Quick answer: A king in blackjack is worth 10 points, always. The suit never matters. A king of hearts, spades, diamonds, or clubs all count the same. It shares this value with the queen, the jack, and the plain 10 card.
That single fact shapes more of your decisions than most beginners realize. Here is how the king really works, and how to play it well.
How much is a king worth in blackjack?
Ten. Every time.
Blackjack does not carry over the ranking system from poker. In poker, a king beats a queen, which beats a jack. At a blackjack table, that hierarchy disappears. All three face cards sit at the same value.
This trips up new players who come from poker. They assume a king must be “higher.” It is not. For scoring your hand, a king and a jack are identical.
What are all the card values in blackjack?
Blackjack uses a clean three-tier system. Once you learn it, adding up any hand takes a second.
| Card | Value |
|---|---|
| 2 through 10 | Face value (a 7 is 7, a 9 is 9) |
| Jack, Queen, King | 10 points each |
| Ace | 1 or 11, whichever helps more |
The face cards plus the plain 10 form a group known as 10-value cards. There are 16 of them in a single 52-card deck. Four tens, four jacks, four queens, four kings.
Hold that number 16 in your head. It explains almost every smart play in the game.
Why does the king matter so much if it is only worth 10?
Because 10-value cards are the most common card you will see.
Nearly one in three cards in the deck is worth 10. So the safest assumption at the table is that the next card out, including the dealer’s hidden hole card, is a 10.
That assumption drives basic strategy:
- If the dealer shows a weak upcard (4, 5, or 6), assume the hole card is a 10. That gives the dealer a stiff total near 14 to 16, and a strong chance to bust. You can play cautiously.
- If the dealer shows a strong upcard (9, 10, or ace), assume a 10 underneath. Now the dealer is sitting on 19, 20, or a possible blackjack. You need to push your own total higher.
The king does not act alone here. But as one of those 16 ten-value cards, it is part of the math behind every hit and stand.
Is a king and an ace a blackjack?
Yes. King plus ace is a natural blackjack.
An ace paired with any 10-value card on your first two cards gives you 21 with two cards. That is the best possible hand.
A natural usually pays 3 to 2. Bet 10 units and you collect 15. The only way it does not win outright is if the dealer also has a natural, which results in a push (a tie, and you keep your bet).
Two quick cautions:
- A king-ace is a natural. A three-card 21, like 5-6-king, is a good hand but not a natural. It normally pays even money, not 3 to 2.
- Watch the payout on the felt. Some tables pay 6 to 5 on blackjack instead of 3 to 2. That underpays your best hand and quietly raises the house edge. Blackjack communities on Reddit and forums repeat one warning above all others: skip 6-to-5 tables whenever a 3-to-2 game is available.
What do you do with two kings?
You stand. Two kings make 20.
A total of 20 is one of the strongest hands in the game. You beat every dealer hand except a 21.
Some tables let you split two 10-value cards. You almost never should. Splitting a king pair breaks up a near-certain winner into two weaker starting hands. Players do it for excitement, and it usually costs them money over time.
There is a small rule wrinkle worth knowing. Many casinos let you split any two 10-value cards, such as a king and a queen. Others allow a split only when the ranks match exactly. Under that stricter rule, you could split king-king but not king-queen. Either way, the strategy answer is the same: do not do it.
Does the king change in different blackjack games?
The value stays at 10. What changes around it is the mix of cards.
Take Spanish 21. That version removes all four plain 10 cards from every deck. The face cards stay in, so kings, queens, and jacks are still worth 10. But there are fewer 10-value cards overall, which shifts the odds and the correct strategy. The rules add extra bonuses to make up for it.
The lesson: the king’s value is fixed, but the game around it is not. Always check the rule board before you sit down.
Where does the name and the face card even come from?
A short piece of history that most guides skip.
The name “blackjack” traces back to an early version of the game. Some tables paid a bonus for a hand that included the ace of spades and a black jack, meaning the jack of spades or clubs. That bonus faded away, but the name stuck. You do not need an actual black jack to make a blackjack today.
The face cards themselves are old. Kings appear in some of the earliest European decks. Queens replaced an earlier knight figure. The jack, once called the knave, sat below both. None of that lineage affects the modern point value, but it explains why a “king” outranks a “jack” everywhere except the one game where it does not.
Common mistakes players make with kings
- Assuming a king beats a jack. In scoring, they are equal. Both are 10.
- Splitting king pairs. You are trading a 20 for two weaker hands.
- Confusing a natural with any 21. Only a two-card king-ace (or ten-ace) is a natural that pays the bonus.
- Ignoring the payout rule. A king-ace on a 6-to-5 table pays less than it should.
Frequently asked questions
Is a king higher than a queen in blackjack?
No. Both are worth 10 points. There is no ranking between face cards.
How much is a king and a 5 worth?
Fifteen. The king counts as 10, plus the 5.
Can you split kings in blackjack?
Usually yes, but you should not. Two kings make 20, which is a strong standing hand.
Is king-ace the best hand in blackjack?
It is tied for the best. Any 10-value card with an ace on the first two cards is a natural blackjack.
