How to use it
- Enter the volume in cubic feet.
- Enter the desired depth in inches.
- Read the area covered and the preset depth rows.
What it does – Enter the volume in cubic feet and the desired depth in inches, and the tool instantly returns the square‑foot area you can cover. It also shows standard coverages at 1", 2", 3" and 4" depths, so you can compare options without extra math. Knowing the exact area helps you buy the right amount of mulch, sand, soil or concrete, avoiding costly over‑orders or shortfalls. The results are based on the fixed conversion that 1 cu ft spreads to 12 sq ft at a 1‑inch depth, and depth is simply inches ÷ 12 to get feet. Read the “Area Covered” line for your specific depth, then use the preset rows to see how the same volume behaves at common depths. Round the resulting area up to the nearest whole square foot for ordering, and remember the tool works on any device with a browser.

Case study
Sam needed to spread 2 cu ft of decorative stone over his patio. Using the calculator, he saw it would cover 24 sq ft at 1″ depth, so he ordered exactly enough, saving $30 on excess material.
