Projector Screen Dimensions: How Big Of A Projector Screen Do I Need?

Projector Screen Dimensions: How Big Of A Projector Screen Do I Need?

No one doubts the importance of having a projector screen. The question now is, how do you choose the best one for yourself? There are several things you have to consider when buying, one of which is dimension.

Projector screens come in a lot of different dimensions. So many, you may be confused about which one to get. You may wonder, “What are the best projector screen dimensions?”

The answer depends on what you are using your projector screen for. The different dimensions were made with specific reasons in mind. Once you determine what you’ll use your projector screen for, you will know which one is the best for you.

Let’s say you want to give a presentation, which is the best size for that? Or perhaps you’re building a home theater, what dimensions should you look for? Let’s have a look at which dimensions work best for every situation.

What Is The Best Projector Screen Dimension?

Before you decide which dimension of projector screen to get, it’s very important to know your projector first. What dimensions does your projector use? Whatever the answer, you should get the same dimensions for your screen.

The last thing you want is for your projection to get out of the screen. This won’t look good, and it can be very distracting for the viewers.

Another thing you don’t want is for there to be empty spaces on your projector screen. Again, this doesn’t look good and can be distracting. You want your projection to fill the entire screen without leaking anywhere.

That said, let’s take a look at the 3 most common projector dimensions. This will give you a good idea of which one will work best for you.

4:3 Video Screen

One of the most common dimensions of projector screens is the 4:3 video screen. We use these a lot, especially in office and classroom scenarios. This is the best dimension for presentations and lessons.

The advantage of the 4:3 screens is that they don’t take up a lot of space. When you are setting up a projector, you’ll find that width is a bigger problem than height.

You’ll find that space is hard to find, but the height of the ceiling won’t be an issue.

This is why the widescreens can often be difficult to set up. Whereas the 4:3 screen is a lot easier. If you want to have big projections, this dimension will make things easier for you.

This is why 4:3 video screens are used for presentations in classrooms, offices, etc. This type of screen makes it very easy for you to pull it out and use it at any time.

16:9 HDTV Screen

The main problem with 4:3 screens is that they don’t match most monitors today. 4:3 is generally considered a classic dimension. Today, most of our monitors are wider than this.

Perhaps the most common dimension for monitors today is 16:9. There’s a big chance that you’re reading this on a 16:9 laptop screen right now. This is why 16:9 projector screens are a great choice.

You can see the reason why 16:9 is preferred over 4:3 nowadays in this video:

When you use a 16:9 projector screen, most projectors will completely fill this. There won’t be any white areas. Nor will the projection get out of the screen anywhere.

This is why if you are going for a home theater, 16:9 is a great choice for you. The problem with using 4:3 for home theaters is that you’ll have to make the projection quite small. If you don’t, the wide dimensions of movies won’t fit into the screen.

2.35:1 Ultrawide Screen

The last of the common dimensions we’ll look at is the 2.35:1 ultrawide screen. This takes the 16:9 a step further by going a lot wider. You may be wondering what the purpose of this extreme width is?

It’s for movies and television. A lot of times, when you watch movies on a 16:9, there are going to be black bars above and below the film.

This is because most movies today use a very wide aspect ratio. They do this because this produces an amazing cinematic effect. Have you ever noticed how almost all movies are shot this way?

This is called an anamorphic effect. You can see this very clearly in this video:

This is why if you want the film to fill the entire screen, go for a 2.35:1 ultrawide. You won’t get any black areas at all, and this will create the best movie-watching experience.

What Is The Typical Size Of A Movie Theater Screen?

We can build our own home theaters, but we can never replicate a movie house experience. The main reason for this is because of how huge the screens there are. They are bigger than any projector screen you can get.

As you step into a theater, have you ever wondered how big these screens are? Not every movie screen has the same size. There are no standards.

That said, most movie theater screens measure 50 ft. wide. Now that is huge. These are the sizes needed to entertain everyone in the theater.

As for height, screens that reach 50 ft will be around 21 ft tall. This is because movie houses use the 2.35:1 ratio. They use this because, as you already know, 2.35:1 is the best proportions for movies.

What Is The Largest Projector Screen Size?

50 ft is way too large for ordinary projector screens. So what is the largest projector screen you can get for your home theater?

There are some huge screens in the market today. It’s easy to find screens that stretch 200 inches long.

And that’s not even the largest screens there are. Some screens go even further to 300 ft., such as this one:

But before you go and get the biggest screen you can buy, it’s important to check your projector first. These giant screens only work with good projectors. If your projector doesn’t fit in this category, you’ll get very low-quality images.

When it comes to projectors, it’s not always the bigger the better. You also have to consider the room you’re in, and how many people are watching. With these in mind, you’ll often find that you don’t need the largest projector screen you can get.

How Do You Measure Your Projector Screen?

Measuring your projector screen is very easy. All you have to do is take a measuring tape and measure the width and height.

Finding the ratio of your projector screen though is not quite as easy. To find this, you will need some basic maths.

Knowing the ratio of your projector screen is very important. It’s important to know this so you can get the right projector. To calculate this, all you have to do is measure your screen and reduce the ratio to its simplest form.

Doing this will show you whether you have a 4:3, 16:9, or a 2.35:1.

If you don’t want to do maths, there’s no need to worry. There are several tools online which can help you with this. With these tools, you only have to input the width and height and it will calculate the ratio for you.

This way, you will always know which ratio your projector screen has.

16:9 Vs. 16:10 Ratio

Another common ratio you’ll come across is the 16:10. It may seem quite odd to have this since it is very close to 16:9. And you may be wondering what the difference is, or which is better.

16:10 used to be the standard size for monitors. However, in recent years, this has changed to 16:9.

If you ask which is better, there is no definite answer. 16:10 allows you to project more on your screen. If you’re showing a presentation where you scroll down, this may be helpful.

16:9, on the other hand, is a lot more common. Most monitors are in these dimensions, as are most videos. That’s why with this ratio, you can fill up the screen completely.

It all boils down to preference.


Projector screens will enhance your presentations and home theaters tremendously. Even when they aren’t the perfect dimensions, it is still a lot better to have one.

That said, when you use a projector screen with the perfect dimensions, you’ll get a much better experience. And with this information, you now know the three most common dimensions around. You now know which ones are the best for your activities.
