A good rule is to sit about one and a half to two and a half times the diagonal screen size away from your TV. For example, with a fifty inch TV, your optimal viewing distance ranges from seven and a half feet to ten and a half feet. This distance balances picture clarity and immersion without straining your eyes. Larger screens require more space, while smaller sets let you sit closer. Adjust based on your room layout and seating comfort, ensuring your TV’s mounting height and distance work together for a relaxed, cinematic experience.
