Increasing stack sizes allows players to carry more items in a single inventory slot, reducing inventory management and making gameplay smoother. Using the Stack Size Controller plugin, you can customise stack sizes for different item categories.
This guide requires uMod to be installed on your server. See How to Install uMod (Oxide) on Your Rust Server for instructions.

Understanding the Config Options
The Stack Size Controller plugin uses multipliers to increase stack sizes from their default values.
Multiplier Values
| Value | Effect |
|---|---|
1 | Default stack size |
2 | Double the default stack size |
5 | 5x the default stack size |
10 | 10x the default stack size |
Category Settings
| Setting | Description |
|---|---|
Ammunition | Stack size for ammo (bullets, arrows, etc.) |
Construction | Stack size for building materials |
Items | Stack size for general items |
Medical | Stack size for medical items (syringes, bandages, etc.) |
Weapon | Stack size for weapons |
Tool | Stack size for tools |
Traps | Stack size for traps |
Resources | Stack size for resources (wood, stone, metal, etc.) |
Attire | Stack size for clothing |
Component | Stack size for components |
Food | Stack size for food items |
Example Configurations
Double all stack sizes:
{
"CategoryStackMultipliers": {
"Ammunition": 2,
"Construction": 2,
"Items": 2,
"Medical": 2,
"Resources": 2,
"Food": 2
}
}
10x resources, 5x everything else:
{
"CategoryStackMultipliers": {
"Ammunition": 5,
"Construction": 5,
"Items": 5,
"Medical": 5,
"Resources": 10,
"Food": 5
}
}
Some items like weapons and tools have a default stack size of 1 and cannot be stacked regardless of multiplier settings.
Stack sizes are now configured on your server. Players will be able to carry more items per stack.
