Make the most of a 9 × 10 ft room
- Push a smaller bed against the wall to free a wider strip for a desk or dresser.
- Keep the main path from the door at 30–36 in if you can.
- Check the way in before ordering: door fit calculator.
Try it yourself: open the room planner with this room and a California King bed already placed, then add a desk or dresser.
