Formula
The Floor Screed Calculator uses the formula:
Screed volume = Floor length × Floor width × Screed thickness ÷ 1000
Worked example
For example, with floor length of 10 m, floor width of 5 m, screed thickness of 50 mm and screed density of 2.2 t/m³, the screed volume is 2.500.
| Floor length | 10 m |
|---|---|
| Floor width | 5 m |
| Screed thickness | 50 mm |
| Screed density | 2.2 t/m³ |
| Screed volume | 2.500 |
|---|---|
| Screed weight | 5.50 |

Frequently asked questions
Multiply floor area by thickness. A 10×5 m floor at 50 mm needs 2.5 m³ of screed.
Bonded screed is often 25–40 mm; unbonded or floating screed is usually 50–75 mm.
At about 2.2 t/m³, 2.5 m³ of sand-cement screed weighs around 5.5 tonnes.
Yes. Add a small margin for uneven sub-floors and wastage during mixing and laying.
