How many pixels in a 12 megapixels image? How does that compare to difference aspect ratio? What is the resolution of Digital Cinema with 21:9 aspect ratio? How many megapixels by giving X width and Y height by image? How about the aspect ratio? The answer is here! This is a megapixel-resolution calculator, a tool to calculate and convert the graphical resolution base on 4 different aspect ratios 4:3 (SD), 16:9 (HD/fHD/4K), 21:9 (cinema) and 1:1. This tool also calculates and convert graphical resolution to megapixels. The output will include 4 different aspect ratios 4:3 (SD), 16:9 (HD/fHD/4K), 21:9 (cinema) and 1:1 if the ratio match one of these. Preview box will give you an impression for resolution input. 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 is usually 4:3 (SD). However newer digital cameras/camcorders aspect ratio is 16:9 (HD/fHD/4K). Video cameras such as camcorders can be either 4:3 (SD) or 16:9 (HD/fHD/4K). Some camcorders (video and digital) can do both 4:3 (SD) and 16:9 (HD/fHD/4K).
