Some items in Minecraft stack upto 64 items in one slot. Some items like potions, stack upto 16, while some others, like tools and weapons, do not stack at all and have a maximum stack size of one. Bigger Stack Size Mod, as the name suggests, allows you to stack all items upto 64. For example, you can have 64 pickaxes in one inventory slot. It is important to keep in mind that the mod is not one-hundred percent perfect ands bugs are to be expected. If a specific item is not stacking, simply drop it on the ground and pick it up again. The item will stack.
