Free Gravel Driveway Calculator Widget
The embedded Gravel Driveway Calculator converts a driveway, path or pad into cubic yards, tons and approximate dump-truck loads, with separate base and decorative top layers and a self-haul vs. delivered-and-spread cost range. It suits aggregate and landscape-supply sites, driveway, grading and excavation contractors, and rural-property or homesteading blogs.
It's a single iframe — free, responsive, no registration, and it adds no link, ad or tracking script to your page.
Live preview
The embed adds no link, no ads and no tracking to your page. Prefer a guided version with a preview? Use the embed builder.
One small ask
Nothing links back to us from the widget itself. If your readers find it useful, please add a credit link to the Gravel Driveway Calculator somewhere on your page — that's what keeps it free to maintain and helps others discover it.
Where the Gravel Driveway Calculator widget fits
- An aggregate or stone yard's "gravel types" or delivery page
- A "gravel driveway cost" or "how to build a gravel driveway" article
- A rural-property, farm or homesteading blog
How to add it to your site
- Plain HTML: paste the snippet where you want the calculator to appear.
- WordPress: add a “Custom HTML” block and paste the snippet in. Avoid the “Paragraph” block — it strips iframes.
- Squarespace / Wix / Webflow: add an “Embed” or “Custom Code” / “HTML” element and paste the snippet.
- The second line (
embed.js) is optional — it just auto-sizes the frame height. You only need it once per page even with several calculators.
Sizing & responsiveness
Set the width to 100% to fill the column it sits in, or a fixed pixel value for a sidebar or narrow layout. Height is handled for you: with embed.js the frame grows and shrinks to fit the calculator (including after someone runs an estimate); without it, the frame stays at 900px and everything still works, just with an inner scrollbar on small screens.
Questions from site owners
Is it really free? Any catch?
Yes, free. No account, no API key, no usage limits, and no link, ads or tracking added to your page. The only thing asked is that, if the tool is useful to your readers, you add a plain credit link back to the calculator somewhere on the page.
Will it slow my page down or track my visitors?
No. The calculator loads in an iframe so it never blocks your page, it ships no third-party ad or analytics scripts onto your site, and it sets no cookies on your visitors. The optional resizer script is a few KB and loads asynchronously.
Does it give tons and truck loads, not just cubic yards?
Yes — it converts volume to tons using the chosen material's density and shows how many standard 10-ton truck loads that is, which is how suppliers actually quote and deliver.
Can readers add a decorative top layer?
Yes — the form has an optional second layer (pea gravel, river rock and so on) over the compacted base, priced separately from it.
Can I resize it or set a fixed width?
Yes. Choose responsive (100%) or a fixed-pixel width when you copy the code; height auto-fits the calculator, with a fixed fallback if the resizer script is blocked.
