Calculate horizontal and vertical viewing angles for any screen size, aspect ratio, and viewing distance.
Calculating Viewing Angle is a fundamental and crucial step in home theater design. It is not just about measuring distance; it must be designed based on scientific evidence to maximize human visual perception limits and immersion. Incorrect settings can cause eye strain or fail to take advantage of resolution benefits. This tool complies with industry standards such as THX and SMPTE guides to provide the most precise data.
This system utilizes complex trigonometry and optical formulas. Based on the input variables (screen size, resolution, viewing angle, etc.), it simultaneously calculates the minimum distance where pixels do not appear clustered and the maximum immersion distance that fills the entire field of view. All results are reflected in real-time, suggesting figures optimized for the user's environment.
Insira a diagonal da tela, a proporção e a distância de visualização para calcular os ângulos de visão horizontal e vertical.
A THX recomenda ≥36° horizontais para cinema imersivo. 20–30° é confortável para filmes. Abaixo de 15° perde-se detalhe.
Proporções mais largas aumentam o ângulo horizontal, mas reduzem o vertical para a mesma diagonal.
