Short-Throw vs Long-Throw Projectors: How to Choose the Right Throw Distance

"Throw distance" is simply how far a projector needs to sit from the screen to produce a given image size — and getting it wrong is the single most common reason a projector installation disappoints on day one.

Short-throw projectors

Designed to sit close to the screen (sometimes under a metre away), short-throw units are ideal for compact classrooms, tuition rooms or spaces where a ceiling mount far from the wall isn't practical. They also reduce shadow interference when a teacher stands near the screen.

Long-throw (standard) projectors

Standard-throw projectors need more distance behind the lens to fill a large screen, which suits bigger halls, auditoriums and home theatres with more room to work with.

How to calculate what you need

Every projector's spec sheet lists a throw ratio (distance ÷ screen width). Multiply that ratio by your desired screen width to get the required mounting distance — then check it against your actual room dimensions before ordering.
