How to use the paver sand calculator calculator
- 1
Measure the paver area
Measure the length and width of the area you are paving, or enter a known square footage. For an L shape or curve, split it into sections.
- 2
Enter the specified depth
Enter the sand thickness your paver manufacturer, project plan, or contractor specifies, in the depth unit you choose.
- 3
Add options if needed
Add a waste allowance for cuts and uneven ground, a bag volume to see bags, and your own prices to estimate cost.
- 4
Review the result
Read the cubic yards, cubic feet, and bag count, and confirm the amount and material with your supplier before ordering.
Formula
Cubic yards = square feet x depth (in) / 324
Multiply the paved area by the specified sand thickness, then convert to cubic yards by dividing square feet times depth in inches by 324. For bags, divide the cubic feet needed by the bag volume and round up.
Worked example
A patio measures 16 feet by 12 feet and the project specifies a 1 inch sand bedding layer.
- 1Find the area: 16 x 12 = 192 square feet.
- 2Apply the formula: 192 x 1 / 324 = 0.59 cubic yards.
- 3In cubic feet that is 192 x (1 / 12) = 16 cubic feet.
- 4With 0.5 cubic foot bags: 16 / 0.5 = 32 bags.
The patio bedding needs about 0.59 cubic yards, or roughly 16 cubic feet of sand.
Worked examples
Walkway in two sections
A 3 by 20 foot walkway and a 3 by 8 foot landing, both at a 1 inch bedding depth.
- 1Walkway: 3 x 20 = 60 square feet.
- 2Landing: 3 x 8 = 24 square feet.
- 3Total area = 84 square feet.
- 484 x 1 / 324 = 0.26 cubic yards.
The walkway and landing together need about 0.26 cubic yards.
Adding a waste allowance
The 192 square foot patio above, with a 10 percent allowance for cuts and settling.
- 1Base volume: 0.59 cubic yards.
- 2Apply 10 percent: 0.59 x 1.10 = 0.65 cubic yards.
- 3Round up at the ordering stage, not before.
With a 10 percent allowance the patio needs about 0.65 cubic yards.
How to measure a paver area
Measure the length and width of the surface you plan to pave and multiply them for the area, or enter a known square footage directly. For an L shape, a curve, or a border, split the layout into rectangles, triangles, and circles, add a section for each, and let the calculator combine them.
Measure the area you are actually bedding, not the pallet of pavers, and keep every measurement in the same units. If you are also planning a base layer under the bedding sand, calculate that separately with the depth your plan specifies.
Why paver sand volume depends on area and depth
Sand is a volume, so the amount you need scales with both how much area you cover and how thick the layer is. Doubling the area doubles the sand, and doubling the depth doubles it again. That is why the same patio can need very different amounts depending on the specified thickness.
Because the relationship is area times depth, small depth changes matter. Entering the exact thickness from your plan, rather than rounding it, keeps the estimate honest. To see the underlying volume math, review how to calculate cubic yards and what a cubic yard is.
Base layer versus bedding layer
Many paver installations involve two different layers: a compacted base beneath, often a crushed stone product, and a thinner bedding layer of sand that the pavers rest on. They are separate materials with separate thicknesses, so they need separate estimates. This tool sizes the sand bedding layer at the depth you enter; it does not size the base.
If your project also needs a base layer, calculate that on its own using the thickness your plan specifies. Stone base materials are estimated the same way, area times depth, on the gravel calculator. Keeping the two estimates apart avoids ordering the wrong amount of either.
Bagged and bulk planning
Small paver projects are often handled with bagged sand, while larger areas may be easier by bulk delivery. Enter a bag volume to convert the result into an exact and a whole-bag count, and add your own prices to compare. The calculator never assumes a bag size or a price.
For a broader volume tool that also handles borders, circles, and weight, use the sand calculator. To plan pricing in more detail, see the sand cost calculator.
Common mistakes
Watch out for these when estimating paver sand:
- Using a depth you assumed instead of the one your project specifies
- Measuring the pavers rather than the area being bedded
- Ignoring cuts and waste on a complex layout
- Confusing the bedding layer with a separate base layer
- Rounding measurements early instead of at the final order step
Waste and cut-area variation
Curved edges, cut pavers, and slightly uneven ground all change how much sand a real installation uses. A modest waste allowance covers that variation without overbuying. Set the percentage yourself based on how complex the layout is.
As with any bulk order, keep the unrounded figure while planning and round up only when you place the order, then confirm the quantity and any minimum order with your supplier.
Paver Area and Depth to Sand Cubic Yards
Cubic yards for each area and specified depth. Read your area on the left and the depth your project calls for across the top. Every value is square feet times depth in inches divided by 324.
| Area | 1 in | 1.5 in | 2 in | 3 in |
|---|---|---|---|---|
| 50 sq ft | 0.154 | 0.231 | 0.309 | 0.463 |
| 100 sq ft | 0.309 | 0.463 | 0.617 | 0.926 |
| 150 sq ft | 0.463 | 0.694 | 0.926 | 1.39 |
| 200 sq ft | 0.617 | 0.926 | 1.23 | 1.85 |
| 300 sq ft | 0.926 | 1.39 | 1.85 | 2.78 |
| 400 sq ft | 1.23 | 1.85 | 2.47 | 3.7 |
| 600 sq ft | 1.85 | 2.78 | 3.7 | 5.56 |
| 800 sq ft | 2.47 | 3.7 | 4.94 | 7.41 |
How Much Area One Cubic Yard of Paver Sand Covers
Square feet that one cubic yard covers at each depth, from 324 divided by the depth in inches.

Frequently asked questions
- How much paver sand do I need?
- Measure the paved area, multiply by the sand thickness your project specifies, and divide square feet times depth in inches by 324 for cubic yards. Enter a bag size to see the bag count.
- What depth of paver sand should I use?
- There is no single universal bedding depth. Use the thickness specified by your paver manufacturer, project plan, contractor, and local requirements, and enter that value into the calculator.
- Is bedding sand the same as joint sand?
- They serve different purposes in an installation and can be different products. This calculator estimates the volume of a sand layer at the depth you enter; follow your project documents for which materials to use and where.
- How do I estimate paver sand for an L-shaped patio?
- Split the L into rectangles, calculate each on the sand calculator as a separate section, and add them. This paver tool works from a single area or a known square footage.
- How many bags of paver sand are in a cubic yard?
- Divide 27 by the cubic feet on the bag. For 0.5 cubic foot bags that is 54 bags per cubic yard. Always confirm the volume printed on your bag.
- Should I add extra for cuts and waste?
- A small waste allowance helps with cut pavers, curved edges, and uneven ground. Choose a percentage that matches how complex your layout is, then round up when ordering.
Paver sand volume uses the exact factors of 27 cubic feet per cubic yard and 324 square feet per cubic yard inch. Depth is never assumed; you enter the thickness your project specifies. Bag counts round up, and cost uses only prices you enter. See the YardCalc calculation methodology.
