Rooms
A room works when you can move through it without turning sideways, sit down without shouting across the coffee table, and see the TV without craning your neck. None of that is luck. It comes from a short list of dimensions that furniture makers, builders, and designers have relied on for decades.
These guides cover one room at a time: where the numbers come from, which ones you can bend, and which ones you should not. Start with the room you use most.
