SixSeven
by Tokimi
SixSeven raises the item stack size of most items in the game to 67, and leaves tools and armor at their normal limit.
What it does
Stacks that normally hold 64 items, such as dirt and cobblestone, hold 67 instead. Tools and armor still do not stack. The mod is a single-purpose change to stack limits and nothing else, so no new blocks, menus or commands are added. A server running it needs every connecting player to have it too. Fabric is the only loader it is published for, covering game versions 1.20 – 1.21.10 across 16 release versions.
The mod is released under All rights reserved, so the code cannot be reused under an open license. Files exist for every version in the range, with 0.1 for 1.21.10 as the latest build, published on 2025-12-04.
Key features
Larger stacks
Most stackable items hold 67 per slot instead of the usual 64.
Tools and armor unchanged
Tools and armor keep their single-item limit, so equipment behaves as in vanilla.
Single change
The mod only alters stack sizes and adds no other content, interface or command.

What the author says
That’s it. That’s literally the entire mod. You can now hold 67 dirt instead of 64 dirt. 67 cobblestone. 67 whatever. If it stacks more than 1, it stacks to 67. Tools and armor still don’t stack. But everything else? 67.
