How Much Does a Cubic Metre of Sand Weigh?

Understanding Sand Weight Per Cubic Metre

Sand is one of the denser landscape materials commonly used in residential projects, making weight a crucial consideration for transport and handling. Standard washed sand weighs approximately 1.5 tonnes per cubic metre. The calculator above confirms this by showing that one cubic metre of washed sand comes to 1.5 tonnes, or 1,500 kilograms. This makes sand comparable in weight to gravel and significantly heavier than mulch or most garden soils.

Understanding this weight is essential when planning how to get sand to your project site. A small trailer rated at 750kg can safely carry only half a cubic metre of sand. Even a tandem trailer rated at 2 tonnes handles roughly 1.3 cubic metres before reaching its limit. For most sand projects, bulk delivery makes practical sense given these weight constraints.

Moisture Affects Weight

Sand weight varies with moisture content. Dry sand weighs less than wet sand, and sand that has been sitting in the rain can be significantly heavier than the nominal 1.5 tonnes per cubic metre. Suppliers typically quote weights based on normally moist sand, not oven-dried or saturated material. This variation is why ordering by volume rather than weight remains standard practice, though delivery tickets often show both measurements.

Weight Per Bag Reference

For those buying sand in bags, standard 20kg bags are common at hardware stores. One cubic metre of sand equals approximately 75 bags at 20kg each. This adds up quickly for larger projects, with a simple sandpit needing over 50 bags and a medium paving job potentially requiring well over 100 bags. Beyond a few hundred kilograms, bulk delivery almost always proves more economical and saves enormous handling effort.
