How to size your bets when counting

Why bet size is the whole game

Counting cards does not tell you which hand to play. The hand decision is fixed by the chart and the deviations. What counting gives you is permission to bet bigger when the shoe is in your favour, and a reason to bet small when it is not. The expected value of a counting session is the sum, hand by hand, of bet size times edge. Edge moves around with the count but is small in absolute terms. Bet size can move by an order of magnitude. The lever that actually makes the math work is the bet ramp.

The 1-2-4-6-8 ramp

The cleanest published ramp for Hi-Lo on a typical six-deck S17 game is one unit at neutral, scaling up roughly to eight units at the top of the count.

• True count ≤ +1: 1 unit.
• True count +2: 2 units.
• True count +3: 4 units.
• True count +4: 6 units.
• True count +5 and above: 8 units.

A unit is the smallest bet you are willing to make at the table. On a fifteen-dollar table, a unit is fifteen dollars and the top of the ramp is one hundred and twenty. On a twenty-five-dollar table, eight units is two hundred. The exact step pattern matters less than the overall spread — the ratio between the biggest and the smallest bet you put out.

A 1-to-8 spread on this game is around the minimum needed to be clearly profitable. A 1-to-12 spread extracts more edge but draws more attention. The pit watches large spreads carefully.

The bet spread calculator prints the ramp in actual dollars once you tell it the table minimum and your top bet, which is faster than memorising the multiplication.

How wide a spread can you actually use

The mathematical answer is "as wide as the bankroll supports". The practical answer is "as wide as the table tolerates". Most pits at low-to-mid limit tables will not pay much attention to a 1-to-4 spread; a 1-to-8 spread starts being interesting; a 1-to-16 spread or more on a low-limit table reads as a counter to anyone watching, and the casino will eventually back you off or shuffle on you.

High-limit rooms tolerate bigger spreads as a percentage of the floor because variance is expected, but they also have more cameras and more experienced pit. There is no universal answer; the local norms of the casino you play at matter more than what you read on a forum. Play conservative until you have a feel for the room.

Risk of ruin

A bet ramp does not produce a smooth profit graph. It produces a series of swings whose net is positive, on average, in the long run. Variance dominates in any session of less than several thousand hands. The bankroll question that matters is: how much money do you need so that a normal losing streak does not bust you?

A reasonable rule of thumb is a starting bankroll of at least 500 units, with 1000 units being safer. That means: if you want a unit of fifty dollars, you should be comfortable with a twenty-five to fifty thousand dollar bankroll dedicated to play. Under-bankrolled counters lose money even when their math is right, because variance wipes them out before the long-run edge catches up. This is the most common way a technically correct counter still goes broke.

What to actually do

Start with a unit small enough that eight units is well within your comfort zone. Drill the ramp until the moves are reflexive. Bet from the count, not from how the last hand went. The hardest discipline at the table is betting the unit on a neutral count right after a big win or a big loss; the count does not care, and the bet should not either. Once the ramp is automatic you can ladder up to bigger units. Trying to play a 1-to-8 spread for real money with a unit you cannot emotionally afford to lose is the second most common way technically correct counters go broke.
