AGGREGATE VOLUME
Gravel calculator
Convert a measured area and depth into gravel volume and bag count. Shows cubic yards, the waste allowance applied, and the formula used to get there. This is an estimated requirement—not a purchase, safety, engineering or code-compliance instruction.
Build your estimate
Choose a unit system. Switching units converts the values already entered.
Estimated requirement
Enter measurements and calculate.
- How it was calculated
- Your formula will appear here.
- Assumptions
- Waste and package assumptions will appear here.
- What may change it
- Density, moisture, compaction and supplier delivery increments vary. Confirm whether a supplier quotes loose, compacted, wet or dry material.
Worked example
A 200 ft² area at 3 in depth is about 1.85 yd³ before waste.
Check the product label and supplier before ordering. Measured conditions, layout, cuts, compaction, site preparation and local requirements may change your actual requirement.
