Add This Calculator to Your Website — Free
Put a working construction calculator on your own page in about a minute. Pick the tool, choose a width, preview it, and copy the embed code. No account, no API key, no cost — just keep the small attribution link.
- 1. Choose a calculator and width.
- 2. Check the live preview.
- 3. Copy the code and paste it into your page.
Height adjusts automatically to the calculator via the small script in the snippet. Without it, the frame uses a sensible fixed height and the tool still works.
Live preview
Paste this wherever HTML is allowed — a page, a post, an HTML block. On WordPress, use a “Custom HTML” block. The embed adds no link, no ads and no tracking to your page.
One small ask
There's no link baked into the widget. If it's useful to your readers, please add a credit link back to the calculator somewhere on your page — it's what keeps this free to build and maintain, and it helps other people find it.
