What is an ideal TV-size calculator?

An ideal TV-size calculator is essential to help you find the best TV screen size based on your seat distance and recommended viewing angle to provide the best viewing experience.

How do you measure a TV's size?

When describing the size of a screen, it is typically measured diagonally in inches. The current standardized aspect ratio for high-definition television (HDTV) is 16:9, a widescreen format suitable for viewing video and entertainment content.

16:9 ratio sizing information
Standard TV has a 16:9 aspect ratio.

When deciding on the size of your TV for your room, relying solely on the diagonal measurement may not be sufficient. Our screen size calculator can help you determine the rest of your television's dimensions.

What is a TV's Field of View?

A TV's field of view (FOV)[1] is the visible area that can be seen on a TV screen within your line of sight. It is typically calculated by measuring the angle between the viewer's eyes and the edges of the screen. When watching from the same position, a large TV provides a wider field of view than a smaller one, resulting in a more immersive experience.

How does TV size affect your field of view?

When choosing a television, the screen size must be considered. The size of the TV directly affects the amount of visual information that the viewer can perceive. A larger screen can provide a more immersive and engaging viewing experience, but only if proportional to the viewing distance.

The Society of Motion Picture and Television Engineers (SMPTE) recommends a field of view of 30 degrees for optimal viewing of different types of content. For those seeking a more immersive experience, THX suggests a broader field of view of 40 degrees. This can enhance the viewing experience and make the content more engaging and immersive.

TV Size and Field of View Relationship
As the size of the TV increases, the field of view becomes more expansive.
