Mario Kart 8 Deluxe on the original Nintendo Switch supports up to 12 people online, with no more than two players sharing one console. Nintendo Switch Online is required, and two players on the same console cannot use online multiplayer in Handheld Mode. If you mean Mario Kart World on Nintendo Switch 2, the limit is 24 active players; a September 2026 update lets 26 people enter an online room because some can spectate.
At a glance
| Game and system | Online capacity | Players sharing one console | Important distinction |
|---|---|---|---|
| Mario Kart 8 Deluxe — Nintendo Switch | 2–12 players | Up to 2 | Multiple players on one console cannot play online together in Handheld Mode. |
| Mario Kart World — Nintendo Switch 2 | 2–24 active players | Up to 2 | Up to 26 people can join an online room after the September 2026 update, but only 24 can race at once. |
These are game-mode limits published by Nintendo, not a count of how many people are currently online. The answer therefore depends on which Mario Kart game and which Switch system you mean.

How many people can play Mario Kart 8 Deluxe online?
Mario Kart 8 Deluxe supports 2 to 12 players in Online Play. A maximum of two players can share one Nintendo Switch console, so a 12-player race could be arranged across six consoles with two players on each, or across as many as 12 consoles with one player on each. Nintendo’s support instructions describe the mode as “Online Play (2-12 players, up to two per console).” Nintendo’s multiplayer instructions provide that capacity and the console-sharing limit.
Online play requires a paid Nintendo Switch Online membership. Nintendo’s official Mario Kart 8 Deluxe site says members can play Grand Prix, VS Race and Battle modes online and match with up to 12 friends.

Can two people use one Switch in an online Mario Kart 8 Deluxe race?
Yes. Two players can play online from the same console, and both count toward the 12-player total. That means the number of people is not the same as the number of Switch consoles: six consoles can theoretically provide 12 racers when each console has two players.
There is one important hardware-mode restriction. Nintendo says online multiplayer with more than one person using the same console is not available in Handheld Mode. If two people want to race online from one Switch, use a supported docked or tabletop arrangement with separate controllers rather than trying to add a second player while the console is being used as a single handheld device.

The two-player-per-console limit remains in force regardless of how many controllers are connected.
Why does Mario Kart 8 Deluxe sometimes say eight players?
The eight-player figure refers to local wireless multiplayer, not internet-based Online Play. Nintendo lists local wireless as supporting up to eight players, while Online Play supports up to 12. Those are separate modes with different connection methods and different capacity limits.
In practical terms, an eight-player local-wireless session uses nearby Switch consoles communicating with one another. A 12-player online session uses Nintendo’s online service and requires Nintendo Switch Online. Do not use the local-wireless number to answer an online-capacity question, or assume that an eight-player local session leaves four unused online slots.
Which modes can you play online in Mario Kart 8 Deluxe?
Nintendo specifically identifies Grand Prix, VS Race and Battle as online-play options. The 12-player figure is the maximum lobby capacity for the online mode; the number of racers in a particular event can be lower depending on who joins and what the host selects.

Each console’s two-player allowance applies while joining online with that console. For example, one household can bring two players into a VS Race, while another household brings one; the room still counts all three people individually toward the overall limit.

How many people can play Mario Kart World online?
Mario Kart World is a Nintendo Switch 2 game, not an original Nintendo Switch title. Its official product listing gives online play as 2–24 players, with up to two players sharing one console. Nintendo lists the game’s other multiplayer figures separately: single-system play supports 1–4 players and local wireless supports 2–8. Nintendo’s product listing identifies the game as a Switch 2 exclusive and provides those mode capacities.
As with Mario Kart 8 Deluxe, Nintendo Switch Online is required for online play. The 24-player figure means active participants in the game, not necessarily everyone who can be present in the room.
What changed with the 26-person Mario Kart World room update?
Nintendo’s September 2026 update increased the number of people who can join an online or LAN room to 26. It did not increase the number of active racers beyond 24. Nintendo’s update notice explains that up to 26 people can join a room, while up to 24 can join the game itself; the additional places accommodate spectators.

Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →This distinction matters when organizing a large group. A 26-person room can include two people who watch rather than participate in the current race. If all 26 people expect to drive simultaneously, the game will still cap active players at 24. Room occupancy and race participation are therefore different numbers.
Because the update applies to Mario Kart World, it does not change the 12-player online limit in Mario Kart 8 Deluxe. The two games run on different Nintendo systems and have separate multiplayer specifications.
What do you need before starting an online race?
Prepare the following before inviting a large group:
- The correct game: Mario Kart 8 Deluxe for Nintendo Switch, or Mario Kart World for Nintendo Switch 2.
- A compatible console for every household or group station. A single console can contribute up to two online players.
- A controller for each person sharing a console.
- A paid Nintendo Switch Online membership for online play.
- Updated game software, particularly if you want the 26-person room feature in Mario Kart World.
- A plan for who will race and, in a 26-person Mario Kart World room, who will spectate.
Do not count local wireless consoles as online players until you have selected the internet-based mode. The connection type determines which capacity rule applies.

How do you set up the right number of players?
- Identify the game and console. Check whether the group is using Mario Kart 8 Deluxe on Nintendo Switch or Mario Kart World on Nintendo Switch 2. This determines whether the active-player ceiling is 12 or 24.
- Update the software. For Mario Kart World, install the September 2026 update if you need rooms that can hold 25 or 26 people. Without the relevant update, do not assume the expanded room capacity is available.
- Confirm online access. Nintendo requires Nintendo Switch Online for online play. Check membership access before the group begins, since a missing membership prevents that console from using the online mode.
- Assign players to consoles. Put no more than two online players on one console. For Mario Kart 8 Deluxe, six two-player consoles are enough to reach 12 people; for Mario Kart World, 12 two-player consoles are enough to reach 24 active players.
- Use the game’s Online Play option. In Mario Kart 8 Deluxe, Nintendo names Grand Prix, VS Race and Battle as online choices. Select the desired mode and have the other players join the room.
- Check the count before starting. Count people, not just consoles. Two people on one console consume two places, and spectators in a Mario Kart World room consume room slots even though they do not consume active-racer slots.
How many consoles are needed for a full lobby?
The minimum depends on whether each console has one or two players:
| Game | Active-player maximum | Minimum consoles at two players each | Maximum consoles at one player each |
|---|---|---|---|
| Mario Kart 8 Deluxe | 12 | 6 | 12 |
| Mario Kart World | 24 | 12 | 24 |
These figures describe the theoretical maximum. A smaller group can use fewer consoles, and a room does not need to be full to start an online event. For Mario Kart World, 26 people may occupy the updated room, but the minimum-console calculation for active players remains based on 24 racers; spectators do not need an additional racing slot.
What are the most common counting mistakes?
Confusing the game versions: The original Switch’s Mario Kart 8 Deluxe is the 12-player answer. The 24-player answer belongs to Mario Kart World on Switch 2. Nintendo lists Mario Kart World as a Switch 2 exclusive, so it should not be presented as a mode available on the original Switch.
Counting consoles instead of people: A console with two players uses two online places. Twelve consoles do not automatically mean 12 racers if some consoles have two players and others have none.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesMixing online with local wireless: Mario Kart 8 Deluxe supports up to eight players in local wireless, but that is not the online limit. The online ceiling is 12.
Treating room capacity as race capacity: In updated Mario Kart World, 26 people can join a room, but only 24 can participate actively. Two room occupants may be spectators.
Forgetting Handheld Mode’s restriction: Two players sharing one console online in Mario Kart 8 Deluxe cannot use Handheld Mode. Change the console setup before trying to add the second player.

Are these figures a count of current online players?
No. The numbers are maximum capacities for specific multiplayer modes. They do not estimate how many people are playing Nintendo’s games at a given moment, how many users are searching for a match, or how busy the service is.
That distinction is especially important for the phrase “how many people can play.” It asks how many participants a game allows in one session, not how many active users exist worldwide. Nintendo’s published mode limits are the relevant figures for planning a race.
Which answer should you use?
If someone says “Mario Kart on Switch” without naming a game, answer with the original Switch interpretation first: Mario Kart 8 Deluxe supports up to 12 people online, with up to two per console. Add that online multiplayer with multiple players on one console is unavailable in Handheld Mode and that Nintendo Switch Online is required.
Then clarify the newer system: Mario Kart World on Nintendo Switch 2 supports 24 active online players, or 26 people in an updated room when spectators are included. Keeping those versions and room rules separate prevents the common mistake of applying the Switch 2 figure to Mario Kart 8 Deluxe.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How we interpret the player limits
The figures here follow Nintendo’s published mode labels and product specifications. The key criteria are the game and system, whether the session is online or local wireless, the number of people sharing each console, and— for Mario Kart World—the difference between room occupants and active participants. No player-count survey is needed because the question concerns the games’ stated capacity limits.
FAQ
How many Switch consoles are needed if everyone plays alone in Mario Kart 8 Deluxe?
You would need one console per person, so a full 12-player session would use 12 consoles when nobody shares. Sharing changes the minimum to six consoles, provided each of those consoles has two players and the setup is not Handheld Mode.
Can spectators in Mario Kart World replace racers who leave?
A spectator occupies one of the room’s 26 places but is not one of the 24 active players. If a racer leaves, the room may have an open active-player place, but the game’s exact transition behavior depends on how the room and event are managed.

Does Mario Kart World run on the original Nintendo Switch?
Nintendo lists Mario Kart World as a Nintendo Switch 2 exclusive. The 24-player online specification therefore applies to Switch 2 hardware, not to Mario Kart 8 Deluxe on the original Switch.
Can extra controllers increase the online player limit?
No. Controllers let more people play on a permitted shared console, but Nintendo still limits online participation to two people per console. The overall ceiling remains 12 for Mario Kart 8 Deluxe and 24 active players for Mario Kart World.
