Start with the feet or pedestal of the television, not the diagonal screen measurement. A screen can be wider than its stand, and the stand must fit safely on the usable top. The Alton Media Console is one model to compare against the dimensions of the components you plan to keep together.
How do you size a media console for the equipment you own?
Measure the receiver or game console with its plugs connected. That extra depth matters behind a closed door, and electronics need the ventilation specified by their manufacturer. If the television is mounted on the wall, tape out both its position and the top of the console below it to judge the gap from your usual seat. For display pieces rather than equipment, browse living room cabinets with the contents in mind.
