An oak four-poster bed can tend to be a huge, room-dominating object—so you’ll want to make sure you have the room handy. Four-posters tend to be queen-sized or king-sized beds, so you’ll need your room to be able to accommodate a 60”x80” or 76”x80” bed frame. We’d advise having at least 2-3 feet on either side, and preferably more like 4-5 feet of room to spare at the foot of the bed.
Four-poster beds need more than horizontal space, however; these pieces of furniture require vertical room, too. A typical post on a four-poster bed is 4-5 feet high, on top of a 2-3 foot bed frame. In order to avoid any issues with low-hanging fans or light fixtures, we’ve found it best to put four-posters in rooms with 9-10’ ceilings; however, you’ll need to measure your room to be sure your four-poster will fit.
