To comfortably fit a king size bed, a room should be at least 12 feet by 12 feet (3.65 m x 3.65 m). This allows adequate space for walking around the bed and for other furniture like nightstands and dressers. In tighter rooms, the bed may dominate the space and limit movement or decor options. https://www.impressionsartstore.com/luxury-carved-wood-king-size-bed-frame-with-ornate-headboard-footboard-by-impression-art-store
