All placed doors, shown here in their open-left, closed, and open-right configurations.
A Door is a Placeable object, similar to other furniture, with the added benefit of preventing the passage of enemy NPCs while allowing players to easily leave places. It can be placed in any space so long as it is exactly three blocks high, with a ceiling and a floor.
Town NPCs will open and close doors as they wander about. Players can do the same by right-clicking on them. Enemy NPCs will not open doors except for Skeletons, Undead Miners, Goblins, Angry Bones, and Face Monsters. Zombies can also open doors during a Blood Moon, and Goblin Peons can break down doors, as if they were destroyed by a player. Possessed Armor can open doors whether or not a Blood Moon is present.
Doors can be opened and closed through Wires. If you put wire on one of the door's closed-state squares, then wiring will toggle the door's closed/open state upon activation, but if you put wires on the side squares, where the door opens, then wiring will only close the door.
 Noncraftable Doors
- Doors open to the left or right based on which direction you face, rather than the direction you are coming from. For example, if a player stands to the left of a door and faces left, the door will open toward the player - to the left. If the player doesn't move and then turns to the right and opens the door, it will now open to the right.
- Putting a platform or furniture (such as a torch or even a second door) on one side of the door prevents it from being opened in that direction. This is useful to keep houses safe from Zombies during the Blood Moon or most Goblins, as they'll always attempt to open the doors inward, while still allowing NPCs to go in and out as they please.
- Doors can also hold back water.
- Doors (except for Obsidian Doors) will break automatically if exposed to lava while open, but will hold back lava like water while closed.
- Digging a 2*2 block deep hole in front of a door will prevent goblins and zombies from attacking it.
- Dimensions for doors are 2*3 when open, otherwise they are 1*3.
- The Living Wood Door has a sprite similar to the original wood door sprite.
If you open a door while an NPC
is closing it, the door will disappear. the same thing can happen with NPCs or Wiring
instead of a player. Rarely on Mobile
it will drop and reappear again if a NPC passes it duplicating it.
In multiplayer, if the server, or possibly you, is/are lagging, when you open or close a door it will vanish.
If the game lags while you're in a dungeon, there may be a door that's opened on BOTH sides. Trying to close the door will disassemble it.
A closed door that is under water with a wall behind it will show the sky behind the water.
When placing or removing paint on an open door, closing it will revert the changes.
Hooking to the middle of a door with an Ivy Whip
or Grappling Hook
and then opening the door will grant a speed boost, enough to trigger the speed boost from the Hermes Boots
. This can be useful when leaving a house or safe room, as you quickly gain momentum and speed. The direction you will be flung is dependent on which side of the door you're on, not which direction you're facing.
When two torches are placed on the block above the door, they will seem to go slightly up when the door opens, and down to their original position when the door is closed.
