How to Calculate Projector Screen Size IOne of the common questions asked by the projector owner is how much screen size is ideal when they place their projector in the room.

Every projector owner wants to project a bigger image to get the best movie experience on the screen.

But how much bigger is the screen size, and how to calculate projector screen size when you have less knowledge about it?

Now every projector screen comes in multiple sizes, and every size will depend on where you will use your projector, either at business meetings or in your home.

If the room where you are going to place it has less space, then a smaller size with a distance of 4-5 feet is an ideal choice.

But if you are using it for business meetings where few people will view your presentation, then size with low dimensions can be ideal for you.

So, as someone with zero knowledge of calculating projector screen size, which works best for every situation?

Here is the calculator to help you select the appropriate projector screen size for your projector.

How to Calculate Projector Screen Size?

There are two types of screens: a retractable screen, mostly seen in classrooms or offices that come down automatically, and a fixed frame screen on the wall.

To get the accurate size, select the correct aspect ratio, measure your wall with tape, and measure the height and width.

Two aspect ratios are 16:9 and 2.35:1, widely used for a projection screen.

The below-detailed information will give you the right aspect ratio of the projector screen that fits your entertainment needs.

16:9

The 16:9 is HDTV format which is generally used if you watch lots of TV shows or sports content that are generally shot in 16:9.

The 16:9 will most probably fill the whole screen, but the problem with the 16:9 resolution is they produce a black bar below and above the images.

2.35:1

These have the ultrawide resolution, also known as cinemascope which is ideal for those who watch lots of movies or play games on their projector.

4:3 Video Screen

These projector screens are mostly used in schools, colleges, and churches because they can be taken anywhere as they don’t occupy lots of space.

Also, this type of screen can hang on the ceiling easily without doing a hard task.

How To Measure Screen Size? [Steps]

The first step to figuring out what size projector screen you need to understand some basic math.

In simple terms, when it comes to screens, one foot of distance is equal to one foot of width on the projected image.

To determine your projector screen size, you’ll need three main pieces of information:

  • Distance from the screen
  • Distance between you and the screen
  • Resolution/Width of a projected image

Determine the distance from the screen

The first thing that you’ll want to do is determine how far you are standing or sitting away from your screen.

For ease of measuring, this measurement will be in inches. So if you’re 5 feet away, your number would be ‘5’.

To get an accurate measurement, line up a string (measurement tape) against a wall with one end touching against the wall and measure along the string toward yourself until it lines up with your eyesight.

This gives you a straight line to follow when making similar measurements later. Make sure not to lean forward or backward while taking the measures.

Measure Distance Between You and Screen

Next, measure the distance between you and the screen in inches. Take this measurement in the same way that you took your original measurement.

For example, if you are 6 feet away from the screen but 3 feet to either side of it, take your number as ‘6’.

Determine the width of the projected image

Now that you have the measurements for both the length (in inches) and height (in feet) of your viewing space determine what size screen fits best into that frame.

The standard width-to-height ratio is 16:9 or 1.78 to 1. Still, many screens come in various ratios, including 2.35 to 1 for special theaters projector, an ultra-wide image reminiscent of the Cinerama panoramic format.

Now that you have all your measurements, it’s time to plug in numbers and find out what size projection screen will fit best in your space.

So if you are 6 feet away from the screen, 3 feet on either side of it, and using an image with a width-to-height ratio of 1.78 to 1 will give you a rough idea of the screen size requirement.

FAQ

What ratio is best for my home theater?

Different ratios work well in different rooms and with different types of content.

Like aspect ratios for television, most modern projection screens now have various ratios to accommodate everything from movies to video games.

The standard ratio is 16:9 or 1.78 to 1, but many screens also come with 2.35 to 1 and other variations, such as 4:3 (old school TV).

What is an ideal image size for my room?

Generally speaking, the larger the screen – the more immersive your experience will be. Larger screens also make it easier to ignore minor imperfections in resolution or contrast.

However, keep in mind that if you’re watching HD content with a projector at its native resolution of (1080p), the picture looks best if it’s playing true HD videos.

Q: Can I install my new projector and screen myself?

If you’re just putting up a projector on the ceiling, then yes! It’s not that difficult, and it’s possible to DIY these days, even if you’ve never done anything like this.

Screen installation gets a little harder when you don’t know how to measure the wall and find the exact center point (which I hate doing).

I suggest hiring a professional to do the work to mount the new screen without any problem.
