Optimal Viewing Distance Calculator — SMPTE & Cinema Standards | TheaterOwl

Calculate the optimal viewing distance based on THX (36°), SMPTE (30°), and Society of Motion Picture (22°) standards for any screen size.

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.

Comment ça marche

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.

Comment utiliser le calculateur de distance de visionnage THX

Saisissez la diagonale de votre écran en pouces. Le calculateur calcule les distances de visionnage optimales selon les standards THX (36°), SMPTE (30°) et TV général (22°).

THX recommande la distance la plus courte pour une expérience immersive type cinéma. SMPTE est destiné aux home cinémas dédiés. Le standard 22° est courant pour le visionnage TV décontracté au salon.

Pour les écrans de projection, utilisez la taille de l'image, pas la taille du cadre physique.
