Size

Enemy parties in Darkest Dungeon have a limit of 4 combatants, just like heroes. However, enemies come in a variety of different sizes that can occupy more than of of their 4 slots. The list below details what sizes are and what they mean;
 * Small; takes up one enemy slot and does not leave a corpse when it dies.
 * Average; takes up one enemy slot and leaves a corpse that takes up one slot.
 * Large; takes up two enemy slots and leaves a corpses that also takes up two slots. The only exception is the Shambler's corpse which takes a single slot.
 * Gigantic. takes up three enemy slots. Only bosses have this size, and they do not leave corpses when they die.

Note: No matter the size quest bosses do not leave corpses. This includes minion bosses, such as the Brigand Matchman and Drowned Anchorman
