Projector Screen Dimensions

The projector screen sizes are divided into formats. Projector ScreenThese include the HDTV (16:9), widescreen (1.85:1), NTSC / video (4:3), slides (1:1) and other AV formats.

Common Aspect Ratios

Aspect ratio refers to the video’s height and width relationship. If you’re looking for the typical home video formats, they are 4:3 (1.33:1) and 16:9 (1.78:1). The 4:3 is called the standard and the 16:9 the widescreen. The 4:3 is used by older TVs and monitors. The 16:9 is employed in HDTV and some home theaters.

For movie watching, a 2.40/2.35 aspect ratio is recommended. However using projector screen sizes with that ratio to watch 16:9 materials will produce black bars on the sides. The same is true if you use that ratio and watch 4:3 content.

Other Projector Screen Aspect Ratios

The 1:1 is best for slide projections. The previously mentioned 4:3 is also known as the NTSC or Academy. Although it’s quickly becoming obsolete, it’s the format to use if you’re going to view older material.

In Europe, the standard for 35mm is 5:3 or 1.66:1 / 1.67. The 1.78:1 ratio was a compromise for the 35mm UK / US 1.85:1 and the 1.66:1. This projector screen size is widely used when viewing sports and TV.

The 2.35:1 is also known as the CinemaScope. Its modern measurement is 2.40:1 but 2.35:1 is used for convenience. While 1.78:1 is used for sports and gaming, the 2.35:1 is utilized more often for movie watching. The reason is that a lot of moves use this format.

Keep in mind that there are other projector screens available. The figures cited above are well known but there are many others.

Choosing the proper projector screen sizes will take time. However it’s something you should study, as the results can and do make a big difference on the material being viewed.
