General Information Disclaimer

Package Size Guide publishes general information related to packaging, shipping, dimensional weight, carrier requirements, box dimensions and other related subjects.

We make reasonable efforts to provide useful and accurate information, but we do not guarantee that every article, measurement, formula, calculation, carrier rule or other piece of information will always be complete, accurate or current.

Visitors should independently verify information that may affect an important shipment, purchase or business decision.

Package Size Guide Is an Independent Website

PackageSizeGuide.com is an independent informational website.

Unless explicitly stated otherwise, we are not affiliated with, operated by, sponsored by or officially endorsed by USPS, UPS, FedEx, DHL, Amazon or any other shipping carrier, postal operator, marketplace, logistics provider or fulfillment company discussed on this website.

References to third-party companies and services are provided for informational and identification purposes.

We Are Not a Shipping Carrier

Package Size Guide does not transport, accept, process or deliver packages.

We cannot:

Track your shipment
Locate a missing package
Change a shipping address
Approve package dimensions
Guarantee acceptance of a shipment
Provide an official shipping quote
Schedule a carrier pickup
Issue shipping refunds
File claims with a carrier
Resolve delivery disputes
Modify marketplace or seller accounts

Questions about an actual shipment should be directed to the carrier, marketplace or fulfillment provider handling that shipment.

Carrier Information Can Change

Shipping carriers may change their services, package-size restrictions, dimensional-weight rules, surcharges, pricing methods and other requirements at any time.

Information that was correct when an article was published may later become outdated because of changes made by a carrier or marketplace.

Always verify important shipping requirements using the current official documentation provided by the applicable carrier.

Package Dimensions Disclaimer

Package and box dimensions published on Package Size Guide are provided as general references unless otherwise stated.

Actual dimensions can vary by box manufacturer, packaging supplier, product version, measurement method or packaging style.

Before purchasing or using packaging, users should independently confirm the exact internal and external dimensions required for their product or shipment.

Internal and External Box Measurements

Packaging dimensions may sometimes refer to internal dimensions and sometimes to external dimensions.

This difference can affect whether a product fits inside a box and how the package is measured by a shipping carrier.

Visitors should confirm which measurement standard applies before relying on a stated box dimension.

Dimensional Weight Disclaimer

Package Size Guide publishes information about dimensional weight, also sometimes called DIM weight or volumetric weight.

Dimensional-weight formulas and divisors can differ depending on the carrier, shipping service, destination, account type, customer agreement and other factors.

A dimensional-weight calculation shown on Package Size Guide should therefore be treated as an educational estimate unless it has been independently verified for your specific carrier and shipment.

Dimensional Weight Calculator Disclaimer

Our Dimensional Weight Calculator is designed to help users understand and estimate dimensional weight.

Results depend on the dimensions, units, divisor and other values entered into the calculator.

Calculator results are not official carrier quotes and do not guarantee the final billable weight or shipping price charged by a carrier.

Users should verify the applicable dimensional-weight rules directly with their carrier before purchasing postage or making shipping decisions.

Box Size Calculator Disclaimer

Our Box Size Calculator is intended to provide a general estimate of a potentially suitable box size based on the measurements entered by the user.

The calculator does not account for every possible packaging requirement, product shape, material thickness, cushioning method or carrier restriction.

Users remain responsible for determining whether a recommended box provides sufficient protection and complies with applicable shipping requirements.

Calculator Results Are Estimates

All calculators and tools available on Package Size Guide are provided for informational and planning purposes.

Calculator results should not be interpreted as:

A guaranteed shipping charge
An official carrier calculation
A guarantee of package acceptance
A guarantee of regulatory compliance
A guarantee that a particular box is suitable for a product
Professional logistics advice

Where the accuracy of a calculation is important, verify the result independently.

Shipping Cost Disclaimer

Package Size Guide does not guarantee shipping prices.

Actual shipping costs can depend on many factors, including:

Actual package weight
Dimensional weight
Package dimensions
Origin and destination
Shipping zone
Selected service level

Account-specific rates
