CD Cover Dimensions & Sizes

The definitive millimeter reference for standard jewel cases, slim cases, and multi-disc formats.

Standard Jewel Case (10mm)

The standard jewel case is the most common CD packaging — the clear plastic case with a hinged lid, typically 10mm thick. The insert that slides into the front is the front inlay, and the booklet that goes behind the tray is the back J-card.

Component	Width	Height	Notes
Front Cover (trim)	120 mm	120 mm	Final cut size including no bleed
Front Cover (with bleed)	121 mm	120 mm	1mm extra on one side for trim safety — this is what CDcovers.cc generates
Back J-Card (total)	150 mm	118 mm	Includes both spine sections
Back Centre Panel	137 mm	118 mm	The main artwork area between the two spines
Spine (each side)	6.5 mm	118 mm	Two spines, one on each edge of the J-card

Slim Case (5mm)

Slim cases — also called slimline or jewel slim cases — are 5mm thick. They use only a front cover. There is no back J-card or spine section in the traditional sense.

Component	Width	Height	Notes
Front Cover (trim)	120 mm	120 mm	Same as standard front
Front Cover (with bleed)	121 mm	120 mm	CDcovers.cc uses this size

Booklet Dimensions

Many commercial CDs include a multi-page booklet that sits in front of the disc, behind the front cover. If you plan to add a booklet:

Safe Zone and Bleed Explained

The bleed is artwork that extends beyond the trim line to ensure no white edges appear after cutting. CDcovers.cc adds 1mm of bleed on the right edge of the front cover (making it 121mm instead of 120mm).

The safe zone is the inner area where important content (text, faces, key design elements) should sit — at least 3mm inside the trim edge on all sides. Content too close to the edge risks being trimmed off.
