# Unlocking Screen Measurements: A Hidden Secret.

TV Measurement

Have you ever wonder why is TV's measure in diagonally?

Television screens are measured diagonally for a few key reasons:

1. Historical Convention: The practice of measuring television screens diagonally dates back to the early days of television technology. Cathode ray tube (CRT) televisions, which were among the first commercially successful TVs, had curved screens. Measuring the diagonal provided a consistent and standardized way to describe the size of these curved screens. This convention has continued even as newer flat-screen technologies have replaced CRTs.

2. Accounting for Screen Size Variations: Television screens are not always a perfect square or rectangle. They can come in different aspect ratios, such as 4:3 or 16:9, making it challenging to describe their size accurately with just width or height measurements. Measuring the diagonal allows consumers to easily compare the overall screen size regardless of the screen's aspect ratio. This helps consumers understand how much screen real estate they are getting for their money.

3. Design Considerations: The diagonal measurement provides a straightforward way to communicate the size of a TV, which is important for marketing and consumer understanding. It allows manufacturers and retailers to label and advertise TV sizes consistently and intuitively, making it easier for consumers to choose a TV that fits their space and preferences.

4. Consistency Across Technologies: The diagonal measurement provides a common language for describing screen sizes across various types of televisions, from traditional CRT TVs to modern flat-screen technologies like LCDs, LEDs, OLEDs, and more.

In summary, the diagonal measurement is a convention that simplifies the description and comparison of TV screen sizes, accounting for screen size variations and making it easier for consumers to understand and choose the right TV for their needs.

Why some of the TV's have the same Diagonally measurement but different in the size ?

The diagonal measurement of a TV is generally standardized to be its inches. However, there can be slight variations in the actual width and height dimensions of a TV, even if the diagonal size remains the same. These variations can occur for several reasons:

1. Bezel Size: The bezel, the frame around the screen, can vary in width between different TV models and manufacturers. Some TVs may have thicker or thinner bezels, which can affect the overall dimensions. In some cases, a TV's advertised screen size might exclude the bezel, while others may include it.

2. Aspect Ratio: The aspect ratio of a TV can affect the width and height of the screen. A 49-inch TV with a 16:9 aspect ratio will have different dimensions than a TV with a 4:3 aspect ratio.

3. Display Technology: Different display technologies, such as LCD, LED, OLED, and QLED, can result in variations in the thickness and design of the screen itself. These variations can affect the overall dimensions of the TV.

4. Manufacturing Differences: Manufacturing tolerances and methods can also lead to slight variations in the actual dimensions of TVs. Quality control and the precision of the manufacturing process can impact the exact measurements of the TV.

It's essential to check the specific product specifications provided by the manufacturer to get precise dimensions for a particular TV model. These specifications will include the exact width, height, and depth of the TV, which can be more informative than just the diagonal screen size when you need to determine if a TV will fit in your desired space.
