How many items are in a stack in Minecraft?

A full stack is 64 for most blocks and items. A few items, such as ender pearls, snowballs, eggs, signs and empty buckets, stack to 16. Anything with durability (tools, weapons and armor), potions and filled buckets do not stack at all. Stack sizes are the same on Java and Bedrock.

How much fits in a shulker box, chest or double chest

A shulker box keeps its items when you break it, so a double chest full of shulker boxes holds 54 × 27 = 1,458 stacks: 93,312 blocks. That is the usual way to move a big build's materials.

How to work out stacks by hand

  1. Divide the number of items by 64 and round down: that is your full stacks. 1,000 ÷ 64 = 15.6, so 15 stacks.
  2. Multiply the full stacks by 64 and subtract from the total for the leftover: 1,000 − 960 = 40.
  3. Divide the slots you need (16 here: 15 stacks plus 1 part stack) by 27 for shulker boxes or 54 for double chests, and round up.

Planning a build? The circle generator counts the blocks for circles, spheres and domes, and the pixel art and map art generators list the blocks for an image. Paste any of those totals in here to see how many shulker boxes to fill.
