One of the traditional shortcomings of projectors is always long throw distance. We are not becoming funny with what we are saying. Throw distance means the distance a device requires between its screen and lens for the given image size. For instance, older models required as much as twenty feet for a 100-inch display. And if we talk about movie theatres, they have a massive throw distance which can be tens of meters. Thanks to the lens technology of projectors, new models ensure what is known as short throw and even ultra-short throw. For example, a 100-inch screen from less than 3 meters or 9 feet approximately. As compared to previous iterations, this surely is a huge improvement. It allows you to have a big-screen viewing experience in confined and small spaces.

Moreover, there is less likely someone may walk in front of the lens a game console or bucket of popcorn. These types of projectors are ideal for home theatres because you have less space. You can get a good projector in USD 500 that has a short throw, compatible with your home space.

What a Short Distance Projector is

You can easily define a short-distance projector. If a product can show a 100-inch image from less than 3 meters or 9 feet, it is a short-distance projector. On the other hand, devices that require more than 3 meters of space to throw their 100-inch images, it is a regular throw. This is how you can categorize throw distance. However, the issue of the throw ratio is also present in this categorization. That means dividing the distance by the image size. Saying differently, how many feet of distance do you require for each foot of the screen? Traditionally, most projectors come with a throw ratio of 2, modern devices are capable of doing better.

Within the BenQ series of projectors, you can take the TK700STi, and TK700 as examples of low throw ratio models. The latter model requires 8.2ft for the image of 100 inches and comes with a throw ratio of 1.1 to 1.3. On the other hand, the TK700STi excels in the former with a throw ratio of 0.9 to 1.0 and only needs 6.5ft for a 100-inch image display. That is the reason, high-end BenQ projectors deliver low throw ratio and short throw distance while featuring true 4K HDR, and low input latency as is the case with the TK700, and the TK700STi. Unlike home cinema projectors and general use, they are custom-made for gaming purposes.

Pros

There are many benefits of having a short-throw projector. For beginners, it will be a catalyst for saving your space. For these projectors with a throw ratio of 0.4, a 4 feet wide display can be projected at just 1’7” from the projection origin. What this means is that you will not experience any annoying shadows when people watching are up to go to the bathroom. Since these devices are capable of projecting from such short distances, they are perfect for projecting from behind a screen, abating the possibility of them getting bumped by someone walking by.

Cons

These devices can get hot because extra power is required to convert rectangular pictures into trapezoids that are capable of projecting a rectangular at an angle. When they get hot, internal fans are on to cool down the unit which causes unwanted and annoying noise.

In addition to this, you can also experience image warping on an uneven surface then you may get from a long throw projector.

Which One is Better

Whether you require a short-distance projector or a long distance depends on numerous factors. Three important factors that you should keep in mind are the placement of the projector, the home theatre space, and the intended screen size. Characteristics of the space include room curvature and power source impact which kind of projectors such as a business projector or home theatre, you should purchase for your home theatre system? Besides that, whether you want to place it on the floor or mount the projector also determines your decision. Projectors with long and short throw distances work differently at different display sizes.

Choosing the right projector means balancing out your preferences, something that mostly depends on your personal taste and requirement. It is true that there is no ideal way of setting up a home theatre. But there is a perfect way for you. Following are some of the factors that impact your decision on whether you should buy short-distance throw projectors or not.

1: Placement

Firstly, you should decide where you want to place your projector. Moreover, you want it to mount on the ceiling, on the wall, sit on the floor, or rest on a shelf. Another thing that you should keep in mind is whether you have a room behind your projector. If yes, you might buy a translucent display and put your device behind it. Mounting your projector means that your device will project the image correctly every time. And not mounting gives you the option of making your article mobile. This is perfect for watching a movie on the side of your home on warm summer nights.

What is more, it is your projector’s throw ratio, and screen size that determine how much distance you should position your device from your screen. Multiply your display width by the throw ratio to know the proper distance you should put your projector. Moreover, it will also tell where you should put your viewing area, and whether you should mount the projector.

2: Screen Size

Your viewing area and ceiling height will dictate the size of your screen. If it is unconstrained by vertical space, you want the height of your screen to be 1/6th of the distance to the farthest part of your viewing area. However, the ceiling of the room is most likely to constrain this height. More than that, a screen should be three feet away from the floor to give you a comfortable viewing experience. By subtracting three feet from the ceiling of the room, you can get the maximum height of your screen. For maximum height, choose the lower of these two numbers.

On the other hand, the closest part of your watching area should be more than two screen heights away. In order to get the width, do multiply the screen height by the aspect ratio of your projector.

3: Space

One of the most important considerations of setting up a projector in a home is to determine the space you want to set it up. Curvatures of the room can have a major say in dictating the location of your projector and the projection surface. Further, power sources will also tell what kind of device you should buy for your home theatre. First thing first, you should make sure the projection surface does not catch glare from outside light. Surely, you will want to have your seating area across the projection surface while having room to have your speakers surrounding symmetrically.

If you have little space in your house, you should go with a short throw projector because the one with a long throw will not give you desired screen size. On the other hand, if you have ample space in your room or want to have a large screen size, a long throw projector is more suitable for your needs.
