How to work out stacks

  1. Type how many items you have or need, or switch I have to Stacks. You can also type stacks and items together, such as 39 stacks + 4.
  2. Pick the Stack size: 64 for most blocks, 16 for things like ender pearls and snowballs, 1 for tools and armour.
  3. Read the stacks, inventory slots, chests and shulker boxes it takes.

Storage at a glance

Chest or shulker box 27 1,728 432
Double chest 54 3,456 864
Double chest of full shulker boxes 54 boxes 93,312 23,328

Planning big builds

Large projects use more blocks than people expect. A wall 100 blocks long and 10 high is 1,000 blocks, nearly 16 stacks. A hollow sphere 21 blocks across takes well over 1,000. Work out the total first, then gather in shulker boxes so one trip carries a full box per slot.

When you’re mining or trading for materials, convert the target into stacks here and track progress in stacks rather than single items. It’s much easier to count what’s left in a chest that way.
