A bag of sand is usually 25 kg or 40 kg , depending on the supplier and country. Smaller bags can be 1 kg, 10 kg, 20 kg, or 25 kg , while bulk bags are much heavier and often around 850 kg to 1,000 kg.

Typical bag sizes

  • 1 kg to 2.5 kg : small classroom or hobby bags.
  • 10 kg to 25 kg : common retail bag sizes.
  • 35 kg to 40 kg : also common for construction sand bags.
  • Bulk bag : often around 850 kg or roughly 1 tonne.

Quick estimate

If you just need a rough answer, use 25 kg per bag as the most common estimate for standard sand bags.

Example

A 4-bag purchase at 25 kg each would give you about 100 kg of sand.
