What is Space and Distance Calculation for TV?

The method of finding the best viewing distance from the television to the viewer is the space and distance calculation. It is the key factor in getting a great viewing experience. The sitting distance depends on the TV size and screen type. For a traditional 1080-pixel HDTV, the TV size and distance ratio is about 1.5 to 2.5 times the screen's diagonal length.

So, the following is the space and distance calculation for different TV sizes: 

-For a 40’’ TV the sitting distance is between 5 to  8.5 ft away from the TV screen.

-For a 43’’ TV– The sitting distance is between 5.5 to 9 ft away from the TV screen.

-For a 50’’ TV– The sitting distance is between 6.5 and 10.5 ft from the TV screen.

-For a 55’’ TV– The sitting distance is between 7 and 11.5 ft from the screen.

-For a 60’’ TV– The sitting distance is between 7.5 and 12.5 ft from the screen.

-For a 65’’ TV– The sitting distance is between 8 and 13.5 feet from the screen.

-For a 70’’ TV– The sitting distance is between 9 and 14.5  ft from the TV screen.

-For a 75’’ TV– The sitting distance is between 9.5  and 15.5  ft from the TV screen.

-For an 80’’ TV–The sitting distance is between 10 and 16.5  ft from the TV screen.

-For an 85’’ TV–The sitting distance is between 10.5 and 17.5 ft from the TV screen.


On the other hand, The standard TV watching distance for a 4K Ultra HD TV is between 1 to  1.5 times the screen's diagonal length. For example 

-For a 40’’ Television– Your sitting distance is between 3.5 to 5 ft from the TV screen.


1. Why it's important to pick the right size television?

Right-sized TV selection is more important than a bigger screen. Because if the screen is excessively large and you sit close to it, you might suffer from eye problems like eye strain and pain. 

Even if the size is bigger, you may only watch a part of the picture on your TV. So, only the right-size TV can provide the best TV-watching experience. Picking the right screen size for your TV is more important than being bigger.

2. Is a television an appliance?

TV is a class two appliance that has a plastic cover. Class two appliances are those that have two-layer insulations. The plastic connectors provide the basic insulation, and the plastic casing adds an extra layer.

Advertisements or ads are louder than TV shows due to the audience's attention.  The multiband compression technique is used to make the advertisement louder. It splits audio sounds in different tones at a digitally allowed maximum limit. So the ad is always louder than the tv shows.

4. What is the average lifespan of a new TV?

The lifespan of a TV is between 4 to 10 years; in terms of hours, it is 40,000 to 1,00000 hours. It varies on the manufacturing, use, and maintenance of the television. You can increase the lifespan of your tv set by taking care properly.

5. Which is the best TV for gaming and sports?

You must purchase a TV with specific features, such as a high refresh rate, high color resolution, black-level specifications, etc., to play sports and video games. High resolution reduces the motion blur, and a big screen makes the game more enjoyable.

6. Is it worth investing in curved and OLED Television?

The OLED and curved TVs offer great contrast quality, better pictures, less energy consumption, and an immersive viewing taste. The downsides of the curved tv are the high price and specific viewing angle.

But the worth of your investment depends on the usage of your TV set. A bigger screened 4K TV is good enough to watch movies and TV shows.
