Plan the work
before the work.
Measure materials with formulas you can follow. FigureNest’s construction tools turn a tape measure and a few supplier details into a useful first estimate.
Know what to buy
before you buy it.
These estimates are built around the decisions that cause the most waste: thickness, coverage, cuts, slope, spacing, and supplier units. Enter your measurements, keep an allowance that matches the job, and compare the result with the product label or local quote.

Open calculatorWalls & Building Materials
Use the result to make a plan, not to skip the plan.
Material quantities vary with grade, product coverage, soil, code, access, and the shape of the job. Every calculator shows its method so you can see what is included and what still needs a supplier or professional check.
