最佳观看距离计算器 — SMPTE & 影院标准 | 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.

工作原理

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.

应用场景

• 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

如何使用 THX 观看距离计算器

以英寸输入屏幕对角线尺寸。计算器将根据 THX (36°)、SMPTE (30°) 与普通电视 (22°) 标准给出最佳观看距离。

THX 建议使用最近的距离以获得沉浸式影院体验。SMPTE 适用于专用家庭影院。22° 标准则常用于客厅的休闲电视观看。

对于投影幕布，请使用画面尺寸，而不是幕布的物理框架尺寸。
