How to use it
- Enter the area in square feet.
- Enter the desired depth in inches.
- Click Calculate to see cubic feet and cubic yards.
- Use the results to order the right amount.
What it does – You enter square footage and desired depth in inches. The tool converts depth to feet, multiplies by area to give volume in cubic feet, then divides by 27 to show cubic yards. Why it matters – Ordering too little means a half‑finished garden; ordering too much wastes money and space. Knowing both units lets you compare supplier quotes that use different measurements. How to read – The cubic‑feet number is the raw volume; the cubic‑yard figure is the same volume expressed in the standard bulk‑order unit (1 yd³ = 27 ft³). Use the rounded values for ordering, then add a small waste factor. If you have a sloped area, calculate each flat section separately and add the results. The calculator works instantly on any device, so you can take the numbers to the store or share them with a contractor.
Pro tips
- Add 5‑10% extra for compaction and spillage.
- Round up to the nearest 0.1 yd³ for easier ordering.
- Order in bulk yards when possible to reduce delivery fees.
- Double‑check depth conversion: inches ÷ 12 = feet.
Real-life examples
- A homeowner plans a new flower bed and needs to know how much mulch to buy.
- A contractor estimates rock fill for a driveway base.
- A landscaper quotes a client for a sloped garden renovation.
Case study
Sarah entered her 800 sq ft patio and a 2‑inch depth. The calculator returned 1.48 yd³ (40 ft³). She ordered 1.5 yd³, avoided a costly shortfall, and finished the project on schedule.
