Short Throw lamp-free projectors are great at delivering a big picture in small spaces. In order to create a 100-inch image, only 3-4 feet of throw distance is required. They’re cheaper than Ultra Short Throw alternatives, but there’s a reason for the price difference. Short Throw projectors struggle to work with anything other than a perfectly flat projection surface – and they aren’t compatible with any type of ALR (Ambient Light Rejecting) materials.
Ultra Short Throw projectors are even more ideal for providing big experiences in small areas – requiring only 3-20 inches of throw distance to create 100-inch images. Their flush design eliminates shadowing too, allowing them to deliver more immersive learning sessions. However, Ultra Short Throw projectors also rely on flat projection surfaces – and while CLR (Ceiling Light Rejecting) materials are available, their sizing is somewhat limited.
