The distance at which TV is viewed in the home is analyzed in terms of the conditions of the surroundings. Newly developed survey method makes it possible to collect a lot of reliable data at a considerably cheaper cost and in a shorter period than in a field survey although based on a questionnaire survey. The results show that the relative viewing distance is around 5 screen heights (H), which is 1 H shorter than before. This change is primarily because the screen size of TVs at home have become bigger despite that the room area has not changed. Absolute viewing distance depends on room area, but screen size does not depend on room area so much. The viewing distance is shorter than the average if the viewer is closely focused on the TV or if interactive services are frequently used.
