Formula used
Sand volume = Total volume × (Sand parts ÷ Total parts)
Example: 2 m³ mix at 1:2:4 ratio → sand volume ≈ 0.571 m³.
How to use this calculator
- Enter Total mix volume (m³), Sand parts (e.g. 2 in a 1:2:4 mix), Total ratio parts (e.g. 7 for 1:2:4).

FAQ
Frequently asked questions
What does the ratio represent?
The proportion of sand relative to the other materials (cement, aggregate) in your mix, by volume.
Should I add extra for compaction or wastage?
This gives the exact theoretical volume — many builders add 5-10% extra in practice.
How do I find cement and aggregate quantities too?
Use the Cement Calculator with the same total volume and the cement ratio part.
Does sand type affect the calculation?
No, the volume-based ratio calculation is the same regardless of sand type.
