Concrete Slab Calculator
To use the Concrete Volume Calculator, simply enter the width, length, and thickness of your pour. The calculator will automatically estimate the number of cubic yards of concrete that will be required. Concrete is ordered by volume in cubic yards.
Tips for Ordering Concrete
Quantity – Measurements can frequently be a little off, so we highly recommend ordering a little extra, because coming up short can be a disaster.
Calculator Use
Calculate volumes for concrete slabs, walls, footers, columns, steps, curbs and gutters. Enter dimensions in US units (inches or feet) or metric units (centimeters or meters) of your concrete structure to get the cubic yards value of the amount of concrete you will need to make this structure.
Curbs & Gutters
We calculate the volume in sections from the ground to the top of each section. The Curb and Gutter are each a section.
Why use this calculator?
In any construction work at the planning stage, it is important to correctly calculate the amount of materials needed, because it allows you to avoid problems with shortages and additional trips to the store, and also allows you to save money if you prefer to buy with a large reserve.
How does it work?
You fill in the fields: Length, Width, Thickness in the Slab Size section.
