📦 Minecraft Stack Calculator
Enter how many items you have to see how many stacks, chests and shulker boxes they fill.
How the minecraft stack calculator works
Minecraft storage is counted in stacks and containers of fixed size: most items stack to 64, some (like ender pearls and signs) to 16, and tools stack to 1. A chest has 27 slots, a double chest 54, and a shulker box 27. This calculator divides your item count by the stack size and by each container's capacity, so you instantly know how many stacks, chests and shulkers you need. It runs in your browser.
A shulker box holds 27 stacks, the same slots as a single chest, but it keeps its contents when broken, which is why it is the unit of choice for sorting and transport. A double chest filled with shulker boxes holds an enormous amount: 54 boxes × 27 stacks × 64 items. Pick the right stack size for your item, as it changes every total.
Frequently asked questions
How many items are in a stack in Minecraft?
Most items stack to 64. Some stack to 16 (ender pearls, snowballs, eggs, signs, honey bottles), and tools, weapons, armour and potions do not stack at all (stack size 1). Choose the matching stack size for an accurate total.
How many items fit in a chest?
A single chest has 27 slots, so 27 × 64 = 1,728 of a normal item. A double chest has 54 slots (3,456 items). A shulker box also has 27 slots. This tool converts any item count into chests and shulkers.
How many stacks are in a shulker box?
A shulker box holds 27 slots, so 27 full stacks, which is 1,728 of a 64-stack item. Shulkers keep their contents when mined, making them the standard unit for storage and transport.
How do I count non-stacking items?
Set the stack size to 1. Tools, armour, potions and similar items each take a full slot, so 27 of them fill a chest and the stack count equals the item count.
