Hdtv which size

Since ratio is the width will be 21 inches. So the diagonal size is For a 40 inch widescreen HDTV, the natural picture without zooming will be the equivalent of watching it on a 33 inch TV.

Then use the TV size to minimum watching distance chart given below to get an idea of the best size TV to buy. The table chart below compares TV size to the minimum sitting distance required to watch TV. The TV viewing distance is the distance from the TV screen to the approximate position of your eyes when viewing TV regularly.

TV size and viewing distance are important factors to decide on the size of TV to buy. Thus the best distance to sit from a 60 inch HDTV will be 90 inches or 7. There are no official bodies, as yet, to recommend viewing distance for TV size.

One of the leading Companies in the world of surround sound, THX, recommends viewing distance as follows. To quote from the THX website:. How do you calculate the best seat-to-screen distance for a TV or projection screen?

Divide the size of your screen by. For example, a inch TV divided by. Sitting closer to HDTV than this 1. If you are sitting straight in front, you are sitting at Zero degrees, as you go right or left to the side of the TV, the angle increases to 90 degrees when you reach a point parallel to the TV. Most TV manufacturers specify the total viewing angle, which is the angle from the farthest left to the furthest right the TV can be viewed, as is shown in the figure here. The best position to watch TV will be straight in front of the TV which will be zero degrees.

You can sit farther away, but may lose the ability to distinguish some of the finer details offered by 4K. And as larger screen sizes become more affordable, you'll want to take these guidelines to heart. Whether you're trying to fit a inch or inch TV into your home, remember that the goal is to see the picture, not the pixels.

Thanks to the higher pixel density of 8K TVs, you can get closer to an 8K set without seeing the individual pixels, but the larger screen sizes of most 8K models don't lend themselves to closer seating arrangements. The typical TV-watcher sits 9 feet from the screen, which brings us to the comfort factor: Most people like to sit far enough away from a TV that the pixels on the screen can't be distinguished.

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.

Whether you're shopping for a TV for your home or a home for your TV, you can now figure out the perfect viewing distance with just a couple of quick calculations.

In this article the distance calculation that is made is for distortion on the pixel lines. That is the only consideration that the article is making.

The other consideration should be the peripheral vision. If you are placed so close to the TV yours eyes will be shifting constantly to view the area of view which will make it difficult and unpleasant to your vision. This should be your first consideration. After considering that one can make the other considerations to make your viewing a pleasurable and complete experience.

Okay, this entire guide is silly, and I have no idea where you got your numbers from. How far away people like to sit away from the TV is entirely subjective. We purchase our own TVs and put them under the same test bench, so that you can compare the results easily. No cherry-picked units sent by brands. Bigger and closer is usually better when it comes to choosing the perfect television for your room. Size not only affects the price of a television, but it also has a huge impact on the perceived picture quality.

Use our size to distance calculator to see which size TV you should get based on how far away you'll be sitting from the screen. A lot goes into determining the best viewing distance, and there are several different criteria you can use. Aside from size, things like resolution and even how strong your eyesight is can affect how you see the screen.

Because everyone's eyesight is different, this is less an exact science and more of a general guide based on scientific principles of vision and resolution. Since resolutions found today are almost exclusively 4k Ultra HD , it takes a very big TV watched from very close to see imperfections related to the resolution. Because of this, you can sit closer to your TV than you would with lower resolutions and have a more immersive experience.

Think of it like a movie theater: the more a TV fills your view, the more immersive it will feel. That doesn't mean you should be sitting a foot away from your TV. Having the largest screen possible isn't always ideal.

The human visual system has a total horizontal field of view of about degrees, although a portion of that is peripheral vision. While it makes some sense to get as large a TV as you can for movies, not all content is made to fill the entire field of view. This becomes very apparent if you try to watch sports from up close while fixating on a single part of the screen, which quickly starts to feel nauseating.

This is generally good guidance, but people who use their TVs mostly for watching movies might benefit from sitting a bit closer to get a more theater-like experience.

It's also worth noting that this angle assumes a single person is viewing the TV head-on at eye level. Not all living room setups meet these conditions exactly, so it's best to use this as a guideline only. Learn more about viewing angles. Angular resolution is the point at which the eye can 'resolve' or distinguish individual details in an image. Our ability to resolve details is determined not only by visual acuity but also by distance.

At a certain distance, depending on your eyesight, your eyes won't be able to distinguish every detail. So, if you sit too far, your eyes won't be able to resolve the image, but if you sit too close, that image will appear pixelated. For lower resolutions, you have to sit a bit further than preferable to not notice the pixels, while 4k resolutions and higher give you more freedom.

For instance, sitting close to a p TV can look almost like watching through a screen door because you can see the individual pixels, even if it's playing a high-quality p HD movie. Increasing your distance to the TV also increases the density of details, producing a better image. Since 4k TVs have such a large density of pixels, it's much more difficult for this issue to arise.

You need to be quite close to a fairly large TV for the pixels to be noticeably distracting. With 8k TVs, that density increases further, making it even harder to notice flaws with the resolution unless you're sitting extremely close. However, this also decreases the point at which the perceived difference in picture quality becomes noticeable. Because the pixels are more densely packed with an 8k resolution, you need to sit closer to actually resolve those details.

For that reason—content aside—8k only really makes sense if you want a really big screen and plan on sitting close to it. Learn more about the difference between 4k and 8k.

All that said, everyone's eyesight is a little different, and most TVs now are at least capable of 4k, so visual acuity isn't really the best way to find the right distance. It should instead be used to figure out the closest you can sit to a TV without hitting its resolution limitation.

This chart shows the point at which an upgrade in resolution becomes worth it depending on size and distance to the TV. Each line represents the optimal viewing distance for each resolution, but any TV that falls within the range of that color will be suitable to notice a difference in picture quality.
