Guide: How A 5 Star Island Rating Is Exactly Calculated In Animal Crossing: New Horizons

The official Animal Crossing: New Horizons guidebook has revealed the exact requirements to achieve a 5 star island rating in the game.

In order to achieve a 5 star rating, your island must have at least 665 Development points and at least 450 Scenery points.

To earn Scenery points, you must grow as many trees as possible (1 point is awarded for every fully grown tree, up to 190 points). There will be a penalty if you have over 220 trees in your island. For every adult flower on your island, you will earn 1 point. That would mean the easiest ways to hit 450 Scenery points is by planting 190 trees and 260 flowers.

To earn Development points, you have to develop your island in a couple of ways. The easiest ways are as follows:

  1. Build the museum to get 15 points
  2. Upgrade Nook’s Cranny to get 15 points
  3. Build Able Sisters’ tailor shop to get 15 points
  4. For every bridge and incline that’s built, you earn 15 points. That’s a cool 240 points if you max out your bridge (8) and incline (8) limits.
  5. You get points for placing DIY furniture and Nook Shopping furniture
  6. You get 0.2 points per fence placed
  7. You get bonuses for placing furniture that’s worth at least 2000 bells and furniture that’s meant for the outdoors.

Negative Conditions

Clutter

  • Clutter is gauged in the same 8×8 tile divisions as furniture

  • If 45/64 or more tiles are covered in the block, the block is considered cluttered

  • Buildings, bridges, buried items, rocks, cliffs, rivers and inclines will not count towards this

Littering

  • If there are more than 15 small items dropped on the ground, your island will be deemed messy

  • Naturally occurring items such as tree branches, stones and star fragments do not count

If either of these conditions are met, your town can not achieve five stars.
