Are TVs Measured Corner To Corner?

To have a flawless view of the television that is large enough to give viewers a fascinating but not overly broad experience, it is crucial to watch from a reasonable distance to avoid obstructing both the view and the overall vision of the scenes shown on screen. The appropriate TV screen size must also be considered when selecting the ideal TV for a space.

To accurately measure a TV screen’s size, the screen must be measured from corner to corner. This measurement is known as the diagonal screen and represents the distance between the opposite corners of the screen. Manufacturers and dealers alike frequently use it to describe a TV’s size. 

The relationship between a TV’s size and the area it takes up may now be better-managed thanks to advancements in technology over time. This article will explore TV measurements and other related factors involved in detail.

Availability Of TVs In Homes

Because of the widespread use of television, this technology is now a part of everyday life for most people. The early televisions were very different from the televisions of today. 

They had black and white screens, blurrier images, and much larger proportions. It is so that the cathode ray tube could operate, which required a specific gap between the rear and front screens. 

TV Size: From Diameter To Diagonal

The cathode ray tube was initially round. So, the size of a television was determined by its diameter. The diagonal became the most significant dimension to be measured when rectangular tubes were invented. It has been used for many types of screens ever since. 

This measurement option could be troublesome because it makes it impossible to quickly and precisely determine the size of a screen. However, the benefits of this measurement approach have always outweighed the drawbacks. 

It has clear benefits for marketing since it is feasible to “speak the same language” and for production because it eliminates the need to make devices in different sizes for various markets. Additionally, it enables customers to shrink a size by a set number of inches consistently.

Size Of TV Measurement

Are you trying to determine the maximum screen size possible? Choosing the right TV size for your area can be challenging when purchasing a new television. In general, more significance is preferable.

Spending more on a big screen is typically the best use of your money because there aren’t many sophisticated TV features that tend to surpass a bigger screen in terms of overall enjoyment. 

People who didn’t go big enough are one of the post-TV purchase complaints television sellers hear most frequently.

It is advisable to get 65 inches for the ideal TV size, with at least 43 inches for a TV in the bedroom and 55 inches for a TV in the living room or other primary area. But how can you tell if you have enough space to expand as much as you want? We have simplified it into a straightforward procedure of steps: 

Step 1: Measure Your Available Space

The dimensions of your room are height, length, and width. Will you mount the TV on the wall or use the stands that come with the TV? Leave at least an inch on the sides and top of the TV cavity if you wish to put it into an existing entertainment center so that ventilation is possible.

While everything may seem obvious, TV scaling can be challenging. It is because overall dimensions and screen size are not always correlated. A TV’s screen size is determined by measuring the panel diagonally from one corner to the other. The TV’s bezel and other exterior surfaces are not included in this. 

Many models in the given sizing category, i.e., 55 inches, 65 inches, etc., are not precisely the size indicated on their labels. Sometimes the viewable display size is a bit smaller or even less than an inch in each direction and falls within a round-up range of the correct size. 

For instance, a 50-inch TCL 4-Series TV has a 49.5-inch visible display. Additionally, there are minor variations in the bezel’s top, bottom, and sides and the frame surrounding the screen. It implies that different models and manufacturers will produce various sizes and dimensions of TVs.

Step 2: Determine The Typical Dimensions Of Popular TV Brands And Sizes

Now that you know its dimensions, it is time to determine what size and brand will fit your room. Even the most giant TVs are only about 10 inches wider. It implies that you could buy a screen that is 75 inches long while only requiring about 66 inches of room. 

Research what the popular TV brands are and what sizes they offer before heading to the shop to buy a TV. It will give you a rough estimate of how room space you have and what average or different sizes of screens are available in the market. 

It will make your hassle in TV selection a bit easier on the day you are in the shop to buy the TV, and you have to install the setup at your house.

Step 3: Pick Your TV

Now that you know the screen size you need, it is time to decide what brand and model is best for you. Beyond measure, many other factors exist, like display kind, picture quality, and innovative TV features. 

A few significant considerations have been listed below:

  • LED LCD technology is used in almost every TV, including Samsung’s QLED model. The majority of tablets and monitors employ the same basic technology.
  • Local dimming LED LCD TVs frequently perform better than those without. Quantum dots and mini-LED are other technologies in LCD TVs that help with image quality. \
  • OLED TVs have an entirely different screen lighting system than LED TVs. They still cost a lot of money even if they feature the finest picture quality. 
  • The critical component of a good image is the capacity to create a deep shade of black, which translates into great contrast. For HDR to operate optimally, image brightness and local dimming are crucial. 
  • Although a TV’s built-in intelligent streaming system is crucial, you can always add a streaming device if it doesn’t accomplish everything you want.


Choosing the appropriate TV size is essential for the best watching experience. The screen size can occasionally vary since TVs are measured diagonally from corner to corner. When selecting a TV size, it is important to consider the available space, the measurements of major TV brands, and additional elements like display type, picture quality, and cutting-edge features.
