MULCH CALCULATOR

Draw a Plan

Draw your site as accurately as possible - graph paper works well. For odd or complex shapes, divide the area into combinations of rectangles, triangles, and/or circles.

Take Measurements

Use a tape measure, measuring wheel, or walk the perimeter of the mulch area to acquire the total length and width. This should be as close as possible but does not need to be exact down to the inch. You just want to be in the ballpark of the size to estimate the total mulch needed.

Area Calculations

Use the following formulas to determine area-

Rectangle: 

Area = length x width

Circle: 

Area = 3.1416 x radius squared

Radius is the measurement from the center point to the outside of the circle.
Radius squared is radius x radius

Triangle:

Area = (length of base x length of height) x .5
