What Resolution Should Your Images Be?
cft.vanderbilt.eduimage at 150 LPI, you can use a digital image anywhere from 225 PPI to 300 PPI. (You can, of course have more image data, but it doesn’t give you any better a final result, and just takes up extra disk space and clogs your image processing software upon printing.)

lib2.colostate.eduAn image with a resolution of 72 has 72 dots in a linear inch. The higher the resolution of an image, the better the quality of image you have. The image size is determined by the resolution multiplied by the height and the width of the image. Your height and width will be determined by how you received the image, be it a camera, scan, etc.
