2 Inch Concrete Slab Calculator
This 2 inch concrete slab calculator instantly converts your slab's length and width into cubic yards, cubic meters, bags and estimated cost at a fixed 2-inch thickness — the depth typically used for toppings, overlays and mower strips.

Die Formel
Volume = Length × Width × 2/12 ft, then ÷ 27 for cubic yards Rechenbeispiel: A 10 ft × 10 ft slab at 2 inches: 10 × 10 × 0.167 = 16.7 ft³ ÷ 27 ≈ 0.62 yd³ before waste.
A slab poured 2 inches thick is the standard choice for toppings, overlays and mower strips. At this thickness, one cubic yard of concrete covers about 162 square feet, which makes ordering straightforward once you know your slab area.
A 2 inch slab is the thinnest practical pour and is limited to non-structural uses — resurfacing, overlays and edging strips. It is not suitable for foot-traffic slabs on grade without bonding, and never for vehicles. Consider fiber-reinforced or polymer-modified mixes at this depth to resist cracking.
Enter your dimensions above and the calculator handles every conversion — cubic feet, cubic yards, cubic meters and litres — plus the number of bags by size and a 5–10% waste allowance so you don't run short mid-pour.
Häufig gestellte Fragen
Häufige Fragen zum 2 inch concrete slab calculator.
How much concrete do I need for a 2 inch slab?
Multiply length × width in feet, then multiply by 0.167 (2 inches in feet) to get cubic feet, and divide by 27 for cubic yards. A 12 × 12 ft slab needs about 0.89 yd³.
How much area does one yard cover at 2 inches thick?
About 162 square feet. The rule of thumb is coverage (ft²) = 324 ÷ thickness in inches.
How many 80 lb bags for a 2 inch slab?
Each 80 lb bag yields ≈ 0.60 ft³. For a 10 × 10 ft slab at 2 inches (16.7 ft³) you'd need about 28 bags before waste.
Is 2 inches thick enough for my project?
2 inches suits toppings, overlays and mower strips. Thinner slabs are limited to toppings and paths; driveways need 5–6 inches and heavy-equipment pads 8 inches with rebar.
