![]() ![]() While DPI and PPI are used interchangeably, they refer to two different terms: PPI is an input image resolution, and DPI is a resolution of an output device, like a printer. DPI stands for dots per inch DPI is a measure of dot density within an image, in inches.PPCM stands for Pixels Per Centimeter PPCM is a measure of pixel density within an image, in centimeters (cm).PPI stands for Pixels Per Inch PPI is a measure of pixel density within an image, in inches.The PPI calculator assumes, that the horizontal and vertical pixel densities (of the target image) are the same, as the most imaging devices have square pixels. I have an image with 3264 x 2448 pixels and would like to print it as a poster. The calculation results include the image density in PPI (Pixels Per Inch) and PPCM (pixels per centimeter), the image total number of pixels, the image aspect ratio, the image number of pixels per unit of area, the image width and height in numerous units of length, and the image area in many units of area. To calculate the resolution in megapixels, multiply the number of pixels of length and width and divide them by mega (1 million). The PPI calculator computes many attributes of an image using the entered image width and height in pixels, and the image width in any unit of length measurement.This tool changes the width and height of your file. ![]() You can also use the DPI to change the image size when it comes to printing. If you already have these two measurements just insert them into the calculator above and aspect ratio will be calculated as a result. About this page: Pixels Per Inch (PPI) calculator In the drop-down menu, choose the format you want your images to be converted to. How to Use Our Calculator In order to find out the aspect ratio of an image or video, both width and height should be known in advance. ![]()
