When it comes to TV size it’s important to consider the room size that the TV will be installed in and the average distance of the viewer from the seated position to the screen. Even though we would all like a huge 85″ TV or even larger it’s not always practical. Bigger is not always better.
Screen size and resolution
First, remember, TVs are measured diagonally. So a 42-inch screen measures 42 inches from one corner to the opposite corner.
Next, you have to consider the resolution of the TV. That’s because the higher the resolution, the closer you can sit before you’ll notice pixelation in an image. That means you can sit closer to a 4K TV (3840 x 2160) than you could a 1080p TV. This is an important factor to consider when thinking about screen size; because you can sit closer to a 4K set, you don’t need to get as large a TV to fill your field of view as you would with a 1080p TV.
Consider the room in which the TV will sit. As long as the furniture in that room is not permanently attached to the floor — and you’re willing to move it — then you have some flexibility in the size of the TV you can get.
Take for instance the picture on this post a 85″ TV in a room that measures about 15 feet in width and 22 foot in length with a viewing distance of of about 9 feet because it’s a 4K TV if this were a 1080P we would recommend the viewer to sit 12-13 feet away.
Hanging the TV on the wall, on the other hand, can add a foot or more to the viewable distance, which can be the difference between a 60-inch TV and a 72-inch model. Depending on what sort of mount you use and the thickness of the TV, your screen will still sit a few inches from the wall, but the specifics will vary from one model to the next.
What’s comfortable for you?
The typical TV-watcher sits 9 feet from the tube, which brings us to the comfort factor: Most people like to sit far enough away from a TV that the pixels almost don’t factor into the equation. So, feel free to experiment with the placement of your new TV, and it never hurts to go a little bigger than what you think you’ll need.
Viewing angle (TV Height)
This is another thing you have to consider and we will discuss this in another post.
