How do I plan the correct TV size and sitting distance in a nook?

Plan TV size and sitting distance in a nook using the rule that sitting distance equals roughly one and a half to two times the diagonal screen size for 4K TVs. For example, a 55-inch screen should be viewed from about six to seven feet away. Use blue tape to outline the TV dimensions on the wall to visualize scale. Measuring seating arrangements before installation ensures comfortable viewing without overwhelming the nook or the room’s flow.
