MulchVolume

Terms of Use and Disclaimer

These terms apply when you use mulchvolume.com. They describe what the site provides, and — just as importantly — the limits of what a calculator estimate and a cited figure can tell you.

Effective September 12, 2026.

Using this site

MulchVolume is free to use. You are welcome to use the calculators and read the guides for your own projects, personal or commercial.

Please do not use the site in a way that interferes with it working for other people, or attempt to disrupt or gain unauthorised access to it.

The text, layout and calculators on this site are the site's own work. You are welcome to quote a short passage with attribution and a link. Republishing pages wholesale, or reproducing the calculators, is not permitted.

Calculator estimates

The calculators return mathematical estimates derived from the values you enter.

The arithmetic itself is deterministic: an area is multiplied by a depth, the result is converted between units using exact constants, and bag counts are rounded up to whole bags. What the result cannot do is be more accurate than the numbers you gave it.

If a bed is measured roughly, if the depth is estimated, if the bag volume is read from memory rather than from the bag, or if a price is out of date, the output will reflect that. The quantity you actually need to buy may differ from the figure shown.

Treat the result as a well-formed starting point for a purchase decision, not as a guaranteed requirement.

Materials vary

Landscape materials are not uniform products.

Bulk density, moisture content, particle size and the degree to which a material settles after it is laid all differ between suppliers, between products from the same supplier, and between deliveries. Bag and bulk volumes are not standardised across the industry. Coverage figures printed on packaging depend on the depth the manufacturer assumed.

Because of that, the volume that arrives, and the area it actually covers once spread and settled, can differ from a purely geometric calculation.

Prices, suppliers and availability

Any price or cost figure on this site is an estimate, not a quote.

MulchVolume does not sell mulch and is not a supplier. Prices, bag sizes, coverage claims, delivery minimums, delivery charges and stock availability belong to the supplier, change frequently, and vary by region and season. Nothing here is a guarantee of another company's pricing, inventory or terms.

Confirm the details that matter with the supplier before you buy.

About the sources this site cites

Where this site states something about how a material behaves, or what depth a body recommends, it names the organisation that published it and links to the original.

Those citations are accurate reports of what the named source published. What they are not is a universal product specification. A recommendation made by a horticultural authority for one climate, planting type or material grade was made in that context, and a figure from a manufacturer describes that manufacturer's own product. Where two sources differ, this site reports the difference and attributes each rather than resolving it into one number that neither source published.

So: read a cited figure as "this organisation published this, in this context", which is what it is — and not as a constant that holds for every product on every site.

Disclaimer

This site is informational. It does not provide professional landscaping, arboricultural, horticultural, engineering, safety-certification, legal or financial advice, and it is not a substitute for advice about your specific site from someone qualified to give it.

Playground surfacing in particular. The playground material on this site describes what the published safety standards say about loose-fill surfacing materials. It does not certify any installation, does not assess any particular piece of equipment, and does not determine a safe surfacing depth or fall height for a real playground. Those determinations require the applicable standard and an assessment of the actual installation by someone competent to carry it out. Do not treat anything on this site as a substitute for that.

To the extent permitted by law, MulchVolume is not liable for loss arising from use of this site — including material ordered in the wrong quantity, a purchase made on the basis of an estimate, or reliance on a third party's published figures. These terms do not limit any rights that cannot lawfully be limited.

Changes to the site and to these terms

Pages, calculators and guides on this site are revised as sources are updated or as topics are added. Content can change or be removed without notice.

If these terms change, the updated version is published on this page with a new effective date.

Effective September 12, 2026.
