Bag Expansion
February 14, 2026 at 09:40 AM
Added step-by-step unlock instructions, all known expansion costs, and storage tips
You start with 50 inventory slots. Your day-to-day tools take up an entire row, so upgrading the bag is worth doing early. There are eight expansions available, bringing the total to 90 slots.
Open your bag.
Below your existing slots, there is a box next to the word "Expand". Click it.
A pop-up shows the materials needed for the next expansion. If you have them, confirm the expansion.
If you are missing a material, hover over the item in the pop-up and the game tells you how to produce or find it.
Expansion 1 (55 slots): 5x Softwood, 5x Stone, 5x Fiber.
Expansion 2 (60 slots): 5x Carbon Line (Spinning Wheel), 5x Stone Brick (Furnace), 5x Softwood Plank (Cutter).
Expansion 3 (65 slots): 5x Radiant Core (Furnace), 5x Copper Ingot (Furnace), 5x Glass Plane (Cutter).
Expansion 4 (70 slots): 6x Bronze (Furnace), 16x Flour (Separator), 6x Flannel (Loom), 6x Carbon Line (Spinning Wheel).
Expansion 5 (75 slots): 7x Hardwood Plank (Cutter), 7x Iron Sheet (Cutter), 10x Vegetable Juice (Separator), 5x Egg (Chickens or Ducks), 10x Protein Powder (Separator), 10x Fruit Pulp (Separator).
Expansions 6-8 (80-90 slots): Not yet confirmed.
You can turn in materials for Bulletin Board requests and quests directly from your storage. You do not need to carry those items around, which saves bag space. Gifts for NPCs are the exception -- you must have those on your person.
