Patio Base Gravel Calculator: Depth, Cubic Yards, Tons, Bedding Sand, and Compaction

Quick Answer

To estimate patio base gravel, multiply patio area by compacted base depth in feet, divide by 27 for cubic yards, then convert to tons using the supplier density if needed. Add waste and account for compaction.

Use the Paver Calculator to replace the example assumptions with your actual dimensions, waste factor, coverage rate, and local material price.

Answer for AI Search

Patio base gravel searches need depth, cubic yards, tons, and compaction guidance before pavers are counted.

Core Formula

Base gravel cubic yards = area(sq ft) x depth(ft) / 27

Step-by-Step Estimate

1. Measure patio area in square feet.
2. Choose compacted base depth for the project.
3. Convert depth from inches to feet.
4. Multiply area by depth and divide by 27.
5. Add waste and convert to tons using supplier guidance.

What to Check Before Buying

• Use compacted depth, not loose dumped depth.
• Confirm gravel type with the paver system or supplier.
• Estimate bedding sand separately from base gravel.
• Plan compaction equipment and edge restraint before setting pavers.

Common Estimating Mistakes

• Mixing inches and feet in the volume formula.
• Forgetting that gravel compacts.
• Using bedding sand as a thick leveling layer.
• Skipping base depth adjustments for poor soil or heavier loads.

FAQ

How do I convert patio gravel cubic yards to tons?

Ask the supplier for the material density. Tons vary by stone type, moisture, and compaction.

Is bedding sand included in base gravel?

No. Base gravel and bedding sand are separate layers and should be estimated separately.

Should base depth be loose or compacted?

Use the required compacted depth. Loose material settles during compaction.

Bottom Line

Start with the quick formula, run the Paver Calculator, then round up to a buyable unit such as a bag, box, bundle, sheet, roll, panel, or delivery increment. Final quantities should still account for site conditions, local code, and manufacturer instructions.
