Reading a Sportsbook Line
Every sportsbook display follows the same conventions; once you learn to read them, you can compare any line at any operator at a glance. Spreads, moneylines, totals, run lines, and puck lines all have specific notation. Here's how to decode every standard sportsbook line you'll see at DraftKings, FanDuel, BetMGM, and the other Ohio operators.
Example
The first number after the team is the spread or total line. The number in parentheses is the price (juice). Bengals -3.5 means Cincinnati must win by 4+. O 47.5 means combined score must exceed 47. Moneyline (ML) means win outright.
When to Use It
- When comparing prices across multiple Ohio sportsbooks; line-shopping is the simplest way to capture edge
- When evaluating live odds; same notation applies, prices update faster
- When reading futures markets; odds-only (no spread/total)
- When checking the bet slip before confirming a wager
Common Pitfalls
- Confusing -3.5 (favorite gives 3.5 points) with -110 (the juice to bet either side)
- Missing the half-point asymmetry; Bengals -3 (push possible) vs -3.5 (no push) matters a lot in NFL
- Not noticing alt-line ladders; sportsbooks offer -7.5 -130, -10.5 +110 etc as alternatives
- Reading run lines / puck lines as spreads; they're always 1.5 in MLB/NHL
When two sportsbooks list the same spread but different juice (e.g., DraftKings -110 vs FanDuel -105), always take the better-priced side if you like the bet. A 5-cent reduction in juice on every wager improves long-term ROI by 2-3 percentage points; meaningful at scale. Use the BettingInOH hold calculator to compare two-way markets and find the lowest-vig book on any given line.
FAQ
What does "-3.5 (-110)" mean?
The team is favored by 3.5 points (must win by 4+). The (-110) is the price; you risk $110 to win $100. The half-point eliminates the chance of a push.
How do I read a run line in MLB?
MLB run lines are always set at 1.5 runs. The favorite is -1.5 (must win by 2+), the underdog is +1.5 (loses by 1 or wins outright). Run lines pay better than moneyline favorites but worse than spread favorites in football/basketball.
What's an "alt line"?
Alternative spread or total. Sportsbooks offer different lines at different prices; e.g., Bengals -3.5 -110 (standard), -6.5 +130, -10.5 +220. Alt lines let you trade probability for payout.
How do I find the best line in Ohio?
Open accounts at 3-5 Ohio sportsbooks (DraftKings, FanDuel, BetMGM, bet365, Caesars). Check the same market on each before betting. The price difference is usually 5-15 cents; small per bet but meaningful long-term.
