Megapixels to Image Resolution Calculator

Nothing complicated, I just keep needing to figure out x, y resolutions in pixels for an image given in megapixels so I threw together a quick tool.

Takes the resolution of the image in megapixels (e.g. 24 is 24 megapixels, 0.6 is 600,000 pixels), and the aspect ratio either in “n:m” notation (e.g. 3:2) or as a decimal number (e.g. 1.5). Returns the x and y sizes in pixels for that image rounded to a pixel.

Glad you found it useful.

Thanks for the calculator. The calculation using the “n:m” notation when “m” is 10 or larger doesn’t work. “m” gets truncated to one character.
16 Mpixel 16:10 or 16:100 calculates to 16000 x 1000 which is the 16:1 ratio

Hi Tobias,

Thank’s for finding that bug. It should be fixed now.
