Create a box dieline from your dimensions
Choose a box structure, enter the finished internal size, and generate a downloadable SVG showing cut lines, fold lines, sheet size and estimated board usage.
Choose a box style
Select the structure closest to your packaging project.
Enter internal dimensions
Use finished inside measurements, not the flat sheet size.
For an accurate-size reference, print at 100% scale. Large dielines may exceed standard paper sizes.
What is a box dieline?
A box dieline is the flat technical drawing used to cut, crease and fold packaging into its finished shape. It identifies the panels, flaps, glue areas, cut edges and fold lines that make up the box.
This generator creates an editable SVG planning template from your internal dimensions. It is useful for early sizing, material comparison and artwork planning, but the final production dieline must be confirmed for the selected board and manufacturer.
How to use the box dieline generator
Select the structure
Choose an RSC shipping box, roll-end mailer or straight-tuck folding carton. Each structure uses different flaps and panel arrangements.
Enter the internal size
Add the finished length, width and height of the box. Switch between inches and centimetres at any time; the tool converts your values automatically.
Review and download
Check the preview, estimated flat-sheet dimensions and board area. Download the SVG for planning or print a reference copy at 100% scale.
Which box style should you choose?
The right dieline depends on how the box will be packed, displayed, sealed and shipped. These three structures cover common corrugated and paperboard applications.
Regular slotted box (RSC)
A standard shipping carton with four body panels, a glue tab and top and bottom flaps that meet near the center. It is commonly taped closed and used for master cartons, fulfillment and transport.
Request a shipping-box quote →Roll-end tuck mailer
A one-piece corrugated mailer with a hinged lid, rolled side walls and front tuck. It provides an organized unboxing experience without a separate lid and often requires no glue during packing.
Explore mailer boxes →Straight tuck end carton
A folding carton whose top and bottom tuck flaps close in the same direction. It is widely used for cosmetics, supplements, small electronics and lightweight retail products.
Explore tuck boxes →Understanding cut lines, fold lines and allowances
Cut line
A solid line marking the outer profile and slots where the sheet is cut.
Fold or crease line
A dashed line showing where the board is scored and folded to form panels and flaps.
Glue or joining tab
A narrow extension used to connect the first and last body panels on glued structures.
Board allowance
The tool adds 8% to the calculated sheet area as a planning allowance for trim and production waste. It is not a guaranteed manufacturing yield.
Before placing artwork on a dieline
A technically correct flat layout still needs production-specific checks before print. Use the downloaded SVG as a planning layer, then have the final supplier template confirmed.
Confirm whether the dimensions are internal or external and whether the board thickness has been compensated.
Keep logos, text, barcodes and regulatory copy inside the supplier's safe area.
Extend backgrounds and images beyond cut edges using the printer's required bleed, commonly specified in millimetres or inches.
Check panel orientation. Some panels rotate when the flat sheet is folded into the finished box.
Keep cut, crease and artwork layers separate, clearly named and free from accidental rasterization.
Request a physical or digital proof before approving production, especially for fitted inserts and close-tolerance products.
Why the final dieline may differ
Two boxes with the same internal dimensions can require different tooling. Board caliper, flute direction, score depth, joint design, printing process and packing method all affect the production structure.
- Board grade and thickness
- Flute direction and compression
- Machine and die-cutting tolerances
- Closure and glue requirements
- Product weight and protection
- Printing and finishing processes
Box dieline generator FAQs
Is this a production-ready box dieline?+
No. It is a dimensional planning template. A production dieline needs supplier confirmation because board caliper, crease compensation, tooling, machine tolerances and closure details affect the final structure.
Can I download the dieline as an SVG?+
Yes. Select a box style, enter valid dimensions and choose Download SVG. SVG is a vector format that can be opened in applications such as Adobe Illustrator, Affinity Designer or compatible browser-based editors.
Can I save the dieline as a PDF?+
Use Print / save PDF and select your browser's PDF destination. Choose 100% print scale for an accurate-size reference. If the dieline is larger than the selected paper, use a larger sheet or treat the output as a scaled planning reference.
Does the generator use internal or external dimensions?+
The inputs are intended as finished internal dimensions. External size depends on board thickness and the way the supplier compensates scores and folds.
What does the 8% board allowance mean?+
It is a simple planning allowance added to the calculated flat-sheet area for trim and production waste. Actual sheet utilization depends on nesting, machine format, grain or flute direction, order quantity and supplier workflow.
Can I use this for corrugated boxes and paperboard cartons?+
Yes, for early planning. The RSC and mailer options represent common corrugated structures, while the straight-tuck option represents a folding paperboard carton. Production specifications must still be confirmed for the selected material.
Why did the dimensions change when I switched units?+
The tool converts the values so the physical box size stays the same. For example, 1 inch becomes 2.54 centimetres rather than being reinterpreted as 1 centimetre.
What information should I send for an exact quote?+
Share the box style, internal dimensions, product weight, board preference, print coverage, finishes, order quantity and delivery destination. If available, include product photos or an existing sample.
