A projector’s throw distance is the distance between the projector and the projected image on the screen. In other words, it is the distance that the image is “thrown”. Under the same focus, the projected image size and the throw are directly related to each other. The greater the distance is, the bigger the image is displayed. The projector position and the size of the image will depend upon your classroom configuration. Therefore, thinking about the room size will help you choose the appropriate throw. Below are 3 common throw distances.

Ultra-Short Throw: Virtually eliminates shadows and eye glare, this type of throw is seen from projectors installed on the wall, the ceiling nearer to a wall, or a table projecting downwards. Ultra-short throw projection refers to a distance between 0 to 4 feet away from projector to screen.

Short Throw: Providing large images while reducing shadows and eye glare, this type of throw is usually seen from projectors either installed on the wall or the ceiling closer to the wall — anywhere that is close to where the image will be projected. Short-throw projection generally refers to a distance between 3 to 8 feet away from the projector to screen.

Long Throw: Providing very large images, this type of throw is usually from projectors that are installed in the center of the ceiling in a large room.


In the market, projectors are offered in a wide range of brightness which is measured in lumens and lux. Lumens are the total amount of light emitted from the bulb. Lux is the amount of lumens in one square meter. The brighter the projector, the higher the lumen rating; and, all else being equal the more it will likely cost.

When selecting a projector, be sure that you look for the 2 lumens specifications of the device: color brightness and white brightness. These two ones can be different among brands, and it is necessary to have the color lumens measured and provided separately from the white one on the product information. However, some manufacturers give you only one lumen rating, and this figure can be understood as the white brightness of the projector. The color lumens may be as little as one-third of the given lumens.

Teachers working in classrooms with extreme brightness and having no intention to turn the lights off (as their students still need to write down on the paper) need to find a projector which provides higher brightness. For normal-sized classrooms, a projector with a minimum of 2500 lumens is best.


Resolution is the number of dots or pixels used to display an image. Higher resolutions mean that more pixels are used to create the image resulting in a crisper and cleaner image. The number combination like 1024 x 768 is the way the resolution is indicated. It means that there are 1024 dots horizontally across the display by 768 vertical lines of dots, and equaling 786432 dots used to show the image on the screen.

Each resolution comes with a separate aspect ratio. For example, XGA (1024x768 pixels, 4:3 aspect ratio), WXGA (1280x800 pixels, 16:10 aspect ratio) and HD (1920x1080 pixels, 16:9 aspect ratio). A projector with the minimum resolution of 800 x 600 will be suitable for your classrooms. And as many other things, the higher the resolution, the higher the price. If you can afford, an HD or 4K projector is a wonderful choice.


Most projectors now come to the market with built-in speakers. When being used for teaching or training purposes, the classroom size and noise in the room may make sound from those speakers not enough for the needs. These two things need considering when shopping for a projector. Adding some external speakers is a solution for a low sound output projector, but remember that not all projectors have audio output ports. So it is better for you to find out a product with loud built-in speakers.


What will happen if you have a new projector with HD resolution, loud built-in speakers but you cannot connect your computer or phone to it? It will take you more time to find out a suitable connecting way. This question shows the importance of connectivity when purchasing a projector.

Most projectors come with at the very least an HDMI port, which is great for laptop connection. Other types of connections include VGA, RCA, wireless, Bluetooth, and USB. The projectors have at least one of these types of connections. Connectivity also allows for centralized control within a tech department. If your school needs to perform maintenance or project over a network, then you want to be sure to purchase a projector that allows this connectivity.

Final words

Choosing a suitable projector that fits your budget and satisfies your requirements is not an easy task. However, if you set your requirements in priority and base on our given information, an affordable classroom projector meeting your requirements is soon to be found.
