Bet sizing is one of the most critical aspects of sports betting, yet it often gets overlooked by many bettors. Understanding how to size your bets appropriately can significantly enhance your chances of making a profit in the long run. This article provides practical tips on bet sizing, incorporating essential strategies and examples that cater to both novice and experienced bettors.
Understanding Bet Sizing: The Basics

Bet sizing refers to the amount of money you decide to wager on a particular bet. The size of your bets can influence your overall profitability and risk exposure. Here are essential factors to consider when determining your bet size:
Practical Tips for Effective Bet Sizing
To enhance your betting profitability, consider these five effective strategies for bet sizing:
This strategy suggests wagering a fixed percentage of your total bankroll on each bet, typically between 1% to 5%.
Example of Usage:
If your bankroll is $1,000 and you choose to bet 2% of your bankroll, your bet size would be $
The Kelly Criterion is a sophisticated mathematical formula used to determine the ideal bet size based on your edge and the odds offered.
Formula:
\[ \text{Bet Size} = \left( \frac{(bp q)}{b} \right) \times \text{Bankroll} \]
Where:
\( b \) = the odds received on the bet (in decimal)
\( p \) = probability of winning
\( q \) = probability of losing (1 p)
Example of Usage:
If you believe you have a 60% chance (0.6) of winning a bet at odds of 2.0, your calculation would be:
\[ \text{Bet Size} = \left( \frac{(2 * 0.6 0.4)}{2} \right) \times \text{Bankroll} \]
\[ = \left( \frac{(1.2 0.4)}{2} \right) \times \text{Bankroll} \]
\[ = \left( \frac{0.8}{2} \right) \times \text{Bankroll} \]
\[ = 0.4 \times \text{Bankroll} \]
This indicates you should wager 40% of your total bankroll.
Flat betting involves wagering the same amount on every bet, regardless of confidence levels or bankroll changes.
Example of Usage:
If you decide that your flat bet is $50, you will stake this amount for every bet you place. This simplicity can help avoid emotional decisionmaking and maintain discipline.
This technique focuses on identifying situations where the odds offered by bookmakers do not accurately reflect the probability of an outcome occurring.
Example of Usage:
You find a team at +150 odds to win, but after your research, you believe their true odds should be +100 based on various factors, giving you an edge. In this case, you might increase your bet size, wagering more relative to your bankroll as it appears to be a value opportunity.
Regularly evaluate your betting performance to adjust your bet sizes accordingly. If you're on a winning streak, you might consider increasing your bet size slightly while ensuring you remain within manageable risk limits.
Example of Usage:
If your bankroll has increased from $1,000 to $1,300 through successful betting, you might increase your flat bet from $20 to $30 to leverage your improved bankroll while still displaying the discipline needed for longterm success.
