How to Read Betting Lines: A Beginner’s Guide

Betting lines are the language of sportsbooks. Learn Moneyline, Point Spread, and Totals, plus fast examples so you can interpret odds in seconds.

Moneyline Odds: Who Wins?

The Moneyline is the simplest bet: pick the winner. The odds reflect probability and determine payout.

AMERICAN ODDS EXAMPLE

Team A: -200 (Favorite)

Team B: +160 (Underdog)

> -200: Stake $200 to win $100 profit.

> +160: Stake $100 to win $160 profit.

DECIMAL ODDS EXAMPLE

Team A: 1.50

Team B: 2.60

> 1.50: Returns $1.50 total per $1 stake.

Quick rule: favorites have a minus sign in American odds and lower decimal odds. Underdogs have a plus sign and higher decimal odds.

Point Spread: Betting on the Margin

Spreads level the playing field. The favorite gives points, the underdog receives points.

SPREAD EXAMPLE

Team C: -7.5 (-110)

Team D: +7.5 (-110)

> Team C must win by 8 or more.

> Team D can lose by 7 or win outright.

Over Under Totals: Betting on the Score

Totals ask one question: will the combined score be over or under a set number?

TOTALS EXAMPLE

Total: 205.5

Over (-110) / Under (-110)

> Over wins if the score is 206 or more.

> Under wins if the score is 205 or less.

Why Reading Lines Matters

Understanding lines is the entry point to smart betting because it helps you spot value, where odds do not match true probability. Bet Better compares model derived probabilities with bookmaker lines to highlight value betting.
