CD Size report
A record is a generalization of the medium of music dissemination. The material form of documents can be divided into early steel records, bakelite 78 RPM records, vinyl records, today's CDs, etc. A CD is an optical disc used to store digital data, originally developed to store digital music. In 1982, CDs remained the standard storage format for commercial recordings nowadays.
With the rapid development of the computer Internet and the popularization of digital records, more people tend to download their favorite programs from the Internet. Fortunately, you can still find CDs in different designs and standard sizes in traditional video stores.
CD technology was later used to store data, known as CD-ROM. Recordable optical discs followed, including the write-once CD-R and the rewritable CD-RW, and became one of the most widely used storage media in the personal computer industry until the early 2000s. The CD and its derivative formats were extremely successful.
CD Size Guide

Whether buying or making a CD, you should be aware of the CD size requirements to ensure that it will play properly in a CD player.

CD Cover Size
The finished dimensions for the outside of printed CD covers are 4.7" x 4.7" square. Many printed designs include bleed. The "bleed area" is an extra 1/8" of space for design elements or backgrounds to extend beyond the finished size of your piece.
