Mii limits in both games
| Limit | Living the Dream | 3DS game |
|---|---|---|

| Miis in one home | Up to 8 in a shared house | One per apartment; married couples also get a house |
| Islands | One per console user | One per copy of the game |
| Free demo | 3 Miis, and the save carries over | None: free 3DS eShop downloads ended in 2023 |
| Console's own Mii list | 100, separate from the island | Separate Mii Maker app |
Living the Dream: 70 residents
Nintendo's FAQ puts it in one line: a player can register up to 70 Miis. Every resident counts, including a couple's child who stays on the island. Once the island is full, someone has to leave before a new Mii or a grown-up child can move in.
The Mii count also drives the island itself:
| Miis | What happens | Max size |
|---|---|---|
| 6 | Island Builder unlocks | 50 x 36 |
| 8 | First expansion | 70 x 50 |
| 20 | Second expansion | 90 x 64 |
| 35 | Final expansion | 120 x 80 |
These figures are from Animal Crossing World's guide, which also found that the island does not shrink when you delete Miis. Some players add placeholder Miis to reach 35 early and replace them later.
The cap has not moved since launch. Nintendo's update notes for versions 1.0.1 to 1.0.4 list bug fixes and one Local Play change.
Tomodachi Life (3DS): 100 residents
The game's manual says up to 100 Miis can live on your island. They live in the Mii Apartments, which the Tomodachi Life wiki records as growing in three steps:
- 20 islanders: 48 apartments
- 45 islanders: 72 apartments
- 70 islanders: 100 apartments
A baby being raised at home doesn't take an apartment. When the child grows up you choose between an apartment and life as a traveler. If the island is full, you have to delete a Mii first or send the child traveling. Travelers who arrive by StreetPass stay at the port and campground and can't become residents.

What to do when the island is full
- Remove a resident. In Living the Dream, pick the Mii in the Residents list, open its edit screen and choose the delete option. The game charges a moving fee ($33 in the US version), nothing is refunded, it can't be undone, and the last resident can't be deleted. On 3DS, delete from the Mii List at the Town Hall. Your look-alike and Miis raising a baby can't be deleted there.
- Save the look first. A Living the Dream Mii can't be copied back to the console, so note its settings if you may want it again. On 3DS, make a QR code or copy the Mii to Mii Maker before deleting.
- Start a second island. On Switch, save data and islands are created separately for each console user, so another user profile gets its own 70. A 3DS copy holds one save.
Planning a big cast? The Mii ideas page has themed sets sized to fit, and Mii sharing explains how to bring Miis in from a friend. The main Mii guide covers the rest.
FAQ
Can you have more than 70 Miis in Tomodachi Life: Living the Dream?
Not on one island. 70 is the limit in Nintendo's FAQ, and no update up to version 1.0.4 has changed it. A second user profile on the same console has its own island with another 70.
Do babies count toward the Mii limit?
In Living the Dream, a child who stays becomes a resident and needs a free slot. On 3DS, a baby being raised at home doesn't count; it needs a free apartment only when it grows up and stays.
How many Miis do I need for the biggest island?
35. Living the Dream unlocks the Island Builder at 6 Miis and expands the island at 8, 20 and 35. Deleting Miis afterwards does not shrink it.
How many Miis can the Switch itself store?
Up to 100 in System Settings > Mii, according to Nintendo. That list is separate from the 70 residents on a Tomodachi Life island.
