How Much Gravel for a Patio Base?
Estimate gravel for a patio base by planning footprint, depth, compaction, edging, and drainage.
6 min read
Start with the patio footprint
Measure the finished patio length and width. If the base extends beyond the finished surface, include that extra footprint in the gravel estimate.
Choose a base depth
A patio base depth depends on soil, climate, drainage, and surface material. Pavers, concrete, and compacted gravel patios can have different needs.
Plan for compaction
Loose gravel settles when compacted, so the delivered amount may need to account for compaction and uneven subgrade.
Solve drainage early
A good patio base should move water away from structures. Slope, edge restraint, fabric, and outlet paths matter before ordering material.
Planning checklist
Before you make the final plan
- Confirm the project footprint, site access, and any local rules before buying materials.
- Estimate the core materials first, then add a buffer for hardware, delivery, tools, and waste.
- Check foundation, drainage, durability, and maintenance needs before choosing a final plan.
- Use calculator results as a starting budget, then compare with local material prices.
