From Walkscape Walkthrough

Your character has a base inventory space that is soft capped at 28 slots. One slot consists of a single type of item up to the maximum number of items that a stack can hold for that type of item (Materials = 25 Items/Stack, Consumables = 20 Items/Stack, Crafted Items and Equipment = 10 Items/Stack, etc.). Going over this soft cap incurs penalties for being overencumbered.
