Which Specs do I need for Projector? Take Ratio
One of the simple things to learn when deciding between various types of projectors is the distance from the different models to throw. You can see this marked as long throw and short throw. Throw refers to the distance required to get the desired display size between the projector and the screen you 're projecting on (also called throwing the image).
The amount of distance needed for projecting a 100-inch image decides whether a projector is labeled as long or short throw. The lens used in the projector determines the throw distance, with the short throw projectors usually throwing a distance between 3 and 8 feet from the projector to the projection screen. The closer to the screen you push a long projector throw, the smaller the picture will become. A short throw projector that requires less distance to show the same picture and is a good choice for small spaces whereas a long throw projector is better for auditorium use.
Luminosity
Besides throwing distance, you'll need to be mindful of the brightness required for an successful show where you'll be using the projector. Brightness is expressed in lumens-the brighter the picture, the more lumens. For example, in a dark room 1,000 to 1,200 lumens will provide plenty of luminosity, whereas a room with windows or more ambient light would need 2,000 lumens or more.
