The term resolution can be used to describe the actual size of pixels. If the image is printed so that it is 25 centimeters wide, each pixel measures 0,0083 centimeters. Suppose I just print that same image on an A4 size sheet with my printer at home.With 3000 pixels to divide over that distance, each pixel is 3.43 centimeter wide. The Stamford Bridge field is 103 meters or 73.3 yards long.Maybe they become very small or maybe they become big enough to fill the football field of Stamford Bridge, the home of Chelsea Football Club. When you print the image or display it on some physical device, then those pixels do get actual dimensions. So, how large is a pixel? Since a digital image is not physical, the pixels in it don’t really have a size. That is typically the case in the printing industry. The term resolution can however also be used to describe the actual or assumed size of pixels. The above definition is pretty straightforward. Resolution as the definition of the absolute size of an image The habit of using the term resolution to refer to the number of pixels in an image is typical for the photography market. Those 6 million pixels equal a resolution of 6 megapixels. Sometimes users are only interested in the total number of pixels. That means the above image of the bird has a resolution of 3000 x 2000 pixels. Resolution describes the image size as the number of pixels it contains, typically as ‘width x height‘. In the above image, each row contains 3000 pixels and there are 2000 rows. Resolution as the definition of the number of pixels
