Estimate paver bedding sand volume and bag count from project area, sand depth, bag yield and waste. Plan the leveling layer below pavers before buying.
Enter your measurements and material details.
Use the bedding-layer thickness specified for the paver system; excessively thick loose sand can create installation problems.
Paver bedding sand is a thin leveling layer placed above the compacted base. Because the layer is shallow, small depth changes can noticeably affect bag count over a large patio. This calculator converts the planned layer into cubic feet, cubic yards and whole bags.
Use the finished paver area and the intended uncompacted or screeded sand thickness from the installation specification. Enter the cubic-foot yield printed on the bag you plan to buy when using bagged material.
Enter the specified bedding depth and project area; the calculator converts it to volume.
No. Bedding sand goes below pavers, while polymeric sand fills joints.
Yes. Use the cubic-yard result rather than bag count.
Use the volume or coverage printed on the specific bag.
Follow the paver system instructions; this calculator only estimates quantity.
Using the example inputs shown in the calculator — Project length (ft) = 20, Project width (ft) = 15, Bedding sand depth (in) = 1, Bag yield (cu ft) = 0.5, Waste allowance (%) = 10 — the result is 27.5 cubic ft. This demonstrates the formula with a complete set of numbers rather than a hidden assumption.
The result breakdown also shows Cubic yards: 1.02 yd³; Bags: 56. Replace the example values with field measurements and the exact product coverage, yield or package size you plan to buy.
For this paver sand calculator, the inputs with the greatest practical effect are project length, project width and bedding sand depth. Recalculate when any of those change; do not reuse a result from a different room, run, layer depth or product specification.
These quick examples use the same calculator formula and the assumptions stated in each row. They are useful for scale checks; use your own measurements for ordering.
| Example | Calculated result |
|---|---|
| 100 sq ft patio at 1 in bedding depth | 9.2 cubic ft |
| 200 sq ft patio at 1 in bedding depth | 18.3 cubic ft |
| 400 sq ft patio at 1 in bedding depth | 36.7 cubic ft |
A useful paver sand estimate begins with dimensions taken from the actual project. Small measurement errors can become significant when they are repeated across many boards, joints, courses, bags or rolls. Record the dimensions you used and keep net geometry separate from the purchase allowance so the result can be checked later.
