How to use it
- Enter the desired depth in inches.
- Click Calculate.
- Read the area covered in square feet and square yards.
What it does – The calculator tells you the surface area you can spread one cubic yard (27 ft³) of soil at any depth you specify. Why it matters – Knowing the exact coverage prevents over‑ordering costly fill or under‑ordering that leaves gaps. How to read it – The result appears first in square feet, the standard unit for landscaping, then converted to square yards (1 yd² = 9 ft²). Simply divide the 27 ft³ volume by the depth in feet to get square feet, then divide by 9 for square yards. Use the numbers to plan garden beds, lawn levelling, or a new patio foundation. If you need to cover a larger project, multiply the single‑yard result by the number of yards you plan to purchase. The calculator updates instantly as you change the depth, so you can compare different design options side‑by‑side. Remember that compacted soil settles, so adding a small buffer ensures you have enough material for a smooth finish.
Pro tips
- Add 5‑10 % extra dirt to account for compaction and spillage.
- Round up the area to the nearest whole square yard for ordering ease.
- Measure depth at several points and use the average for a more accurate estimate.
- Order a full cubic yard even if you need slightly less; it’s often cheaper per unit than multiple small loads.
Real-life examples
- Planning a 4 × 8 ft garden bed and need to know how deep you can spread one yard of topsoil.
- Estimating fill for a driveway repair where the contractor asks for the coverage per yard.
- Sizing soil for a new lawn that requires a 2‑inch base layer before seeding.
Case study
Emily wanted a 6‑inch deep raised bed for vegetables. Using the calculator, she saw one yard of soil would cover 54 ft² (6 yd²), matching her 6 × 9 ft design, so she ordered exactly one yard and avoided extra cost.
