🎬 Projector Distance Calculator

Calculate the required projector distance from screen size and throw ratio, or find the screen size from distance.

How Throw Ratio Works

Throw ratio is the distance from the projector to the screen divided by the screen width. A throw ratio of 1.5 means the projector must be 1.5 times the screen width away. Short throw projectors (0.4-1.0) can be placed close to the wall, while long throw (1.5-2.5) projectors need more room.

Choosing a Projector

Measure your available distance first, then calculate the maximum screen size your space supports. Ultra-short throw projectors (below 0.4) can sit just inches from the wall, making them ideal for small rooms. Most standard projectors have a throw ratio between 1.3 and 2.0.
