Uses the stack size chosen above.
The formula
Stacks = items divided by stack size, rounded down. The remainder is what is left over. For 1000 items at 64: 1000 / 64 = 15 stacks, and 15 x 64 = 960, so 40 items are left.
A single chest has 27 slots. A double chest has 54. A shulker box has 27. So a single chest holds 27 x 64 = 1728 items of a 64-stack item, and a double chest holds 3456.
Which items stack to 16 or 1
Most blocks and materials stack to 64. Ender pearls, snowballs, eggs, signs, banners and empty buckets stack to 16. Tools, weapons, armour and potions do not stack, so their size is 1.
Common mistakes
- Using 64 for an item that stacks to 16. Pick the right size first.
- Forgetting that a leftover partial stack still takes a whole slot.
- Typing a decimal. The calculator drops anything after the point.
