PACKAGE SIZE GUIDE
Corrections PolicyAccuracy is important to Package Size Guide. We aim to provide clear, useful and reliable information about package dimensions, box sizes, dimensional weight, carrier requirements and shipping-related calculations.
If information published on PackageSizeGuide.com is found to be incorrect, outdated, incomplete or potentially misleading, we review the issue and make appropriate corrections when necessary.
Our Commitment to Accuracy
Package Size Guide publishes educational resources designed to help readers better understand shipping dimensions, packaging measurements, dimensional weight and common carrier rules.
Because shipping requirements can change over time, maintaining accurate information is an ongoing process. Carriers may update package-size limits, dimensional-weight formulas, service conditions, surcharges, terminology or other requirements.
We therefore review reported errors and may update existing content whenever a meaningful correction or clarification is needed.
What Types of Errors Can Be Reported?
Readers are encouraged to contact us if they believe any information on Package Size Guide may be incorrect or outdated.
Examples include:
- Incorrect package dimensions
- Outdated carrier size limits
- Incorrect weight limits
- Dimensional weight calculation errors
- Incorrect formulas or divisors
- Misleading shipping explanations
- Incorrect measurement instructions
- Outdated marketplace requirements
- Broken or incorrect links
- Incorrect references to carrier services
- Contradictory information within an article
- Formatting errors that materially change the meaning of information
We also welcome reports about explanations that may be technically correct but unclear enough to potentially confuse readers.
How to Report an Error
If you believe you have found an error, please contact us through our Contact page.
To help us review the issue efficiently, please include as much of the following information as possible:
- The URL of the page containing the possible error
- The specific sentence, number, formula or section in question
- A brief explanation of why you believe the information is incorrect
- The correct information, if known
- A link to an official carrier, marketplace or authoritative source when available
Detailed reports help us identify and review potential problems more accurately.
How We Review Correction Requests
Receiving a correction request does not automatically mean that published information is incorrect. Each meaningful report may be reviewed before a change is made.
Depending on the subject, our review may include:
- Rechecking the original source used for the article
- Reviewing current official carrier documentation
- Checking marketplace or fulfillment documentation
- Recalculating mathematical examples
- Testing a calculator or formula
- Comparing multiple sections of the article for consistency
- Reviewing whether the wording may create an inaccurate impression
For carrier-specific information, current official information from the applicable carrier generally takes priority over third-party interpretations.
Substantial Factual Corrections
A substantial correction involves information that could materially affect a reader's understanding or decision.
Examples may include:
- An incorrect maximum package dimension
- An incorrect weight limit
- An outdated dimensional-weight divisor
- An incorrect mathematical formula
- An inaccurate explanation of a carrier requirement
- A significant calculation error
- An incorrect shipping-service restriction
When a substantial factual error is confirmed, we aim to correct the affected information and review nearby sections to determine whether related statements also require updating.
Minor Corrections
Not every change requires a formal correction notice.
Minor edits that do not change the meaning of an article may be made without an individual correction notice.
These may include:
- Spelling corrections
- Grammar improvements
- Punctuation changes
- Formatting adjustments
- Minor readability improvements
- Fixing broken internal links
- Improving headings without changing the underlying information
Clarifications
Sometimes published information is not factually wrong but may be too broad, ambiguous or difficult to interpret.
In these situations, we may revise the wording to provide additional context or make the intended meaning clearer.
A clarification may include explaining that a package limit applies only to a particular shipping service, destination, account type or carrier program.
Corrections to Package Dimensions
Package dimensions are a central topic on Package Size Guide, so measurement-related errors receive particular attention.
If an article contains an incorrect dimension, we may review:
- The stated length, width and height
- The order in which dimensions are presented
- Whether measurements refer to internal or external dimensions
- Whether units have been converted correctly
- Whether the dimensions apply to a specific carrier or packaging product
Readers should remember that box dimensions can vary between manufacturers even when products are described using similar size names.
Corrections to Dimensional Weight Information
Dimensional weight calculations depend on package measurements, mathematical formulas and sometimes carrier-specific divisors.
If a dimensional-weight example or calculator result appears incorrect, we may review:
- Package length, width and height values
- The multiplication used to calculate package volume
- The dimensional-weight divisor
- Unit conversions
- Rounding methods
- Carrier-specific requirements
Dimensional-weight rules can vary by carrier, shipping service, destination and customer agreement. A formula shown for one shipping scenario may not necessarily apply to another.
Corrections to Our Calculators
Package Size Guide provides tools such as our Box Size Calculator and Dimensional Weight Calculator.
If a technical problem, incorrect formula or unexpected result is reported, we may test the calculator using multiple sample values before making a change.
Calculator results are informational estimates and should not be interpreted as guaranteed carrier quotes or shipment approvals.
Outdated Carrier Information
Shipping companies periodically change their services and requirements.
Information involving USPS, UPS, FedEx, DHL, Amazon FBA or another shipping or fulfillment service may therefore become outdated even if it was accurate when originally published.
When we identify a meaningful change, we may update the article to reflect more current information.
Readers should always verify time-sensitive requirements directly with the relevant carrier before shipping.
Updates Are Not Always Corrections
A content update does not necessarily mean that the previous version contained an error.
We may update articles because:
- A carrier has introduced a new service
- A shipping requirement has changed
- New information has become available
- We have added a calculator or related guide
- Examples can be improved
- Additional context would make the article more useful
- Our website structure or internal links have changed
These editorial updates are part of our effort to keep Package Size Guide useful and understandable.
How Quickly Are Corrections Made?
We aim to review meaningful factual errors as reasonably as possible after they are identified.
The amount of review required can vary depending on the issue. A simple numerical mistake may be easier to verify than a complex carrier requirement that varies by shipping service or destination.
Accuracy takes priority over making an unsupported change simply because a correction has been requested.
Correction Notes and Transparency
Minor spelling, grammar, formatting and readability improvements may be made without a correction notice.
When a significant factual error is corrected, we may add or revise information within the article to ensure that readers receive the correct context.
Where appropriate, a page's updated date may also reflect a meaningful revision.
Our priority is to ensure that the current version of the page presents information as accurately and clearly as reasonably possible.
Disagreements About Information
Not every correction request represents a factual error.
Shipping rules can vary by country, service type, account, package category, destination and carrier contract. Different sources may also describe similar rules using different terminology.
If we determine that existing content remains accurate, we may leave it unchanged. However, we may still improve the explanation if additional context could prevent misunderstanding.
Official Sources Take Priority
Package Size Guide is an independent informational website and is not an official source for any shipping company or marketplace.
If information on our website conflicts with current official documentation from USPS, UPS, FedEx, DHL, Amazon or another applicable provider, readers should follow the official provider information.
Package limits and shipping requirements should always be confirmed before preparing an important, oversized, restricted or unusual shipment.
Editorial Independence and Correction Requests
Correction requests are evaluated based on the accuracy of the information rather than whether a person, company or organization prefers different wording.
We do not generally remove accurate information simply because it is inconvenient, unfavorable or commercially undesirable to a third party.
However, legitimate factual errors, misleading statements and outdated information are appropriate subjects for review.
Reader Feedback Helps Improve Our Guides
Readers often encounter shipping rules and packaging situations in real-world circumstances. Feedback can therefore help us identify areas where a guide may need additional clarification or updating.
We appreciate constructive reports that help improve the accuracy and usefulness of Package Size Guide.
