"For Disketch, you need to use the correct “case” template and then adjust print settings so the insert matches a standard DVD keep case. A standard single‑disc DVD cover insert is roughly 27.5–28 cm wide by 18.4–19 cm high (about 10.8–11 in × 7.25–7.5 in), including the spine.
Make it DVD box size
In Disketch, start a new “DVD and Case” or “DVD Case on Generic Paper” project so it uses a full keep‑case insert layout that spans front, spine, and back.
Before printing, open your printer’s dialog and set “Actual size” or 100% scaling, and disable “Fit to page” or “Shrink to fit” so Disketch’s insert isn’t shrunk by margins.
If the print is still slightly too small or large, use Disketch’s “Label Layout Editor” or print-position/size adjustment to tweak the template dimensions and alignment, then test on plain paper and trim to fit your specific case.
Front and back content
A full DVD insert is one continuous rectangle: left is the back cover, center is the spine, and right is the front cover; Disketch’s DVD‑case template is designed this way, so you place images/text separately in those three regions on a single layout.
Use separate text and image objects for the front panel, back panel (with track list, blurbs, etc.), and vertical spine text; the program lets you add and move multiple overlays on the same cover design.
If you only see a single “front cover” area, switch project type/template to one that explicitly says “DVD and Case” (or similar) so you get both front and back with spine on the same sheet."
