This tool calculates how many square feet of landscape rock you need based on your desired coverage area.
How to Use the Landscape Rock Calculator
1. Enter the length of the area in feet.
2. Enter the width of the area in feet.
3. Enter the desired depth in inches.
4. Click on the “Calculate” button to view the amount of landscape rock required in cubic yards.
How It Calculates
The calculator works by converting the depth from inches to feet and then calculating the volume in cubic feet using the length and width. Finally, it converts the cubic feet to cubic yards.
Formula used:
- Volume(cubic feet) = Length(feet) × Width(feet) × Depth(feet)
- Volume(cubic yards) = Volume(cubic feet) / 27
Limitations
The calculator assumes that the area is a perfect rectangle. If the area has an irregular shape, the calculated result may not be accurate. Additionally, variations in terrain and rock compaction are not taken into account.
Use Cases for This Calculator
Calculate the Square Feet for Landscaping Area
Input the length and width of the area you want to cover with landscape rocks. The calculator will instantly give you the total square footage needed for the project, making planning easier.
Determine the Amount of Rocks Needed
After obtaining the square footage, input the desired depth of the rock layer. The calculator will provide the total amount of rocks required in cubic yards, ensuring you purchase the right quantity.
Estimate Total Weight of Rocks
If you are curious about the weight of the rocks, enter the specific weight of the rock type. The calculator will multiply the weight per cubic yard by the total cubic yardage, giving you an estimate.
Calculate Cost of Rocks
With the weight and cost per pound of rocks in mind, input the cost per pound into the calculator. It will generate the total cost for the landscaping project, making budgeting simple.
Adjust Measurements for Oddly Shaped Areas
For irregularly shaped spaces, divide the area into smaller sections, measure each section individually, and add the square footage together. The calculator will handle the rest, providing you with the total square footage required.
Compare Different Depth Options
If you are uncertain about the depth of rock needed, input various depth options into the calculator. It will display the total amount of rocks required for each depth, aiding in your decision-making process.
Incorporate Walkways or Plant Beds
If you plan to exclude certain areas like walkways or plant beds from the rock installation, subtract their square footage from the total area. The calculator will then give you an accurate square footage calculation for the remaining space.
Account for Sloped Terrain
For sloped areas, measure the length and width at the base of the slope and enter them into the calculator. It will calculate the total square footage needed for the rocky terrain, considering the slope.
Optimize Rock Size Selection
If you have specific rock sizes available, input their dimensions into the calculator. It will recommend the best rock size based on coverage area and depth, ensuring efficient use of the rocks.
Plan for Future Expansion
If you are considering expanding the landscaped area in the future, input the potential additional square footage into the calculator. It will adjust the total square footage needed accordingly, aiding in long-term planning.
