Understanding Resolution and Print Size

Resolution is the number of individual pixels squeezed into each inch of your digital photo. The basic rule's simple. The higher your photo's resolution, or dpi (dots per inch), the sharper, clearer, and more detailed the printout will be. If the resolution is too low, your print appears blurry or speckled. Low-resolution photos are responsible for more wasted printer ink and crumpled photo paper than any other printing snafu, so it pays to do some simple calculations before you print, to make sure your digital photo has enough resolution for the print size you want.
