Understanding the Basics of Rear Projector Screens
Before we dive into the nitty-gritty of making a rear projector screen, it’s essential to understand the basics. A rear projector screen is a type of screen that is designed to be used with a projector that is placed behind the screen. This setup allows for a more immersive viewing experience, as the projector is not visible to the viewer.
There are several types of rear projector screens available, including:
- Fixed screens: These screens are permanently mounted on a wall or frame and are ideal for dedicated home theaters.
- Manual pull-down screens: These screens can be pulled down when needed and are a great option for rooms with limited space.
- Motorized screens: These screens can be raised and lowered with the touch of a button and are perfect for high-end home theaters.
Planning Your Rear Projector Screen
Before you start making your rear projector screen, it’s crucial to plan the project carefully. Here are a few things to consider:
- Screen size: The size of your screen will depend on the size of your room and the distance between the screen and the seating area. A general rule of thumb is to choose a screen that is between 1/3 and 1/2 the width of the room.
- Screen material: There are several types of screen materials available, including white, gray, and black. The type of material you choose will depend on the lighting conditions in your room and the type of projector you are using.
- Frame design: The frame of your screen can be made from a variety of materials, including wood, aluminum, and PVC. The design of the frame will depend on the style of your room and the type of screen you are using.
Calculating the Screen Size
To calculate the screen size, you will need to consider the following factors:
- Room size: Measure the width and length of your room to determine the maximum screen size.
- Seating distance: Measure the distance between the screen and the seating area to determine the optimal screen size.
- Projector throw distance: Check the specifications of your projector to determine the minimum and maximum throw distance.
Using these factors, you can calculate the screen size using the following formula:
Screen size (diagonal) = (Seating distance x 0.625) / (Projector throw distance x 0.625)
For example, if the seating distance is 10 feet and the projector throw distance is 12 feet, the screen size would be:
Screen size (diagonal) = (10 x 0.625) / (12 x 0.625) = 83 inches

What is a rear projector screen and how does it work?
A rear projector screen is a type of screen designed for use with rear projection systems. It works by allowing the projector to project an image from behind the screen, rather than from the front. This setup provides a more immersive viewing experience, as the projector is not visible to the viewer.
The screen is typically made of a special material that is designed to reflect the projected image, while allowing light to pass through from the rear. This allows the image to be displayed on the screen, while minimizing any glare or reflections that might be visible to the viewer.
What materials do I need to make a rear projector screen?
To make a rear projector screen, you will need a few basic materials. These include a frame, a screen material, and a way to attach the material to the frame. The frame can be made from a variety of materials, such as wood or PVC pipe. The screen material can be a specialized rear projection screen material, or a DIY alternative such as a white sheet or a piece of translucent plastic.
You will also need some basic tools, such as a saw or a drill, to assemble the frame and attach the screen material. Depending on the design of your screen, you may also need some additional materials, such as a tensioning system to keep the screen material tight.
