Balanced Stack Sizes
Balanced Stack Sizes allows configurable changes to the maximum stack size of items. This mod will not change anything by default - you must set the config (see below).
A pre-made config file is available to download alongside each version which affects various bulk items, and items whose stack size is too small. This configuration aims to increase stack sizes in a balanced way to combat the inventory space issue.
Configuration
The mod's config is located at balancedstacksizes.json5
stackSizes: A map of item identifiers or tags to their maximum stack size (max 2,147,483,646)
Example Config:
{
"stackSizes": {
"minecraft:dirt": 256,
"#minecraft:planks": 128,
"minecraft:waxed_exposed_cut_copper_stairs": 32
}
}
Entries higher in the list take priority.
Server configuration will be automatically synced to clients when joining a server.
Items with durability can be made stackable, however using the stack will reduce the durability of all items in that stack.
The text size of stacks above 999 will be decreased, however above 999,999 the text will still overflow into the next slot.
