Cassette J-Card Anatomy & Standard Measurements

Standard Norelco cassette cases use a die-cut or scored card called a J-Card, named for its cross-sectional "J" shape when folded around the cassette shell. Whether you are preserving personal voice-tape letters, recording college audio journals, or releasing physical lo-fi music, precise millimeter dimensions ensure your insert fits snugly without buckling.

Panel Name Width Height Primary Function & Information
Back Flap / Fold-In 19 mm to 20 mm 102 mm Holds catalog number, recording date, barcode/yearbook quotes, and audio recorder gear notes.
Spine (Narrow Edge) 12 mm to 13 mm 102 mm Visible on the shelf; requires rotated title, artist name, and catalog designation.
Front Cover 65 mm 102 mm The iconic visual centerpiece facing through the clear front of the tape case.
Fold-Out Panel (J+1) 63 mm to 65 mm 102 mm Optional extra flap for full tracklists, lyrics, narrative audio-letter chapters, or credits.

Printing & Folding Instructions

Click Export 300 DPI J-Card to download a print-ready PNG with standard 300 dots-per-inch resolution. Print at 100% scale (no scaling / do not fit to page) onto 65 lb or 80 lb light cardstock or matte photo paper. Cut along the solid outer trim lines, then score lightly along the dashed fold lines with a bone folder or blunt stylus before assembling into your cassette case.
