other books.
First half spreads are closer to two-thirds
This is where people guess wrong. Halving the full-game spread does not give you the 1H number. Across the 13 games, the first half spread averaged about 65% of the full-game spread. Dallas was -9.5 for the game and -6.5 for the half. Cincinnati was -6.5 and -4.5. Seattle came in at exactly half, -3 for the game and -1.5 for the half, and Denver at -3.5 and -1.5 was the only game that came in under half.
Small favorites stop at 1.5
No first half spread in the sample was smaller than 1.5. Every game with a full-game spread of 3.5 or less had a 1H spread of 1.5 or 2.5, and Chicago was -1.5 for both the half and the game. For bettors, that means a short favorite in the first half is usually laying 1.5 or 2.5, not a half point or a pick'em.
How to read an NFL 1H line
A first half spread works like a full-game spread: Rams -2.5 means the Rams need to lead by three or more at halftime. A first half total is over or under the combined points scored in the first and second quarters. A first half moneyline is a bet on who leads at the break. Two things trip people up. First, a tie at halftime is a real possibility, so check how your book handles a tied half on a two-way moneyline; many return the stake as a push, and some also offer a three-way line where the tie is its own outcome. Second, a half-point on the line (2.5 instead of 3) means no push is possible.

When NFL first half lines come out
Full-game NFL lines are usually up well before first half lines. As of Sunday night, October 11, the SportsbookReview board had no first half lines posted for any Week 6 game. Expect 1H spreads and totals to fill in during the week, and expect them to move along with the full-game line. We will update this page with the Week 6 first half board once it posts.
