Make this box About the mailer box
Folded shut and measured in 3D: the cavity is 331 × 318 × 16 mm and the product block fits without touching the board. Free to open and change; €2.50 for the PDF, €3.50 for the DXF or SVG.
Why these numbers
A gatefold is 325 mm wide at the hinge, wider than a single LP jacket, so a standard 12.5-inch mailer is too tight. This one is cut to the gatefold plus two pads.
Every size on this page is an example to start from. Products change between models, editions and makers, so measure the one you are packing.
Where the product size comes from
A double LP in a gatefold: from a packaging or retail supplier's listing.

The flat blank
- Folding order: 1) front and back wall up. 2) dust flaps in. 3) side wall up, over the roll bridge, inner wall down. 4) push the tongues at the foot of the inner wall straight into the slots in the base. 5) close the lid and drop the ears into the side pockets.
- Roll bridge = 9.80 mm: 2 layer(s) of 3 mm plus 0.80 mm clearance.
- Front and back wall are inset 6.00 mm at both ends so they fall inside the ear plane. Without that set-back the lid ear runs straight into the front wall.
- The inner wall ends in 2 tongues per side that go straight into slots in the base - no folded-over tab, so the roll has no reverse crease and the sheet never needs turning.
