Terms
- Free for any commercial or personal site.

Notes for site owners
- The iframe is sandboxed by your browser; no top-level navigation or storage from inside the widget.
- The iframe is responsive: it fills 100% of its container width and adapts at 900px and 640px breakpoints.
- If your CMS strips iframes, copy the standalone HTML at /pages/dimensional-weight-calculator-embed and host it under your own domain — same terms apply.
