Capacity Reference

1 stack = up to 64 items

1 shulker box = 27 slots × stack = 1,728 items (stack of 64)

1 single chest = 27 slots × stack = 1,728 items

1 double chest = 54 slots × stack = 3,456 items (stack of 64)

1 full shulker of shulkers = 27 × 1,728 = 46,656 items

1 double chest of shulkers = 54 × 1,728 = 93,312 items

How to use the Stack Calculator

Type the total number of items you want to store and choose the stack size: 64 (most blocks and items), 16 (buckets, eggs, potions...), 1 (tools, armor, enchanted items), or a custom value. You can also click an item directly from the list under "Common Items" to apply its stack size automatically.

The results display how many stacks, shulker boxes, single chests, and double chests are required, alongside an estimate of how many "shulkers of shulkers" that total represents. The "Storage Visualization" section breaks down capacity fill rates for each container type, and the "Shulker Inventory" demonstrates how items distribute across a shulker box's 27 slots.

Default capacities in Minecraft

A shulker box and a single chest each contain 27 slots. A double chest contains 54 slots (double). For items stacking up to 64, this equals 1,728 items per shulker/single chest and 3,456 items per double chest. Items with lower stack limits (16 or 1) reduce container capacities proportionally.

Frequently Asked Questions

How many items fit in a shulker box?

A shulker box has 27 slots. For items that stack up to 64, it holds 1,728 items in total.

How many items fit in a double chest?

A double chest has 54 slots. For items that stack up to 64, it holds 3,456 items in total.

Why don't all items follow the 64-per-stack default?

Items like potions, eggs, and buckets stack up to 16 or don't stack at all (stack size of 1), so fewer fit per slot compared to standard items like blocks.
