Inside vs outside roulette bets: what's the difference?
Inside bets and outside bets are the two main betting categories in roulette. Inside bets cover individual numbers or small groups of numbers and generally offer larger payouts. Outside bets cover larger groups of numbers, such as colours, number ranges, or odd and even bets, and usually offer lower payouts but wider coverage.
When I first looked at a roulette table, I thought every betting space served the same purpose. Then I realised the layout is split into two distinct areas. One section is packed with numbered betting options, while the other focuses on larger groups of numbers. Suddenly, the table made a lot more sense.
Understanding the difference between inside and outside bets helps explain how roulette payouts work and why players choose different betting approaches. If you're enjoying a game of online roulette, you'll encounter both betting categories almost immediately.
In this guide, I'll break down what inside and outside bets are, how they differ, and why some players prefer one approach over the other.
Inside bets vs outside bets: quick comparison
| Comparison Point | Inside Bets | Outside Bets |
| Numbers Covered | One number or a small group | Large groups of numbers |
| Typical Payouts | Higher | Lower |
| Bet Covers | Specific numbers | Colours, ranges, dozens, columns |
| Coverage | Narrow | Wide |
| Examples | Straight Up, Split, Corner | Red/Black, Odd/Even, Dozens |
The simplest way to think about it is this: inside bets focus on specific numbers, while outside bets focus on larger groups of numbers.
What are inside roulette bets?
Inside bets are wagers placed within the numbered section of the roulette layout. They cover one number or a small group of numbers and generally offer higher payouts than outside bets because fewer numbers are included.
Common types of inside bets
- Straight Up Bet: Covers a single number
- Split Bet: Covers two adjacent numbers
- Street Bet: Covers three numbers in a row
- Corner Bet: Covers four numbers meeting at one corner
- Six Line Bet: Covers six numbers across two adjacent rows
I've always thought of inside bets as the "zoomed-in" side of roulette. You're picking specific numbers or small groups and hoping the ball lands exactly where you've placed your chips. For players who enjoy analysing the table, choosing favourite numbers, or creating their own combinations, inside bets can make every spin feel more personal.
What are outside roulette bets?
Outside bets sit around the outer edges of the betting layout and cover much larger groups of numbers. Instead of picking individual numbers, these wagers focus on outcomes such as colours, ranges, dozens, and columns.
Common types of outside bets
- Red or Black
- Odd or Even
- Low (1–18) or High (19–36)
- First, Second, or Third Dozen
- Column Bets
At almost every online casino, these wagers are among the easiest betting options to spot on the roulette table. Rather than concentrating on one part of the wheel, outside bets spread coverage across a much larger section of the layout. That's one reason they're often popular with newer roulette players.
How do the payouts compare?
One of the biggest differences between inside and outside bets is the relationship between coverage and payout. As a general rule, the fewer numbers covered by a bet, the higher the potential payout. The more numbers covered, the lower the payout tends to be.
| Bet Type | Numbers Covered | Standard Payout |
| Straight Up | 1 | 35:1 |
| Split | 2 | 17:1 |
| Street | 3 | 11:1 |
| Corner | 4 | 8:1 |
| Six Line | 6 | 5:1 |
| Red/Black | 18 | 1:1 |
| Odd/Even | 18 | 1:1 |
| High/Low | 18 | 1:1 |
| Dozens | 12 | 2:1 |
| Columns | 12 | 2:1 |
The pattern is easy to spot. Smaller coverage often comes with larger payouts, while wider coverage is matched with more modest returns.
Are inside or outside bets better?
This is one of the most common roulette questions, and the honest answer is that neither option is objectively better. Inside bets cover fewer numbers and generally offer higher payouts, while outside bets cover larger groups of numbers and usually offer broader coverage. The better choice depends on the type of betting experience you prefer.
Inside bets may appeal to players who:
- Enjoy targeting specific numbers
- Like larger potential payouts
- Want more betting combinations
- Prefer a highly focused approach
Outside bets may appeal to players who:
- Prefer wider number coverage
- Like simpler betting options
- Want quick betting decisions
- Prefer betting on larger groups of numbers
I've seen players sit side by side at the same roulette table and use completely different betting styles. One focuses entirely on individual numbers while the other never places a single inside bet. Both are still playing roulette. They're simply approaching the game differently.
Can you use inside and outside bets together?
Absolutely. Many roulette players combine inside and outside bets during the same spin.
A player could place:
- A Straight Up bet on a favourite number
- A Corner bet covering nearby numbers
- A Red bet covering a much larger group of numbers
That's one of the reasons roulette remains interesting. The betting layout allows countless combinations.
If you're still getting comfortable with the betting board itself, understanding how to play roulette can help put these betting options into context before experimenting with different wager combinations.
Why understanding both bet types matters
You don't need to memorise every payout on the table to enjoy roulette. What matters most is recognising the difference between betting on a small group of numbers and betting on a larger section of the layout.
Once you understand that simple distinction, many parts of the roulette table become easier to interpret. You'll quickly recognise why some wagers offer larger payouts and why others cover much bigger portions of the wheel. More importantly, you'll be able to understand the choices other players make when placing their bets.
The roulette table has room for both
One of my favourite things about roulette is that two people can sit side by side and play completely different games without changing tables.
One player might place chips on a handful of lucky numbers and wait for a bigger payout opportunity. The player next to them might back Red, Odd, and a Dozen bet to cover a much larger area of the table. That's exactly why understanding inside and outside bets matters. They're not competing systems or opposing strategies. They're simply two different ways to interact with the same roulette wheel.
Once you know the difference, the betting layout starts to feel far less intimidating, and every wager on the table begins to make a lot more sense.
