Retinal vs Pixel Density Calculator

Not all displays for Mac are well suited to display the user interface in a non-scaled resolution. A pixel density of about 110 pixels per inch (PPI) for non-Retina, and about 220 PPI for Retina is comfortable for most people. Use Retinal to work out the pixel density of any display.

Pixel Density Calculator are used for calculating pixels per inch (PPI) or dots per inch (DPI) of any display based on its dimensions and the pixel count. PPI is a measure of pixel density or resolution of a monitors, smartphones, tablets, smart watches, computer screen, notebooks, television screen or other display device. Pixels per inch indicates how many pixels are in a 1 inch line on a display. Also calculated are screen size, screen width, screen height, aspect ratio and total number of megapixels. Calculation including shape preview. The formula to calculate PPI from diagonal: PPI = √(w² + h²)/d where: d – Diagonal screen size in inches. w – Number of pixels along the horizontal line. h – Number of pixels along the vertical line. Calculate the number of pixels that fit on the diagonal: d = √(w² + h²) where: w - Number of pixels along the horizontal line. h - Number of pixels along the vertical line. Then, calculate the PPI as the ratio between the number of pixels along the diagonal and the diagonal screen size: PPI = d/di where di is the diagonal screen size in inches. Pixels per Inch Quality value 120 PPI - Low 120-160 PPI - Medium 160-213 PPI - Medium High 213-240 PPI - High 240-320 PPI - eXtra High 320-480 PPI - eXtra x2 High 480-640 PPI - eXtra x3 High What is pixel density: Pixels per inch (PPI) are a measurement of the pixel density (resolution) of devices in various contexts: typically computer LCD or OLED displays, image scanners, and digital camera image sensors. The PPI of a computer display is related to the size of the display in inches and the total number of pixels in the horizontal and vertical directions. The PPI and DPI definitions are essentially equivalent. Dots per inch, or DPI, is comparable to pixels per inch. Thanks for your support and do visit nitrio.com for more apps for your iOS devices.
