Rigid setup boxes
12 × 9 × 3 in two-piece rigid box dieline
This dieline was generated at exactly 12 × 9 × 3 in (304.8 × 76.2 × 228.6 mm) by the same structural engine that produces our factory print files — every panel, flap and glue zone computed for this size, not stretched from a template.

What fits in 12 × 9 × 3 in
The everyday e-commerce size: apparel, a small electronics bundle, a two-to-three item subscription box.
Shipping note: carriers bill the greater of actual and dimensional weight. At 12 × 9 × 3 in the dimensional weight is about 2.3 lb (US domestic divisor 139), so if your product is lighter than that, the box size — not the product — is setting your freight cost.

What are the actual dimensions of a 12 × 9 × 3 in two-piece rigid box?
12 × 9 × 3 in is the FINISHED internal size — the space your product actually occupies. Flat, before folding, the die measures 919 × 405 mm (36.19" × 15.94"), which is the sheet size a printer needs to quote the job. That works out to 324 cubic inches (5.31 litres) of internal capacity.
What is the dimensional weight of a 12 × 9 × 3 in box?
About 2.3 lb at the US domestic divisor of 139. Carriers bill whichever is greater — actual weight or dimensional weight — so for anything light and bulky this is the number that sets your shipping cost. Dropping a dimension by an inch is often cheaper than negotiating a rate.
Can I get a 12 × 9 × 3 in two-piece rigid box custom printed?
Yes. Design it free on this exact dieline — the artwork lands on the real structure, not a mockup — and runs start at 100 units. You can also export the print-ready file and take it to any printer.
