Editorial policy

Published October 1, 2026

What we publish

PixelSizes publishes dimension calculators, factual size references and original print-preparation tutorials. Articles focus on a complete task, using explicit input values and a related calculator. We do not publish invented product tests, customer reviews, professional credentials or printer endorsements.

Sources and original examples

Unit definitions and reference dimensions are attributed to technical and primary sources on our sources page. Worked calculations and diagrams are created for this site. An external source supports the fact described; it does not endorse our tool or guarantee a result from a particular printer. We distinguish exact definitions, displayed rounding and practical judgments.

How content is prepared

AI assistance is used in drafting and software development. Numerical examples are checked against explicit formulas and reproducible calculation tests. That process does not replace qualified print advice or a physical proof. Editorial bylines identify this website, not an invented individual specialist or a claimed independent professional review.

Publication and updates

Publication dates identify when an article is added. A modified date changes when its content is substantively revised, rather than whenever the website is rebuilt. Older source-review dates are retained until those references are checked again. The methodology records numerical limits and rounding rules.

Corrections

For a possible error, record the page, exact passage or numerical inputs, expected result and supporting source. Our contact page lists the available correspondence route. Substantive corrections should explain what changed and update the affected example or test as well as the prose. Do not send private images to report an arithmetic issue.

Advertising and independence

This edition has no advertisements, sponsored articles or affiliate links. If commercial relationships are added, they must be disclosed and visually separated from calculator controls and editorial content. A link to a technical reference is a citation, not a paid recommendation.

Scope of the advice

We calculate dimensions and geometry. We do not assess image focus, color profiles, legal rights, printer compatibility or a provider’s production tolerances. Use the actual product specification for bleed, margins, file type and print density, and inspect a proof when the outcome matters.
