Did you know a 75-inch television isn't really 75 inches wide? The size is really the diagonal screen measurement from the top left corner of the screen to the bottom right corner of the screen. So – how do you measure your TV properly if you want to place it in a cabinet? First, get out your tape measurer.  You need to measure the horizontal width, vertical height and depth from edge to edge, including the frame around the screen. Start with the depth.  Measure from the front to the back – but don’t include any stand it may be on. Then, move on to the width. Measure horizontally from the outer edges (left to right) Finally, measure vertically, from top to bottom (always including the frame) Check out our TV Measurement Guide If you have any questions, our customer service team will be happy to help you.
