Free 3D Box Mockup Generator – Any Size

About this shipping box

The regular slotted carton is the box almost everything ships in: one die-cut blank of corrugated board, scored, folded and glued at one tab, with four flaps meeting at the top and bottom. This mockup builds that blank from your three outer dimensions and folds it the way a packer does, so the flap gaps, the glue tab and the square corners are where a real carton has them.

Pick a preset (mailer, shoe box, shipper, cube, moving) or set any size from the sliders. The board switches between brown kraft corrugated, 2–7 mm, and white paperboard, 0.4–1.9 mm; the bend radius follows the thickness. The bottom is not printed, because it never is.

Drag the fold slider to see the flat blank with its print laid out, which is also how a printer proofs it.

Questions

Does the mockup show the box flat as well as folded?

Yes: the fold slider runs from the folded box to the flat blank, printed side up, which is the view a printer proofs.

Can I use my own sizes?

Yes. Each product has sliders for its main dimensions and presets for the common sizes; everything else, such as wall thickness or spine width, follows from them.

What size should my artwork be?

The Artwork panel shows each area's print size in millimetres for the current settings; prepare the file at that size, at 300 dpi if it is for print too.
