# Landscape Materials Estimating

How much will you need?
Estimating materials for your landscape can seem like a daunting task, but with some simple math, you can take the guess work out of ordering your landscape materials.
1. The first step in estimating soil, rock, mulch, seed or sod is to find the square footage (ft²) of the area in question. Square footage is figured by multiplying length times width. Not all areas are perfectly rectangular, so you have to be creative in your measurements. It does not have to be exact.
2. If your area is triangular in shape, you multiply the base of the triangle by the height. The product is then divided by 2. That gives you the square footage of a triangle.
3. If your area is round in shape, the formula is π(r²). Find the radius of the area (half of the diameter), then square the radius and multiply by 3.14 (pi).
4. When landscaping planting beds, it is likely that you will have to use a combination of the above formulas to determine the correct measurements.
5. Once square footage is determined, use the formulas below to determine the quantity of material needed

Once you determine the amount of material you will need for your project, add 10% to the quantity. Adding 10% allows for small errors. If you are short for your project, there will be an extra expense for additional delivery. Many of the products also have a 1 yard minimum order
