Concrete calculator

For projects around the home like patio slabs, fence posts, walkways, and more, you'll need to know how to calculate how much concrete you need.

Online calculators and tables are helpful. But those calculators are often tied to specific brands.

How much is a yard of concrete

Once you know how to calculate concrete needs, you can apply this skill to any type of concrete, any brand, any project.

How to Calculate Concrete

First figure out how much space you need to fill with concrete.

After that, figure out how many bags of dry concrete you need to fill that space.

Using the example of pouring a long, narrow concrete slab for a backyard chicken coop helps you learn how to calculate concrete.

1. Measure the Project Area

   How long and wide is the project's space?

Measure the length of one side, then measure the length of an adjoining side. Multiply the two figures to arrive at the area.

Example: The chicken coop's slab will be 20 feet long and 5 feet wide. Multiply 20 by 5.

The area is 100 square feet.

7. Determine the Project Depth
