Printing CD album art inserts can be a headache if you're doing through trial and error, as you're bound to end up with an insert that is either too large or too small to fit the CD case. Once you know the proper dimensions, however, you can print perfectly-sized inserts whenever you need them. This process works whether you have the most bare-bones graphics software or the most elaborate.

Open the image that you want to turn into a CD case insert.
Click "Image" at the top of the screen and select "Image Size" or "Attributes."
Click "Inches" in the "Units" area or select "Inches" from the "Units" drop down box. Click "Constrain Proportions" or "Keep Current Proportions" if there is a check mark next to it to turn it off.
Type "4.75" in the "Width" box and type "4.724" in the "Height" box. Click "OK."
Click "File" and select "Print." Carefully cut on along the image border. The insert should fit perfectly in slim and regular-sized CD cases.
