PackToolbox is a free collection of practical packaging, shipping and freight calculators built to make common logistics calculations faster and easier to understand.
What we build
Our tools focus on real shipping tasks such as dimensional weight, volumetric weight, cubic volume, pallet planning and freight density. Each calculator is designed to show the method behind the answer, including units, formulas and assumptions where relevant.
Who PackToolbox is for
PackToolbox is designed for ecommerce sellers, small businesses, warehouse teams, importers, exporters, freight professionals and anyone who needs quick packaging or shipping calculations.
Our approach
We aim to keep core tools free, fast and usable without an account. We also review formulas and tool behavior as the site expands so that results remain transparent and practical.
What you will find on PackToolbox
PackToolbox combines interactive calculators with practical guides covering parcel carriers, dimensional and volumetric weight, freight, pallets, containers, ecommerce fulfillment, warehouse operations, packaging materials and logistics software. We focus on questions where a formula, cost model, comparison or operational checklist can help readers make a better decision.
How we source and review information
For carrier rules, surcharges, customs information and other changeable details, we prefer first-party documentation from carriers, postal operators, government agencies, standards bodies and software vendors. We distinguish between fixed formulas and rules that can vary by carrier, service, market or contract. Our Editorial Policy & Sources explains the process in more detail.
Editorial independence
PackToolbox may earn revenue from advertising, partnerships or sponsored content as the site grows. Commercial relationships do not change the formulas used by our calculators or guarantee favorable editorial coverage. Sponsored or contributed material must remain relevant to packaging, shipping, ecommerce operations, warehousing, freight or closely related technology.
Contributions and partnerships
We selectively consider expert contributions and commercial partnerships that fit PackToolbox’s subject area and editorial standards. Acceptance is not automatic. Editorial enquiries can be sent to editorial@packtoolbox.com, and partnership enquiries to partnerships@packtoolbox.com. See our Contributor & Partnership Guidelines for the topics and quality requirements we use.
