How Short Throw Projectors Work

Most short throw projectors feature a throw ratio between 0.49 and 0.83. This means they can project a 100-inch (2.2m wide) image from only 1.1m away. Compared to standard projectors, this requires roughly half the distance for the same screen size.

Depending on the model, short throw projectors can produce images ranging from 50 inches up to 300 inches, providing flexibility for different applications.

Popular Applications

Short throw projectors are widely used in:

• Business exhibitions and trade shows with limited space
• Art exhibitions and digital installations
• Golf simulators
• Aviation and flight simulation
• Immersive gaming setups
• Education and training environments

Features to Consider

• Throw ratio (distance to screen vs. image size)
• Resolution options (HD, Full HD, or 4K)
• Maximum screen size supported
• Wireless projection capability
• Warranty coverage by brand and model

Screen Requirements (Important)

Short throw projectors require a flat and stable projection surface to deliver the best image quality.

For optimal performance, it is recommended to use:

• Fixed frame (tensioned) projection screens
• Tab-tensioned pull-down or motorised screens
• Or a perfectly flat wall surface

Standard non-tensioned screens may already have slight waves or surface inconsistencies. Due to the projection angle and wide-angle lens design of short throw projectors, these imperfections become highly visible, causing image distortion, shadowing, or artefacts on the screen.

Always ensure the screen or projection surface is perfectly flat and suitable for short throw projection to avoid image quality issues.
