How to measure the size of a tv screen
Place the tape measure or measuring stick in the lower left hand corner of the tv's screen.
Be sure to start measuring where the actual screen begins, not from the plastic frame of the tv (known as the bevel).
Extend your tape measure or measuring stick to the upper right hand corner of the tv screen (diagonally from where you started).
Record the length between these two corners. This is the screen's size.
