Home/Embed a calculator

Put a working calculator on your own site

One line of HTML. No account, no framework, no tracking of your visitors.

Every calculator on RenoMath can be dropped into another website as an iframe. The maths runs inside the frame, so nothing about your visitors is sent to us and nothing you paste can collide with your own scripts or styles.

It exists because the alternative is worse for everyone. If you write about tiling a bathroom, your reader wants the number, not a link to somebody else's number. Give them a calculator on the page they are already reading, and they stay on it.

This is the real thing, loading from getrenomath.com. Type in a box and watch the frame grow.

How to add one

  1. Pick a calculator from the list below and open its page.
  2. Open Embed this calculator on your site near the bottom and press Copy code.
  3. Paste it into your page where the calculator should appear — in a CMS block that accepts HTML, or straight into the template file.

Leave the small script tag that travels with the iframe. That is what listens for the height and resizes the frame; without it the embed still works, but the number of pixels is fixed and long result lists get cut off.

What we ask

Keep the credit line under the calculator. It is the only thing we get out of this, and it is one unstyled link. Otherwise: no permission needed, no attribution in your article required, commercial and non-commercial sites both fine.

Two limits. Do not present the calculators as your own work or imply we endorse your product. And read the numbers as estimates — they use typical US material and labour costs and cannot see the actual site.
