From back to front I have a folding chair, a dresser and then just enough space for the door to open completely, that's the length. From left to right I have a closet, a strip of free space to walk from one side to the other that's just a little wider than I am and then a bed with the long side against to the wall, and that's the width.
There is a power socket above the chair for two plugs, and another one like that roughly above the feet end of my bed, and we hung up a painting above said power socket. Next to the door are a couple of shelves, and on one of those shelves is my alarm clock. The power cord of my alarm clock is just long enough for it to be able to stay on the shelf with the time being clearly readable.
