How big is a 42-inch TV

TV Sizes and Viewing Distance

A 42-INCH TV measures roughly 52 cm in height and 93 cm in width.
The center of the TV screen should be at or slightly below eye level when placing or mounting the device.
The majority of experts advise placing the TV’s center about one meter from the ground.
A TV placed too near to your couch may temporarily strain or tire your eyes.
One common recommendation for Full HD TV owners is to use 4.2 cm of viewing distance for every inch of diagonal screen size.
You can use 2.1 cm of viewing distance for every inch of diagonal screen size on 4K and Ultra HD TVs.

Which TV size is best to purchase? The answer to this straightforward question is also straightforward: Get the largest, greatest one you can afford.

A TV intended for the living room will not resemble a TV that is occasionally used in the kitchen, garage, or bedroom. Finding a TV that fits the dimensions of the space is a smart method to reduce your selections.
The majority of living rooms and dens will look great with mid-size TVs (42 to 55 inches). Mid-size TVs are ideal for larger shared rooms because they are large enough for everyone to watch, but not so large that you can’t turn them off if you want some quiet time.
Choose the largest models (55 to 80 inches) if you’re fortunate enough to have a specially built, dedicated home theater with remote lighting and external audio. Go big if your room was intended for TV viewing, as large TVs grab everyone’s attention.
Knowing where your new TV will end up in the room can help you choose a size, whether you’re mounting it on the wall or fitting it into an entertainment center. It’s not necessary to pull out your blueprints. Just be mindful of the space you have available.
To make a comfortable viewing area, you can usually move furniture around if you purchase a TV that is slightly too large for the available space. On the other hand, you cannot simply stretch it out later if you purchase one that is too small.
Here’s a sensible generalization: A TV appears much larger when it is 10 inches or more larger.

The next subject is the size of a 42-inch LED TV.
A 42-INCH TV measures roughly 52 cm in height and 93 cm in width.
The center of the TV screen should be at eye level or just slightly below.
The majority of experts advise placing the TV’s center approximately one meter from the floor.
One common recommendation for Full HD TV owners is to use 4.2 cm of viewing distance for every inch of the diagonal screen size.
With regard to 4K and Ultra HD TVs, this can be marginally changed. For each inch of the diagonal screen size in this instance, you can use 2.1 cm of viewing distance.

For optimal viewing, the Society of Motion Picture and Television Engineers advises positioning yourself so that the screen occupies at least 30° of your field of vision.
According to the chart, upgrading to 4k UHD may not be worthwhile after a certain point—for example, if you have a 55" TV and are seated more than 7 feet away.
You can arrange your living room so that the resolution of your TV is fully utilized by knowing the ideal viewing distance for the resolution.
Your perceived pixel density will decrease with distance.
Lower resolutions require you to sit farther away than ideal in order to avoid seeing the pixels; 4k resolutions and higher give you more room to maneuver.
A TV’s cost is typically exponential in relation to its size.
For mixed usage, we suggest a field of vision of roughly thirty degrees.
