The 2/3's living room rule is a simple proportion guideline: a key element should be about two thirds the size of the element it relates to. Used correctly, it prevents the most common layout problems such as undersized rugs, tiny artwork over large sofas, and furniture groupings that feel visually scattered.
In most areas, a room does not legally have to have a closet to be considered a bedroom. That is a common myth.

Breaking Down the Magic Numbers: The 3-5-7 rule
Arrangements of three, five, or seven items feel more dynamic and natural than even-numbered groupings, which can sometimes look a bit rigid or staged. This principle of decorating with odd numbers is what makes the 3-5-7 rule in decorating so effective.
200 square feet is a small yet versatile area, comparable to the size of a one-car garage or a room measuring approximately 10 feet in width and 20 feet in length. This footprint is ideal for studio apartments, guest rooms, or office spaces, offering sufficient coverage for essential furniture and creative layouts.
“The "Four-Inch Rule" in interior design is a guideline that suggests keeping the seat heights of key furniture pieces, like sofas and chairs, within approximately four inches of each other to create a balanced and visually harmonious seating arrangement.
The closet had two sliding doors that made the space difficult to use from a functional standpoint. By taking them off, not only would it be easier to simply use the closet, but I could also fit my second dresser inside. Like this, it wouldn't take up unnecessary floorspace, and the closet was instantly easier to use.
