Screed is sold by the bag of dry mortar, but you plan it by the square metre and the thickness the room needs. This calculator turns your area, thickness and screed type into the exact kilograms, bags — and cubic metres poured — to order.
Calculate the quantity →Enter your floor area and the thickness, and pick a screed type — it sets a typical consumption figure you can still edit.
Enter a floor area and a thickness to see the quantity.
Quantity = area × thickness × consumption per cm.
Figures are for the screed layer only, not the levelling compound or insulation board beneath it; a heated-floor screed is usually thicker than the 5 cm default.
Typical dry-mortar consumption per m² for each centimetre of thickness:
| Screed type | Typical consumption |
|---|---|
| Cement screed | ≈ 20 kg/m² per cm |
| Flowing anhydrite screed | ≈ 18–20 kg/m² per cm |
Work out the kilograms, bags and poured cubic metres of screed, from your area, thickness and screed type.
Plan or apply the levelling compound, insulation or flooring around the screed. Autolay's planner and robot handle the tiles, planks or laminate that go on top — not the screed, the insulation beneath it, or the curing time it needs.
Once the screed has cured, the free Autolay planner works out the tiles, planks or laminate for it — the material list and waste — from a photo of your floor plan, a BIM/IFC file or a 3D scan.
