Build logistics / storage planning
Minecraft Stack & Storage Calculator
Convert a material total into full stacks, occupied slots, and the exact number of containers you need. Nothing leaves the browser.

Container slots
Inputs
Describe the storage job
Use the complete build or farm output total.
Keep filter items or other materials in these slots in every direct container. Leave at least one usable slot.

Shulker transport plan
Pack this one material into 27-slot shulker boxes, then carry the boxes. Each filled box takes one transport slot, regardless of the material's stack size.
Keep your tools, food, or other cargo in these slots on every load. This does not reserve space inside the shulker boxes.

Shulker boxes cannot go inside other shulker boxes. Use this plan only for items allowed inside them, not for transporting existing shulker boxes. Each box uses all 27 slots; equipment reservations reduce only the transport slots available on every load.
Storage questions
Capacity without hidden assumptions
Stack size and slot count are separate mechanics. These answers keep the common container shortcuts honest.
How many slots does a double chest have?
A double chest has 54 slots. With items that stack to 64, that is room for 3,456 items when every slot contains the same full stack.
How many items fit in a shulker box?
A shulker box has 27 slots. It can hold 1,728 items that stack to 64, 432 items that stack to 16, or 27 unstackable items.
Why do some Minecraft items stack to 16 or 1?
Stack size is an item property. Many blocks and materials stack to 64, items such as ender pearls commonly stack to 16, and tools, armor, filled shulker boxes, and other equipment are unstackable.
Does this calculator include nested shulker boxes?
The direct result counts the selected container. The separate shulker transport plan packs one eligible material into 27-slot boxes, then counts each filled box as one slot in an inventory, chest, or barrel. Shulker boxes cannot be stored inside other shulker boxes; reserve equipment and filter slots separately.
Count before you craft
Turn a material total into a storage plan
Minecraft storage is easiest to plan in three layers: item count, stack size, and available slots. Keep those values separate so unstackable items and 16-item stacks do not inherit 64-stack assumptions.
Edition & scope note
The arithmetic works for Java and Bedrock, but individual item stack sizes can differ by item, edition, version, or server configuration. Verify unusual items before building a large sorter.
- 01
Enter the item total
Use the complete quantity from your build list, farm output, or sorting plan instead of estimating by chest rows.
- 02
Choose the real stack size
Most blocks stack to 64, several utility items stack to 16, and tools, armor, filled shulker boxes, and other items may stack to one.
- 03
Match the container
Compare occupied slots with the container you will actually use, then leave room for labels, filters, overflow, or mixed materials.
