What Size Projector Screen For Church? An In-depth Guide With Useful Tips

One of the indispensable activities of the church is showing videos of hymns or bibles. A TV wouldn’t be a good choice in a large space with dozens of attendees.

The best solution right now is a high-quality projector. So, what size should you choose for a church projector screen?

A useful rule of thumb is ensuring that the screen height is between 10% of the distance from the device to the furthest viewer. Then you multiply that by 1.77 to get the horizontal size.

Besides the size regulation, you need to pay attention to the placement, brightness, and screen material to provide the best visual experience.

What Size Projector Screen For Church? 

The optimal screen size for churches will be between ⅙ and 1/10th the distance between the display and the back row of seats. You can use the aspect ratio to assist in finding the corresponding width.

The supporting formula shows that there is no standard size for church projector screens.

No church has the same architecture and space. The difference in area and interior layout will change your choice.

To get an idea of ​​the possible scenarios, let’s dig deeper into two common display sizes.

Cathedral view

Cathedral view

100 Inches Or Less

If your cathedral can accommodate a congregation of fifty people or less, that size is just enough. Everyone can see the display, even if they’re sitting in the back seat.

Even many people can use large LCD televisions here. This device is independent of ambient light and has sharper images.

Projectors for screens with a size of fewer than 100 inches have a reasonable price. You will have a lot of options on the market.

A useful tip is to choose devices with high brightness. It is also very suitable for projecting sentences and lectures in the classroom.

Greater Than 100 Inches

For churches or congregations that can accommodate hundreds of people, you will need a display over 100 inches in size. If the size is too small, people sitting far away will not be able to see the projected content.

You also need to equip a device with 4K quality to output clear images on the large screen. They ensure the image will not be broken or pixelated.

Please stay away from 1080p devices as they do not have enough resolution to provide the most realistic visual experience.

Where Should You Place The Screen? 

You will want to place the display in front of the attendees so that everyone can see the picture most conveniently. However, the placement is also related to the intended use.

To help all see the missionary, you can skip the first row as they can see him in person. However, you’ll want to ensure everyone can see what’s on the screen if you’re playing hymns.

Sometimes, you can arrange 2-3 screens throughout the cathedral to optimize the layout. People sitting on the right side will see the display on the left side more easily, and vice versa.

All projectors have a feature called throw ratio. This number represents the distance enough for the projector to emit light onto the surface.

Throw ratio contributes to determining the distance between the screen and the projector. The larger this value is, the further away you can get from the device.

Viewing Angles

Not every location has the same great viewing angle. Extreme viewing angles are areas that the human eye cannot see.

The viewing cone is the optimal area where all viewers can see the projected content on display. Light from the projection device onto the screen is limited to this area.

The further away from the viewing cone area, the more blurred the image and the worse the quality will be.

Choosing a suitable projection device in the church needs to pay attention to the appropriate viewing angle. Ensure a wide viewing angle of 160 to 180 degrees.

A good tip is that you can use two projectors and two or more screens to optimize viewing angles in the synagogue. It allows anyone to view the content.

You can refer to the video below to see how to set up projectors in the mosque effectively.

How Bright Should The Image On The Projector Display Be? 

Three factors determine the brightness of the projector image on display:

  • Image size.
  • The reflectance of display (gain).
  • Light power (lumens).

When these factors are combined, a measurement called the system foot-lamberts is created.

The most important factor that churches should pay attention to when buying projectors is gain. The larger this number, the higher the surface’s reflectivity will be.

So, more light will appear and make the image clearer in the eyes of the viewer.

However, you should not overdo it because the limited viewing angle will sacrifice high gain.

To overcome this problem, choose devices with high lumens. However, the cost for them will also be more expensive.

The larger the screen size, the more light has to spread over a larger space. Therefore, you will need to look for devices with high brightness and greater gain to balance the brightness.

With a 150-inch display, you should use a projector with 4000 lumens. It will increase to a minimum of 8000 lumens for presentations that are 200 inches or larger.

The space of the cathedral is also usually very bright and airy. Choose equipment with foot-lamberts over 60 ftL.

Does The Screen Make A Difference? 

Choosing a display screen is also an important decision if you want to have an effective show at the cathedral.

Let’s look at the two most popular options and analyze their characteristics.

Painted Wall

If the wall is used as a projection screen, the emitted image will be affected by the color of the wall.

Therefore, you may notice some differences in image, detail, and color when projecting on multicolored walls.

This option is quite popular with cathedrals with limited budgets. For best image quality, paint walls white and a smooth satin finish.

Matte and slightly rough paints will break the resulting image. Conversely, finishes that are too glossy can result in images that are difficult to see.

Projector Screen

A high-quality projector display should be your first choice in any situation.

You can choose from the popular white displays in schools and offices to project text or images. At the same time, the high-quality cinema grayscale display is suitable for effects and video projection.

If your sanctuary is small, save money by choosing miniature and foldable devices. It also helps optimize your usable space.
