One of the most frequently overlooked factors when installing the home cinema system is the ideal distance to be watched by TV. Sinema and Television Engineers Community (SMPTE), this issue offers a simple and effective solution: 30 degree rule. This method guarantees the best results in terms of comfort and image quality, regardless of your screen size.

Method works as follows:

  • Interview Angle Calculation: Ideal viewing position should be determined to create a 30 degree angle between the corners of TV and your eyes -** Distance according to the size of the screen: about 1.5 meters for 55 inch TV, 1.8-2 meters distance for 65 inch TV is appropriate -View quality: The right distance helps to provide a smoother and natural image by masking pixel structure
  • Size and comfort of eyes: Optimal distance prevents discomfort caused by excessive or remote sitting from the screen
  • Innerability: 4K and high-resolution content makes it possible to evaluate the details best

This standard set by SMPTE is widely applied from professional studios to home environments. 30 degree rule is a scientific approach based on technological foundation, not only a recommendation. If your sitting position is changing or you think of different TV sizes, you can quickly calculate this formula based.

When you buy new TV, measure the size and viewing distance of your room before technical specifications. This simple step will give years more quality and comfortable viewing experience.
