What is a Short Throw Projector? All You Need to Know

When it comes to projectors, all the talk usually centers around their range – how far they can throw, the size of the projector screen etc. But what about short throw projectors? What are they and how are they different from long throw projectors? In this blog post, we’ll be exploring what a short throw projector is and how they’re used, along with all the pros and cons so you can make an informed decision about which projector is best for your needs. So buckle up, because we’re about to go deep into the world of short throw projectors!

A short throw projector is a particular type of projector that can project images with great clarity at a very short distance. These projectors make it possible to receive an excellent quality image in a relatively small or confined space such as a classroom, office, or even home theater without having to place the projector far away from the screen. Typically, these projectors have an optical zoom system allowing the operator to shorten the distance between the projector and the screen by decreasing the size of the projected image.

There are debateable pros and cons associated with using a short throw projector. On one hand, many people argue that having a high-quality source of lighting for projection helps to eliminate environmental hazards resulting from using long throw projectors, such as shadowing, which can be distracting and reduce overall image quality. Others disagree and say that while short throw projectors do provide a good performance in shorter settings compared to long throw projectors, image quality tends to suffer when too much light is emitted into a small area and smaller pixels result in less detailed output.

Overall, short throw projectors offer an alternative option for situations requiring versatility, mobility and close-range viewing. The next section will explore some of the benefits of employing a short throw projector in different contexts.

Benefits of a Short Throw Projector

A short throw projector can be beneficial for a number of reasons. Many people choose this type of projector for tight spaces, where regular systems are more likely to cause shadows, beam interference, and other visual problems. With a short throw projector, the user can be closer to the projection surface. Not only does this help reduce shadows from the projector’s head, but it allows greater control over the placement of the image on the wall.

The short throw design also allows for brighter images with less lens distortion than standard projectors since there is less distance between the lens and the display surface. This means users can enjoy an image with brighter colors and more detail than a standard projector.

Installing a short throw projector also usually means fewer cables and easier set up than with a regular projector. This is especially useful in classrooms or meeting rooms where wiring can often be difficult or expensive to install or change later on.

Additionally, some short throw models may include multimedia speakers, network connections and other features that running media or interactive presentations much easier.

On the downside, while they might be relatively easier to set up, most short throw projectors will require a wide angle lens adapter to project onto larger surfaces, which may incur extra cost depending on what model you purchase. Furthermore, due to their compact size, many short throw projectors may not have as many ports or brightness capabilities as standard models.

In any case, it’s important to weigh all these benefits and drawbacks before deciding if an short throw projector is right for your needs. Now let’s explore how to prepare your space for a short throw projector setup.

Short Throw Projector Setup

When it comes to setting up a short throw projector, there are a few important considerations. First of all, the right environment or space is key. The room should be entirely dark and without significant reflection on walls or other surfaces. Picking a wall as the projection surface, rather than a whiteboard or digital display, is typically the best option for optimal image clarity and brightness.

In terms of placement, most short throw projectors can be installed closer to the screen, compared to standard projectors which require greater distance for a proper size image. However, these projectors benefit from some distance in order to maintain consistent brightness and quality of colors and shadows. The ideal distance between the projector and the wall depends on factors such as projector model, features, settings, zoom (throw ratio), aspect ratio and level of available ambient light inside the room. For example, an Epson LS500 laser short throw projector with an 0.24:1 throw ratio requires only 24 inches of distance in order to fill 11 feet of width.

On one hand, having to find the ideal spacing and distance is beneficial because it ensures that users can get the size picture they want with initial setup and minimal adjustments. On the other hand, this factor could be considered inconvenient since it might require measuring to achieve the desired picture quality for some particular spaces.

Having considered installation environment and placement details when setting up a short throw projector, next we will explore how to find the ideal projector placement for optimal picture quality.

Finding the Ideal Projector Placement

When it comes to finding the ideal placement of a short throw projector, there are several factors that need to be taken into consideration in order to ensure a successful viewing experience. A few of these considerations include the size and shape of the room, ceiling height and the projector’s position within the space. However, one of the most important aspects of finding the ideal placement is determining the appropriate throw distance.

The throw distance is the distance between the projector lens and the image projected onto a surface, and is measured in inches or centimeters depending on which type of unit you’re using. With short throw projectors, this distance can range from three to thirty feet wide and is essential for accurately calculating where your projector should be placed, as well as which angle ratio will work best for a given projection area.

For instance, if you are aiming to project an image onto a wall that’s fifteen feet from your projector lens, then you need to consider what angle ratio would produce the desired aspect ratio for your image. Additionally, since short throw projectors work best when their lenses are close to the screen, you would need to determine how far back your projector should be placed relative to that wall in order to achieve this ratio. The right angle ratio ensures that all images between two points (projector lens and wall) remain true representations of one another; any miscalculation in this area can cause serious distortion in projected image.

The amount of throw distance needed will depend on individual viewing needs; those wanting larger projections may require more length than someone with smaller images planned. It may be helpful to use different tests with different distances in order to discover which size works best for your setup. Ultimately, achieving the right balance between throw distance and angle ratio is key when positioning a short throw projector for optimal results.

Now that we have discussed finding an ideal projection placement for a short throw projector, let’s discuss how understanding angle ratio and throw distance is crucial for obtaining accurate image display in our next section.

Angle Ratio and Throw Distance

Projector angle ratio is an important factor to consider when deciding on a short throw projector. This ratio determines how wide the image is projected by the unit, and it’s usually expressed as a two-number combination (e.g., 4:3). A low angle ratio number suggests that the projector has a wider-angle lens for wider images, while a higher angle ratio number means the image will be narrower. For example, a 16:9 angle ratio indicates that the projectors throw a wider image than one with an 8:7 angle ratio.

The other variable in choosing the best short throw projector for your needs is the throw distance. This determines how far away from the wall or surface you can place the projector and still achieve a high level of clarity from the image. The most common amounts of projection distance are between 2-6 feet; any further than that and you may no longer receive optimal clarity from the image. There are different schools of thought regarding short throw distances – some people prefer to place their projector closer to get an even wider selection of viewing angles, while others may be more comfortable with keeping their projector further away so as not to be blinded by it during use. Depending on your needs and preferences, you should be able to find one option or another that works best for you.

At this point, now that you know what to look out for in terms of angle ratio and throw distances when selecting the right short throw projector, it’s time to learn about what else you should consider when making your purchase. In the next section we’ll discuss important factors such as resolution, lumens output, contrast ratios and other specs that will help you make an informed decision when shopping for your new projector.

Selecting the Right Short Throw Projector

When selecting the right short throw projector for your needs, there are several factors to consider. From setting up an appropriate viewing space to selecting a projector with the features and performance capabilities you require, getting set up with the perfect setup can be overwhelming.

Firstly, you will need to determine the size of your viewing area. Short throw projectors usually have a much wider range of projected output options, meaning they can be used in larger or smaller rooms compared to traditional projectors. Because of this, you must accurately measure the size of your screen or wall where the projector will be pointed. Many models come with easy-to-use zoom and focus controls that make it easier to adjust the image size and focal length quickly and precisely. It is important to note that when selecting a short-throw projector model, you may need to factor in the distance between the projector and wall when determining what lens-shift settings may be necessary for your installation.

Now consider how bright your environment is. If you are going to use your projector in a dimly lit room then you don’t need one with very high lumens; however, if you are looking for a more versatile device that can handle whatever conditions might arise then it is best to go for something brighter. The type of lamp used is also important; most projectors use LED or laser lamps which offer greater brightness and better contrast than traditional bulbs but are typically more expensive.

Finally, decide whether you want any extra features such as wireless projection, keyboard/mouse support or 3D capabilities. Depending on your budget and requirements, some extra features can enhance your viewing experience while others may not fit into your budget or lifestyle.

Once you have taken these factors into consideration, you’ll have a better idea of what type of short-throw projector works best for you. By shopping around at different retailers and comparing models side-by-side, you can find something that fits both your budget and needs perfectly. With proper planning and research, selecting the right short throw projector doesn’t have to be daunting!

Now that we have discussed selecting the right short throw projector, let’s move on to discussing lens quality and focal length in our next section.

  1. A short throw projector can project images up to 80 inches on a screen or wall from less than 3 feet away.
  2. Short throw projectors are designed with lens technology that allows them to produce large images while maintaining a minimal footprint.
  3. Short throw projectors offer extra convenience, allowing you to move your screen or wall and place your projector closer without negatively affecting image quality or clarity.

Lens Quality and Focal Length

Lens quality and focal length are important specifications to consider when buying a short throw projector. The lens quality affects the sharpness, clarity, and overall image quality of the projected image. Higher quality lenses produce brighter, sharper, and crisper images with minimal distortion and maximum light output. They can also handle wider zoom ranges than lower quality lenses for larger, more versatile images.

Focal length is another important factor, as it determines how far away the projector will need to be placed in order to produce an image of a certain size. Short throw projectors have a smaller focal distance that allows them to project larger images from closer distances. For example, some short throw projectors can produce a 120-inch image from less than two meters away while a typical long-throw projector would need to be placed around eight meters away. This makes short throw projectors much more suitable for spaces with limited room or where the projector needs to be placed closer to the screen or wall for aesthetic reasons.

The tradeoff for shorter focal lengths is that shorter lenses tend to have higher levels of distortion and chromatic aberration. This can affect image quality and sharpness, so it’s important to make sure you find a balance between focal distance and lens quality before making a purchase.

The next section will focus on resolution, brightness and picture quality and how they relate to short throw projectors. Understanding these limitations will help you narrow down your search for the perfect projector for your needs.

Resolution, Brightness and Picture Quality

When deciding what short throw projector is best for your needs, resolution, brightness and picture quality should be taken into consideration. Resolution is the number of pixels displayed on a screen or wall, measured horizontally by vertically. It’s important to remember that many projectors with the same resolution may display different levels of sharpness due to native resolution. Native resolution dictates how many pixels the projector is actually trained to produce which can affect image sharpness and clarity.

Brightness determines how clearly a projected image will be seen in various lighting conditions. Most short throw projectors range from 2500 – 5500 lumens, but this largely depends on what amount of light can enter the room, as well as the size of the projected image. Although bright projectors are typically preferred, they also tend to be more expensive, so keep this in mind when considering budget.

Picture quality is an overarching measure that considers both resolution and brightness together. Higher quality pictures are often associated with higher price points due to things like better compatibility and extra image processors. This can limit the potential number of compatible devices you can use without an adapter which is yet another factor to consider when choosing a projector. Ultimately total picture quality relies heavily on the environment in which you are using the projector so it’s important to take your intended usage scenario into consideration before buying a projector.


The last aspect to consider when selecting a short throw projector is its conclusion – what features does it have with respect to power consumption, portability, etc?


Short throw projectors offer a range of benefits, from creating more usable space in a room to providing impressive image quality. On the other hand, their small size and lack of optical zoom can be difficult to work with for some applications. Ultimately, choosing whether to go for a short throw projector or traditional projector comes down to individual needs and preferences. Those needing extra screen space or usability could benefit greatly from short throw projectors, while those looking for maximum versatility should opt for traditional projectors with optical zoom. It’s important to weigh both sides of the argument and make an informed decision based on the specific application.
