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.

Come funziona

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.

Scenari di utilizzo

• 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

Come usare il calcolatore della distanza di visione THX

Inserisci la diagonale del tuo schermo in pollici. Il calcolatore calcola le distanze di visione ottimali basate sugli standard THX (36°), SMPTE (30°) e TV generale (22°).

THX raccomanda la distanza più corta per un'esperienza immersiva tipo cinema. SMPTE è per home theater dedicati. Lo standard a 22° è comune per la visione TV in salotto.

Per gli schermi da proiezione, usa la dimensione dell'immagine, non quella della cornice fisica dello schermo.
