Overbuying wastes money; underbuying wastes a trip to the store. A 10×10 ft concrete slab that's 4 inches thick needs about 1.24 cubic yards of concrete — roughly 62 eighty-pound bags with waste allowance. Without a calculator, most people guess and get it wrong. Our tools use standard US material coverage rates so your estimate matches what contractors use.

Frequently asked questions
Are these calculators really free?
Yes — every calculator on MeasureMate is free, with no account, no signup and no limits.
Do the estimates include waste?
Yes. Results include a 10% waste allowance, which is the standard buffer contractors use for cutting, spills and breakage.
Are the coverage rates US standard?
Yes. We use standard US coverage rates — e.g. one gallon of paint covers ~350 sq ft, an 80 lb bag of concrete yields 0.6 cu ft.
