The math is straightforward obviously, you just need to know the resolution and screen size of your device to calculate ppi.Ī tables for common resolution to pixels per inch (ppi) conversion results. To calculate the resolution in megapixels, multiply the number of pixels of length and width and divide them by mega (1 million). PPI = Diagonal In Pixels/Diagonal In InchesĪlso, you need the below formula to calculate diagonal in pixels: Manually, Calculating ppi manually is using the following formula: Online method is better than manually, because it is fast and more accurate, especially if you have no time to do the conversion manually. Second, enter the screen diagonal size in inchesįinally, click on convert button How is ppi calculated?Ĭalculating ppi from resolution is simple and easy, and you can do that not only online using the resolution to ppi converter we provide, but also manually using the resolution to ppi conversion formula. PPI is a measure of pixel density or resolution of a computer screen, television screen or other display device. It will calculate PPI when inches are entered and calculate both PPI and PPcm when centimeters are entered. How To Use Resolution To PPI Converterįollow this three steps to use the above converter:įirst, enter the screen resolution value in pixel The PPI Calculator finds pixels per inch (PPI) and pixels per centimeter (PPcm). When you zoom to 100 in programs like Photoshop or Illustrator youre not actually seeing true print size, but if you know your monitors DPI (dots per inch), also known as PPI (pixels per inch), you can work around this. However, screen resolution or display resolution usually displayed as width x height. In addition, the resolution is the result of multiplying the number of pixels along the horizontal by the number of pixels along the vertical of the screen or display. Screen resolution or display resolution is the number of pixels that a screen can display. Resolution to ppi converter help you in calculating ppi from resolution accurately. Moreover, pixels per inch or ppi value defines the number of pixels per unit of length (pixel density), for a surface intended to be typically displayed on a terminal: screen, for example computer, tablet, smartphone or television. PPI is a unit of measurement for the resolution of a digital image. This is the chart for the perfect viewing distance from a screen of an image with a minimum resolution to see it clearly.Screen Resolution in pixel (Width X Height): Horizontal Dots per Inch = \(\dfrac = 4.18 MP\) DPI Viewing Distance chart Divide the horizontal pixels in your image by the width of the image and vertical pixels by the height of the image. We will calculate horizontal and vertical DPI separately. Suppose we have an image with \(1200 \times 1080\) resolution, 8 inches wide and 5 inches long. Measure the height and width by using a ruler and note down. Next, you will need the height and width of your image or screen. Note down the resolution which you would have found in pixels because this resolution will be used to complete our calculation. If you have selected an image, go to its properties and check its resolution, or if you are about to calculate DPI for your computer screen, find out the resolution of your screen in the display options or graphic properties. Or you can also calculate the dots per inch for a computer or laptop screen. Select an image on your computer for which you need to calculate the DPI. The dot per inch can be lower or higher than the pixel per inch of the image depending upon the characteristics of the printer. Since DPI means the amount of ink dots per inch in a printer, and that is regardless of the image resolution, which is to be printed. When you are speaking of an ink printer, the defaults are usually DPI instead of PPI. In modern digital displays, the value is directly related to PPI, as each pixel represents one dot in the image, but not always a 1:1 correlation. DPI would quantify the total points with an average length of 1 inch as the name implies. Multiply the width and height of a resolution, i.e., 2560 by 14 by 1080. It is like PPI, each calculating the grainy dimension of an image. What is DPI?ĭPI stands for dots per inch. Choosing from this advanced option will automatically update the resulting pan with the resolution and size of the screen. There are multiple devices available to choose from when you select a specific operating system. The advanced options for the operating system include Windows, iOS, Android, BlackBerry, OS X, Chrome, and SDI. Using the overwatch DPI calculator, you can use the advanced options to choose an operating system as well as several make and models from various companies. The diagonal size can be entered in millimeters, centimeters, and inches. The DPI calculator also referred to as the mouse DPI calculator, is used to calculate the dots in one inch of the display.
