Resolutions[edit]
7680 × 4320 (16:9) (33.1 megapixels)
8192 × 4320 (~17:9) (35.3 megapixels)[1]
8192 × 8192 (1:1) (67.1 megapixels)[2]
Digital cinema[edit]
8K represents the horizontal resolution because there are numerous aspect ratios used in film. So while the horizontal resolution is kept constant, the vertical depends on the aspect ratio that the principal decides to work.
8K UHD[edit]
8K UHD[3] is a resolution of 7680 × 4320 (33.1 megapixels) and is one of the two resolutions of ultra high definition television, the other being 4K UHD. 8K UHD has four times the horizontal and vertical resolution of the 1080p HDTV format, with sixteen times as many pixels overall. Example:
- width: 1920 × 4 = 7680
- height: 1080 × 4 = 4320

8K Fulldome[edit]
8K Fulldome[4] is a resolution of 8192×8192 (67.1 megapixels) and is the resolution of top-end modern projection for hemispherical fulldome theatres often seen in planetariums. 8K Fulldome projects over 4 times the width and over 7 1⁄2 times the height resolution of 1080p HDTV format, with thirty-two times as many pixels overall. Example:
- width: 1920 × 4.266 = 8192
- height: 1080 × 7.58 = 8192
