How to Estimate How Much Fill Dirt You Need by Hand

If you prefer to estimate the amount of dirt you need manually, here's a simple formula to follow for a rectangular landscaping project:

Cubic Yards = (Square Feet * Thickness in Inches) / 324

  • Square Feet (sqft): Measure the area's length and width in feet, and multiply them to find the square footage.
  • Thickness in Inches: Decide how deep you want the dirt layer to be in inches.
  • Calculate: Divide the result by 324 to obtain the cubic yardage needed.

While our online calculator simplifies the process, this formula can come in handy when you want to double-check or perform calculations without an internet connection.

Common Yard Shape Area Formulas

If you do not know the area of your yard or specific areas within it, you'll need to use different formulas based on the shape. Here are quick guidelines for calculating the area of common yard shapes:

Rectangle or Square Area = Length * Width

Circle Area = 3.14 * Radius2

Triangle Area = (Base * Height) / 2

These formulas will help you calculate the area accurately, ensuring you have the necessary information to use our topsoil calculator effectively.

An Overview of Topsoil

Topsoil is the upper layer of soil that contains essential nutrients, organic matter, and microorganisms necessary for plant growth. It plays a crucial role in landscaping and gardening, providing a fertile medium for plants to thrive. Topsoil typically consists of a combination of minerals, organic material, water, and air.

Fill Dirt is an alternative to topsoil and has a lower density of nutrients and is mainly a combination of natural ingredients such as sand, gravel, and rock. Because of this, fill dirt is much cheaper than topsoil and is mainly used to raise up certain parts of land.

Common Topsoil Types and Price Table (per Cubic Yard)

Here's a brief overview of common top soil types and their approximate prices per cubic yard:

Topsoil Type Price (per Cubic Yard)
Screened Topsoil $20 - $40
Organic Topsoil $30 - $50
Fill Dirt $10 - $25
Garden Mix Topsoil $40 - $60
Sand $25 - $55
