# How much space do you need for a home theater projector?

Watching movies and playing games with a projector is great. Once you get used to the huge screen, it's even harder to see even on the biggest TVs. But before you buy a projector, make sure you have enough space.

The projector itself does not require much leeway. However, you must make sure there is enough space between the projector and the screen to achieve the desired screen size. With a bit of math, it's easy to figure out how deep your living room needs to be.

## Throw it Out

When exploring projectors, you'll get to know some specifications and industry jargon. The most important thing to watch out for is the "litter ratio", also called "throw distance". It calculates how far the projector must be from your screen. If the projection distance is "1

", you must place the projector a foot away from the screen to display a picture with a diagonal of one foot. If the projection ratio is less than one you can place the projector less than one foot away from the screen to make a one-foot diagonal image. If the projection ratio is more than one you must place the projector more than one foot away from the screen to create a 1-foot image.

Projectors are often listed with more than one litter ratio listed. This means the projector has a zoom wheel so you can resize the image. With several litter ratios nothing changes in our mathematics. You just have to calculate it again.

Here is the calculation to determine how far away your projector must be from the screen:

`  Throw Ratio X Desired Screen Size (inches or centimeters) = distance from screen (inches or centimeters) `

As an example we can do this Watch the BenQ HT2150ST . Suppose we wanted a screen size of 150 inches and need to know how far away the projector needs to be. This model has a throw ratio between 0.69 and 0.83, so our math looks like this:

`  0.69 (throw ratio) X 150 (desired screen size) = 103.5 (distance from screen) `
`  0, 83 (Throw Ratio) X 150 (Desired Screen Size) = 124.5 (Distance to Screen) `

Another way to determine how much space you need is to check the projector's marketing or model name , You see projectors that are advertised as "short distance," "ultra short distance," or perhaps no difference between the projections.

## What is a ultra short throw projector?

An ultra-short throw projector usually has a throw ratio of less than 0.4. This means that ultrashort projectors have a wide-angle lens that allows them to sit as close to a screen as possible. This is ideal for home theaters because you do not have to worry about mounting the projector and you do not have to worry about someone blocking a part of the image by walking between the projector and the screen.

I currently own a ViewSonic PX800HD projector with a throw ratio of 0.23. This means that I have a 175-inch screen because I set it up about 40 inches from my wall. And it is splendid . Here's our calculation for this projector: (19659007) 0.23 (Throw Ratio) X 175 (Desired Screen Size) = 40.25 (Distance from Screen)

Ultra-short throw projectors are great for anyone who wants to There are rooms on the floor, especially tenants, who may not be able to install the projector on the ceiling. It's also great if you want a huge portable "monitor": I've used my projector for movie nights in the backyard, shown photos at weddings and funerals, and everything in between. I do not need a long extension cable because the projector is already sitting near a wall.

Ultra short throw lenses are the most expensive to manufacture, so these projectors are equal in other factors such as resolution and brightness are the most expensive to purchase.

## What is a short throw projector?

A short throw projector is a bit further from the screen than its Ultra Short Distance cousin. Short shots usually have a throw ratio of between 0.4 and 1. This means that short throw projectors usually have to sit about five to ten feet away from the screen. You can mount short throw projectors on the ceiling or place them on a small table in the middle of a living room.

One of the better known short throw projectors is the BenQ TH671ST. This projector has a zoom wheel and has a projection rate between 0.69 and 0.83. To get a 150-inch image in your home theater, this projector must be between 103 inches (124 feet) and 124.5 inches (10.38 feet) from the screen. Although this does not work in the smallest apartments, it is not inappropriate in most homes. Here's our equation again:

`  0.69 (throw ratio) X 150 (desired screen size) = 103.5 (distance from screen) `
```  0.83 (throw ratio) X 150 (desired screen size) = 124.5 ( Distance from screen) [19659008]   One problem I had with short-throw projectors is that everything is powered up. The projector, my Xbox and other gadgets were on the lower part of a coffee table in the middle of my living room. I led a power strip with a long power cord under my couch and to the coffee table. From there, I placed the power strip and all power cables for my electronics in a   cable management box   and tried to make everything look as neat as possible. It worked somehow, but I'm much happier with my ultra-short litter, as I do not have to worry so much about cable management.
Short throw projectors are in terms of production costs between Ultra Short Throw and Standard projectors, which means they are also in the middle of how much you pay.

We use "standard" as a way to distinguish them from short or short projection projectors, but the word "standard" is probably not displayed in marketing. Standard projectors have a projection rate of more than one and therefore require the most space to create a huge image.

```  2.22 (Throw Ratio) X 150 (Desired Screen Size) = 333 (Distance From Screen) [19659008]  Remember, however, that there can be no more than 17 feet between the projector and the screen unless you want to block part of the image. You   can place most standard projectors  on a small table, but you would be happier if you mount them on the ceiling or put them on a shelf on the wall.
