Perimeter = (Width unit of length + Height unit of length)×2Īrea = Width unit of length × Height unit of length Height unit of length = Width unit of length÷(Width px÷Height px)

How to find the height of an image in units of length?.The number of pixels in an image is equal to the product of width, in pixels by height, in pixels: How to find the number of pixels in an image?.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. 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. 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.About this page: Pixels Per Inch (PPI) calculator.
