EMBED

Put these calculators on your site

Every calculator here can be embedded with one line of HTML. Free with a link back, or white-labeled with your own colors and no attribution.

The code

Copy this, change the tool slug, and drop it into your page. The calculator runs entirely in the visitor’s browser, so it adds no load to your server and sends nothing to ours.

<iframe
  src="https://freightfigure.com/embed/linear-feet-calculator/"
  width="100%"
  height="720"
  style="border:2px solid #14213D"
  title="Linear Feet Calculator"
  loading="lazy"
></iframe>

Set the height to suit the tool. Simple calculators sit comfortably around 640 pixels; the ones with piece lists, such as freight density and IFTA, want more like 900.

Free tier

Free to embed on any site, including commercial ones, on one condition: the “Powered by FreightFigure” link stays visible and stays followable. That link is what pays for keeping the rule tables current.

You also get every rule update automatically. When a carrier changes a divisor or the NMFTA revises the scale, your embed updates with ours, with no work at your end.

White label

A licensed version removes the attribution and accepts a accent parameter so the calculator picks up your brand color, plus units=imperial|metric to set the default unit system.

Licensing is priced per site and per tool count. Tell us which calculators you want and where they will live, and we will quote it. Write to hello@freightfigure.com with the subject “White label”.

Notes

  • Embed pages are noindex, so they will not compete with your own pages or ours in search.
  • They carry no ads and no analytics of yours. We count embed page views the same way we count everything else.
  • Calculations happen on the visitor’s device. Nothing they type is transmitted anywhere.
  • Use loading="lazy" so the iframe does not affect your page speed scores.
