Build the pack around the product plus its protection, then check the outside parcel dimensions. A tidy unboxing render helps the brand review; a loaded sample shows whether the product moves, the closure works and fulfilment staff can assemble it reliably.

## Start with a product brief

- Measure the product with its protective wrap or insert in place.
- Separate the usable inside dimensions from the carrier-facing outside dimensions.
- Specify how the pack is sealed, labelled, opened and, if needed, reused for a return.

## Compare relevant structures and products

The catalog currently includes 533 matching templates and named sizes. The groups below are useful starting points; coordinated brand sets are counted separately.

| Group and count | An editable starting point | Download purpose |

| Mailers & shipping: 423 templates and sizes | [E-commerce mailer 250×180×60](https://dielinemaker.com/dielines/mailer-box--mailer-ecom); [Browse this group](https://dielinemaker.com/mockups?category=mailers&use=ecommerce) | dieline |

A supplied product model provides artwork areas. A packaging structure provides the corresponding dieline. Check the individual template page before preparing a production handoff.

## Materials and supplier checks

Compare the corrugated grades permitted by the selected mailer or carton and enter the supplier’s actual caliper. Board thickness in the editor is not a compression, drop or moisture-performance rating.

Have the converter and fulfilment team approve the loaded sample and the transport test appropriate to your distribution route. Verify carrier size rules against the final packed parcel and current service requirements.

## Choose the tool for the job

Match the next task to its workflow before choosing a template or buying a plan.

| Your task | Start here | Why it fits |
| --- | --- | --- |
| Estimate the finished parcel size | [Box size calculator](https://dielinemaker.com/tools/box-size-calculator) | Compare inside and outside sizes with the selected material thickness. |
| Choose a mailer construction | [Dieline generator](https://dielinemaker.com/tools/dieline-generator) | Inspect the flat blank and fold before applying the unboxing artwork. |
| Review assembly and graphics | [Project sharing](https://dielinemaker.com/learn/projects-and-sharing) | Send a saved revision for review, then validate the physical packed sample. |

Check [current plans and export access](https://dielinemaker.com/pricing) before purchasing. Production suitability and supplier approval remain separate from the visual proof.

## Follow the workflow

- [Save projects, organise files and share a revision for review](https://dielinemaker.com/learn/projects-and-sharing)

## Common questions

### Which dimensions should I enter for a shipping box?

Start with the usable inside space required by the product and its protection. Check the resulting outside dimensions separately for storage and shipping. Use the converter’s specification for the production blank.

### Does a folded mockup prove the parcel will survive shipping?

No. The preview helps inspect geometry and artwork. A loaded physical sample and the agreed transit tests are needed to assess protection and closure performance.

## Build from your actual product

Choose a starting template, set its dimensions and review the result with your supplier.
