How Much Gravel Do I Need for a 10x12 Shed?

How much gravel do I need for a 10x12 shed? You'll need about 3 cubic yards of gravel to ensure a stable and durable foundation. This amount provides the right support and drainage for your shed.

In this article, we'll guide you through the process and explain why a good gravel base is essential.

In our experience at Homestead Supplier, a solid foundation is key to the success of your shed-building project. Let's dive in and explore how to calculate and lay the perfect gravel base for your 10x12 shed.

How Much Gravel Do I Need for a 10x12 Shed?

For a 10x12 shed, you'll need approximately 3 cubic yards of gravel. This amount ensures that you have a solid and level base that can support the weight of the shed and its contents.

Here's a simple breakdown:

  1. Calculate The Area: The area of your shed base is 10 feet by 12 feet, which equals 120 square feet, in the same way that 8x10 shed square footage is 80 square feet.
  2. Depth Of Gravel: We recommend a gravel depth of 4 inches. This provides adequate support and drainage. If you prefer metric, that's about 10 centimeters.
  3. Convert To Cubic Yards: To calculate the volume in cubic yards, use the formula:

For our 10x12 shed:

120 sq ftX(4 in÷12 in/foot) = 40 cubic feet

Since there are 27 cubic feet in a cubic yard:

40 cubic feet÷27 cubic feet per cubic yard ≈ 1.48 cubic yards

To be safe and allow for some extra gravel, rounding up to 3 cubic yards is a good practice. When purchasing any supplies for a shed, we always recommend buying a little bit more than you think you need.

This is also true when deciding how many sheets of plywood do I need for a 10x12 shed floor.

Why Gravel Matters

From our experience, a gravel foundation offers several benefits:


Gravel allows water to drain away from the shed, preventing water damage and extending the life of your cedar shed or ez shed.


A well-compacted gravel base provides a stable foundation, reducing the risk of your shed shifting or sinking over time.

Level Surface

It's easier to level gravel than soil, ensuring your shed sits evenly and doors open and close properly.

How to Lay Your Gravel Foundation

Here are some quick tips for successfully laying a gravel foundation:

  1. Prepare The Site: Clear the area of any grass, roots, and debris. You want a clean, flat surface to work with.
  2. Mark The Area: Measure and mark the 10x12 area with stakes and string.
  3. Excavate: Dig down to the required depth (4 inches is standard). Make sure the base is level.
  4. Add Gravel: Pour the gravel into the excavated area. Spread it out evenly using a rake.
  5. Compact The Gravel: Use a tamper or plate compactor to compact the gravel. This step is crucial for stability.

According to our research, compacting the gravel properly can make a big difference in the longevity of your shed.
