The standard size of a picture in a projector is generally around 600 x 300 pixels. Projectors come in different shapes and sizes, so there isn’t one perfect screen size out there. To understand which size screen to buy, it’s important to know what you’ll be using the projector for.

Types Of Projectors

LCD Projectors are cheaper than DLP Projectors but are not as bright. They can be used for watching movies or even a PowerPoint presentation in a small room. The best offers of LCD Projector are from Epson and Panasonic technologies. The screen size of an LCD projector depends on the number of inches of diagonal distance between the front and back of the screen.

Image Size: The size of the image on the screen is usually around 300 x 600 pixels.

Contrast Ratio: The contrast ratio of LCD projectors is defined as the ratio between the white and black levels. The standard for LCD projectors is 300:1 that indicates the quantity of black to white respectively.

DLP Projectors

The DLP projector usually has a 4:3 screen ratio. With the standard ratio of 16:10, many screens will not provide a good image on this type of projector. You should therefore ensure that the screen you choose provides a 16:9 or 4:3 ratio.

Image Size: The image on the screen is 320 x 240 pixels.

Contrast Ratio: The contrast ratio for DLP projectors is 10,000:1 to 20,000:1.

3D Projectors

The 3D projector has an inbuilt lens that separates left and right images into two different parts. The standard 16:9 or 4:3 screen ratios will not provide a good image of these projectors.

Image Size: The image size is generally around 600 x 400 pixels.

Contrast Ratio: These projectors usually have a contrast ratio of 100,000:1.

Digital Projectors 

Digital projectors can run on a flat screen and offer edge-to-edge viewing. You can adjust the size of the image to your requirements. These machines use a digital sensor that does not require a projector screen at all. Digital projectors usually have high contrast ratios up to 1,000,000:1. They are ideal for business presentations as they offer no distortions such as shadows, colors and signs.

Image Size: The image size of these projectors is usually about 600 x 400 pixels.

Contrast Ratio: The contrast ratio for digital projectors is usually perfect for close ranges, but it decreases when the projector is used at a further distance from the screen. However, a high contrast ratio projector possesses a high brightness level.

Rear Projection Projector Screen

These projectors are designed to be placed behind the screen to reflect the image. You should note that this type of projector is not common in most homes since they are expensive. 

Image Size: The image size of a rear projection screen is usually around 600 x 400 pixels.

Contrast Ratio: This type of projector has three different types of ratios available: 

1. Normal ratio with a high contrast ratio. 

2. Normal ratio with a low contrast ratio. 

3. A special type of ratio that is designed for displaying high-contrast resolution images.

Buying Guide For Projector Screen Size 

Screen Size 

The most basic projector screen size is a 16:9 ratio. If you do not know your television screen size, you should factor this into your decision. However, if you do not have a television that has a 16:9 ratio, we recommend buying a digital projector.

Minimum Distance Between Projector and Screen

The optimum distance between the projector and the screen should be around 1 m. For smaller rooms such as an office or the bedroom, you can get away with a distance of up to 3-4m. However, for larger rooms such as the living room, you should keep a distance of only 1-2m. However, it is essential to note what type of projector you are using to get a screen that fits your specific needs. In most cases, projectors with a 4:3 ratio have a screen size of around 1.2 m. Larger screens with a 16:9 ratio should have a minimum screen size of 1.5m.

Aspect Ratio

The aspect ratio determines whether or not your projector screen needs to have special shaping to fit your particular projector. A standard projector screen has an aspect ratio of 16:9 or 4:3. Most projectors are flexible to work with either of these ratios. A projector with a wide aspect ratio will have a screen size of around 1.2 m and a 16:9 projector with the same aspect ratio should have a screen size of 1.5m. Larger screens can be purchased if you have a higher-end projector that entails an aspect ratio of 3:1 or even 1:1.

Screen Material 

The material determines the time required for cleaning the screen. There are various types of projector screens available on the market, each with unique characteristics.

1. Fabric Screen

Fabrics are the most common screen used with a projector and a digital signal processor (DSP). They can be cleaned using a damp cloth or a steam cleaner to remove dust, dirt and germs. Fabrics reflect light and reduce glare that is common in sunlight or from artificial lights such as LEDs.

2. Acrylic Screen

This screen is made out of a transparent, tough plastic material that is common in the car industry. These screens are ideal for areas with a lot of light. However, it should be noted that they may reflect light and create ambient heat that may affect the performance of your projector.

3. Perforated Screen

These screens offer great sound absorption and provide an ideal mirror-like image. They are common in boardrooms and large conference rooms where ambient lighting is controlled to ensure optimal image quality.

Projector Screen Shape 

The shape of your television usually determines the shape of your projector screen. Most projectors have an aspect ratio of either 4:3 or 16:9. Aspect ratios are usually determined by the width and height of the frame. There are some predetermined shapes for a projector or screen.

1. Square Projector Screen

A square projector screen is a 4:3 aspect ratio. It has a very high refresh rate that creates crisp and clear images. The square projector with a 4:3 aspect ratio is ideal for rooms with light to medium ambient lighting.

2. Circle Projector Screen

A circle projector screen is also known as an elliptical projector screen or ellipse, with an aspect ratio of 16:9 or 5:4 (called panoramic shape). In most cases, any projector with a 16:9 ratio will be able to fit into this shape. It is the most common shape used for rear-projection screens. These screens are ideal for controlling ambient lighting and can be used for indoor or outdoor use.

3. Rectangular Projector Screen

This term is used to describe a projector with a screen or projection surface that is rectangular in shape. It is usually larger than the typical square shape. The term “widescreen” came about when people found that the screens are wider than their conventional 4:3 television aspect ratio.

Projector Screen Type

There are various projector screens, including fixed-frame screens, roller screens, portable screens, and curved screens. Therefore, choosing the right type for your project to get the best possible image.

1. Fixed-frame Screens

The fixed frame is a 100-inch screen and most projectors can be attached to a fixed-frame screen. However, it is essential to ensure that you find the correct type of mounting for your screen. The sizes of fixed-frame screens range from 30 inches to 100 inches in length. These screens are ideal for projectors that require a single screen with a great zoom range.

2. Roller Screens

Roller screens are ideal for projectors with a wide-angle view. The distance from the projector to the screen should be minimal, and the screen should have minimal movement. It is essential to ensure that the screen has a wide enough angle of view to obtain a clear image.

3. Portable Projector Screens

Portable projector screens are ideal for projectors that have a space-saving feature. They have minimal space requirements and can easily move from one place to another. Also, you won’t require any further investment for mounting hardware if you use a portable screen. It can easily attach to the projector. 

Projector Screen Mount

Projector screen mount can work on different surfaces, including walls, ceilings, tables and others. Ensure that you get the correct type of mounting for your screen so that you can prevent your image from being blurred.

Throw Distance 

In projection, throw distance is the distance from the projector screen to the audience. The projector and screen need to have an optimum angle of view to project images clearly on the screen. To measure this, you need certain information about your projector and screen provided in the documentation and user manual. The optimum throw distance is usually between 30 and 80 feet.
