So when you want to put a digital image on an physical object such as print, canvas, metal etc then those pixels get an actual dimension. Since a digital image is not physical each pixel does not have a set size. This is where it gets a little complicated. You get that number by multiplying 3000 x 2000. If you are into the mathematics, the said picture would be 6 million pixels, or 6 megapixels. That means there are 3000 rows of pixels and there are 2000 rows (width and height). Let’s say you have a 3000×2000 pixel image. Resolution also refers to the pictures size. Resolution refers to the number of pixels in an image. Now that you know what pixels are, let’s move on to resolution.
