Introduction

Whether you’re new to sports betting or looking to sharpen your edge, understanding how to read a betting line is essential. This guide breaks down the three core components: moneyline, spread, and totals — with real-world insights to help you place smarter bets.

What Is a Betting Line?

A betting line is how sportsbooks display the odds and parameters for a specific wager. It shows:

• Who is favored
• The payout odds
• The point spread or projected total

By interpreting a betting line correctly, you’ll understand not only who’s expected to win but also how profitable your bet might be.

Understanding the Moneyline

The moneyline is the simplest form of sports betting — you’re picking a winner.

• A minus sign (-) indicates the favorite.
• A plus sign (+) signals the underdog.

Example:

New York Yankees: -140  
Boston Red Sox: +120

To win $100 on the Yankees, you’d need to bet $140. A $100 bet on the Red Sox would win you $120 if they pull off the upset.

Moneyline bets are great for beginners and used across all major sports — from MLB to UFC.

Point Spread Basics

The spread levels the playing field between teams of varying strength. You’re not just betting on a winner, but by how much they win (or lose).

Example:

Dallas Cowboys -6.5  
New York Giants +6.5

• Cowboys must win by 7+ points to “cover the spread”
• Giants must lose by 6 or fewer, or win outright

If either team “covers,” the bet wins. If the game lands exactly on the spread (e.g. -3.0), the bet is a push and your money is refunded.

Totals (Over/Under) Explained

Also called the over/under, a totals bet asks: Will the combined score be over or under the sportsbook’s projection?

Example:

Over/Under: 44.5  
Final Score: Chiefs 28, Broncos 17 (Total: 45)

In this case, a bet on the Over wins by 0.5 points. Totals betting is popular in football and basketball where scoring is high and variable.

How to Compare Lines Across Sportsbooks

Sportsbooks often differ slightly in their lines. Here’s why comparing matters:

• Moneyline differences: One book might offer +145, another +155
• Spreads may vary: Half-points can mean the difference between a win and a push
• Totals may shift based on sharp betting or injuries

Always line shop to maximize value. Use odds comparison tools or monitor several sportsbooks directly.

Common Mistakes When Reading Lines

• Misreading the spread direction: Remember, a “–” means points are subtracted from the favorite’s score.
• Ignoring juice (vig): Don’t just look at the line — check the odds too.
• Assuming value = outcome: Just because a bet looks “easy” doesn’t mean it’s profitable long term.
• Betting without checking multiple books: Line differences matter more than people think.
