Frequently asked questions

Is 165 inches built in?

No. The flag uses the limit you type. Carriers publish their own limits and change them.

Is this a carrier rule?

No. It only applies the length-plus-girth formula to the numbers you enter. Not shipping advice — live carrier limits and rates vary.

Is my data sent to a server?

No. This calculator runs entirely in your browser. Nothing you type is uploaded or stored by Qivtools.
