Description

Increase Stack Size

Raise item stack sizes by default stack-size tier — not by listing every item. Map something like 16=999 and every item that normally stacks to 16 (eggs, snowballs, ender pearls, and more) goes to 999 automatically.

Features

  • Tier-based remapping — configure from=to (example: 16=999, 64=999)
  • No per-item lists — eggs and other 16-stack items are included together
  • Raised vanilla cap — stack / inventory limit increased from 99 up to 999
  • Safe with tools — damageable items (tools, weapons, armor) are never changed
  • Works with modded items that use the same default stack sizes

Configuration Edit config/stacksizes-common.toml (or use an in-game config screen if you have one installed):

stackSizeMappings = ["16=999", "64=999", "8=999"]

Format is "from=to" where from is the item's normal default max stack size.

Important: Changes require a full game restart (quit Minecraft completely, then launch again). Leaving a world is not enough.

Requirements

  • Minecraft 1.21.1
  • NeoForge

Notes

  • Client and server both need the mod for multiplayer
  • Maximum supported stack size is 999
