Process of Measuring For Installing A TV:

1. Diagonal Measurement Of TV:

The step from where you can start the process of measurement of your TV is the diagonal measurement. The diagonal measurement is necessary to be done just because most of the TV size measurements are done this way. The majority of TV companies use this type of measurement for their products.

As far as kind of measurement is concerned, you can perform it by measuring from one side of your TV screen to the other one. However, the most common and practical way of calculating this measurement is to start from the top left corner and end at the bottom right corner.

By calculating the TV screen as per the above-mentioned methods, you will get the diagonal measurement of your TV screen. As we know that TV products range from small size to medium as well as large sizes. So the diagonal measurements of your TV screen may also range from 24 in (61cm) to 72 in (180cm) or even larger than this size.

2. Calculate The Width Of Your TV Screen:


After the successful calculation of the diagonal measurements of your TV screen, the next step is the simple calculation of the width of your TV screen.  The calculation for width means to calculate it from one end to the other in a linear manner.

It is up to you whether you start from the left and end at the right or vice versa. However, most professionals and experts prefer measuring from the left toward the right. So, it would be better for you to follow the same.

For example, the thickness or depth of modern TVs is reducing day by day. Some of the TVs nowadays have a depth as low as 10 inches along with the stand. If we remove the depth of the stand, then their thickness comes out to be just three inches or even less.
