Considerations Before Building
Before calculating the number of cinder blocks needed, it’s essential to consider a few factors:
– The size and shape of your raised garden: This will directly influence the number of blocks required.
– The height of your raised garden: Taller gardens require more blocks.
– The pattern or design: Some designs may require additional blocks for stability or aesthetics.
Calculating the Number of Cinder Blocks Needed
To calculate the number of cinder blocks needed, you must first determine the dimensions of your raised garden and the height you wish to achieve. A standard cinder block is 8 inches long, 8 inches wide, and 16 inches long (though dimensions can vary slightly by manufacturer).
Determining the Garden Dimensions
- Decide on the length, width, and height of your garden. For example, let’s consider a garden that is 12 feet long, 4 feet wide, and 2 feet high.
- Convert these dimensions into inches to match the dimensions of the cinder blocks. So, 12 feet is 144 inches, 4 feet is 48 inches, and 2 feet is 24 inches.
Calculating the Total Number of Blocks
To calculate the total number of blocks needed for the walls of the garden:
– Calculate the perimeter of the garden in inches. For a rectangular garden, this would be 2(length + width). So, 2(144 + 48) = 2*192 = 384 inches.
– Since each block is 8 inches wide, divide the perimeter by the width of one block to find how many blocks are needed for one course (layer) around the garden. So, 384 / 8 = 48 blocks for one course.
– Since our garden is 24 inches high, and each block is 8 inches high, we need 24 / 8 = 3 courses of blocks.
– Multiply the number of blocks needed for one course by the number of courses to get the total number of blocks for the walls. So, 48 blocks/course * 3 courses = 144 blocks.
Adding Blocks for Corners and Stability
It’s also a good idea to add a few extra blocks for corners and for any additional support that might be needed, especially if you’re creating a complex design or a very tall garden. A general rule of thumb is to add 10% to your total for extras.
Conclusion and Final Considerations
Calculating the number of cinder blocks needed for a raised garden involves understanding the dimensions of your garden, the height you wish to achieve, and considering any additional blocks needed for stability or design. By following the steps outlined in this article and doing the math based on your garden’s specifications, you can accurately determine how many cinder blocks you need.

The dimensions of the raised garden will also influence the number of cinder blocks needed. For instance, a garden with a larger surface area will require more cinder blocks than a smaller one. Additionally, the height of the raised bed will also impact the total number of blocks needed, as a taller wall will require more blocks than a shorter one. By considering these factors, gardeners can make informed decisions about the materials needed for their raised garden, ensuring a successful and thriving outdoor space.
How do I calculate the number of cinder blocks needed for the sides of my raised garden?
Calculating the number of cinder blocks needed for the sides of a raised garden involves determining the total linear footage of the sides. This can be done by adding the lengths of all four sides of the garden. Once the total linear footage is calculated, the number of blocks needed can be determined by dividing the total linear footage by the length of a single cinder block. For example, if the total linear footage of the sides is 40 feet and each cinder block is 8 inches long, the calculation would be 40 feet x 12 inches/foot / 8 inches = 60 blocks.
It is crucial to consider the corners of the raised garden when calculating the number of cinder blocks needed. Two blocks are required for each corner, one for each side that meets at the corner. Therefore, the total number of blocks needed for the corners should be added to the total number of blocks needed for the sides. This ensures that the raised garden has a sturdy and well-constructed frame. By taking the time to accurately calculate the number of cinder blocks needed for the sides and corners, gardeners can create a raised garden that is both functional and visually appealing.
What role does the height of the raised garden play in calculating the number of cinder blocks needed?
The height of the raised garden is a critical factor in calculating the number of cinder blocks needed. As the height of the raised bed increases, the total number of blocks required also increases. This is because taller walls require more blocks to achieve the desired height. To calculate the number of blocks needed for the height, gardeners should divide the height of the raised bed by the height of a single cinder block. For example, if the raised bed is 3 feet tall and each cinder block is 8 inches high, the calculation would be 3 feet x 12 inches/foot / 8 inches = 4.5 blocks per layer.
The height of the raised garden will also influence the number of layers of cinder blocks needed. Each layer of blocks will require a specific number of blocks, depending on the length and width of the garden. By calculating the number of blocks needed for each layer, gardeners can determine the total number of blocks required for the entire raised garden. It is essential to consider the height of the raised garden and the number of layers needed to ensure that the structure is stable and can support the weight of the soil and plants.
