The distance between the TV screen and your sofa is an essential question to fully enjoy your moments of relaxation in front of your favorite movies, series, and shows. Indeed, a distance that is too short or too long can have an impact on visual comfort, as well as on image quality. In this article, we will give you some tips to determine the ideal distance based on the size of your screen.
Why consider the distance between the TV screen and the sofa?
There are several reasons why it is essential to choose the distance between your television screen and your sofa carefully.
Visual comfort
Firstly, an inappropriate distance can be a source of visual discomfort and lead to persistent eye fatigue. If you are too close to the screen, you will constantly have to move your eyes to follow the action, while a distance that is too far can force you to squint to discern details.
Image quality
Furthermore, the distance will also impact the quality of the image you see. If you are too far, you will not fully benefit from the advantages of high definition image, while if you are too close, you may see individual pixels that make up the image.
Immersion
Lastly, the distance between the screen and the sofa also plays a role in your immersion in the world of the movie or series you are watching. A distance that is too great can create a feeling of disconnection, while a distance that is too short can cause image distortion.
How to calculate the ideal distance based on screen size?
There are several methods to determine the optimal distance between your TV screen and your sofa based on the screen size.
The 3-4-5 rule
The simplest method is the "3-4-5" rule, which involves multiplying the screen size (diagonal) by 3, 4, or 5, depending on your personal preferences and the type of screen.
For example, if you have a 40-inch screen:
- For a minimum distance: 40 x 3 = 120 cm;
- For a maximum distance: 40 x 5 = 200 cm.
This method is particularly suitable for HD and Full HD televisions.

THX recommendation
THX, the company founded by George Lucas to ensure a quality audiovisual experience, also offers a method to calculate the ideal distance.
According to them, the optimal viewing angle should be between 26 and 36 degrees. For a 4K screen, for example, the recommended distance would be:
- For a 26-degree angle: (screen size / 1.63) x 100 cm
- For a 36-degree angle: (screen size / 1.16) x 100 cm
Manufacturer recommendations
Finally, you can also refer to the recommendations of television manufacturers. Some offer distance guides based on the size and resolution of their models.
Do not hesitate to check the website or user manual of your TV to obtain this information.
Adjust the distance to your needs and constraints
Although the previous methods provide indications on the ideal distance between your sofa and your TV screen, it is important to consider your own needs and constraints, such as the size of your room, the position of your sofa, or your viewing habits.
Consider the size of your room
The distance between the screen and the sofa should be adapted to the size of your room. If your living room is small, you may need to compromise between the screen size and viewing distance.
In this case, do not hesitate to opt for a wall mount or an adjustable TV stand that will allow you to adjust the distance according to your preferences.
Adapt the distance to your viewing position
The ideal distance also varies depending on your viewing position. If you are often lying on the sofa to watch TV, consider adjusting the distance to avoid reflections and ensure an optimal viewing angle.
Consider your viewing habits
Lastly, remember that everyone has their own preferences regarding viewing distance. Some people prefer to be closer to the screen to enjoy an immersive experience, while others opt for a greater distance to preserve their visual comfort.
Do not hesitate to experiment with different distances to find the one that suits you best.
