# How to Modify Inventory Stack Sizes for Your Abiotic Factor Server

Learn how to increase how many items can stack in a single inventory slot to optimise storage and gameplay.

**Optimise inventory management by increasing how many items can stack in a single slot on your Abiotic Factor server.**

By default, **Abiotic Factor** limits the number of items that can be stacked in one inventory slot. Increasing stack sizes helps reduce clutter, improve storage efficiency, and make large-scale resource gathering much easier.

### Increasing Item Stack Sizes

You can adjust stack limits by editing the **SandboxSettings.ini** file through your **ChipHead Panel**:

1.  Log in to your **ChipHead Panel**.
