Math can show you the way. A good way to judge the perfect viewing distance for the best budget TVs (or their high-end alternatives) is to follow the 30-degree rule. Ultimately, this is subjective, but the Society of Motion Picture and Television Engineers believes you should sit at a distance where your TV's screen takes up a minimum 30-degree field of view when watching general content.

With a 55-inch screen that equates to seven feet four inches, for 75 inches that's ten feet, and with 85-inch TVs you should place yourself around 11 feet four inches away from that colossal panel. The SMPTE also makes a case for the 40-degree rule. If you're looking for a slightly more cinematic or immersive experience, sitting at an angle where the TV fills 40-degrees of your field of view is recommended — that's 1.2 times the diagonal size of the screen.

There is also the 62-degree rule. Are you a fan of cranking your neck as you watch The Odyssey for a fifth time in the front row of an IMAX theater? Then by all means sit a mere 5.9 ft from that 85-inch TV you just picked up. It's important to note that none of this increased science.

C'mon, who actually busts out a measuring tape to calculate precise viewing distances before binging on The Real Housewives of Salt Lake City for 14 hours straight? The dimensions/layout of your lounge are going to play a major role in how close or how far away you view your TV. What are the downsides of sitting too closely to a TV? Many of us grew up with that one elderly relative who would constantly try to give us the heebie-jeebies by stating our pupils would implode if we kept our faces glued to the TV.
