TV Purchase Guide – TV Size


TV Purchase Guide – TV Size

One of the most parameters that we should decide before purchasing a television, is defining what size is more suitable for our place. Although part of this decision depends on our preference, but other part is related to some standards which is recommended to take into account when purchasing a TV.

The technology is developing very fast as well as the televisions. That is, these days people can buy televisions with bigger and higher screen quality with less money. Their technologies have been also changed that we will explain different TV technologies from LCD TVs to LED TVs in our next articles.

But in this article our focus is on choosing the best television size which suits us better.

Many people just buy the television without checking if the TV is suitable for the desired place or not. They just think they can place the new TV to their previous TV spot without considering their technology differences, their screen size and also their tendency to watch in a big screen. Therefore, it is important to identify the appropriate TV size in the beginning.

The rule is the same and as we may use the televisions in various places, such as in living rooms, bedrooms, kitchen and many more places. Therefore, we can use this method to know which size is the best to that desired space as follows:

  • Television Resolution and Television Size
  • Designated Space and Television Placement
  • Defining The most Suitable Television Size for Your Desired Space

Television Resolution and Television Size

First we should know what does Resolution means. When you are talking about display resolution, you define the number of each pixels to each dimension. Therefore higher resolution means more pixels. To clarify, if you have a television with higher resolution, you sit closer to the TV without noticing the pixels. For example, if you have 8K Television, you can sit closer to it in comparison to a 4K television, therefore you are not required to buy a big display to fulfill the need of watching in a vast field of view.

Apart from this, many of us may make a mistake defining television size and dimensions to screen size.

  • Television size and dimensions: Actual TV size meaning its width and its length. For example the dimension of a 55-inches TV can be approximately 49 inches length and 29 inches width.
  • Screen size: Measuring the distance between top left of the TV to the bottom right of it or measuring the distance between top right of the TV to the bottom left of it (Corner to Corner)

Designated Space and Television Placement

There are some factors which can affect your choice about the size of the TV you want to buy. For example, if the setting of the room in which you will place your TV can be changed. It means, if can you change the decoration or change the position of the furnitures. Because in this case you can have more flexibility to choose the size of your TV. Imagine a situation that the room is too small or the furnitures are attached to the ground, then you only had one choice of calculating and defining the distance and buy only that specific TV size.

Not only this, but also the setting that you want to install the TV will also affect your decision. For example, if you want to install the TV with the included stands on a TV table, then it would be closer to the viewers. Therefore a smaller television should buy in comparison to a situation that you want to mount a TV on a Wall. Because when you mount a TV on a wall will add more than one foot distance to the viewers, that this amount of extra distance can change your decision to buy a 72-inches TV instead of 60-inches TV.

Defining The most Suitable Television Size for Your Desired Space

As it was mentioned in previous section, one of the key factors in defining the size of TV is its resolution and then its distance to the viewer.

Therefore, we will take the following steps:

  1. First base on our situation meaning our room size and the placed furnitures, we have to measure the distance between the desired TV position and the place that viewers will sit.
  2. After measuring the distance, then we have to calculate the TV size based on the resolutions. For 1080 TV resolution there is a specific formula which is slightly different from 4K TV resolution.

After doing the two above steps, now we should refer to one of the most trusted sources which is Amazon. It is recommended for 1080 televisions a distance of 1.5 to 2.5 times screen size. For example if the TV resolution is 1080 with 40-inches screen, the distance should be between 60 to 100 inches equal to 5 to 8.3 feet.

However, it is not the only formula and there are many other recommendations by experts that we also can let you know about them in our future articles.

For example based on Crutchfield, for 4K Ultra HD TVs it is recommended a distance closer than 1 to 1.5 times of the screen size. For example, if you want to buy a 55-inches TV, you should sit in a distance between 4.6 to 6.9 feet to the TV.

For your comfort you can use the following tables based on the above formula to define the TV size:
