How Much Space Do You Need for a Home Theater Projector?

Watching movies and playing games on a projector are excellent. Once you've got used to the giant screen, it's much harder to watch even on larger TVs. But before buying a projector, you must make sure you have enough space.

The projector itself will not need much room for maneuver, but you will need to make sure you have enough space between it and your screen to get the desired screen size. With a little calculation, it's easy to understand how deep your living room needs to be.

Throw it there

You'll see some specs and industry jargon when you start looking for projectors. The main factor to take into account is the "projection rate", also called "projection distance". You will use it to calculate the distance the projector should sit from the screen. If the projection distance is "1", you will need to place the projector at one foot of the screen to display a diagonal image of a foot. If the projection report is less than one, you can place the projector within one foot of the screen to obtain a diagonal image of a foot. Following this, if the projection report is more than oneYou must place the projector more than one foot away from the screen to produce an image of a foot.

You will often see projectors with multiple projection rates listed. This means that the projector has a zoom wheel, so you can change the size of the image. Having multiple projection ratios does not change our calculations; just calculate it again.

Here is the calculation to determine the distance between your projector and the screen:

Projection ratio X Screen size desired (inches or centimeters) = Screen distance (inches or centimeters)

For example, we can look at the BenQ HT2150ST. Let's say we wanted a screen size of 150 "and we need to know how far to place the projector. This model has a projection ratio between 0.69 and 0.83. Our calculation looks like this:

0.69 (projection ratio) X 150 (desired screen size) = 103.5 (screen distance)
0.83 (projection ratio) X 150 (desired screen size) = 124.5 (screen distance)

Another way to determine the space you need is to look at the marketing name or model name of the projector. You will see that projectors are advertised as "short-range", "ultra-short range" or perhaps without distinction of scope.

What's an ultra short throw projector?

An ultra short range projector usually has a projection ratio of less than 0.4. This means that the ultra-short projectors have a wide-angle lens that allows them to sit as close to the screen as possible. They are great for home theater because you do not have to worry about installing the projector, nor does anyone block a part of the picture by walking between the projector and the screen .

I currently have a ViewSonic PX800HD Projector, which has a projection ratio of 0.23. This means that since I've placed it about 40 inches from my wall, I've got a 175-inch screen. And his glorious. Here is our calculation, broken down for this projector:

0.23 (projection ratio) X 175 (desired screen size) = 40.25 (screen distance)

Ultra-short range projectors are perfect for people on the floor, especially tenants who may not be allowed to mount the projector on the ceiling. It's also great if you want a giant portable "monitor": I use my projector for movie nights, to show pictures of weddings and funerals, among other things. I do not need a long extension cord because the projector is already sitting near a wall.

Ultra-short lenses are the most expensive to make. Therefore, with factors such as equal resolution and brightness, these projectors are the most expensive to purchase.

What is a short throw projector?

A short throw projector moves away a bit more from the screen than its ultra short focal cousin. Short jets usually have a throw ratio of between 0.4 and 1. This means that short-throw projectors must sit at a distance of about five to ten feet from the screen. You can mount short throw projectors on the ceiling or sit on a small table in the middle of a living room.

One of the most popular short-throw projectors is the BenQ TH671ST. This projector is equipped with a zoom wheel and has a projection ratio between 0.69 and 0.83. To get a 150-inch picture in your home theater, this projector should be located between 103 inches (8.6 feet) and 124.5 inches (10.38 feet) from the screen. This will not work in smaller apartments, but it is not unreasonable in most homes. Here is our equation again:

0.69 (projection ratio) X 150 (desired screen size) = 103.5 (screen distance)
0.83 (projection ratio) X 150 (desired screen size) = 124.5 (screen distance)

A problem I had with short-throw projectors is to make sure everything is powered. The projector, my Xbox console and other gadgets were at the bottom of a coffee table in the middle of my living room. I spent a power strip with a long power cable under my couch and up to the coffee table. From there, I placed the power strip and all the power cables of my electronic components inside a computer. cable management box and tried to make everything as clean as possible. It worked a bit, but I am much happier with my very short range because I do not need to worry so much about cable management.

Short-throw projectors are located between very short focal length projectors and standard projectors in terms of production costs, which means that they are also at the center when it comes to the price to be paid.

What is a standard projector?

We use the term "Standard" to differentiate these projectors from short-throw or ultra-short throw projectors, but you probably will not see the word "Standard" in the marketing list. Standard projectors have a projection ratio greater than one and therefore need more space to produce a giant image.

the Optoma UHD60 The projection ratio is between 1.39 and 2.22; therefore, if you want to use it to get a 150-inch image, you should place it at a distance of 20 to 17 inches. screen. This requires a home cinema in depth, although it can work perfectly outdoors. Here is our decomposed calculation:

1.39 (projection ratio) X 150 (desired screen size) = 208 (distance from the screen)
2.22 (projection ratio) X 150 (desired screen size) = 333 (distance from the screen)

Keep in mind, however, that you can not have anything else within this distance between the projector and the screen unless you block part of the image. You can Place most standard projectors on a small table, but you would be happier if you put it on the ceiling or on a wall shelf.

Standard projectors are the cheapest type of projector to produce. They are also the cheapest to buy. Do not forget that some of your savings will go to support, extra long HDMI cables and other necessities.

So what is the best for you?

Determining the type of projector to buy depends on two factors: space and budget. The less space you have (that is, the shorter the run you want), the more expensive your projector will be. But you can also use more expensive, short-throw or ultra-short throw projectors because you can get a giant image almost anywhere.

Keep an eye on the offers too: I bought my ViewSonic PX800HD at almost 50% by having it refurbished. It was missing a power cable, but my savings on the projector did more than it was worth it.

No matter what space you have, you can get a giant screen with the right projector!
