Terms of Use
Conditions for using PackCalcs calculators, understanding estimates, and checking real shipping and packaging requirements.
Using the tools
PackCalcs provides free calculation and illustration tools for shipping, packaging, and logistics planning. You are responsible for entering accurate measurements and selecting assumptions that match the task. Review units, orientation, quantity, and whether dimensions are internal or external.
You may use and save the results for your own planning and business workflows. Use the website lawfully and do not interfere with its operation or misrepresent a generated result as an independently certified plan.
Outputs and professional decisions
Results depend on the data and models shown. Packing tools use bounded heuristics; a feasible arrangement is not proof of a mathematical optimum, safe stacking, or compliant load restraint. A dieline is a prototype and requires production review.
Confirm carrier tariffs, equipment specifications, protective performance, route restrictions, taxes, and other applicable requirements with the responsible provider or qualified professional. The calculators do not issue bookings, quotations, certifications, or manufacturing approval.
Availability and changes
Tools and explanations may be updated to improve accuracy or usability. Preserve the inputs and assumptions used for any result you need to reproduce. The site does not promise uninterrupted availability or a particular commercial outcome.
A tool that has already loaded calculates locally, but navigating to a new page or obtaining assets may require a network connection. Browser features such as downloading, clipboard access, and printing can depend on your device settings.
Accuracy and responsibility
The formulas and examples are intended to be useful and transparent, but errors or mismatches with a particular use case are possible. Check consequential outputs before committing money, materials, or cargo. Report a reproducible error through the configured contact route when available.
These terms do not exclude rights or remedies that cannot lawfully be excluded. The operator must confirm its legal identity, applicable terms, and any jurisdiction-specific requirements before public launch.
Third-party references
References to carriers, pallet organizations, and packaging standards provide context. They do not create an affiliation, endorsement, or guarantee. The linked provider's current specification or contract controls its own service.
