Calculating the Square Footage of Your Landscape: A Guide for Different Shapes and Landscaping Materials
San Diego Rock Supply is known for its wide variety of quality landscaping materials. Whether you are redesigning a backyard oasis or simply adding a new pathway, having the correct amount of material is crucial. Too little and your project comes to a standstill, too much and you’ve overspent on unnecessary resources. But how do you determine the amount of material you need? It all starts by calculating the square footage of your landscape area. Here’s how to do it for various shapes and landscaping materials:
Step 1: Understand Your Space
Begin by measuring the length and width of your landscaping area. If your area is irregular in shape, try breaking it down into smaller rectangles, squares, circles, or triangles. For curved areas, consider them as circles for the sake of simplicity.
For squares and rectangles: the area is calculated by multiplying the length by the width (Area = Length x Width)
For circles: the area is calculated by squaring the radius (half the diameter of the circle) and multiplying by pi (3.14) (Area = Pi x Radius^2)
For triangles: the area is calculated by multiplying the base by the height and then dividing by two (Area = Base x Height / 2)
Step 2: Determine Landscaping Material Quantity
Different landscaping materials cover different areas, even when measured in equal quantities. Let’s examine how to calculate for some popular materials:

Mulch or Soil
A cubic yard of mulch or soil typically covers about 100 square feet at a depth of 3 inches. Therefore, divide your total area by 100 to find out how many cubic yards you need for a 3-inch layer. If you want a different depth, adjust accordingly.
Decorative Rocks or Gravel
To calculate the amount of decorative rocks or gravel, you need to know the desired depth in inches (typical depth ranges from 2 to 4 inches for most projects). Here’s the formula to calculate in cubic yards: (Area in square feet x Depth in inches) / 324.
Step 3: Always Factor in Extra Material
Remember, it’s always better to have a little extra material than not enough. Professionals typically recommend ordering an additional 10-20% of material to account for cutting losses, compaction, and future touch-ups.
Calculating the square footage of your landscape areas can seem like a daunting task, but with these simple steps and formulas, you can get a pretty accurate estimation.
