Dieline of Rigid Box: Dimensions, Sizes & Free Template Guide (2026)

A dieline for a rigid box is a flat 2D template that shows exactly where the material gets cut, folded, and wrapped. Unlike a folding carton, a rigid box needs two dielines: one for the chipboard structure and one for the wrap paper. Always measure using inside dimensions (length × width × depth of your product), then add board thickness on every wall. For a standard 2mm greyboard box, add 4mm to each axis for the base and about 1.5mm clearance gap so the lid slides off smoothly.

Why Rigid Box Dielines Trip People Up

Here’s the moment most brands feel it: the sample arrives, the product goes in… and the lid sticks. Or the wrap paper comes up 10mm short and the corner shows raw grey board.

Neither problem is bad luck. Both come from a dieline that skipped the math.

Rigid boxes also called setup boxes are built differently from every other box style. They arrive assembled, not flat. The greyboard is cut, creased, and taped into a shell first. Then a printed wrap paper is glued over the outside and folded inward at the edges. That inward fold is called the turn-in, and it eats material most designers forget to add.

Once you understand that two-layer build, the numbers click into place fast.

The 8 Pain Points This Guide Solves

What a Rigid Box Dieline Actually Shows

Open any print-ready dieline in Adobe Illustrator and you’ll see color-coded lines. Each one tells the die-maker something different.

Pro tip: Keep each element on its own layer cut, crease, bleed, spot UV, foil stamping, and embossing die. Printers love clean layers, and clean layers mean fewer revision rounds.

Inside vs Outside Dimensions: The Rule That Saves Orders

This one line prevents most sizing errors:

Always quote inside dimensions. Always.

Your product sits inside the box, so the inside dimension is what matters. The outside dimension grows on its own once you add material.

The Formula

Outside Length = Inside Length + (board thickness × 2)
Outside Width  = Inside Width  + (board thickness × 2)
Outside Depth  = Inside Depth  + board thickness

Worked Example 2mm Greyboard

That 1.5mm clearance gap is the difference between a lid that glides and a lid that fights you.

Calculating the Wrap Paper

The wrap allowance is where money gets wasted. Use this:

Wrap Width  = Outside Length + (Outside Depth × 2) + (turn-in × 2)
Wrap Height = Outside Width  + (Outside Depth × 2) + (turn-in × 2)

With a standard 15mm turn-in on the box above:

• Wrap Width = 207 + (55 × 2) + 30 = 347mm
• Wrap Height = 107 + (55 × 2) + 30 = 247mm

Add your 3mm bleed to all sides and your print-ready artwork is set.

Greyboard and chipboard are the two names you’ll hear most. Both work beautifully ask your supplier which they stock so your tooling matches.

Rigid Box Styles and Their Dielines

Each style has its own flat layout, so pick the structure before you design.

Rigid Box vs Folding Carton Dieline

A lot of confusion starts here, so let’s clear it up.

File Setup Checklist

Before you send anything to print, run through this:

• Vector format: .AI, .PDF, .EPS, or .DXF
• Color mode set to CMYK, with Pantone spot colors named
• 3mm bleed on every edge
• Text and logos inside the safe zone
• Fonts outlined
• Images at 300 DPI minimum
• Separate layers for spot UV, foil stamping, debossing
• Dieline layer set to overprint, not printing
• 3D mockup approved before tooling

Getting Your Dieline Right the First Time

Order a physical sample box before the full run. A packaging prototype costs a fraction of a reprint, and holding it tells you things a screen never will whether the lid feels satisfying, whether the soft-touch lamination shows fingerprints, whether your satin insert cradles the product.

Teams at ONO Custom Boxes supply the editable dieline with every custom quote, so your designer starts from correct numbers instead of guesses.

2026 Trends Worth Designing Around

• Collapsible rigid boxes ship flat, cut freight costs up to 60%
• Sustainable rigid packaging recycled greyboard, FSC certification, soy inks
• Plastic-free luxury paper wraps replacing PET windows
• AR and 3D dieline previews approve structure before sampling
• QR-coded packaging reserve a clean safe zone on the dieline
• Minimalist kraft luxury uncoated stock with blind embossing

Frequently Asked Questions

What is a dieline for a rigid box?

It’s a flat 2D template showing every cut line, crease line, and bleed area. Rigid boxes need two: one for the chipboard shell and one for the printed wrap paper.

Are rigid box dimensions inside or outside measurements?

Always inside dimensions. Your product fits inside, so quote that. Outside dimensions are calculated by adding board thickness.

How much clearance gap does a lid need?

About 1.5mm on length and width. Less and it sticks. More and it slips off in transit.

What is turn-in allowance?

The extra wrap paper folded to the inside of the box, usually 15mm per side. It hides the raw board edge.

How do I calculate wrap paper size?

Wrap Width = Outside Length + (Depth × 2) + (turn-in × 2). Repeat for height using Outside Width.

What board thickness should I choose?

2mm suits most products. Go 1.2–1.5mm for small jewelry, 2.5–3mm for premium spirits and electronics.

What file format should a dieline be?

A vector file .AI, .PDF, .EPS, or .DXF. A JPG or PNG can’t be used for die-cutting.

Do rigid boxes ship flat?

Standard ones ship assembled, which raises volumetric weight. Choose a collapsible rigid box if freight cost matters.

What’s the minimum order for a custom size?

Custom sizes need new tooling, so MOQs usually start around 100–500 units. Standard sizes often go lower.

Can I design a dieline myself?

Yes. Adobe Illustrator works well, and packaging tools like ArtiosCAD, EngView Package Designer, Kasemake, and Pacdora generate structures automatically.

How do I mark magnet pockets?

Add a labeled circle or rectangle on the board dieline at each magnet position, with depth noted. Most magnets are 10–15mm wide and 1–2mm thick.

What’s the difference between greyboard and chipboard?

They’re near-identical recycled boards. Greyboard is the common term in Europe and Asia; chipboard in North America.
