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 plus a one-line credit link — free, responsive, no registration, and no ads or tracking scripts on your page.

Why add it to your page
Gravel is sold by the ton, but people measure a driveway in feet. The calculator bridges that gap, so a reader reaches your order form or phone line already knowing the tons and truck loads they need.
What your visitors get
A 60 x 12 ft driveway with 4 in of crusher run comes back as:
- Base layer: Crusher Run (compactable base): 14.52 tons
- Bulk material estimate (self-haul): $508 – $799
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

Questions from site owners
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.
Which stone types are included?
Crushed stone (#57), crusher run, pea gravel and river rock. Each has its own weight per cubic foot, so the tons change with the stone a reader picks.
