Inputs
Tip: Base layers commonly run 3–6 inches depending on use.
Results
Gravel volume
3.26 yd³
88 ft³ total
FAQ
- How much extra gravel should I order? 5–10% waste is typical for uneven bases and compaction.
- Is gravel sold by weight or volume? Suppliers often sell by the ton, so confirm conversion rates.
- What depth is common for paths? Many walkways use 3–4 inches of compacted gravel.
Assumptions
- Area is rectangular length × width.
- Depth is averaged across the surface.
- Waste covers compaction and uneven subgrade.
Example
A 20 ft × 12 ft area at 4 in depth with 10% waste needs about 3.26 yd³ of gravel.
