How to Increase Inventory Capacity in Borderlands 4

Increase your inventory capacity by spending SDU Tokens on Backpack and Bank slots in Borderlands 4. Learn all the ways you can increase your inventory space here.

List of Contents

How to Increase Inventory Capacity

Spend SDU Tokens in SDU Menu

Spend SDU Tokens to Increase Slots

Increase the amount of loot you can carry and store by spending SDU Tokens in the SDU Menu. Every time you increase the capacity for an ammo type or storage, its price will increase.

How to Get More SDU Tokens

Which Storage Deck to Upgrade

Backpack Slots for Farming

Increase Backpack Slots for Farming

A generally good first upgrade is increasing your Backpack slots. This will let you carry more gear and weapons, which you sell later or you can test them out for your current build.

Bank Slots for Important Loot

Deposit Items in Bank of Kairos.png

Another space where you can store weapons and gear, especially any special ones, is the Bank of Kairos. Any gear placed here will be shared with the other characters in your account. Use this space to store gear for other potential builds.

All Bank Locations

Increase Ammo Capacity for Gun Type

Increase Ammo Capacity for Guns

You can also increase how much ammo you can carry for each type: pistol, SMG, assault rifle, shotgun, and sniper rifle. They can be upgraded seven times.

List of All Weapons

Lost Loot Machine for Extra Loot

Lost Loot Machine for Extra Loot

The last storage you can upgrade is for the Lost Loot Machine. It will store any loot you did not put in your Backpack. This should be the last capacity to upgrade, since the Backpack and Bank slots are more practical investments.
