The roulette table layout is the betting map. The inside area covers specific numbers and small groups. The outside area covers larger groups such as red/black, odd/even, high/low, dozens, and columns. Chip position matters. A chip on a number, line, corner, or outside box creates a different bet with a different payout and hit frequency.
Quick Facts
- Inside bets sit on or between numbered boxes.
- Outside bets sit around the number grid.
- A straight-up bet covers one number and pays 35 to 1.
- A split covers two adjacent numbers and pays 17 to 1.
- Dozens and columns cover 12 numbers and pay 2 to 1.
- Red/black, odd/even, and high/low cover 18 numbers and pay 1 to 1.
- The table layout is not the same as the wheel sequence.
Plain Talk
Roulette has two layouts in the player’s mind: the felt layout on the table and the physical order of numbers on the wheel. Beginners often confuse them. The table layout is for placing bets. The wheel layout is for producing the result.
This page is about the felt. For the physical wheel, go to roulette wheel layout. For the full course, start with the roulette guide. For bet prices, read roulette odds and roulette house edge.
The felt is designed to make many bet types visible in a small space. The dealer does not ask every player what they meant. The chip position speaks.
How It Works
The main number grid usually shows 1 through 36 in three vertical columns. The zero area sits at the top or side depending on layout style. Around the grid are outside betting areas.
| Layout area | Bet examples | Numbers covered | Normal payout |
|---|---|---|---|
| Inside numbers | Straight-up | 1 | 35 to 1 |
| Lines between numbers | Split | 2 | 17 to 1 |
| End of row | Street | 3 | 11 to 1 |
| Four-number corner | Corner | 4 | 8 to 1 |
| Two rows | Six-line | 6 | 5 to 1 |
| Outside boxes | Red/black, odd/even, high/low | 18 | 1 to 1 |
| Dozens/columns | 1st 12, 2nd 12, 3rd 12, column | 12 | 2 to 1 |
A chip fully on 23 is not the same as a chip on the line between 23 and 24. A chip at a four-number intersection is not the same as a chip in one number square. This is why neat placement matters.

Roulette Table Example
A beginner wants to bet around number 20 on a European layout. Here is how placement changes the bet:
| Player action | Actual bet | Covered numbers | Payout if it wins |
|---|---|---|---|
| Chip in the middle of 20 | Straight-up 20 | 1 | 35 to 1 |
| Chip on line between 17 and 20 | Split 17/20 | 2 | 17 to 1 |
| Chip on corner touching 16/17/19/20 | Corner | 4 | 8 to 1 |
| Chip at edge of row 19/20/21 | Street | 3 | 11 to 1 |
| Chip on black | Black | 18 | 1 to 1 |
Now suppose the ball lands on 20 black. All five example bets would win if placed. But they would not win the same amount, and they would not have the same chance before the spin.
From the Casino Side:
The table layout is a communication system. It lets the dealer settle dozens or hundreds of small decisions quickly. When placement is clean, the dealer can pay fast. When placement is sloppy, the floor gets involved.
A dealer also watches stack height and bet position. One player may place several chips on one number. Another may place chips close to that number but actually on a split. If the table is crowded, the dealer may ask players to clarify before spinning. After the result, that flexibility disappears.
A floor supervisor wants the layout to be readable from a distance. Surveillance wants it readable from a camera. That is the standard that matters.
Common Mistakes
- Thinking the table number order predicts the wheel order.
- Placing chips between positions and claiming intent after the result.
- Forgetting that columns are vertical on the layout, not on the wheel.
- Betting dozens and thinking zero is included.
- Covering too many inside bets and losing track of total action.
- Assuming outside bets are cheaper because they hit more often.
- Playing racetrack bets without understanding they follow wheel sectors, not felt rows.
Hard Truth
Hard Truth: On a roulette layout, “close enough” is not a betting instruction. A chip position must be clear before the spin, not explained after the ball lands.
FAQ
What is the inside area in roulette?
The inside area is the numbered grid where players make straight-up, split, street, corner, and six-line bets.
What is the outside area in roulette?
The outside area contains larger group bets such as red/black, odd/even, high/low, dozens, and columns.
Does the table layout show the wheel sequence?
No. The table arranges numbers for betting convenience. The wheel uses a different physical sequence.
Are columns the same as dozens?
No. Both cover 12 numbers and pay 2 to 1, but columns are vertical layout groups and dozens are number ranges: 1–12, 13–24, and 25–36.
Does zero belong to any outside bet?
Usually no. Zero is its own green pocket and normally causes outside bets to lose unless a special French rule protects even-money bets.
Can I ask the dealer where to place a bet?
Yes, before betting closes. Do not wait until after the spin to clarify.
What should I learn after the table layout?
Learn inside vs outside bets and then check roulette odds so the layout does not trick you into ignoring probability.
Deeper Insight
The layout creates an illusion of control. Because players can place chips in many exact positions, the game feels more tactical than it is. That tactile feeling is powerful. A player can build a personal map: birthdays, neighbors, favorite corners, a color, a dozen, a “cover” chip on zero. It feels designed.
But every chip still becomes a probability fraction. If your chip covers four numbers on a European wheel, it has 4 favorable pockets out of 37. If it covers 18 numbers, it has 18 favorable pockets out of 37. The layout changes how the bet feels. It does not change how the wheel counts.
This is where the roulette odds calculator is useful. It strips the felt back to covered pockets, payout, and house edge.
Formula / Calculation
$$P(event) = \frac{favorable\ pockets}{total\ pockets}$$
A corner bet on European roulette covers 4 pockets:
$$P(corner) = \frac{4}{37} = 10.81%$$
A red bet covers 18 pockets:
$$P(red) = \frac{18}{37} = 48.65%$$
Formula Explanation in Plain English
The table layout tells you where to put the chip. The formula tells you how many pockets that chip really owns. More covered pockets means more frequent hits, not a better long-term price.
