Calculadora de Mantillo y Tierra
Calcule las yardas cúbicas, pies cúbicos, metros cúbicos y número de bolsas de mantillo, compost o tierra negra necesarias para canteros y jardines.
Calculate cubic yards, cubic feet, tons, and bags needed for garden beds, landscaping borders, and raised planters.
Acerca de Calculadora de Mantillo y Tierra Vegetal (Yardas y Bolsas)
Planning landscaping projects, garden renovations, and raised bed installations requires calculating bulk material volumes accurately. Underestimating soil or mulch purchases leads to frustrating mid-project supply runs, while overestimating results in expensive wasted material left piled on driveways.
Bulk landscaping materials like shredded bark mulch, compost, screened topsoil, and gravel are sold by the cubic yard in bulk quantities, or in individual bags measuring 1.5, 2.0, or 3.0 cubic feet at retail garden centers. Converting square footage and depth into purchase quantities is prone to calculation errors.
This Mulch and Topsoil Coverage Calculator estimates exact volume requirements in cubic yards, cubic feet, and metric cubic meters for rectangular, circular, triangular, and irregular garden beds. It includes density-based tonnage estimates and calculates exact bag purchase counts.
To calculate lawn nutrition needs after laying new topsoil, explore our fertilizer calculator. For hardscaping projects involving walkways or patio sub-bases, test the gravel calculator.
Especificaciones de ingeniería y detalles de ejecución
Cubic yard volume formula for rectangular beds: (Length in feet * Width in feet * (Depth in inches / 12)) / 27.
Cubic yard volume formula for circular beds: (π * (Radius in feet)^2 * (Depth in inches / 12)) / 27.
Bag count formulas: Total cubic feet divided by nominal bag volume, rounded up to the next integer to avoid shortages.
Bulk material density factors: Dry shredded bark mulch (~600 to 800 lbs/yd³), damp compost (~1,000 to 1,200 lbs/yd³), screened topsoil (~2,000 to 2,200 lbs/yd³).
Includes an optional 10% settling and compaction contingency factor recommended for loose, fibrous organic materials.

Casos de uso comunes en producción
- Homeowners determining how many bags of colored mulch to purchase from local home improvement centers for spring landscape maintenance.
- Gardeners building raised vegetable planter boxes and calculating the necessary topsoil and compost blend ratios.
- Professional landscaping contractors preparing customer estimates and bulk truckload delivery orders from wholesale soil yards.
Casos extremos y límites operativos
- Material compaction: Freshly delivered loose bark mulch compresses by 10% to 15% after watering and natural settling. Selecting the compaction contingency ensures proper final depth.
- Irregular bed perimeters: For winding curved landscape borders, break the space into modular rectangular segments and sum the square footage into the Direct Area mode.
Preguntas Frecuentes
How deep should mulch be in flower beds?
A layer of 2 to 3 inches is ideal for standard flower beds and around trees. Applying less than 2 inches allows sunlight to germinate weed seeds, while applying more than 4 inches can suffocate plant root systems and retain excessive moisture.
How many bags of mulch equal 1 cubic yard?
One cubic yard equals 27 cubic feet. Therefore, 1 cubic yard equals exactly 13.5 bags of 2.0 cubic foot mulch, 18 bags of 1.5 cubic foot mulch, or 9 bags of 3.0 cubic foot mulch.
How much does a cubic yard of topsoil weigh?
A cubic yard of dry, screened topsoil typically weighs between 2,000 and 2,200 pounds (approximately 1 to 1.1 US tons). Wet topsoil can weigh significantly more, reaching up to 2,700 pounds.
