Choosing the right TV size for a living room nook depends on viewing distance, but generally, a screen between fifty to eighty-four inches works well. For example, one homeowner successfully installed an eighty-four inch TV in their nook without discomfort. The screen should fit comfortably within the recess while keeping the viewing height at seated eye level. Measure your nook width, and ensure wiring supports the size for a neat, immersive entertainment area.
