Calculate your projector's mounting position. Find the exact throw distance needed to fill your screen. Compatible with long, short, and ultra-short throw lenses.
Calculating Projector Throw 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.
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.
Throw ratio is the relationship between the distance from the lens to the screen and the width of the projected image (Throw Ratio = Distance / Width).
No. Your projector's lens has a specific range. You must calculate the throw distance to ensure the image perfectly matches your screen size without digital keystone.
UST projectors have a very small throw ratio (usually under 0.4), allowing them to project a 120-inch image from just a few inches away from the wall.
