How to Use a French Drain Calculator?
Measure The Area:
- Length: The length of the trench.
- Width: Typically, a width of 6 inches works well.
- Depth: The standard depth is around 18 inches, but adjust it as needed.
Calculate Volume:
- Volume Calculation Formula
To calculate the volume of a trench for a French drain, use the formula:
- Volume=Length×Width×Depth
Example Calculation
If your trench is 30 feet long:
Length: 30 feet
Width: 0.5 feet
Depth: 1.5 feet
The volume calculation would be:
Volume=30×0.5×1.5=22.5cubic feet
Decide Materials:
- Gravel: Calculate how much gravel you will need based on the volume.
- Pipe: Choose a perforated pipe to allow water to flow through.
Real-Life Applications
Homeowner Scenario:

FAQs about French Drain Calculator
To calculate the size of a French drain, determine the length and width of the trench, ensuring it’s at least 6 inches wide and deep enough to accommodate the pipe and gravel for effective drainage.
For a 100-foot French drain, approximately 1.5 to 2 tons of gravel are needed, depending on the size of the gravel and the depth of the trench, which typically requires 6-12 inches of gravel coverage.
The area covered by a French drain depends on its length and width; for example, a standard 6-inch wide drain will cover about 0.5 square feet for every linear foot installed.
The maximum depth for a French drain is typically 6 to 8 feet, but it’s important to consider local regulations and soil conditions to prevent collapse and ensure effective drainage.
