Are you going to buy a new projector? Do you think the projector you are going to buy is suitable for your room? Or have you checked the specs before you purchase the right option? If not then don’t forget to look for the size and throw of the projector. Now if you are thinking why do you have to focus on the throw of the projector? The main reason is that choosing the right projector will give you flexibility for placement. In return, you will get the clear image and right size for the image you have to view.

Before we dive into the discussion is about the difference between the short throw and long throw projectors and throw of projectors. Let’s first understand the projector’s throw distance. It is basically a distance between the image of the screen and the projector. In short, it’s the distance that image is viewed or you may say “throw”.

Different Throws Do Projectors Have And Differences Between Them

Two common types of throw distance come in the projector. One is the long throw and the other one is the short distance. Let’s discuss both one by one and find out which one is better for you.

Long-throw projection

You get large images with help of Long-throw projectors and know a good option to install in halls or auditoriums. Such projectors with Large throws are mounted on the ceilings in large size rooms.

Short throw

If you want a large image with fewer shadows and low eye glare, then short-throw makes a good choice. Such projectors are mounted on the ceiling or placed near the wall. They show a brighter view when placed in the distance between 3 to 8 feet from the screen.

We have described the main difference between these two types of projectors. Now let’s have a look at the key features that make these two types distinguish from each other.

Working of projectors

Short throw projectors have to project the image from a small distance so their working is based on the chip. It adjusts the image’s geometry. In this way, they project the view in an angled projection. Because of this modification, the image is brighter and sharp as compared to long-throw projectors.

Long-throw projectors show the best performance when placed some distance away from the screen. The lens directly projects the image on the screen. There is no specific mechanism for the projection of the image and it has straightforward projection technology.

Space requirement

Long-throw projectors require six feet or more space between their placement and screen. So, it can easily reach the 100* screen size limit. Thus, you can ideally place them in exhibition areas, large halls, or any large ground. The best thing about these projectors is that they make a perfect home theatre. You can enjoy a movie or watch documentaries on a large screen through this projector at your home.

In contrast, short-throw projects can create large images from a short distance. These are efficient to produce the 100* from 4 or fewer feet. So, for the small rooms and spaces, it makes a perfect match. where there is a lack of space, apartments or viewing area is less than the short-throw projectors are best. People can avail themselves of such projectors not only for watching movies but for playing games as well. It is because it delivers a larger image from less distance. The portable projectors are good to opt for home-usage.

There is less risk of accidental bumping and they are less likely to damage as you keep them on the table. Moreover, these save your space and you can add more items around it.

Throw Ratio

Another feature of the projector that you have to look upon is thrown. The short-throw has a throw ratio of 0.4 to 1. It means when you pull back the LCD projector by one foot then the image will increase 1 to 1.25 feet.

Long-throw projectors have a large throw ratio and it is more than one. The screen size of the image that is projected has a width smaller than a gap between the projector and screen. The long-throw type projectors are best for movie theatres. People can create a shadow with this type of projector. Long-throw projectors are installed six feet away from the screen. As on small space, the small image is projected so these are placed some distance apart from the screen.

Cost of projectors

One more difference that exists between the two projectors is the cost. The short-throw type needs a special lens. It is because these need to overcome the image distortion that can be present in the space different from a screen. Thus, these are expensive as compared to the long throw type. The latter type is cheap because these are easy to assemble, and need the normal type of lens to project a clear image.


The location of the projector plays a role in the image size is projected on the screen. For producing the 80 inches screen with projection, you have to place a projector about 92.7 cm from the screen. For achieving an appropriate width the long throw projector can be placed 240cm away from the screen.

Screen Size

One important factor you should not deny is the screen size. To have an appropriate screen size you have to determine the height of the ceiling and viewing area. Try to keep the projector 3 feet above the floor. To get the maximum screen size and dimension you have to subtract 3 feet from the total ceiling height. To get the width you need to multiply the aspect ratio with the projector as well as its height. In this way, you will get the optimum size of your screen.

Screen size can also be depended on the type of screen and the distance from the screen. So, you have to first determine the area and screen size to buy an appropriate projector to fulfill your need.

Brightness and resolution

It is another important factor that will reflect the quality of the projection on the screen. You can adjust brightness by adjustment according to the distance. You can adjust knobs for regulating the brightness. Moreover, brightness can be measured through the ANSI lumens unit. It is the amount of light that the projector produces. For using the small throw projectors you have to pick a projector that provides the highest unit. These are good for placement outdoors.

Remote control

Through remote control, you can manage your device very easily. It is best when you install your projector on the ceiling. For long throws projector, there is a need for the remote control so you can conveniently control the projector. The short-throw projectors don’t need the remote control as these are kept near to the screen so you can operate it manually. But the advanced type also comes with remote control for convenient control.
