Here you’ll learn the factors to consider when to bet in blackjack and some betting strategies you could use.
How To Bet In Blackjack: Factors Involved
Number Of Decks
While most online casinos won’t explicitly tell you how many decks are circulating a blackjack table, it can be helpful if you know.
There can be anywhere from 1 to 8 decks at a blackjack table, and the number of decks changes the house edge and your probability of hitting a natural blackjack.

Additionally, it is harder to predict what card may come next if there are more decks in play, which can throw off your strategy and how much you should bet for your hands.

Your Risk Tolerance
How much can you afford to bet? It is important to consider your blackjack bankroll size and strategy when deciding how much money to bet and when.

You should be comfortable with the amount you’ll bet per hand and the level of risk you’re willing to take.
Card Counting System
If you’re thinking of using a card counting system when playing with a live online dealer, which isn’t inherently illegal at a blackjack table, it’s improbable you’ll be able to pull off the system needed to do it effectively.
You can, however, get a feel for which cards will be coming next by seeing how many “big cards,” “small cards,” and “neutral” cards are shown in a hand.
If you’ve seen many consecutive face cards, the odds are that the next card will be small. This works vice versa with small cards. If you see many neutral cards in a row, you might want to adjust your bet size due to the unknown nature of what might come next.
Blackjack Betting Strategies
Learning and employing some betting systems to your game can help you maximize your profits.
Here are the main types of blackjack betting strategies players can use to know when to bet in blackjack. Make sure you use the one that fits your playstyle the best.
Positive Betting Strategy
A positive betting strategy, also known as positive-progression betting, is a system that takes advantage of your winning streaks.
Once you win a hand, you increase your bet size. You continue this progression until you lose a hand, then return back to your original bet size. You continue to bet your original bet size until you win a hand again.
This system maximizes profits when you’re winning and prevents heavy losses if you go on a losing spree. Some popular methods are the Parlay system and Oscar’s Grinder system.
Negative Betting Strategy
The negative betting strategy is not recommended for beginners as it has some risk, and you may need a big budget to pull it off successfully.
The principle of this system is that you play hands with a consistent bet size until you start losing, at which point you make a massive bet to recoup losses. One popular example of this type of blackjack betting strategy is the Martingale system.
These types of strategies can be prone to tilt and negative emotions, so we recommend beginners stick with flat betting or positive betting strategies.
Flat Betting
Flat betting is what most, if not all, casual players do at the table. They bet the same bet size consistently throughout all hands, no matter the situation.
If they’re on a losing streak, they bet the same. If they’re on a winning streak, they bet the same. While you won’t steamroll your momentum into massive winnings, the same can be said about losses, too.
This is the best betting strategy for blackjack when you’re just starting. As you progress and improve your game, you can start trying other strategies and test which one works best for you and your current bankroll.

Blackjack Overbetting & Underbetting Risks
Overbetting
Draining Your Bankroll
By constantly overbetting, you’re setting yourself up for failure, and you’ll find yourself without a bankroll most of the time. It’s true that if you hit a lucky streak, you’ll have massive wins, but that’s not something that happens all the time.
Temper your bet sizing, and you’ll find more consistent success, and you’ll be able to play for longer!
Missing Opportunities
If you overbet, you might find yourself in a position where you don’t have enough money to make smart plays like doubling down or splitting.
Unlike in real-life casinos, where you can convert cash to chips mid-hand, online casinos don’t have that opportunity. Therefore, if you don’t have the funds for these plays, the hand could go to waste.
Underbetting
Not Maximizing Profits
Underbetting isn’t risky like overbetting, but you could be missing out on potential profits by consistently betting small amounts.
Luckily, there are some betting strategies you can learn to get bigger profits while minimizing risk.
Closing Thoughts
Understanding how to bet in blackjack requires you to consider several factors to mitigate losses and maximize winnings.
Once you’ve considered the blackjack game you’re playing, the risk you can take, and the betting strategy to stick to, you should be on a good road to improve your game and increase winnings.
Now you’ve learned the basic principles to know when to bet in blackjack, you’re ready to go to your favorite online casinos and play! Check out our top recommended sites to play online blackjack or live dealer blackjack for real money.
