Free AI Dieline Generator

Generate print-ready packaging dielines in under 60 seconds — with fold lines, cut lines, glue tabs, dimension annotations, and 3mm bleed. Unlike template libraries, Cubit's AI designs your complete artwork on the dieline, so you get a manufacturable box design, not a blank outline.

What Is a Packaging Dieline?

A dieline is the flat, unfolded blueprint of a package. It shows every panel of the box, plus the lines a manufacturer follows to cut, crease, and glue it into its final 3D shape. Every custom box, carton, and sleeve starts life as a dieline — get it wrong and the box won't fold, close, or protect the product.

The Anatomy of a Dieline

Cut lines (solid)

Where the steel die blade cuts through the board — the outer silhouette and any windows or slots

Fold lines (dashed)

Creasing rules where the board folds — panel boundaries, closures, and dust flaps

Glue tabs

Panels where adhesive joins the structure — typically the manufacturer's joint on cartons

Bleed area (3mm)

Artwork extends 3mm past every cut line so trimmed edges never show white board

Safe zone (5mm)

Critical text, logos, and barcodes stay 5mm inside cut lines to survive die-cutting tolerance

Dimension annotations

Length × width × depth callouts the manufacturer verifies before tooling the die

Dieline Templates for 6 Box Types

The AI generates structurally correct dielines — right panel count, tab placement, and fold geometry — for every major packaging format, at your custom dimensions:

How the AI Dieline Generator Works

  1. 1Describe your box: product, box type, rough dimensions, brand style — in plain English.
  2. 2Get your dieline in 60 seconds: a composite image — print-ready dieline (left) + 3D assembled preview (right) at 2K–4K resolution.
  3. 3Refine with canvas tools: annotate changes directly on the dieline; the AI applies them in the next iteration. Unlimited versions, full history.
  4. 4Engineer verification & production: a human packaging engineer finalizes the dieline for manufacturing specs, then Cubit prints your boxes from 100 units.

Dieline Generator FAQ

What is a dieline generator?
A dieline generator creates the flat, unfolded template of a package — all panels, fold lines (dashed), cut lines (solid), glue tabs, and bleed areas — so a manufacturer can die-cut and fold it into a finished box. Traditional generators output a blank parametric template you still have to design on. Cubit's AI generates the structural dieline AND your finished artwork on it in a single step.
What is the best free dieline generator?
Cubit's AI Dieline Generator is the only free tool that produces a designed, print-ready dieline rather than a blank template. Each generation includes correct panel layouts, fold lines, cut lines, glue tabs, 3mm bleed, and dimension annotations — plus a matching 3D mockup — from a plain-English description.
Can AI really generate manufacturable dielines?
Yes. Cubit's AI understands the structural engineering of 6 packaging formats, producing flat production templates with correct panel counts, tab placement, and fold geometry. Before production, a human packaging engineer verifies the dieline against your exact dimensions and material caliper — included in Cubit's manufacturing handoff.
How do I create a dieline for my box?
Open the free Design Studio, describe your product, box type, and rough dimensions in plain English. The AI generates a composite image with the print-ready dieline on the left and a 3D preview on the right in under 60 seconds. Iterate with canvas tools, then hand off to a Cubit packaging engineer who finalizes it for manufacturing.
What file output do I get?
A high-resolution (2K–4K) composite image: print-ready dieline with all panels, fold/cut lines, glue tabs, dimensions, and 3mm bleed, plus a 3D preview of the assembled box. Moving to production, Cubit's design team converts the approved concept into final vector production files matched to the manufacturer's die specifications.
Dieline generator vs dieline template — what's the difference?
A template is a fixed, pre-drawn outline for one standard size that you modify manually. A generator creates the dieline dynamically for your dimensions. Cubit goes further than both: it generates the dieline AND places your complete packaging design on it, so the output is ready for design review — not a blank starting point.
Is it really free?
Yes — generating dielines and 3D previews is free with unlimited iterations, no credit card required. You pay only when you move to manufacturing, where a packaging engineer finalizes your dieline for production. Minimums start at 100 units.
Do I need Illustrator or ArtiosCAD?
No. Cubit's AI dieline generator runs entirely in your browser and requires zero design software or experience — describe your box in plain English and get a structured dieline in under a minute.

Ready to Turn Your Dieline Into Real Boxes?

Cubit isn't only a design tool — it's the factory behind it. Send us your dieline (or one the AI generated) and a packaging engineer verifies it against your material caliper and dimensions, then prints, die-cuts, and ships the finished boxes. Every major die style and size is produced in-house.
