All About Over/Under Sports Betting

Basics of Over/Under Betting
Over/under betting, also known as totals betting, lets you bet on the total score of a sports game. You don’t pick who wins, but if the total score will be above or below a set number by oddsmakers.
How Over/Under Betting Works
When bookies set a total line at 220.5 points in an NBA game, you can bet:
- Over: Teams must score 221 or more
- Under: Teams must score 220 or less
The number 220.5 stops ties, so every bet has a clear result.
Knowing the Betting Odds
Common odds like -110 show how much you need to bet to get $100. Key parts include:
- High numbers (+150) show gain on a $100 bet

- This helps you know the bet’s worth

What Is Over/Under Betting?
Over/under betting, also known as totals betting, is betting if the total score between two teams will be over or under a set number by oddsmakers.
This betting type focuses only on total points in a game, no matter who wins.
How Over/Under Betting Works

With an over/under bet, bettors look at a number from bookies. For example, in an NBA game with a set total at 220.5, you can bet on:
- Betting over 220.5 points
- Betting under 220.5 points
The half-point stops ties, giving a clear result. If Team A scores 112 and Team B scores 110, the total is 222 points, making the ‘over’ bet win.
Sport-Specific Totals
Different sports have different common betting ranges:
- NFL games: Usually 45-50 points
- MLB games: 7-10 runs common
- NBA games: Often over 200 points
What Changes Over/Under Lines
Oddsmakers look at a lot when setting totals:
- Team attack skills
- Team defense
- Weather
- Old score trends
- Past game results
These factors make precise betting lines that test all bettors.

Getting the Odds Formats for Totals Betting
Knowing how to read over/under odds helps you know possible wins and find good bet chances.
This is a full look at the three main odds types used in betting.
American Odds Format
American odds use plus (+) and minus (-) to show what you might get back.
In totals betting, usual displays include:
- O145.5 (-110)
- U145.5 (-110)
The -110 means you need $110 to win $100. High numbers (+150) show what you earn on a $100 bet.
Decimal Odds Format
Decimal odds make it easy to see what you get back by times-ing it.
A 1.91 decimal price in a market means:
- Bet $100 × 1.91 = $191 total back
- Total has your first bet in it
- Profit is what you get minus what you bet
Fractional Odds Format
Fractional odds, common in the UK, show how much you get vs. how much you bet.
Main points:
- 10/11 odds mean $10 gain for $11 bet
- Change to decimal: divide the first number by the second, then add 1
- Example: 10/11 + 1 = 1.91 in decimal
