Stack Size Fix

by chililisoup · on Modrinth

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 26.1–26.2 · Fabric⬇ Download for 1.20.5–1.21.11 · Fabric⬇ Download for 26.1–26.2 · NeoForge⬇ Download for 1.21–1.21.11 · NeoForge
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Makes item counts for items with invalid stack sizes visible.

Useful for playing old worlds on newer versions, where you might have "overstacked" items, but since 1.20.5 you haven't been able to see their actual count when they're not in your inventory.

Also useful on any server that sends invalid item stack sizes, like some Hypixel GUIs.

For shulker boxes specifically, Tweakeroo includes a client-side fix, and Stackable Shulkers Fix contains a server-side fix. If that's all you're after, and you use one of those mods, then this mod is not needed.
