If you are lucky enough to hit a monster hand, you might be wondering: Does a straight flush beat a full house? Yes, a straight flush always beats a full house in standard poker games like Texas Hold’em or Pot Limit Omaha. The straight flush is one of the rarest hands you can make, ranking just below a royal flush, while full houses are much more common. Let’s explore the rankings, probabilities, and why this specific hand matchup creates some of the most dramatic moments in poker.
Straight Flush vs. Full House in Standard Poker Hand Rankings
When you look at the standard poker hierarchy, the winner of the pot is always dictated by the absolute strength of the hand.
The Golden Rule: Being the 2nd strongest hand overall, a Straight Flush will always outrank a Full House, which sits lower as the 4th strongest hand in traditional poker.
To see the massive difference in rarity between the two, here is a quick comparison:
| Hand Type | Example | Probability | Rank |
|---|---|---|---|
| Straight Flush | 9♥-8♥-7♥-6♥-5♥ | 0.0279% | 2rd strongest |
| Full House | Q♥-Q♠-Q♦-6♠-6♦ | 2.60% | 4th strongest |
For a complete overview of what beats what, here is the official poker hand rankings, from strongest to weakest. Click on any hand to learn more about its specific rules:

- Full House

Straight Flush is the 2nd strongest hand in standard hand rankings, while Full House ranks 4th. Therefore, Straight Flush always wins.
Why Does a Straight Flush Beat a Full House?
Poker rankings are based entirely on probability and rarity. The rarer the hand, the stronger it is. Let's look at the exact odds of flopping each of these combinations right out of the gate:
- Straight flush probability on the flop: ~0.00139%
- Full house probability on the flop: ~0.1441%
Straight flushes are over 100 times rarer than full houses on the flop! We can see a similar massive gap in the odds for a full 7-card rundown (by the river):
- Straight flush probability: ~0.0279%
- Full house probability: ~2.60%
Tiebreakers Within the Hands
In the rare case of two players having the same type of hand combination, you need to compare them with each other using standard tiebreaker rules:
- Straight Flush vs Straight Flush: The higher top card wins (e.g., 10s-9s-8s-7s-6s beats 9d-8d-7d-6d-5d). Suits don’t affect rankings in standard poker variations.
- Full House vs Full House: The three-of-a-kind portion decides the winner. If tied, the pair is compared. (Example: K-K-K-2-2 beats 9-9-9-A-A)
In the extremely unlikely event of two players having identical hands (for example, the straight flush is entirely on the community board), the pot is split equally between them.
When Could Rankings Change?
In standard poker formats (like Texas Hold’em, Omaha, or Seven Card Stud), a straight flush always outranks a full house. There are no exceptions.
Even in specific variants like Short-deck Hold’em (36 cards), where hand probabilities shift significantly (for example, flushes outrank full houses in this game), the straight flush remains one of the rarest and strongest hands, safely beating a full house.
Key Takeaways
- The Answer: Does a straight flush beat a full house? Yes, always!
- The Strength: Full houses are incredibly powerful, but they appear often enough to occasionally be beaten by four of a kind or better in huge pots. Still, you should feel very confident playing them.
- The Rarity: Straight flushes, on the other hand, are nearly mythical. Many players can go months without seeing one. When a straight flush beats a full house, it creates an unforgettable poker “cooler” moment.
