How much paver base do I need?
Measure the patio, walkway, pad, or paver area and enter the base depth in inches. A 240 sq ft area at 4 inches deep is about 2.96 cubic yards before waste.
Base layer vs leveling sand
Paver base and leveling sand are separate layers. Estimate compacted base material separately from the thinner bedding or leveling sand layer.
Compaction changes the order
Base rock is usually compacted in lifts. Loose delivered material, compacted depth, and supplier units may not match exactly, so keep waste visible.
Paver base example estimates
Examples are before waste. Keep base material and leveling sand as separate estimates.
| Project example | Area and base depth | Cubic yards |
|---|---|---|
| Small walkway | 120 sq ft at 4 in | 1.48 cu yd |
| Patio | 240 sq ft at 4 in | 2.96 cu yd |
| Large patio | 400 sq ft at 4 in | 4.94 cu yd |
| Thicker base area | 240 sq ft at 6 in | 4.44 cu yd |
Paver base coverage by depth
Coverage assumes 1 cubic yard, which is 27 cubic feet. Waste, compaction, settling, and irregular grade are not included.
| Depth | Coverage from 1 cu yd | Coverage from 2 cu yd |
|---|---|---|
| 1 in | 324 sq ft | 648 sq ft |
| 2 in | 162 sq ft | 324 sq ft |
| 3 in | 108 sq ft | 216 sq ft |
| 4 in | 81 sq ft | 162 sq ft |
| 6 in | 54 sq ft | 108 sq ft |
| 12 in | 27 sq ft | 54 sq ft |
Common density planning values
Use supplier-provided density for final tonnage. These broad values are planning placeholders, not product specifications.
| Material | Broad planning density | Notes |
|---|---|---|
| Gravel / crushed stone | 2,600-3,000 lb/cu yd | Varies by gradation, moisture, and compaction. |
| Sand | 2,400-3,000 lb/cu yd | Moisture can noticeably change weight. |
| Topsoil / dirt | 1,800-2,600 lb/cu yd | Moisture and organic matter change density. |
| Mulch | 400-1,000 lb/cu yd | Usually ordered by volume, not weight. |
| Compost | 800-1,500 lb/cu yd | Depends on moisture and material mix. |
Before you calculate
- Measure the area to be covered, then choose the compacted depth you actually need.
- Calculate driveways, paths, drains, and base layers separately when depths differ.
- Use density inputs only when converting volume into tons or weight.
Common mistakes
- Ordering by tons without checking the supplier's density assumption.
- Forgetting compaction for base layers.
- Combining decorative top rock and structural base rock into one estimate.
Formula
cost = ((area * (depth / 12) / 27) * (1 + wastePercent / 100) * densityPerCubicYard / 2000) * pricePerTon
Assumptions
- Depth is entered in inches.
- Density and price per ton vary by supplier, moisture, screening size, and compaction.
- Delivery, grading, fabric, base prep, disposal, and labor are separate.
Example
Estimated paver base cost: 214 USD
How to estimate paver base cost
- Measure project area and planned depth, then estimate material volume.
- Enter supplier density so the calculator can convert volume into tons.
- Enter price per ton and include waste or delivery buffer if applicable.
- Multiply estimated tons by the price per ton to get a planning cost.
- Confirm local price, delivery minimums, moisture, compaction, and tax or fees with the supplier.
Before you buy materials
- Ask whether the supplier sells by cubic yard, ton, scoop, or bag.
- For compacted base, plan for placement and compaction rather than loose depth alone.
FAQ
How do I estimate paver base cost?
Estimate paver base cost by using the measured quantity as a cost input, then multiplying by material price, labor or unit price, delivery, and waste where relevant. The default example returns 214 USD. Quantity detail: Use cubic yards = area x (base depth inches / 12) / 27, then add waste. For a cost estimate, use that quantity as the buying amount, then multiply by unit price and add labor, delivery, prep, waste, and local charges where relevant.
Is paver base the same as leveling sand?
No. Base material is the structural layer below the pavers. Leveling sand is a separate, thinner bedding layer.
Should I include compaction?
Yes. Compacted base layers can require more loose material than a simple finished-depth calculation.
Can I use this for a driveway paver base?
Use the calculator for quantity planning, but verify required depth and base specification for the actual load and site conditions. For a cost estimate, use that quantity as the buying amount, then multiply by unit price and add labor, delivery, prep, waste, and local charges where relevant.
