Calculadora de Areia Online Grátis
Sand volume and weight for landscaping, concrete mix and foundation work
The Sand Calculator computes the volume and weight of sand needed to fill or cover a defined area and depth, whether you're laying a paver base, filling a sandbox, bedding a pipe trench, or mixing into concrete. It converts between cubic yards, cubic metres, and tonnes to match however your local supplier sells bulk sand.

Sobre Esta Calculadora
Sand is used in construction in several distinct forms: sharp sand for concrete mixes and mortar, soft building sand for plastering and pointing, kiln-dried sand for jointing block paving, and coarse grit sand for drainage layers. The bulk density varies between these types, which affects how much a given volume actually weighs — and therefore how many delivery bags or tonnes to order.
This calculator uses standard bulk density values for each sand type and converts your area and depth into the volume and weight figures that bulk suppliers quote. Because sand is typically sold by the tonne (metric), the weight output is the most directly useful number for ordering.
The volume figure is useful when checking whether a hired trailer or tipper truck can carry the full load in one trip. For projects involving concrete, this calculator works in conjunction with the Cement and Gravel calculators so you can estimate all three constituent materials together.
A Calculadora de Areia calcula o volume e o peso da areia necessária para preencher ou cobrir uma área definida.
Exemplo Resolvido
Sand required for a 5 m × 4 m patio paver base at 50 mm depth
Entradas:
- Length: 5 m
- Width: 4 m
- Depth: 0.05 m (50 mm compacted depth)
Passo a Passo:
- Volume = 5 × 4 × 0.05 = 1.0 m³
- Add 15% for compaction and wastage: 1.0 × 1.15 = 1.15 m³
- Dry sand bulk density ≈ 1,600 kg/m³
- Weight = 1.15 × 1,600 = 1,840 kg = 1.84 tonnes
