How to Measure Your TV Screen: A Complete Guide

Understanding TV Screen Size and Aspect Ratio

When it comes to measuring a TV screen, understanding the screen size and aspect ratio is important. Screen size refers to the diagonal measurement of the screen, typically in inches. The aspect ratio, on the other hand, is the proportion of the width to the height of the screen.

Most modern TVs have a 16:9 aspect ratio, which means that the screen is 16 units wide for every 9 units in height. This is the same aspect ratio as most widescreen movies and TV shows, and it has become the standard for modern TVs.

However, some older TVs may have a 4:3 aspect ratio, which means the screen is almost square. This was the standard for TVs for many years, but it has become less common as widescreen content has become more popular.

Understanding the aspect ratio of your TV is important because it can affect how content is displayed on the screen. If you are watching a widescreen movie on a TV with a 4:3 aspect ratio, for example, the movie may appear with black bars at the top and bottom of the screen. Similarly, if you are watching an older TV show on a modern widescreen TV, the show may appear stretched or distorted.

Measuring TV Screen Diagonally: Step-by-Step Guide

Measuring your TV screen diagonally is the most common way to determine the screen size. To measure your TV screen diagonally, follow these steps:

  1. Place your tape measure or ruler at one corner of the screen. Make sure the tape measure or ruler is touching the screen.

  2. Extend the tape measure or ruler across the screen to the opposite corner. Make sure the tape measure or ruler is still touching the screen.

  3. Read the measurement on the tape measure or ruler. This measurement is the diagonal length of your TV screen.

If your TV screen is curved, you can still use this method to measure the diagonal length. Just make sure to follow the curve of the screen with your tape measure or ruler.

It’s important to note that the screen size is usually measured in inches. So, if you get a measurement of 55 inches, for example, that means your TV screen is 55 inches diagonally.

Measuring TV Screen Width and Height: Alternative Methods

While measuring the diagonal length of the TV screen is the most common method for determining screen size, there are alternative methods for measuring the width and height of the screen.

One method is to measure the width and height of the screen directly. To do this, place your tape measure or ruler at the top left corner of the screen and measure across to the top right corner for the width, and from the top left corner to the bottom left corner for the height.

Another method is to look up the specifications of your TV model online or in the TV manual. The specifications should include the screen size as well as the width and height of the screen.

It’s important to note that measuring the width and height of the screen may not be as accurate as measuring the diagonal length. Additionally, measuring the width and height can be more difficult if the TV has a curved screen or if the screen is inset into the TV bezel.

How to Measure Screen Size for Wall Mounting

Measuring your TV screen size is especially important if you plan to mount your TV on the wall. When selecting a wall mount, you will need to ensure that it is compatible with your TV’s screen size and weight.

To measure the screen size for wall mounting, you can use the same diagonal measurement method described earlier. However, it’s important to also consider the VESA (Video Electronics Standards Association) pattern of your TV.

The VESA pattern refers to the distance between the mounting holes on the back of the TV. This distance will determine the type of wall mount that is compatible with your TV. You can typically find the VESA pattern listed in your TV’s manual or on the manufacturer’s website.

When selecting a wall mount, make sure that it is rated to support your TV’s weight and screen size, as well as the VESA pattern. It’s also important to ensure that the wall you plan to mount the TV on can support the weight of the TV and the wall mount.

Common TV Screen Measuring Mistakes to Avoid

While measuring your TV screen may seem straightforward, there are some common mistakes to avoid to ensure that you get an accurate measurement.

One common mistake is measuring the TV screen from the outer edges of the bezel, rather than from the edge of the screen itself. This can result in an inaccurate measurement and may affect the fit of a wall mount or other accessories.

Another mistake is measuring the TV screen at an angle rather than straight on. This can also result in an inaccurate measurement, particularly if the screen is curved.

Finally, it’s important to make sure that the tape measure or ruler is touching the screen or following the curve of the screen if it’s curved. Any gaps between the tape measure or ruler and the screen can also result in an inaccurate measurement.

By avoiding these common mistakes and following the recommended measuring methods, you can ensure that you get an accurate measurement of your TV screen size.
