Stacks Are Stacks Mod (1.21.8, 1.20.6) – Stack Everything Up to 64 in Minecraft

Minecraft’s default item stacking rules often feel restrictive why carry only 1 water bucket or 16 potions when everything else stacks up to 64? The Stacks Are Stacks Mod (1.21.8, 1.20.6) removes those limitations by allowing nearly every item in the game including typically unstackable ones to be stacked up to 64 per slot. Whether you’re organizing your inventory, prepping for long adventures, or managing resources in modpacks, this lightweight tweak delivers huge quality-of-life improvements without breaking game balance.

Features:

• Stacks all items to 64
  Every item that can logically be stacked including previously restricted items is now stackable up to 64 in a single inventory slot.
• Includes previously unstackable items
  Potions, water and lava buckets, beds, shulker boxes, enchanted books, totems of undying, and even many modded items now follow the 64-item stack rule.
• Maintains vanilla restrictions for tools and armor
  Tools, weapons, and armor pieces remain unstackable to prevent issues with durability and combat balance.
• Compatible with modded items
  Automatically applies stack size increases to most items from other mods no additional configuration needed.
• Great for automation and inventory systems
  Perfect for players who use sorting mods, redstone systems, or massive farms that generate item overflow.

Why use Stacks Are Stacks Mod?

This mod dramatically improves inventory management without changing core gameplay. You can carry 64 potions in a single slot or store beds and buckets more efficiently during travel. It’s especially useful in modpacks, speedruns, and hardcore survival challenges where space matters.

Unlike mods that overhaul inventory systems, Stacks Are Stacks is lightweight, simple, and focuses purely on one enhancement: letting you stack more of what you already collect.

If you’ve ever been frustrated by running out of inventory space too quickly especially when handling modded content—this mod is for you.
