Whether incorporating a theater into your home or looking for a place to display presentations, a projector screen is helpful. While you can project onto a wall, the quality of the display will not be the same. Use this as a guide to place your 100-inch projector screen in the best area for your space.

A 100-inch projector screen has an overall size of 53.7 inches tall by 91.9 inches wide. If using a screen stand or pull-down mount, the screen will need more space. The screen’s diagonal measurement is 100 inches, and the view size ultimately depends on the screen’s aspect ratio.

What Is a Projector Screen?

A projector screen is the display surface onto which a projector projects its image. Screens are usually white but can also be grey. They are made of fabric stretched into a frame.

You can find a variety of materials in projector screens, including rubber, plastic, vinyl, spandex, and polyester fiber. The best options are typically spandex or vinyl; they are durable and stretchable enough to deliver a smooth viewing surface.

Each projector screen will have differences in design, size, and aspect ratio to meet the presentation demands of the buyer.

What Are the Average Dimensions of a 100-Inch Projector Screen?

Projector screens come in many different sizes. The most common are 60, 72, 96, 120, 140, and 170-inches. The size of the screen refers to the size of the diagonal measurement. The width of the projector screen is about 87% of the screen’s diagonal measurement.

A 100-inch projector screen is 53.7 inches high by 91.9 inches wide. The diagonal measurement of a 100-inch projector screen is 100 inches.

How to Choose the Size of a Projector Screen

The space available where you want to place your projector screen will determine the size to buy. The depth of the room where you will place the projector screen is important too. Consider how far you can sit from the screen and the ideal spot to mount or position the projector.

Choose a screen size that is equal or less distance from the closest seating point to the surface of the screen.

What’s the Projection Size of a 100-Inch Projector Screen?

As mentioned previously, 100 inches does not refer to the width or height of the projection screen. Instead, it refers to the diagonal length of the screen.

When purchasing a screen, it’s best to know the aspect ratio of the screen. The relationship between the height and width of a rectangle is what is referred to as an aspect ratio.

There are two commonly used aspect ratios: 16:9 and 4:3.

16:9 Aspect Ratio Screen

A 16:9 aspect ratio is usually used in home theaters, as it’s better when viewing movies. When determining the projection size of a 16:9 aspect ratio screen, you will need to find the width and height.

To determine the width, multiply the size of the diagonal by 0.8716. To calculate the height, multiply the diagonal by 0.4903. The projection size of a 100-inch screen and 16:9 aspect ratio is 87.16 inches wide and 49.03 inches tall.

4:3 Aspect Ratio Screen

A 4:3 aspect ratio is usually used in conference rooms, classrooms, and teaching settings. To determine the projection size of a 4:3 aspect ratio screen, find the width and height.

To determine the width, multiple the size of the diagonal by 0.8. Next, to determine the height, multiply the diagonal by 0.6. The projection size of a 100-inch screen and 4:3 aspect ratio is 80 inches wide and 60 inches tall.

What Is the Projection Distance of a 100-Inch Projector Screen?

The distance from the projector to the projector screen will determine the size of the image. The image size will increase the farther the projector is from the screen. However, that can vary based on zoom factor, aspect ratio, and other settings.

When determining the viewing distance, you will need to take these things into consideration:

  • The screen size 
  • The measurement or distance between the projector and the projector screen
  • The distance from the lens center to the bottom of the image when the lens is in the highest position
  • The measurement from the lens center to the bottom of the image when the lens is in the lowest position
  • The distance that the image moves from the center when the lens shifts all the way left or right

16:9 Aspect Ratio

A 100-inch projector screen with a 16:9 aspect ratio has a projection distance of 116 to 188 inches. The viewing angle is 165 degrees.

The offset from the lens center when the lens shifts to the highest position is 4.9 inches. Alternatively, the offset from the lens center when the lens shifts to the lowest position is 53.9 inches. The offset from the lens center when it shifts completely left or entirely right is 20.9 inches.

4:3 Aspect Ratio

A 100-inch projector screen with a 4:3 aspect ratio has a projection distance of 114 to 231 inches.

The offset from the lens center when the lens shifts to the highest position is 6 inches. When the lens shifts to the lowest position, the offset from the lens center is 66 inches. Lastly, the offset from the lens center when it shifts completely left or completely right is 25.6 inches.

Types of Portable Projector Screens

Portable projector screens are used primarily for mobile presentations when the presenter needs to move the screen to a location. Portable projector screens are available in several different design options.

Tripod Projector Screen

A tripod projector screen has a tripod stand that can mount to the floor. The screen is usually attached to the stand so that you can flip it open like an umbrella. These are best for those who have multiple presentations and need to set up and pack up easily.

Floor Pull-Up Projector Screen

You place a floor pull-up projector screen on the floor and then roll it up like a banner. The base in the casing holds the screen when not in use. When you’re done with the screen, you release it back into the casing for easy cleanup.

Double-Stand Outdoor Screen

A double-stand outdoor screen has two legs that hold the screen. These are best when you want to enjoy a movie or sports game outside.

Keep in mind that you will need to take into account the dimensions for the legs of the projector screen. For a 110-inch double stand projector screen, the overall height is 84.1 inches. The length of the screen is 101.8 inches and the height, not including the stand legs, is 60 inches.

Types of Wall or Ceiling-Mounted Projector Screens

Unlike portable projector screens, mounted projector screens are designed to be installed in a place for continuous use. Because you don’t handle them after each use, mounted projector screens have a longer lifespan. You can mount them to the ceiling or wall, depending on your personal preference.

Electric Projector Screen

An electric projector screen is the most advanced projector screen type as it functions with an electric motor. The screen can be electrically retracted into the casing when not in use. When you’re ready to use the screen, you can lower it with the push of a button.

Most electric projector screens have a remote control, but you can control some with a wall switch.

Manual Projector Screen

You can lower a manual projector when in use and roll it up manually when you’re finished with it. There is no remote control, so you must physically pull it up or down with its spring mechanism.

Fixed-Frame Projector Screen

Fixed-frame projector screens are for those who want the screen permanently installed, just like a TV screen. Unlike manual or electric screens that retract into a casing, the fixed screen is open all the time. People often use these types of screens for home theaters.

Tab-Tensioned Projector Screen

Tab-tensioned projector screens are not as common as other projector screens. These screens are designed to have a tensioning mechanism that stretches the screen tightly. The purpose of the mechanism is to reduce any wrinkles, achieving the perfect flat screen.

Where should I place my projector?

You can place a projector on most flat surfaces, and it will project an image. Of course, you can also mount it to the wall or ceiling if you want to keep it in a fixed location. When placing a projector, there are three things to keep in mind. First, the surface needs to be sturdy and level. Next, allow plenty of space around the projector for ventilation, so be aware of anything that could block the vents. Finally, the projector should be within reach of a grounded electrical outlet or extension cord. 


What’s the average cost of a home theater projector screen?

Adding a home theater to your home can take family movie nights to the next level. The total cost to complete this will ultimately depend on the quality of products you include. The cost of the screen will range in price based on size, material, and whether it’s pull-down or electrically powered. For an 84-inch projector screen, the cost can be as low as $110. For an electric 106-inch screen, the price is about $600. If you want to have the full-theater feel, a 92-inch, black theater screen can cost as much as $2,500.
