A field survey and a web questionnaire survey were conducted for obtaining data about television viewing conditions at home. In the field survey, measurements were made concerning the illuminance and luminance of television screens and television viewing distances and angles for 275 viewing locations at 50 homes. In the web questionnaire survey, 290 families were asked about room size, present television screen size, desired television screen size, and viewing conditions. The results showed that the mean screen illuminance was 108lx, and the mean luminance ratio of black and white was 72. The mean viewing distance was 266cm, and the viewingangle range was ±60 degrees from the horizontal, ±30 degrees from the vertical. Correlation analysis of screen sizes revealed that the best predictor of desired television screen size was the present television screen size.
