Viewing Angle Calculator — Horizontal & Vertical Screen Angles | TheaterOwl

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.

Jak to działa

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.

Scenariusze użycia

• When simulating the installation space before purchasing new Viewing Angle 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

Jak korzystać z kalkulatora kąta widzenia

Wprowadź przekątną ekranu, proporcje obrazu i odległość oglądania, aby obliczyć poziomy i pionowy kąt widzenia.

THX zaleca ≥36° w poziomie dla immersyjnego kina. 20–30° to wygodny zakres do filmów. Poniżej 15° tracimy szczegóły.

Szersze proporcje obrazu zwiększają kąt poziomy, ale zmniejszają pionowy przy tej samej przekątnej.
