Terms of use

File Preflight provides planning calculators and educational information. The results are estimates, not production guarantees.

Use of the tools

You may use the calculators for personal or commercial project planning. You remain responsible for confirming final dimensions, materials, tolerances, shipping rules and supplier specifications before purchasing or producing anything.

No warranty

The site is provided “as is.” We work to keep formulas and explanations accurate, but printing processes, platform rules, carrier divisors and material specifications can change.

Intellectual property

The File Preflight interface, editorial text and original calculator implementation may not be republished as a competing site. Individual calculated results may be used freely in your projects.

Acceptable use

Do not attempt to disrupt the service, automate abusive traffic, misrepresent the site, or use it in a way that violates applicable law.
