Different Screen Sizes :
The projectors allow you to view your content on the bigger screen that is always large than the largest TV screen. However, the size of the projector’s screen varies from large to the largest so that you can choose from different variety of sizes.
Does the question then arise for what size projector screen do I need? The screens offer variety in sizes that are categorized in the following categories: HDTV (16:9), Square (1:1), Video (4:3), Widescreen PC (16:10), CinemaScope (2.35:1), and several other AV formats.
Format And Size Requirement :
The format and the size of the projector are needed to be understood for selecting the best and most suitable model. The perfect size of the projector depends on the projector model itself. before starting to look for the projector screen size, it is important to look for the aspect ratio that is the best starting point which then leads you to select the size.
Checking Height By Its Ratio :
The sole solution to look for the size is by getting the correct height of the screen by its ratio. The 4:3 video will be suited with the screen height that will be at least 1/6th of the distance from the screen. It is the best option to utilize in large venues.
When the projector of size 4:3 video is placed in the boardroom or classroom, it will require the screen height to increase to ¼ of the distance of the chair that is farthest.
The HDTV aspect ratio of 16:9 and widescreen aspect ratio of 16:10 requires the screen height that is equal to the 1/3 distance between the screen and the sittings. It depends on viewing choice as well.
The Cinema Video with the aspect ratio of 2.35:1 will allow you to use 1/3 measurement but can offer a lot more to be done with the personal preference. This then can elongate the distance to ¼.
