This is a resolution calculator, a tool to calculate and convert graphical resolution to megapixels. The output will include 4 difference aspect ratios 4:3 (SD), 16:9 (HD/fHD), 21:9 (cinema) and 1:1 if the ration match one of these.21:9, 16:9 and 4:3 is the ratio of x:y or width:height of the image sensor or output image/video format.Older digital cameras/camcorders aspect ratio are usual 4:3 (SD). However newer digital cameras/camcorders aspect ratio are 16:9 (HD/fHD). Video cameras such as camcorders can be either 4:3 (SD) or 16:9 (HD/fHD). Some camcorders (video and digital) can do both 4:3 (SD) and 16:9 (HD/fHD).How many megapixels by giving X width and Y height by image? How about the aspect ratio? The answer is here!
