Datapack Bigger Stack Size

Bigger Stack Size, 64 Items per Stack

Bigger Stack Size is a Minecraft Java Edition datapack that raises the maximum stack size to 64 for items normally limited to one or sixteen, including armor stands, boats, potions, shulker boxes, saddles, and other utility items. Items are updated when they enter your inventory, making resource gathering, building, and storage far more convenient without adding a mod.

Designed for singleplayer worlds and a Minecraft server, it also offers practical control. The stackable item list can be customized, while naming an item “unstackable” with an anvil temporarily prevents stacking, which is useful for sorting systems. At BoxToPlay, we recommend it for survival servers seeking smoother inventory management without changing the core gameplay.
