PACKAGE SIZE GUIDE

Editorial Policy

Package Size Guide is committed to publishing clear, useful and responsible information about package dimensions, box sizes, dimensional weight, shipping requirements and packaging practices.

This Editorial Policy explains how we research, prepare, review, update and correct the information published on PackageSizeGuide.com.

Our Editorial Mission

Our goal is to make shipping dimensions and packaging information easier to understand for individuals, online sellers, small businesses, warehouse teams and anyone preparing parcels for shipment.

Shipping and packaging terminology can sometimes be confusing. Concepts such as dimensional weight, girth, maximum package dimensions, shipping-box measurements and carrier size limits may be explained differently depending on the carrier or service.

Package Size Guide aims to turn these topics into practical, easy-to-follow resources without unnecessarily complicating the information.

What We Publish

Our editorial content focuses primarily on package measurement, shipping dimensions, packaging and related topics.

Topics may include:

Package dimensions and measurement methods
Common shipping box sizes
Length, width and height measurement
Package girth calculations
Dimensional weight and volumetric weight
Shipping carrier package-size requirements
USPS package dimensions
UPS package dimensions
FedEx package dimensions
DHL package dimensions
Amazon FBA packaging requirements
Product packaging guides
E-commerce packaging
Box selection
Packaging efficiency
Shipping preparation
Packaging and shipping calculators

We may also publish educational resources related to logistics, parcel preparation, protective packaging and other closely related subjects when they are useful to our readers.

How We Choose Topics

We select editorial topics based on practical questions that people commonly encounter when measuring, packing or shipping products.

Topics may be identified through common shipping questions, packaging problems, carrier terminology, frequently misunderstood concepts and subjects that require clearer explanations.

We prioritize content that can help a reader complete a practical task, understand a shipping concept or make a more informed packaging decision.

Research and Information Sources

We aim to base factual shipping information on reliable and appropriate sources whenever possible.

Depending on the topic, sources may include:

Official shipping carrier websites
Official carrier service guides
Postal service documentation
Marketplace and fulfillment documentation
Official help centers and support documentation
Published shipping rules and measurement instructions
Packaging standards and technical references
Manufacturer documentation when relevant

When an article discusses a specific carrier, marketplace or shipping service, we aim to prioritize information published by that organization rather than relying exclusively on third-party summaries.

Official Sources Take Priority

Shipping rules may vary between carriers, services, countries, package types and destinations. Requirements can also change over time.

For this reason, official carrier or marketplace information takes priority over the information presented on Package Size Guide whenever there is a difference.

Readers should always confirm important shipping requirements directly with the applicable carrier before sending a package, particularly for oversized, international, restricted, valuable or unusual shipments.

How We Write Our Guides

Our content is written with practical usefulness in mind.

We aim to explain a subject in a logical order so that a reader can understand both the terminology and how the information may apply to a real package.

Where appropriate, our guides may include:

Simple definitions
Step-by-step instructions
Measurement examples
Packaging examples
Common mistakes to avoid
Frequently asked questions
Related shipping terminology
Links to supporting guides
Links to official information sources
Practical calculators and tools

Plain and Understandable Language

Shipping terminology can quickly become technical. Our editorial approach is to use straightforward language wherever possible.

We may use industry terminology when it is necessary, but we aim to explain important terms rather than assuming every reader already understands them.

Our goal is to make the content useful for both experienced online sellers and people preparing a shipment for the first time.

Accuracy Standards

We make reasonable efforts to provide accurate and useful information at the time an article is prepared or updated.

Before publishing information involving package limits, dimensions, formulas or carrier terminology, we aim to review the relevant details and present them in the correct context.

However, no informational website can guarantee that every shipping rule remains unchanged. Carriers may revise rates, dimensional-weight divisors, package limits, service conditions, surcharges or other requirements.

Readers should therefore treat our content as educational information and verify time-sensitive shipping requirements with the relevant service provider.

Dimensional Weight Information

Dimensional weight is an important topic on Package Size Guide because shipping costs may depend on both package weight and the amount of space occupied by a parcel.

Dimensional-weight formulas, divisors and billing methods can differ depending on the carrier, shipping service, contract, destination and other factors.

Examples and calculators provided on our website are intended to help readers understand the concept and estimate results. They should not be considered a guaranteed carrier quote.

Always verify the applicable divisor, rounding method and billing rules with the carrier being used.

Calculator Standards

Package Size Guide may provide calculators designed to simplify common packaging and shipping calculations.

These tools may include:

Box Size Calculator
Dimensional Weight Calculator
Package measurement tools
Other shipping-related calculators

Calculator results are estimates based on the values entered by the user and the formulas used by the tool.

A calculated result does not guarantee shipping acceptance, eligibility, final shipping cost or compliance with a specific carrier's current requirements.

Users should confirm important shipping calculations with the applicable carrier before purchasing postage or sending a shipment.

Content Review Process

Before publication, content may be reviewed for clarity, relevance, structure and factual consistency.

The review process may include checking:

Whether the article answers the stated question
Whether important terminology is explained
Whether measurements and calculations are understandable
Whether examples are logically consistent
Whether links point to relevant resources
Whether carrier-specific information is properly qualified
Whether the content contains unnecessary repetition
Whether statements may need additional context or clarification

Content Updates

Shipping information is not static. Package limits, service requirements, pricing methods and marketplace standards can change.

We may update existing articles when we identify changes that materially affect the usefulness or accuracy of the information.

Updates may include:

Revising outdated shipping information
Clarifying confusing explanations
Updating package-size requirements
Updating carrier terminology
Adding new examples
Improving calculators
Adding links to related resources
Removing information that is no longer relevant

Corrections Policy

We take factual corrections seriously.

If we discover a meaningful factual error, misleading explanation, incorrect calculation or outdated statement, we may revise the affected content.

Readers who believe they have found an error are encouraged to contact us and provide the page URL along with an explanation of the issue.

Additional information about our correction process is available on our Corrections Policy page.

Editorial Independence

Package Size Guide aims to maintain editorial independence in the preparation of its informational content.

References to shipping companies, marketplaces, packaging brands or other organizations do not automatically constitute an endorsement.

Companies mentioned in our guides do not control our editorial conclusions merely because their services or products are discussed.

Advertising and Commercial Relationships

Package Size Guide may display advertising, sponsored placements or other commercial content in order to support the operation of the website.

Advertising relationships should not determine the factual conclusions of our independent informational guides.

When content is sponsored or materially influenced by a commercial relationship, we aim to provide appropriate disclosure where required.

Affiliate Links

Some pages may contain affiliate links. If a visitor purchases a product or service through an affiliate link, Package Size Guide may receive a commission without necessarily increasing the price paid by the visitor.

The presence of an affiliate relationship does not guarantee that a product, service or provider is suitable for every user.

Readers should evaluate products and services according to their own needs before making a purchasing decision.

AI-Assisted Editorial Tools

Package Size Guide may use software, automation or artificial intelligence tools to assist with certain parts of the editorial workflow, such as research organization, content structuring, proofreading, formatting or identifying topics that may require additional explanation.

The use of automated tools does not change our editorial goal: information published on the website should be useful, understandable and relevant to the reader.

Automated output should not be treated as an authoritative source for carrier policies. Carrier-specific facts and requirements should be checked against appropriate sources whenever necessary.

No Paid Placement Disguised as Independent Advice

We believe readers should be able to distinguish editorial information from promotional material.

Sponsored or promotional relationships should not be intentionally presented as independent editorial recommendations without appropriate disclosure.

Brand Names and Trademarks

Package Size Guide discusses companies and services such as USPS, UPS, FedEx, DHL and Amazon when relevant to shipping and packaging topics.

Company names, logos, product names, service names and trademarks belong to their respective owners.

Their inclusion on Package Size Guide is generally for identification, comparison, reference and educational purposes.

We Are an Independent Information Website

PackageSizeGuide.com is an independent informational resource.

Unless specifically stated otherwise, we are not affiliated with, operated by, sponsored by or officially endorsed by USPS, UPS, FedEx, DHL, Amazon or other companies discussed on the website.

We cannot approve shipments, provide official carrier exceptions, guarantee package acceptance or determine the final price charged by a shipping provider.

User Responsibility

Information published on Package Size Guide is intended for general informational and educational purposes.

Users remain responsible for checking the dimensions, weight, packaging, contents, destination and applicable shipping requirements of their own shipments.

Before sending a parcel, users should confirm the latest rules directly with the chosen carrier, postal service, fulfillment provider or marketplace.

Feedback From Readers

Reader feedback can help us identify unclear explanations, outdated information and topics that deserve additional coverage.

If you find an error or believe a guide could be improved, you may contact us through our Contact page.

When reporting an issue, including the URL of the relevant page and a brief explanation helps us review the matter more efficiently.
