When selecting a television for you home, you must consider your seating distance from the televisions, the resolution of the televisions, and the size of the televisions. You must match the size of the television to your seating distance and the dimension of the room in which you will be watching televisions. A television that is too small will not fill your field of vision when you are seated, while a television that is too large may cause discomfort in your viewing location.
The distance between your eyes and the television is the primary factor in determining the size of the television that you should purchase, while the resolution of the televisions is the secondary factor in making that determination. The distance at which you sit relative to the television can impact the viewing experience and the resolution of the television that you are using. If the resolution of the televisions is low (such as a 1080p television) and you sit too close to the television, you will begin to observe individual pixel on the screen.
How to Choose the Right TV Size and How Far to Sit
If you sit too far from the television relative to its size, the image on the television will be too small for you to fully view. Televisions with higher resolution (such as 4K televisions) allow for individuals to sit closer to the television because the higher resolution result in more pixels in the screen that allow for more even viewing of every portion of the screen. The viewing distance that you should use for your television can be calculated by the resolution of the televisions and a set multiplier.
For 1080p televisions, the ideal viewing distance is between 1.5 and 2.5 time the diagonal size of the television screen. For 4K televisions, the ideal viewing distance is between 1 and 1.5 times the diagonal size of the television screen. Organizations like THX and the SMPTE established these measurements.
Both organizations recommend specific angle (36 degrees for THX, 30 degrees for the SMPTE) as the ideal viewing angle for televisions to fill the viewer’s vision while providing an enjoyable viewing experience. Finally, the type of room in which you will be placing the television will dictate the size of the television that you should purchase. For instance, if your bedroom is small and your bed is eight feet from the wall, a 40-inch 4K television may be the best resolution for your televisions.
In contrast, a living room that is larger with a sofa that is 12 to 15 feet from the televisions may require televisions with a screen size between 55” and 65” to provide adequate viewing for all of the in
In an open floor plan or in a basement where the seats are further away from the television, you should choose a television that is at least 75 inch in size. You should match the size of the television to the depth of the room in which it is to be displayed, as televisions that are too large for the room will overwhelm the space. The resolution of the television also play a role in the size of the television that is to be purchased.
A 1080p resolution requires more distance between the viewer and the screen to hide the pixels on the screen. A resolution of 4K allows for the viewer to sit closer to the screen due to the reduction of the distance required to hide the pixels. An 8K resolution contains even more detail than 4K televisions, but requires very large televisions and very close viewing distances to allow those pixels to be noticeable to the viewer.
You should also consider the mounting height of the television when purchasing the television. The viewers should mount the center of the screen to the wall to be viewed at eye level when they are seated, typically between 42” and 48” from the floor. In spaces where the television is mounted above a fireplace, for instance, the screen may have to be tilted down 10 to 15 degree from the ceiling.
Failure to tilt the television to account for the viewing height will result in neck strain for the viewers. The lighting in the room also impacts the viewing experience of the television. In homes with windows behind the viewers or the televisions, the screens may reflect the light from the outside world.
In a dark room, an OLED television is beneficial because the screens provide deep blacks in the image. In bright rooms, however, a QLED or Mini-LED television is beneficial because these televisions has high brightness to account for the ambient light in the room. Additionally, bias lighting, or LED strip placed behind the screen, can help to reduce eyestrain and increase the contrast of the screen.
The aspect ratio of the televisions should also be considered. Most content streamed from the internet or watched on televisions have a 16:9 aspect ratio; televisions with this aspect ratio will display these video without black bars on the sides of the screen. Some film, however, use a 21:9 aspect ratio to provide additional screen real estate to view content like movies without black bars on the sides of the screen.
Finally, to order a television for your space, measure the distance that the viewers will be from the screen, select the resolution of the screen, and finally select the size of the screen.
