Once you arrive at your Animal Crossing: New Horizons island paradise, there's a lot to master. You need to set up and settle down, know how to craft materials, find the different resources you need, and of course know your neighbors.
You'll start with two other NPCs living on your island with you, and you can help them settle in and set up their tents to get you off to a good start. After a while you may want to have more neighbors and you may wonder how many neighbors you can have in total.
The maximum number of villagers an island can have in the game is 10, so you can try to get a lot more characters to come to your island.
To increase the number of residents from two to five, you will first need to unlock the Museum and Nook's Cranny. As soon as Nook's Cranny is built, Nook will begin his morning address by answering his phone with new residents wishing to join your island paradise. You will be able to get three new villagers to come and live on your island at this point in the game.
Later in the game, you can upgrade Resident Services and get more new plots of land from Nook for 10 Bells each. Remember to think carefully about where you want these new residents to live, as you will be placing their tents for them.
