4K Recording Area is 22.2mm x 12.6mm
3K Recording Area is 16.65mm x 9.36mm
2K Recording Area is 11.1mm x 6.24mm
In Imperial (meaning American), that translates as follows :
RED 4k .874 x.496
Red 3k .650 x .369
Red 2k .437 x .246
Note that RED in 4K is not a Super 35 sensor width if you are calculating angles of view of fields of view, you should note that RED in 4k is closer to 35mm Academy width Super 35 is either .945 or .925...depending on where you get your cameras....and there is a long story behind the difference ...
Hope this helps
