Estimates, not guarantees
The calculators and guides on Mulch Calculators are free tools for planning. Results depend on the measurements you enter and on typical figures (bag sizes, bale coverage, weights) that vary by product and supplier. Confirm quantities and specifications with your supplier before you buy.
Safety
Playground surfacing depths on this site come from published guidance and are a starting point only. Follow the equipment and surfacing manufacturers’ instructions and any rules that apply to your playground. Check your vehicle’s and trailer’s load ratings before hauling mulch.
No professional advice
Nothing on this site is professional landscaping, engineering or safety advice. For a specific property, talk to a qualified local professional.
