CALCULATOR.
Choose any Minecraft item, enter the amount you need, and turn a huge build list into exact stacks, slots, shulker boxes, and chests.

Plan the storage before you start the build
Large Minecraft projects are easier when every material has a storage plan. This calculator converts raw quantities into full stacks, remainders, occupied slots, shulker boxes, and double chests. Add multiple materials to see the total inventory footprint of an entire build.
Accurate stack sizes for every item
A stack is not always 64. Ender pearls, eggs, snowballs, and signs stack to 16; tools, armor, boats, beds, shulker boxes, and many other items stack to one. The catalog applies the correct maximum automatically, so storage estimates remain accurate.

Common storage questions
How many stacks are in a shulker box?
A shulker box has 27 inventory slots. It holds 1,728 items that stack to 64, 432 items that stack to 16, or 27 non-stackable items.
How many stacks are in a double chest?
A double chest has 54 slots, equal to two shulker boxes. It holds 3,456 items when every slot contains a full stack of 64.
Does the calculator support items that stack to 16 or 1?
Yes. Every item uses its real Minecraft Java Edition 26.2 maximum stack size, including ender pearls, snowballs, tools, armor, shulker boxes, and other exceptions.
Can I calculate several Minecraft materials at once?
Yes. Add as many different items as you need. The material list totals item counts, occupied inventory slots, shulker boxes, and double chests for the whole project.
