Rule of thumbRecommended
Primary bedroom minimum size
STY-PRIMARY-BEDROOM-01Description
Primary bedrooms in modern homes should be at least 144 sq ft (12'×12') to accommodate a king bed plus walking space.
Why this exists
Primary bedrooms below ~150 sq ft don't fit a king bed plus bedside tables plus a path to the closet. The room reads cramped instead of restful.
