How Many Concrete Blocks To Build A Garage

The majority of single-car garages are between 12×20 and 24×24 feet, with two-car garages typically measuring 24×24 to 24×30 feet. The number of concrete blocks required to build a garage will vary depending on the size of the garage, the thickness of the walls, and the size of the blocks used.

Size of the Garage

The first step in determining how many concrete blocks you need is to calculate the square footage of the garage. To do this, multiply the length of the garage by the width. For example, a 24×24 foot garage would have a square footage of 576 square feet.

Thickness of the Walls

The next step is to determine the thickness of the walls. Concrete block walls can be 4, 6, or 8 inches thick. The thicker the walls, the more blocks you will need.

Size of the Blocks

Concrete blocks come in a variety of sizes. The most common size is 8×8×16 inches. However, you can also find blocks that are 4×8×16 inches, 6×8×16 inches, and 10×8×16 inches. The size of the blocks you use will affect the number of blocks you need.

Calculating the Number of Blocks

Once you have determined the size of the garage, the thickness of the walls, and the size of the blocks, you can calculate the number of blocks you need. To do this, multiply the square footage of the garage by the thickness of the walls, and then divide by the square footage of the blocks. For example, a 24×24 foot garage with 6-inch thick walls and 8×8×16-inch blocks would require 1,728 blocks.

Additional Considerations

In addition to the number of blocks, you will also need to purchase mortar, rebar, and other materials. You should also factor in the cost of labor if you are not planning to build the garage yourself.
