PHOTO RESOLUTION CALCULATOR HOW TO
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. 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
So there are 220.29 pixels in a 1 inch line on the display. Dont Make Me Math Give Me a CALCULATOR Image Proportion Resize and Resolution Calculator. You want to find the pixel density in one linear inch of display.Ĭalculate the diagonal length in pixels with the Pythagorean Theorem: What Size Can I Change My Image To - Image Resize Calculator. 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. You can use the same PPI formula above to calculate pixels per centimeter, PPcm.
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. The number of pixels per inch or PPI tells you how many pixels are in a 1 inch line on a display screen.
