About this project
What does Stack size 64 add?
Stack Size 64
Tired of only carrying 16 ender pearls, one shulker box at a time, or a pocketful
of snowballs? **Stack Size 64** raises the max stack size of (almost) every item
in the game to a full **64**.
What it does
- **Everything stacks to 64.** Blocks, food, potions, buckets, snowballs, eggs,
ender pearls, shulker boxes, beds, banners, signs, books, and more — if it
isn't equipment, it stacks to 64. - **Tools and armor are untouched.** Anything with durability — swords, pickaxes,
axes, shovels, hoes, bows, crossbows, tridents, shears, flint and steel, shields,
elytra, and all armor pieces — keeps its normal stack size of **1**.
Why use it?
Fewer inventory trips and more room to build, mine, and automate. Great for
builders, miners, redstoners, and anyone who has ever filled half their inventory
with ender pearls.
How it works
A single lightweight mixin overrides ItemStack#getMaxStackSize. Non-damageable
items report 64; damageable items keep their vanilla value.
- No dependencies, no config, no performance cost.
- Automatically applies to items added by other mods — anything damageable is
left alone.
Compatibility
| Requirement | Version |
|---|---|
| Minecraft | 26.3 |
| Fabric Loader | 0.19.5+ |
| Java | 25 |
Install on **both client and server** for the best experience. Existing stacks in
old worlds keep working — new pickups simply stack to 64.
Notes
- Purely a stack-size change; it does not duplicate items or affect recipes.
- Safe to add or remove from an existing world.
