## Discovering the Perfect TV Screen Size for Your Space: A Detailed Guide

The resolution of a television screen is one of the most important factors that define its quality. Technically, a resolution is defined as the total number of pixels on the screen.

A TV screen is a grid of pixels. If we multiply the number of pixel columns by the number of rows we obtain the total number of pixels on the screen, that is, its resolution.

Resolution is important because it is related to the sharpness of the image. The higher the number of pixels, the higher the resolution and therefore the better the sharpness of the images.

## Most common resolutions

There are different trade names to identify different levels of resolution. These terms have been changing and evolving as technology has improved. Below is a table with the most common terms currently and the corresponding resolution.

The total number of pixels is obtained by multiplying the number of horizontal pixels by the number of vertical pixels. That is to say:

• HD: 1280 x 720 = 921600 pixels ~ 0.9 Megapixels
• Full HD: 1920 x 1080 = 2073600 pixels ~ 2.1 Megapixels
• Ultra HD: 3840 x 2160 = 8294400 pixels ~ 8.3 Megapixels

It is very common to express the resolution only by the number of vertical pixels, that is, 720, 1080 or 2160. The total resolution can then be calculated assuming that the aspect ratio of the television is 16: 9. The letter 'p' written after the resolution number means 'progressive' and refers to the electronic method by which the image is generated on the screen. An alternative method is known as interlaced and is represented by an 'i' (interlaced).

The number of columns of pixels in an Ultra HD television is double that of a Full HD television, it goes from having 1920 columns of pixels to having 3840. Similarly, it goes from having 1080 rows of pixels to having 2160, also double. The result is that the total resolution is multiplied by four. While a full HD TV has 2073600 pixels, an Ultra HD TV has 8294400 pixels.

## Aspect ratio

The aspect ratio of a television is the ratio of its width to its height. Currently, the most common aspect ratio on televisions is 16: 9. This means that for every 9 units of height we have 16 units of width. Alternatively, it can be said that the width is 1.78 times the height.

A few years ago the standard aspect ratio of the vast majority of televisions was 4: 3. That is, the width was 1.33 times the height. This format has been outdated today since most programs are broadcast with high definition and 16: 9 aspect ratio.

It is also important to note that the format commonly used in cinema has an aspect ratio of 21: 9, resulting in an image even more panoramic than 16: 9. This causes two horizontal black bars to appear when a cinema movie is played on a high definition television.

## TV size

The size of a television screen is usually defined by the length of its diagonal. Instead of indicating its height and width, only the value of its diagonal is indicated in inches. This can be transformed to centimetres since one inch equals 2.54 cm.

If we know the diagonal length of a screen and its aspect ratio (which can usually be assumed equal to 16: 9), it is possible to calculate its width and height.

The inches of television and its resolution are not necessarily related. More inches only mean that the TV is bigger, but not that it has more resolution. For example, a 40-inch Full HD TV and a 50-inch TV have the same number of pixels, and therefore the same resolution. The only difference between these two TVs is the pixel size.

## What is the difference between 4K and UHD?

There is some confusion surrounding the terms 4K and UHD (Ultra-High-Definition). This is because there is a 4K format for televisions and a 4K format for cinema.

The 4K format in the world of cinema is equivalent to a horizontal resolution of 4096 pixels. In televisions, the designation 4K is used as a synonym for UHD, which indicates a horizontal resolution of 3840 pixels.

This difference can lead to confusion in certain contexts. In general, UHD televisions are advertised as 4K although in reality their horizontal resolution does not reach 4K and is lower than that achieved in the cinema. However, the name 4K is more commercially attractive and has become synonymous with UHD.

## New resolutions

The resolution that will surely become common soon is 8K resolution. This resolution is equal to a number of pixels of 7680 x 4320, that is, a total of 33177600 pixels or 33.2 megapixels. This resolution is four times the current resolution of 4K TVs and will likely be the new standard in a few years.

## TV dimensions length and width

Many people are interested in what screen size the TV or monitor will have depending on the diagonal, since the diagonal does not give much information, also, we used to use the old TV standards, with the size of the TV with an aspect ratio of 3 × 4. But now this standard is a thing of the past, and all new TVs are available in the standard with an aspect ratio of 16 × 9, monitors also have other aspect ratios, the most common monitor size is 21: 9.

So, the 21: 9 standard is quite popular, 21: 9 resolution monitors are shorter in height but wider, for example a 26 inch monitor will be 2.5 inches in size. (6.4 cm) smaller than 16: 9 monitors; they are more suitable for tables like the exel. When selecting a TV or monitor, keep in mind that the actual size of the TV will be 0.5-1.5 inches. (1-4 cm) larger due to the frame that supports the screen.

In the table below, you can see the size of your TV and monitor, between 19 and 105 inches in length and width. The table can also be used when selecting an advertising screen.

## TV size, aspect ratio 16: 9 and 21: 9 depending on the diagonal

In this table you can find out which size of the TV corresponds to a certain size of the screen diagonal. The table shows the most common diagonal sizes. See the translation of the most popular sizes are 32 inches, 40 inches, 50 inches, 55 inches, 60 inches in length and width of the TV.

## How do inches translate into inches

1 inch equals 2.54 cm. For example, a 7 inch TV 7 × 2.54 = 17.78cm. But for simplicity, here is a table that translates inches into centimeters. Information in table form is more noticeable.

The table shows all sizes in inches from 19 inches to 120 inches, using the table you can easily translate the diagonal screen size from inches to centimeters

## The most common sizes of televisions

For example, you want to buy a 55- or 65-inch TV, but you're not sure if the size will fit you. The question is how wide is the 55-inch TV and how wide is the 65-inch. The table below shows the most common TV sizes, diagonal. Please check your TV screen size before purchasing.
