How Much Landscaping Stone Do You Need?
Before buying decorative landscaping stones, it’s important to calculate how much material your project requires. Ordering too little means extra trips to the store, while ordering too much increases your costs.
Step 1: Measure the Area
Measure the length and width of the area in feet.
Formula:
Length × Width = Square Feet
Example:
10 ft × 8 ft = 80 square feet
Step 2: Decide the Depth
Most decorative landscaping stones are installed at:
- 2 inches deep (light coverage)
- 3 inches deep (standard coverage)
- 4 inches deep (heavier coverage)
Step 3: Use This Simple Formula
To calculate cubic feet:
Square Feet × Depth (in feet) = Cubic Feet
Since inches must be converted to feet:
2 inches = 0.17 ft
3 inches = 0.25 ft
4 inches = 0.33 ft
Example calculation:
80 sq ft × 0.25 ft (3 inches) = 20 cubic feet
Quick Estimation Guide
1 ton of landscaping stone typically covers:
~100 sq ft at 2 inches deep
~80 sq ft at 3 inches deep
~60 sq ft at 4 inches deep
Always add 5–10% extra to account for settling and waste.

How to Install Decorative Landscaping Stones (Step-by-Step)
Installing decorative landscaping stones is a straightforward project that most homeowners can complete in a weekend. Proper preparation ensures long-lasting results and prevents weeds or uneven surfaces.
Step 1: Clear the Area
Remove grass, weeds, roots, and debris from the area.
Use a shovel or garden hoe to create a clean, level surface.
Step 2: Level and Compact the Soil
Rake the soil evenly and lightly compact it using a hand tamper or plate compactor.
This prevents sinking and uneven stone distribution later.
Step 3: Install Landscape Fabric
Lay high-quality landscape fabric over the soil.
This step:
- Prevents weeds
- Improves drainage
- Reduces stone mixing with soil
Secure the fabric with landscape pins.
Step 4: Add Edging
Install plastic, metal, or stone edging around the perimeter.
Edging keeps the decorative stones in place and gives the area a clean, finished look.
Step 5: Spread the Stones Evenly
Pour the landscaping stones and spread them evenly using a rake.
Aim for a depth of 2–3 inches for most decorative projects.
Step 6: Final Leveling
Rake lightly to smooth the surface and adjust any uneven spots.
Your decorative landscaping area is now complete and ready to enjoy.
