Terms of Use

Last updated: November 10, 2026.

By using BoxFit you agree to these terms.

Estimates, not advice

Results are estimates based on published USPS prices and the sizes and weights you enter. They are general information, not a quote. The final postage is whatever USPS or your label provider charges at checkout, which can differ because of surcharges, measurement, zone or price changes.

Carrier names

USPS, Priority Mail, Ground Advantage and Flat Rate are trademarks of the United States Postal Service, used here only to identify its services. We are an independent site and are not affiliated with or endorsed by USPS or any shipping company.

No warranty and limitation of liability

The site is provided "as is". To the fullest extent permitted by law, we are not liable for any loss arising from use of, or reliance on, the site.

Ads and links
