Dot pitch is calculated from the diagonal length in inches and pixels then converted from inches per pixel to millimeters per pixel but normally only expressed in millimeters (mm). FWIW document formats like A4 are described by their print dimensions (millimeters), which is a whole different thing than screen images (pixels) so thats why you.

How to Calculate the diagonal dot pitchĭiagonal dot pitch is the diagonal distance from the center of one pixel to the center of the next. 300 dpi (print) 2480 X 3508 pixels (This is 'A4' as I know it, i.e. So there are 48528 pixels in an area of the screen that is 1 inch wide by one inch high.

Using this same computer screen, PPI 2 will be: Example: Calculate Pixels per Square Inch, PPI 2 For example, changing your image’s values to 75. When the Resize window opens, make sure Percentage is selected at the top so your image’s changes will be measured in percentages. So there are 220.29 pixels in a 1 inch line on the display. To resize the copy, open the image in Microsoft Paint and click the Resize button in the middle-right section of the toolbar at the top of the window.

You want to find the pixel density in one linear inch of display.Ĭalculate the diagonal length in pixels with the Pythagorean Theorem: You have a computer screen that is 1920 pixels wide by 1080 pixels high. Substitute 1 cm for 1 inch to find pixels per square centimeter or PPcm 2. The number of pixels in a square inch represents the resolution or pixel density of an area of one square inch. Multiply PPI × PPI to get pixels per square inch. How to Calculate PPI 2 or Pixels per Square Inch Just substitute cm for inches to find PPcm. For example, 3 x 5 inches becomes 900 x 1500 pixels. You can use the same PPI formula above to calculate pixels per centimeter, PPcm. To convert the size of an image in inches into pixels, just multiply the number of inches in your intended print size by 300 to find the pixel dimensions (assuming your printer is set at the standard 300 dots per inch). If a display does not have square pixels then this calculator does not apply. The PPI will be the same whether it's a horizontal or vertical or diagonal inch because pixels are square and therefore symmetric. Below are the simple steps to do the conversion.
