What is a Paver Sand?
A Paver Sand Calculator estimates how much bedding sand you need to install pavers correctly, converting your project's surface area and desired sand depth into a purchasable volume (cubic yards) and weight (tons). Bedding sand is the thin, screeded layer of coarse sand that sits on top of a compacted gravel base and beneath the pavers themselves — it lets each paver settle into a level, even surface rather than resting directly on uneven stone or soil.
Getting this quantity right matters because both under-ordering and over-ordering create real costs. Running short mid-project means a delivery delay or an extra trip to the supplier, while over-ordering ties up budget in material you don't need. This calculator removes the guesswork by applying the same volume-to-weight math a contractor would use, so you can order the right amount whether your supplier sells sand by the cubic yard or by the ton.
This tool works alongside other material estimators for the same job — pair it with the Gravel Calculator for the structural base layer beneath the sand, or the Concrete Calculator if you're comparing a poured slab alternative.
How to use this Paver Sand calculator
- Measure the total area of your paver installation in square feet and enter it in the Paver Area field (default 200 sq ft, adjustable from 5 to 5,000).
- Decide on your bedding sand depth — 1 inch is standard for most walkways and patios — and set it using the Sand Bedding Depth slider (0.5 to 4 inches).
- Review the Sand Needed result, shown in cubic yards, which updates instantly as you adjust either input.
- Check the Sand Weight result in tons if your supplier sells or delivers sand by weight rather than volume.
- Adjust the depth slider to compare scenarios — for example, see how much more sand a 1.5-inch bed requires versus a 1-inch bed for the same area.
- Use the final cubic yard or ton figure to place your material order, rounding up slightly to account for an uneven base or minor spillage during installation.
Formula & Methodology
The calculator converts area and depth into volume, then volume into weight, using standard construction unit conversions: Volume (cubic feet) = Area (sq ft) × [Depth (in) ÷ 12] Volume (cubic yards) = Volume (cubic feet) ÷ 27 Weight (tons) = Volume (cubic yards) × 1.35 Worked example: For a 200 sq ft patio with a 1-inch sand bed: - Volume (cubic feet) = 200 × (1 ÷ 12) = 16.67 cu ft - Volume (cubic yards) = 16.67 ÷ 27 = 0.62 cu yd - Weight (tons) = 0.62 × 1.35 = 0.83 tons The 1.35 tons-per-cubic-yard figure is an industry-standard average density for compacted concrete/paver sand; actual density can vary slightly by moisture content and sand type, so suppliers may round order quantities up.
Frequently Asked Questions
Most paver installations use a bedding sand layer between 1 and 1.5 inches deep, spread evenly across the compacted base before the pavers are set. The exact volume depends on your paver area and chosen depth — the Paver Sand Calculator converts that area and depth into cubic yards and tons automatically. For larger patios or driveways, always add a small buffer on top of the calculated amount to cover an uneven base.
The formula converts your paver area and sand depth into a volume, then into weight. First, multiply the area in square feet by the depth in inches divided by 12 to get cubic feet, then divide by 27 to get cubic yards. Finally, multiply cubic yards by roughly 1.35 tons per cubic yard, the typical density of compacted paver sand, to estimate weight.
Coarse, washed concrete sand (sometimes labeled paver base sand or bedding sand) is standard because it compacts well and drains water away from the paver surface. Fine masonry sand or beach sand should be avoided since it does not compact as reliably and can wash out over time. Polymeric sand is a separate product used to fill the joints between pavers, not the bedding layer underneath them.
Gravel, usually crushed stone, forms the structural base layer that carries the load and provides drainage, typically 4 to 6 inches deep depending on soil and traffic. Sand is a thin leveling layer, generally 1 inch, spread on top of the compacted gravel to create a smooth, even surface for setting pavers. You need both materials for a durable installation — use the [Gravel Calculator](/gravel-calculator/) to estimate the base layer separately.
No, they serve different purposes and should not be swapped. Bedding sand sits below the pavers and provides a level foundation, while polymeric sand is swept into the joints between pavers after installation and hardens to lock them in place and resist weeds. Using bedding sand in the joints will not bind the pavers together.
A standard walkway or patio typically uses a 1-inch bedding sand layer over a compacted gravel base. Driveways carrying vehicle weight generally use the same 1-inch sand layer but require a thicker gravel base beneath it, often 6 to 8 inches, to handle the additional load. The sand depth itself rarely changes — what changes is the base layer thickness.
Enter your paver installation area in square feet using the Paver Area field, then set your intended sand depth in inches with the Sand Bedding Depth field. The calculator instantly returns the volume in cubic yards and the estimated weight in tons. Adjust either field and the results update immediately, making it easy to compare different depths.
Yes, if you plan to buy bagged sand instead of bulk. A standard 50-pound bag covers roughly 0.5 cubic feet, so divide your total cubic feet requirement by 0.5 to estimate the number of bags needed. For larger projects over a few hundred square feet, ordering bulk sand by the cubic yard or ton from a landscape supplier is almost always more cost-effective than bags.
Sand suppliers price and deliver material differently depending on the vendor — some sell by volume (cubic yards) and others sell by weight (tons). Showing both units means you can order correctly no matter how your local supplier quotes the material. The tonnage figure uses an average compacted sand density of about 1.35 tons per cubic yard.
The bedding sand layer is typically screeded flat, not compacted, so pavers can settle evenly into it as they are placed and vibrated with a plate compactor afterward. Compacting the sand before placing pavers can create an overly dense, uneven surface that is harder to screed accurately. Compaction happens after the pavers are down, locking sand into the joints and the base together.
Too little sand means pavers sit unevenly on the gravel base and can rock or crack under load. Too much sand creates a soft, unstable layer that allows pavers to sink or shift over time as the excess sand settles or washes out. Sticking close to the standard 1-inch depth, as used in this calculator's default, gives the most reliable results for most residential projects.
