A CD case is usually 5.59 inches long, 4.92 inches wide, and 0.39 inches deep. Since some CD cases are made to hold more than one CD, the depth of the case can vary. On the other hand, cases rarely change in length or width.
When CDs first came out in 1982, they came in jewel cases that are still used today. When making case covers or inserts, it’s important to know how big the CD cases are. The discs themselves are usually the same size, but CD and DVD cases don’t usually have the same size.
