When you start planning a project that involves landscaping rock, a common question that we ge t asked is, how much landscaping rock do I need?
Calculating this accurately can save you a bunch of money and headaches.
You don’t want to order too much as you will waste money and all that extra labor spreading it around. If you order too little, you won’t have enough to cover the landscape adequately.
There aretwo main factors you need to consider when calculating how much landscaping rock you need for your project:
 The size of the project area you will be covering
 How deep you want the rock to be
Tools you will need:
 Measuring Tape
 Calculator
Tip
Use rock as mulch only in beds for plants that require minimal moisture like alpine plants and cacti.
Install barriers around rock areas that are next to yards. This will keep the rock in its area and keep it from spilling over onto your lawn, where it could cause extensive damage to your lawnmower.

Determining the Size of Area
Step 1: Inspect the Area
The first piece of information you need to know is the shape and dimensions of your lawn, particularly the width and length. You will want to measure and multiply the area length times the width in feet until the square footage is 1,000 sq. ft. and mark off this area with the help of a marking tool like washable paint or objects to distinguish the treatment areas border line.
Step 2: Convert Measurements
If your yard is rectangular or square, measure the length and width then multiply together (length X width = square footage). For example, if your yard has a length of 10 feet and width of 8 feet, you would multiply 10 by 8 to get 80 square feet.
Be aware for triangle shaped lawns, you will measure the length and width, multiply together, then divide by two ( length X width / 2 = square footage).
If your lawn is a not a perfect rectangle, break the lawn into different sections to measure more easily, then add measurements together to get the area’s total square footage.
For treatment areas with flowerbeds and other obstructions in the yard you will measure the square footage of the object and subtract from your yards total square footage.
Example, you have a property that is 12,000 sq. ft. and in the middle you have a landscape bed with a length of 3 feet and width of 2 feet. You will multiply 3 by 2 to get 6 feet, then subtract from your yard total.
 3 ft. X 2 ft. = 6 sq. ft.
 12,000 sq. ft. – 6 sq. ft. = 11,994 sq. ft.
Therefore, you will treat an area with 11,994 sq. ft.

Circle
The area of a circle is the radius squared (r^{2}) multiplied by π = 3.14. The radius is equal to onehalf the diameter of the circle.
Area = π r^{2}
Area = (3.14)r^{2}
Example 2:
Calculate the area of a circle with a radius of 30 ft.
Area = (3.14)r^{2}
Area = (3.14)(30 ft)^{2} remember, square the radius first then multiply by 3.14
Area = 2,826 ft²

I never would have thought to use Google Maps to measure my lawn!! This is SUCH a helpful tip! Now I don’t have to go out and buy one of those measuring wheels!! Thank you so much!!!

Triangles
The area of a triangle is onehalf the base (b) multiplied by the height (h).
Area = [(b)(h)] / 2
Example 4:
Calculate the area of a triangle where the base is 60 ft and the height is 30 ft.
Area = [(b)(h)] / 2
Area = [(60ft)(30ft)] / 2
Area = 900 ft²
