About this Mod

Triple Inventory

Triple Inventory aims to solve the serious inventory space issues in Minecraft by simply giving you a bigger inventory, along with some quality of life changes.

This mod can add up to 72 new inventory slots, including 18 new hotbar slots - these slots are also accessible in containers.

You can access shulker boxes and ender chests from your inventory by right clicking them - including adding and taking items.

There are also options to automatically switch to the best tool in your hotbar when using an item.

Change the number of available slots with the extendedInventorySize gamerule. This determines how many new inventory columns to add either side of the main inventory. (default 3, max 9, set to 0 to disable extended inventory).
