Your television can provide more convenient entertainment when it sits on a turntable that is easily swivelled. This way, if you have a large group of people watching a football game, you can adjust the TV so everyone can see. Turntables are also helpful when you need to hook up new electronic equipment to the back of your TV.
Measure your TV's screen from the top left corner to bottom right corner if you have a standard cathode ray tube (CRT) television. Turntable and swivel products will state which televisions they accommodate based on this measurement. For example, a turntable will say it's designed for a 40-inch television or smaller. Also measure the bottom of your TV from side to side and front to back. Only buy a turntable that is larger than these measurements.
Measure the stand of your flat screen television from side to side and front to back. The turntable only needs to be larger than the stand the TV comes on, not larger or wider than the actual flat screen. Note the weight of your television, and make sure that the turntable accommodates the weight of your television.
Place your turntable on existing furniture or a countertop that is larger than the size of the turntable. You can also purchase stand-alone shelving units that have turntable tops if you prefer not to use existing furniture as a base to display the TV.
