The screen size of 28-inch LCD TV is 56.896 cm long and 42.672 cm wide.

The screen size of a 32-inch LCD TV (calculated according to the ratio of 4:3) is 65.024 cm long and 48.768 cm wide.

Generally speaking, a 32-inch LCD TV is suitable for the bedroom. The bigger the TV screen, the greater the viewing distance. This is because the visual angle of human eyes is limited without turning. A reasonable distance requires people to see every corner of the TV picture clearly without turning their eyes and heads. It is generally recommended that the viewing distance is 3-4 times the height of the TV.
