How Much Does Fill Dirt Weigh?

When planning a landscaping or construction project, knowing the weight of fill dirt can help you avoid surprises — especially when it comes to cost, delivery, and how much material you actually need. Whether you're leveling out a backyard or prepping for a new patio, this guide breaks down what impacts fill dirt weight and how to calculate it with confidence.

What Is Fill Dirt?

Fill dirt is a compactable material used to build up ground elevation, fill low spots, and provide a stable base for construction. Unlike topsoil, fill dirt is typically low in organic matter, which helps prevent settling over time. It usually consists of a mix of clay, sand, and small rock particles — and the exact blend can affect its weight.

What Affects the Weight of Fill Dirt?

Fill dirt doesn’t weigh the same in every situation. Here's what can cause it to vary:

1. Moisture Content

Wet dirt is heavier than dry dirt — no surprise there. Water increases the total mass, which means that the same volume of fill dirt can weigh significantly more after rain or irrigation.

2. Soil Composition

Fill dirt with more clay tends to weigh more because clay particles are smaller and denser than sand or stone. A sand-heavy or rock-heavy blend may be slightly lighter by comparison.

3. Compaction Level

The more compacted the soil, the more it weighs per cubic yard. Loose fill dirt is lighter and fluffier. If you're planning to compact the soil after it's delivered, keep in mind that it will settle and become denser.

Average Fill Dirt Weight Per Cubic Yard

On average, dry, loose fill dirt weighs about 2,000 pounds per cubic yard. This number can range anywhere from 1,800 to 2,700 lbs depending on moisture, compaction, and composition.

How to Calculate Fill Dirt Weight

To figure out the total weight of the fill dirt for your project, you just need two numbers:

• Volume needed (in cubic yards)

• Estimated weight per yard

Then multiply:
Cubic Yards x Weight per Cubic Yard = Total Weight (lbs)

Example:
If you need 12 cubic yards of fill dirt, and it weighs roughly 2,000 lbs/yard:
12 x 2,000 = 24,000 lbs (or 12 tons)

💡 Tip: Use the built-in calculator on each Ottr product page to estimate how much material you need based on square footage and depth.
