Stack sizes
Most blocks and items stack to 64. Ender pearls, snowballs, eggs, signs, banners, empty buckets and a few others stack to 16. Tools, weapons, armour, potions, filled buckets and shulker boxes don’t stack at all.
Container sizes
A chest, barrel and shulker box each hold 27 stacks, a double chest 54. The player inventory has 36 main slots (armour and offhand slots aren’t counted here). Dispensers and droppers hold 9, hoppers 5.
Shulker boxes keep their items, so a double chest filled with full shulker boxes holds 54 × 27 = 1,458 stacks. That is 93,312 items of a 64-stack item.
