Screen, cabinet and box
This is a measurement method, not a product specification.
Three numbers get collapsed into “TV dimensions” in product listings. They should not.
The screen diagonal is a length across the picture area, or sometimes only a size class near that length. A calculated 16:9 screen has a width and height that follow from that diagonal. Those calculated figures do not include the bezel, and they are not a cabinet size. This site labels them as calculated screen size.
The cabinet, or body, is the outside of the television without assuming a stand. Width, height and depth should come from a specification for that market and that model. A size class shared by several models does not give those outside dimensions. Two 65-inch class sets can differ by inches once the frame and electronics are included.
The assembled set adds a stand configuration. The same model may offer a wide stance and a narrower one, or a soundbar position that changes height and depth. A page that mixes those configurations into one range without saying so is not a measurement.
The carton is packaging. An original retail carton is not a replacement moving box, and a box from another country is not evidence for the US carton. Box dimensions also do not tell you the upright orientation the manufacturer allows.
When a figure is missing, the honest state is that the manufacturer’s page does not list it. A blank, a zero or a typical value copied from another size would all be the wrong substitute.
