How to Increase Stack Size in Grounded

One of the most useful quality-of-life improvements in Grounded is increasing your item stack sizes. By default, you can only carry 10 of most items in a single stack, but with the right upgrades, you can significantly expand your carrying capacity. This guide will walk you through exactly how to unlock and maximize your stack sizes for all item types.

Understanding Stack Size Basics

When you first start playing Grounded, your inventory stack limits are quite restrictive. For example, plant fibers—one of the most commonly collected resources—can only stack up to 10 items per stack by default. However, once you know where to look, you can increase these limits considerably to carry 15 or more of the same item in a single stack.

Accessing the Field Station

The key to unlocking stack size upgrades is visiting a Field Station. These stations are scattered throughout the yard and serve as your hub for various upgrades and information. Once you’re at a Field Station, you’ll need to interact with the ASL terminal.

Molar Infusion Upgrades Explained

At the ASL terminal, navigate to the Molar Infusion upgrades menu. These upgrades are unlocked by collecting teeth scattered throughout the yard—specifically white teeth and gold teeth that you’ll find as you explore. Once you’ve gathered enough teeth, you’ll have access to several stack-boosting upgrades.

Types of Stack Size Upgrades

Within the Molar Infusion upgrades, you’ll find a section called “group” that contains three different stack size categories:

• Max Consumable Stack Size – Increases the stack limit for consumable items like bandages and healing items
• Max Resource Stack Size – Boosts the stack limit for crafting materials such as plant fibers, crude rope, and similar resources
• Max Arrow Stack Size – Increases how many arrows you can carry in a single stack

Each upgrade can be leveled multiple times, allowing you to progressively increase your carrying capacity as you collect more teeth throughout your playthrough.

Summary

Increasing stack sizes in Grounded is straightforward once you know the steps. Simply collect white and gold teeth found around the yard, visit a Field Station, access the ASL terminal, and invest in the appropriate Molar Infusion upgrades under the “group” section. Whether you need more consumables, resources, or arrows, there’s an upgrade for every item type in the game. This small quality-of-life improvement makes resource gathering and inventory management much more convenient as you progress.
