Random Room Generator: Type, Size, Condition, One Object and an Exit

Fill the next square of a dungeon map, a floor of an invented house or a scene that needs four walls, with one odd object and a second way out.

An interrogation room, 20 feet square. Water can be heard running behind the walls. In it: a circle of chairs around an empty space. The other way out: iron rungs set into the wall, leading up a shaft.

    Random Room Generator: Type, Size, Condition, One Object and an Exit: how it works

    Each press of this random room generator furnishes one room in five parts: the kind of room, its size and shape in feet, the state it is in, one object worth a second look and the other way out. It fills dungeon maps, floor plans of invented houses and scenes that need somewhere to happen. Every size drops onto a grid of 5-foot squares.

    Lock one row and watch the room change

    Press New room for the first one. Then lock Room on kitchen and press five times to see how much the other rows do. A spotless kitchen with 'a strongbox, open and empty' is a different story from one that 'has been searched recently by someone in a hurry'. Print makes a sheet of 20, enough for one level of a dungeon.

    Why a crypt and a nursery share four rows

    No room type is always tiny or always vast, so any size fits. Conditions cover walls, floor, air and smell, and never say how long the room has stood unused, so 'a table laid for two, the food still warm' never contradicts them. Every exit leads further inside and never to a window, so the room works three levels underground.

    Tips

    • Every object in the full list comes with a question, such as where the bird from the open birdcage went. Answer it before your players or readers ask.
    • The note on each size counts the squares for you: 20 by 30 feet is 4 by 6 squares on a 5-foot grid, or about 6.1 by 9.1 m.
    • Assume you came in by an ordinary door. The fifth row is the way out that somebody wanted, hid or forgot, so decide who still uses it.

    Questions and answers

    How many different rooms are there?

    74 room types times 44 sizes times 46 conditions times 66 objects times 47 exits gives 464,605,152 rooms. Each row runs through its full list before it repeats a line. The room of the day is one room, shown to every visitor.

    Can I build a whole dungeon with it?

    Yes. Deal a room, draw it, then deal the next one at the far end of its exit. Sizes are multiples of 5 feet and no exit leads outdoors, so the map keeps growing. There are no monsters, traps or treasure. Those come from your own game.

    What if the object does not belong in the room?

    That is what the row is for. A wedding dress on a stand in a forge is a question, and the answer is your plot. For ordinary clutter, add things from the random object generator. For the walls around the room, deal a random building.

    How this list was compiled: An original list written for this page. The tool builds one room from five rows (room, size and shape, condition, one notable object, the other way out) and cannot block a combination, so every line in this row was written to read well beside every line in the other four. Rules for this row: a kind of room, lower case, with no article, for a house map or a dungeon map. It lists rooms and never building styles. No room is one that is always tiny (no closets or cells) or always vast (no great halls or ballrooms), so any size in the second row fits. No room needs a window, daylight or a modern machine. The short notes on the older room names are our own wording of standard dictionary definitions. Reviewed line by line for sense, duplicates and agreement with the other four rows on 2026-09-18.

    How this list was compiled: An original list written for this page. The tool builds one room from five rows (room, size and shape, condition, one notable object, the other way out) and cannot block a combination, so every line in this row was written to read well beside every line in the other four. Rules for this row: a short clause about the room itself, meaning its walls, floor, ceiling, air, sound or smell. No condition mentions light, windows, doors or furniture, because other rows own those. No condition says how long ago the room was last used (no dust, no cobwebs, nothing abandoned or stripped bare), so an object such as a table laid for two with the food still warm always fits. Nothing is flooded, collapsed or on fire, so every room can be walked into. Reviewed line by line for sense, duplicates and agreement with the other four rows on 2026-09-18. Licence: own work

    • an arch that has been bricked up, badly A few good kicks would open it again.
    • an iron gate, closed but not locked It squeals. Oil it or accept the noise.
    • an open archway Nothing to close behind you.
    • three steps down to an open doorway Easy to miss in poor light, and easy to trip on.

    How this list was compiled: An original list written for this page. The tool builds one room from five rows (room, size and shape, condition, one notable object, the other way out) and cannot block a combination, so every line in this row was written to read well beside every line in the other four. Rules for this row: a second way out, on the assumption that you came in through an ordinary door. Every exit leads to more building (a door, a stair, a ladder, a hatch, an arch, a crawlway or a hidden door) and never to a window, a balcony or the open air, so it works on an upper floor and three levels underground alike. The note on each exit is what a careful visitor would notice about it. Reviewed line by line for sense, duplicates and agreement with the other four rows on 2026-09-18. Licence: own work
