Explanation
How gravel quantity is calculated
How the calculation works
The calculator multiplies length by width by gravel depth. Depth is converted from inches to feet. Cubic yards are cubic feet divided by 27, then tons are estimated from the selected gravel density.
Example calculation
For a 12 by 8 foot area at 4 inches deep, the estimate is 32 cubic feet, or 1.19 cubic yards. Standard gravel is about 1.66 tons.
Project planning
Turn the gravel estimate into an order plan.
After you know cubic yards and tons, choose the material type, depth, delivery setup, and base details for the actual project.
Choose the right gravel type
Compare crushed stone, pea gravel, decorative stone, and compacted base material before ordering.

Landscape fabric
May help separate gravel from soil for paths, pads, and bases.
Edging or frame material
Keeps gravel contained and improves the finished shape.
Compaction tools
A tamper or plate compactor may be needed for pads and bases.
Delivery and spreading plan
Plan the dump location, access, wheelbarrow route, and cleanup.
Before buying
- Ask suppliers whether material is sold by cubic yard or ton.
- Confirm density and minimum delivery quantities locally.
- Add a small buffer for compaction, uneven ground, and spreading loss.
FAQ
Gravel calculator questions
How do I calculate gravel volume?
Multiply length by width by depth. Convert depth from inches to feet, then divide cubic feet by 27 to get cubic yards.
How many tons are in a cubic yard of gravel?
A common planning range is about 1.4 to 1.6 tons per cubic yard, depending on gravel type and compaction.
Should I order extra gravel?
Yes, a small buffer can help account for compaction, uneven ground, and spreading loss.
Can I use this for a shed base?
Yes, it is useful for a simple shed base estimate, but confirm depth and compaction requirements for your site.
Formula and assumptions
How this estimate should be used
Planning gravel for paths, shed bases, pads, drainage areas, and simple landscaping projects.
Formula summary
- Gravel volume = length x width x depth
- Depth is converted from inches to feet before calculating cubic feet
- Cubic yards = cubic feet / 27
- Approximate tons = cubic yards x selected gravel density
Planning assumptions
- Gravel density varies by stone type, moisture, and supplier.
- Compaction and uneven ground can increase the amount needed.
- The result is a planning estimate and should be checked against supplier guidance.
