If you have to buy a new TV or a new monitor for your PC, decide the greatness we can not only think about aesthetics, but also a how far or close the screen can be respect the position in which we are seated.
Most home theater enthusiasts naturally apply the "bigger is always better" philosophy, which is often true, but not always.
Sometimes a larger screen doesn't necessarily improve the picture, and spending more on a 4K resolution TV might be pointless depending on the size of the room and the distance you plan to sit from the screen.
In short, if you sit down too close to a large TV with a lower resolution, you risk seeing the individual pixels of the screen, thus ruining the vision.
Conversely, if you sit further from the screen and you buy a 4K TV that is too small, you won't be able to enjoy the higher resolution and you won't be able to distinguish the extra pixels compared to a cheaper TV.
The key factor in the balance between screen size, resolution and viewing distance is called angular resolution which indicates the ability of the eye to distinguish the small details of an object.
Although the angular resolution varies according to the view of each individual person, in general, after a certain point, everyone loses the ability to distinguish details when they are at a certain distance from the screen and everyone can see individual pixels if they get close. too.
Based on this information, you can use math to find the right distance to stand depending on the size of the screen or, similarly, buy the right size TV based on the expected distance in your living room or bedroom.
From our website Rtings.com there is an interactive graph where you just need to move the sliders of the distance in meters and the screen size in inches to find the right combination.
Another tool to find at what distance to see the screen of a TV or monitor is on the site Staric where you can find the optimal angular resolution.
As can be seen in the tables, however, there is not an optimal fixed distance, but a range that depends on the person's sight.
There is no absolute answer for the perfect TV size, but rather a range in which a certain size and resolution becomes the right one.
To use the graph, you must choose the display distance from the vertical y axis, to be combined with a resolution and a dimension on the x axis.
For example, if you want a 4K UHD TV, if the expected distance between the sofa and the TV cabinet were 3 meters, the optimal size would be 75 inches to be able to see the difference between a 4K and Full HD 1080p.
On the other hand, if you want to position yourself in an optimal way compared to an older TV at 1080p resolution of 40 inches, you would have to stay at a distance of 2 meters in order not to see the individual pixels of the whole.
If you buy a 4-inch 65K TV, you should stay 1,8 meters away from the screen for the best balance while watching a TV with the same size but 1080p resolution should be 3 meters.
The distance calculator and graph are great tools that not only help you find the optimal size for the best viewing experience for TVs and computer monitors, but also help you avoid wasting money when you go to buy a new screen.
Below is the table of optimal distance expressed in meters for a Full HD TV with 1080p resolution
- 19 "screen from 0,7 to 0,9 meters
- 22 "screen from 0,9 to 1,1 meters
- 24 "screen from 1 to 1,2 meters
- 28 "screen from 1,2 to 1,4 meters
- 32 "Monitor / TV Screen from 1,4 to 1,6 meters
- TV 40 " from 1,7 to 2 meters
- TV 42 " from 1,8 to 2,1 meters
- TV 46 " from 1,9 to 2,2 meters
- TV 50 " from 2,1 to 2,4 meters
- TV 55 " from 2,3 to 2,6 meters
- TV 58 " from 2,4 to 2,8 meters
- TV 60 " from 2,5 to 2,9 meters
- TV 65 " from 2,7 to 3,1 meters
- TV 75 " from 3,1 to 3,6 meters
- TV 80 " from 3,3 to 3,9 meters
- TV 85 " from 3,5 to 4,1 meters
For a 4K TV instead you should sit closer to appreciate the best visual quality then the relationship between distance and size is the following.
40 to 45 " from 1,16 to 1,30 meters
46 to 50 " from 1,33 to 1,45 meters
51 to 55 " from 1,48 to 1,59 meters
56 to 60 " from 1,62 to 1,74 meters
61 to 65 " from 1,77 to 1,88 meters
66 to 70 " from 1,91 to 2,03 meters
From 71 " minimum distance 2,06 meters
