How much sand do I need?
Measure the coverage area, enter the planned sand depth in inches, and convert the volume to cubic yards. A 200 sq ft area at 2 inches deep is about 1.23 cubic yards before waste.
Choose the right sand type
Leveling sand, paver sand, mason sand, arena sand, and fill sand are not always interchangeable. Confirm the material type before buying.
Sand volume vs tonnage
Sand may be sold by cubic yard, ton, or bag. Moisture and density affect tonnage, so use supplier density for weight-based orders.
Sand 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 |
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
cubic yards = (area * (depth / 12) / 27) * (1 + wastePercent / 100)
Assumptions
- Depth is entered in inches.
- The estimate assumes an even layer over the measured area.
- Compaction, settling, edging, slopes, and supplier sell units can change final ordering.
Example
Estimated sand base needed (cubic yards): 1.63 cubic yards
How to calculate sand base cubic yards
- Measure the target coverage area in square feet.
- Enter the planned finished depth in inches.
- Convert depth to feet, multiply by area, then divide cubic feet by 27 to get cubic yards.
- Add waste for uneven grade, compaction, spreading loss, or ordering increments.
- Confirm supplier units before buying, because bulk material may be sold by cubic yard, ton, or bag.
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
What is the example sand base cubic-yard result?
Use area, installed depth, cubic-foot to cubic-yard conversion, and waste, then calculate the planning result. In the default example, the result is 1.63 cubic yards.
How do I calculate sand yards?
Use cubic yards = area x (depth inches / 12) / 27, then add waste if needed.
How many square feet does 1 yard of sand cover?
One cubic yard covers about 324 sq ft at 1 inch deep, 162 sq ft at 2 inches, or 108 sq ft at 3 inches before waste.
Does moisture change sand weight?
Yes. Moisture can change sand weight and density, which matters when ordering by the ton.
Should paver sand and base rock be calculated together?
No. Calculate each layer separately because base rock and bedding sand use different depths and materials.
