We can also express these values in camera megapixels by multiplying them together to come up with 283,500 pixels or 0.28 megapixels, which we can usually see in our camera settings. By multiplying 180 PPI by the print dimensions of a 2R photo paper, which is 2.5" x 3.5", we get our required image dimensions in pixels of 450 pixels x 630 pixels. Let's say we want to print our pictures on sheets of 2R wallet-sized photo paper.įor this print, we can go for the 180 PPI pixel density. If you like taking pictures and plan to have them printed right away and you need to save some storage space, you can use the equations above to know the minimum camera resolution you need for your desired print size. Image height in pixels = picture height * pixel density
Image width in pixels = picture width * pixel density On the other hand, to calculate the required image file dimensions (in pixels) for a standard photo size or a specific print size at a desired pixel density, we just have to multiply the print width and print height by the pixel density, separately, as shown in the equations below: Print height = 4800 pixels / 300 pixels per inchįrom the computation above, we can now say that we can print the said image file up to a print size of 12" x 18" without compromising the image quality. Print height = image height in pixels / pixel density
