If you have to buy a new TV or a new PC monitor, to decide the size we can not only think about the aesthetics, but also how far or near the screen can be compared to the position in which we are sitting.
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 image and spending more on a 4K resolution TV may be unnecessary depending on the size of the room and the distance you plan to sit on the screen.
In short, if you sit too close to a large TV with a lower resolution, you risk seeing individual pixels on the screen, thus ruining your vision.
Conversely, if you sit farther away from the screen and buy a 4K TV that is too small, you will not be able to enjoy the higher resolution and you will not be able to distinguish more pixels than a cheaper TV.
The key factor in the balance between screen size, resolution and viewing distance is called angular resolution which indicates the eye's ability 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 the details when they are at a certain distance from the screen and everyone can see the individual pixels if they approach too much.
Based on this information, you can use math to find the right distance to stay depending on the size of the screen or, in the same way, buy the TV of the right size based on the expected distance in the living room or bedroom.
On the Rtings.com website there is an interactive graph where you just have to move the cursors 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 Starico website 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 vision.
There is no absolute answer for the perfect TV size, but rather an interval in which a given size and resolution becomes the right one .
To use the graph, you must choose the viewing 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 is 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 optimally compared to an older 1080p 40-inch resolution TV, you should stay at a distance of 2 meters to not see the individual pixels of the whole.
If you buy a 65-inch 4K 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 calculator and the distance graph are exceptional tools that not only help you find the optimal size for the best viewing experience for TV and computer monitors, but also help you avoid wasting money when you go to buy a new screen.
Below is the table of the 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
- Monitor / TV screen 32 " from 1.4 to 1.6 meters
- 40 "TV from 1.7 to 2 meters
- 42 "TV from 1.8 to 2.1 meters
- 46 "TV from 1.9 to 2.2 meters
- 50 "TV from 2.1 to 2.4 meters
- 55 "TV from 2.3 to 2.6 meters
- 58 "TV from 2.4 to 2.8 meters
- 60 "TV from 2.5 to 2.9 meters
- 65 "TV from 2.7 to 3.1 meters
- 75 "TV from 3.1 to 3.6 meters
- 80 "TV from 3.3 to 3.9 meters
- 85 "TV from 3.5 to 4.1 meters
For a 4K TV you should instead sit closer to appreciate the best visual quality so the relationship between distance and size is as follows.
From 40 to 45 " from 1.16 to 1.30 meters
From 46 to 50 " from 1.33 to 1.45 meters
From 51 to 55 " from 1.48 to 1.59 meters
From 56 to 60 " from 1.62 to 1.74 meters
61 to 65 " from 1.77 to 1.88 meters
From 66 to 70 " from 1.91 to 2.03 meters
From 71 " minimum distance 2.06 meters
