How far should I sit from a 55 inch TV?
This gets you the recommended screen diagonal. For example, most people sit about 9 feet (108 inches) from their TV, so THX recommends a screen size of around 90 inches diagonal for that distance. That means the 55-inch you're looking at is not "too big," at least as far as THX is concerned.

- Most sofa seating heights are close to 18 inches above the floor, and eye level for an adult seated in a relaxed manner is about 24 inches above the seat. That puts the optimum, center-of-television height for a typical seated viewer at 42 inches (18 inches + 24 inches).
- Thankfully for TV manufacturers around the world, consumers have an appetite for larger TV screens. While the average screen size for tube TVs used to be around 28 inch, flat-panel TVs started off with an average size of 32 inches and became bigger and bigger over the years.
- All of our tv wall mounts are VESA compliant. This means they will fit the vast majority of Flat Screen TVs out there! However, to be certain of compatibility, please consult the “Compatibility Checklist” portion of each product page on our website, or your TV product manual to ensure VESA compliance.
Myth: Sitting too close to the TV is bad for the eyes. The American Academy of Ophthalmology (AAO) says that kids can actually focus up close without eyestrain better than adults, so they often develop the habit of sitting right in front of the television or holding reading material close to their eyes.
- Screen Time Hurts More Than Kids' Eyes. Too much screen time can result in digital eyestrain, which can include burning, itchy, or tired eyes. Headaches, fatigue, blurred or double vision, loss of focus, and head and neck pain are other threats for children using screens too often and too long.
- Myth: Starring at the computer all day will ruin your eyes. Myth: Crossing your eyes will make them stay like that. Fact: When you cross your eyes for humor or amusement it may cause a few laughs but it will not cause permanent damage to your eyes and once you are done your eyes will return to normal placement.
- Staring at a computer screen can certainly cause eyestrain and fatigue, but you won't go blind. Instead, your eyes may feel tired or you may get eye pain or headaches. And of course, squinting may lead to wrinkles. Look away from your computer screen every 20 minutes or so to give your eyes a break.
