Estimate Materials Before You Order
One of the most common landscaping questions is how much material is actually needed for the job. Ordering too little can stop your project mid-install, while ordering too much can increase cost and leave you with extra material you do not need.
This page is built to help you estimate bulk landscape materials more accurately for Calgary lawn projects, planting beds, patios, pathways, drainage work, and general landscape improvements.

How to Calculate Cubic Yards
Landscape materials are usually sold by the cubic yard. To estimate the amount you need, multiply your project length by width by depth, then divide by 27.
Example Calculation
A project area that is 20 ft × 10 ft at a depth of 3 inches uses a depth of 0.25 ft.
20 × 10 × 0.25 ÷ 27 = about 1.85 cubic yards
Coverage Guide by Material Type
Different materials are installed at different depths depending on the project. These are common starting points for estimating.
Soil
- Lawn leveling: 2–3 inches
- New lawn prep: 4–6 inches
- Garden beds vary by project
Mulch
- Standard depth: 2–4 inches
- Weed control: 3–4 inches
- Avoid piling too high at plant bases
Gravel / Road Crush
- Pathways: 3–4 inches
- Driveways: 4–6+ inches
- Base layers depend on load and use
Decorative Rock
- Typically 2–3 inches
- Coverage depends on rock size
- Larger stone may need more depth
