How we calculate it: screen size uses the common viewing-angle guidelines (sitting about 1.2 to 1.6 times the screen size away). Height puts the middle of the screen at your seated eye level, which is the most comfortable for long viewing. Measurements are for standard 16:9 TVs; mount brackets vary, so check your mount's instructions for where the bracket sits relative to the screen's center.
