Optimal Viewing Distance Calculator — SMPTE & Cinema Standards | TheaterOwl

Calculating THX Distance 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.

Como funciona

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.

Cenários de uso

• When simulating the installation space before purchasing new THX Distance equipment
• When wanting to optimize the performance of an existing home theater system and achieve professional-level tuning
• When needing to find a compromise for the best audiovisual experience within space constraints

Como usar a calculadora de distância de visualização THX

Insira a diagonal da sua tela em polegadas. A calculadora calcula as distâncias de visualização ideais com base nos padrões THX (36°), SMPTE (30°) e TV geral (22°).

A THX recomenda a distância mais próxima para uma experiência imersiva tipo cinema. SMPTE é para home theaters dedicados. O padrão de 22° é comum para TV casual na sala de estar.

Para telas de projeção, use o tamanho da imagem, não o tamanho da moldura física da tela.
