Short Throw Technology: A Guide to Understanding and Maximizing Its Benefits

Short Throw Technology is used to define a projector that is capable of projecting a 100” image from a distance of fewer than 9 feet (around 3 meters).

The earlier projector models used long throw technology which required the projector to be set at around 8 feet distance from the projecting screen. However, interruptions and shadows are created on the projecting screen when people or objects move in front of the lens.

Short throw lessens this problem by decreasing the distance between the projector and the screen so that a clear image of 100” can be obtained with fewer disruptions.

This article is a complete guide to understanding what short-throw technology is, its advantages, applications, and ways to maximize the benefits you may receive from it.

What is Short Throw Technology?

Short-throw projectors are advanced projecting devices that can easily project a clear 100” image using lesser space. Essentially, you will not be needing a huge space to present something to a handful of people. Short-throw technology is an upgraded version of long-throw technology that has proven quite handy for schools and businesses.

Then, there are ultra short throw projectors (UST projectors) which are advanced short throw projectors. These projectors can produce a clear 100” image with its lenses as near as 3 to 20 inches. A standard projector employs a mixture of lenses, mirrors, and LCD screens to project a picture. 

How does short throw technology work?

Short-throw projectors are designed to be nearer to the projection screen with the help of a chip that basically modifies the image’s geometry. The upgraded modification enables the angled projection to appear normal and rectangular on the screen.

Short-throw projectors generate excess heat in comparison to long throw ones due to the extra processing. The short throw ratio falls between 0.4 to 1. The throw ratio indicates that for each foot the projector is set back from the projection screen, the image projected by it will enlarge by 1 to 2.5 feet.

Difference between short throw technology and traditional projection technology

The only major difference between these two is the distance factor. Long throw projectors are supposed to be kept at a greater distance from the surface, while short throw projectors are supposed to be placed closer.

So, if you are planning to put up a projector in a large space like an auditorium or a theater, you could use a long throw projector.

On the other hand, if your space is smaller, you should go with a short-throw projector. Long throw projectors are also less expensive than short-throw ones.

Advantages of Short Throw Technology

Short throw technology, being an advanced innovation, has a number of advantages. Anyone who is in a dilemma on whether to purchase a short throw LED projector should be aware of all the benefits the projector will bring to the table.

#1. Space saving

This is probably the biggest advantage of short-throw technology. You can save up a lot of space because short throw projectors and ultra-short-throw projectors both can create clear images at a small distance from the screen.

#2. Improved Image Quality

You definitely do not want a projector that gives you blurry or unclear pictures. Resolution is a big deal and short throw technology got it for you. Modern 3LCD technology makes sure that every frame displays one hundred percent of the RGB color data. This provides a good color gamut and brightness but without the traditional rainbow effect or brightness problems associated with other projection methods.

#3. Increased Flexibility and Usability

These are not limited to specific uses. You can use a short-throw projector anywhere and for any purpose. Hence, it has high flexibility associated with it and has high usability. The installation is also quite simple. You do not require a lot of cables or labor. You can simply mount it on the wall or place it on a surface nearby.

#4. Lower Maintenance Costs

Installation of short throw projectors is simpler and inexpensive since it cuts down on labor and excessive cables. Lamp replacement and filter costs may add up as you use the projector, but it is nothing grave. 

#5. Better Sound Quality

Short throw projectors typically feature better sound with larger speakers due to the wide area available for installing huge speakers.

Applications of short throw technology

Although short throw projectors are flexible and can be used in any setting, here are some fruitful and major applications of short throw technology:

  • Home theaters
  • Classrooms
  • Conference rooms
  • Gaming rooms

Choosing the right short throw projector

Short throw projectors come in many varieties. Each version is especially beneficial for different purposes. Before you choose your model, you should evaluate some factors which need to be considered.

Factors to consider


Before choosing a short throw projector, you should be aware of the size of the screen, the weight of your projector, and the distance from the screen. There are projectors of different sizes designed for different needs.


Higher lumens produce brighter images. It is generally recommended that a projector with 1500 to 3000 ANSI lumens is purchased. However, home projectors perform great at 2000 ANSI lumens.


Projectors that are large have enough space for installing large speakers which can help you achieve better audio quality.


Whether you want your wall mount your projector or ceiling mount it is going to play a big role in which projector you should be choosing.


A projector’s light source decides its lifespan. Modern laser projection devices or LEDs are very much energy-efficient and may last for thousands of hours. 

Types of Short Throw Projectors

Data loss prevention (DLP), Liquid-crystal display (LCD), Laser, Liquid Crystal Technology on Silicon (LCOS), and Light-emitting diode (LED) are the five primary kinds of short throw projectors currently popular on the market. 

  1. Digital Light Processing (DLP): DLP uses a chip made of microscopic mirrors as well as a spinning color wheel that generates an image.
  2. Liquid-crystal display (LCD): These projectors use liquid crystal displays instead of physical moveable parts, unlike DLP projectors
  3. Light-emitting diode (LED): LED projectors are a separate breed. These are DLP technology or LCD technology with LED light sources.
  4. Liquid Crystal Technology on Silicon (LCOS): LCOS is a kind of DLP-LCD hybrid. LCOS uses liquid crystal chips paired with a mirrored backing. 
  5. Laser: Laser projectors differ from lamp-based ones. They opt for solid-state lasers instead of lamps for their light source.

Top brands and models

Innovation is a never-ending saga. Better and newer models of short throw projectors keep entering the market. Here are some latest hits.

  • Epson EpiqVision Ultra LS800 3-Chip 3LCD Smart Streaming Laser Projector

Tips for choosing the right Short Throw Projector for your needs

  • Firstly, before choosing a projector, make sure you know the factors that need to be considered (which are discussed above).
  • Secondly, be aware of the purpose of the purchase. Different models are made for different purposes, and you can only get the most out of your purchase if you know what you are gonna be using the projector for.
  • Thirdly, be aware of the budget. You want to get the best deal at the cheapest price. Be on the lookout and make sure you get your money’s worth.


Because of the shorter throw, light does not need to move across as much medium, resulting in more uniform image quality. Then there’s the benefit of being able to position it in a variety of rooms and settings.

Top-of-the-line short throw projectors are no longer confined to large rooms; they can now be found in small apartments as well. Short throw technology brings new projectors to consumers who were previously put off by prohibitive setup issues by removing the inconvenient distance requirement.
