Put Our Calculators on Your Website, Free
One snippet, one working calculator. No signup, no cost, no catch.
Every calculator on Sizeaholic can be embedded on your own website. The embed is the same calculator that runs here: the same formulas, the same cited sources, and the same privacy design. Nothing your visitors type is stored or transmitted, ever. When we improve a calculator, your embed updates automatically.
The fastest way
Open any calculator on this site and click the </> Add to your website button below it. A ready-to-paste snippet appears. Copy it into your page's HTML and you are done.
The snippet
Prefer to build it by hand? This is the whole thing. Replace SLUG with a calculator slug from the table below:
<iframe src="https://sizeaholic.com/embed/SLUG/"
style="width:100%;max-width:520px;height:520px;border:1px solid #e3e8f0;border-radius:12px;"
title="Calculator" loading="lazy"></iframe>
<p style="font-size:13px;">Calculator powered by
<a href="https://sizeaholic.com/SLUG/">Sizeaholic</a></p>The 520px height suits most of our calculators. If one needs more or less room on your page, adjust the height until it fits without an inner scrollbar.

The license, in plain words
Embedding is free for any website, commercial or personal. Keep the attribution link under the calculator, use the snippet as provided, and do not present the calculator as your own work. The full wording lives in our Terms of Use. That is the entire deal.
Privacy inside the embed
An embedded calculator behaves exactly like the one on our site. All math runs in the visitor's browser, and nothing they type is sent anywhere. Our privacy policy applies to the calculator itself; your site's policy covers the page around it.
