What Is the Difference Between Standard Throw and Short Throw Projectors?
Over the past few years, the use of projectors in home theater systems and offices has become increasingly popular. Despite its growing popularity, many users still have doubts about the type of projector. This article describes the key features of standard, short-throw, and ultra-short-throw (UST) projectors. What Is Throw Distance? Simply put, throw distance is the measured distance that light must travel from the projector lens to the projection screen surface. A standard projection projector typically produces a 100-inch (16:9) image footprint at a projection distance of about 10 feet. Short-throw projectors can produce the same size image from less than half that distance (about 4 feet), while UST projectors can produce the same size image in just a few inches. 3 Different Projectors The three basic projector screen types are standard projection, short throw (ST), and ultra-short throw (UST). This article uses each type of projector to produce a 100-inch (16:9) image and discusses which materials are best. Standard or “long throw” projectors: Standard projection or “long throw” projectors are the most common type. Requires the greatest distance to produce an image. To produce a 100-inch (16:9) image, a projection distance of about 8 to 10 feet (244 to 305 cm) is generally required. It is versatile, cost-effective, and can be used in both the home and office. The main challenge when using a long-throw projector is how much space it takes up and the shadows it cast when people walk through the space between the projector and the screen. Short Throw Projectors: Short-throw projectors were developed to allow presenters to work closer to the projection screen without having the projector’s glare in the eyes. Another reason is that the tight space of many classrooms and educational facilities does not allow for enough projection distance for standard projectors. Needless to say, most short throw projectors are used for professional or commercial purposes. To produce a 100-inch (16:9) image, a short-throw projector usually requires a projection distance of about 3 to 4 feet (90 to 120 cm). It can provide a large picture even in small spaces. Ultra Short Throw Projectors: The ultra-short-throw projector is one of the newer concepts in projection technology. It still produces a huge image even though it is designed to be placed flush with the screen. They usually have reflective lenses to spread the light signal to a minimum distance. To produce a 100-inch image, ultra-short throw projectors typically require a projection distance of about 3 to 20 inches (8 to 50 cm). Since there is no chance of anyone passing between the projector and the screen, there is no chance of shadows. These projectors are already popular in businesses and educational institutions. However, they are gaining popularity in residential applications as manufacturers release cost-effective projector models. Which is best for you? When choosing a short or long-throw projector, there are certain factors that will ultimately influence your decision. Buying a long throw projector can be considered for the following reasons: *If you plan to project in a large room and need a larger screen. *If you prefer to have your projector project images taken from a distance, If you have a limited budget and want value for your money. Short throw projectors are a great choice for the following reasons: *If you prefer to place the projector close to a screen or wall to avoid accidentally bumping it. *If you have a more extensive budget and don’t mind paying more. Conclusion Standard projectors will fit into almost anything, but short-throw projectors require a flat surface with no strain but are more convenient to set up. For large, open spaces, traditional designs are best. Short-throw projectors are better suited for training environments, while Ultra Short Throw projectors are best suited for tight spaces.
