The total pixel dimensions of an image will tell you how many total pixels (dots) the image is made up of. For example, let’s say we have a digital image that is 1200x1800 pixels (dots). That means our digital image is 1200 dots high by 1800 dots wide. So, unless you resample (which means you artificially alter the pixel dimensions in a photo editing program) or crop the image, your image will always be 1200x1800 pixels. People regularly discuss digital images in terms of DPI, which stands for Dots Per Inch. The DPI of a digital image is calculated by dividing the total number of dots wide by the total number of inches wide OR by calculating the total number of dots high by the total number of inches high. Let’s say we have a digital image that is 12 00x1800 pixels (dots) and 4圆 inches in size.
