Television sizes are traditionally measured diagonally to provide a more accurate representation of the screen’s overall dimensions. This measurement method originated in the 1950s when TVs were first produced in a rectangular shape rather than the round or oval screens that were popular in the early 20th century. Since then, diagonal measurement has become the standard for TVs, as well as for computer monitors and other display screens.
Benefits of diagonal measurement
There are several reasons why diagonal measurement is more useful than other methods when it comes to TVs. One of the main benefits is that it provides a more accurate representation of the screen’s size. For example, a TV that is 32 inches wide and 24 inches tall would have a diagonal measurement of approximately 36 inches, which would be its size if measured from corner to corner. It is a more accurate representation of the TV’s size than simply measuring the width or height, as it considers that the TV is not a perfect square or rectangle.
Another reason why diagonal measurement is used for TVs is that it allows for more consistent comparisons between different models. When TVs are measured using different methods, it cannot be easy to compare their sizes accurately.
For example, a TV 32 inches wide and 24 inches tall might be considered “larger” than a TV 28 inches wide and 22 inches tall, even though they have the same diagonal measurement of approximately 36 inches. Diagonal measurement makes it easier to compare the sizes of different TVs and determine which one is the right fit for your needs.
Other factors to consider when choosing a TV size
While diagonal measurement is a useful tool for comparing the sizes of different TVs, it’s important to consider other factors when selecting a TV for your home. One important factor to consider is the resolution of the TV, which refers to the number of pixels on the screen. The higher the resolution, the clearer and more detailed the picture.
When selecting a size, you should also consider the distance you will be sitting from the TV. Generally, it’s recommended to choose a TV with a diagonal measurement appropriate for the distance you will be sitting. For example, if you sit relatively close to the TV (say, within 8 feet), you might want to choose a TV with a smaller diagonal measurement to avoid straining your eyes. A larger TV with a higher resolution might be a better choice if you are sitting farther away.
FAQs
Can I use diagonal measurement to compare the sizes of TVs with different aspect ratios?
Yes, diagonal measurement is still a useful tool for comparing the sizes of TVs with different aspect ratios, as it provides a consistent way to measure the overall dimensions of the screen. However, it’s important to consider the aspect ratio of the TV as well, as this can affect the picture’s appearance on the screen.
For example, a TV with a wide aspect ratio (such as 16:9) might have a larger screen area than a TV with a narrow aspect ratio (such as 4:3), even if they have the same diagonal measurement.
Are there any other common methods of measuring TV sizes?
Besides diagonal measurement, TVs are sometimes measured using their width or height. However, these measurement methods are not as accurate as diagonal measurement, as they do not consider that TVs are not perfect squares or rectangles.
They can also be confusing, as different TV manufacturers may use different measurement methods. Using diagonal measurement is the most consistent and accurate way to compare the sizes of different TVs
Is it better to get a larger or smaller TV?
This ultimately depends on your personal preferences and the size of your viewing space. If you have a small room or will be sitting close to the TV, a smaller TV with a higher resolution may be a better choice. A larger TV with a lower resolution may be sufficient if you have a large viewing space or will be sitting farther away from the TV. It’s important to consider both the TV’s size and resolution when making your decision.
Can I use diagonal measurement to compare the sizes of TVs with different resolutions?
Diagonal measurement can be used to compare the overall dimensions of TVs with different resolutions, but it’s important to consider the resolution. A TV with a lower resolution may have a larger screen area than a higher resolution, even if they have the same diagonal measurement. In general, choosing a TV with a higher resolution is a good idea for a better viewing experience, especially if you will be sitting close to the TV.

Can I use diagonal measurement to compare the sizes of TVs with different display technologies?
Diagonal measurement can be used to compare the overall dimensions of TVs with different display technologies, but it’s important to consider the technology. Different display technologies, such as OLED, LED, and LCD, can affect the picture quality and overall viewing experience differently. In general, it’s a good idea to research the different display technologies available and choose one that meets your needs and preferences.
