Dirt Calculator
Estimate how much dirt, topsoil, or fill material you need for a rectangular area. Calculate volume in cubic feet and cubic yards, approximate weight, and number of delivery loads.
Enter project dimensions
Result
Enter your dimensions to estimate the dirt required.
Measure the finished area
Use the full length and width of the space you want to fill, then enter the desired finished depth.
Allow for settling
Loose dirt often settles after placement. A 5% to 15% allowance is common for small landscaping projects.
Density varies
Topsoil, clay, sand, and wet fill can have very different weights. Adjust the density for a closer estimate.
Frequently asked questions
How many cubic feet are in one cubic yard?
One cubic yard equals 27 cubic feet.
How much does a cubic yard of dirt weigh?
It varies by moisture and soil type, but a cubic yard often weighs roughly 1,800 to 3,000 pounds.
Should I order extra dirt?
Yes. Extra material helps cover settling, uneven surfaces, compaction, and small measurement errors.
Can I use this calculator for topsoil and fill dirt?
Yes. Update the density and allowance values to match the material and project conditions.
