Paver Sand Calculator

Find the volume and weight of bedding sand needed for your paver installation by entering the paved area, bed depth, and sand density.

Default is a typical dry sand density; adjust as needed.

Result

0.62 cu yd

200 sq ft at 1 in deep needs about 0.62 cubic yards (0.83 tons) of bedding sand

Quick Answer

The paver sand calculator finds bedding sand volume by multiplying the paved area by the bed depth: volume = area × depth. For 100 square feet at 1 inch deep (0.0833 ft), the volume is 8.33 cubic feet. Weight equals volume multiplied by density; at 100 lb per cubic foot, that is 833 lb. This tool covers the leveling layer under pavers only, not joint or polymeric sand.

How A Paver Sand Bedding Calculator Works, Step By Step

A paver sand calculator finds the volume and weight of the bedding sand layer that goes directly beneath your pavers before they are set and compacted. Bedding sand is the leveling medium screeded to a uniform depth, typically 1 inch, that allows each paver to be tapped into a consistent plane. This tool calculates that specific layer. It does not calculate the joint sand or polymeric sand swept into the gaps between pavers after installation, which is a separate material purchased by the bag. The calculation uses the paved area and the chosen bedding depth to find a volume in cubic feet, then multiplies by density to give weight in pounds. Most suppliers sell bedding sand by the ton or cubic yard, so the result helps you match the calculator output to a supplier quote.

The Paver Sand Volume Formula Behind Every Estimate

Volume (cu ft) = Area (sq ft) × Depth (ft). Weight (lb) = Volume (cu ft) × Density (lb/cu ft). Depth in inches is converted to feet by dividing by 12 before multiplying.

  • Volume (cu ft) = Area (sq ft) × Depth (ft).
  • Weight (lb) = Volume (cu ft) × Density (lb/cu ft).
  • Depth in inches is converted to feet by dividing by 12 (1 in = 0.0833 ft).

Paver Sand Calculator Steps: Enter, Calculate, Check

Inputs

  • Paved area in square feet (length × width).
  • Bedding depth in inches (1 inch is standard for most paver projects).
  • Bulk density of coarse washed bedding sand in pounds per cubic foot (default 100 lb/cu ft).

Steps

  1. Measure the length and width of your paver area in feet and multiply to get total square footage.
  2. Enter that area in the paved area field.
  3. Enter the bedding depth in inches (leave at 1 in unless your spec differs).
  4. Adjust the density if your supplier quotes a different value; otherwise leave the default.
  5. Read the volume in cubic feet and the weight in pounds from the output.
  6. Divide cubic feet by 27 to get cubic yards if your supplier quotes by the yard.

Paver Sand Calculator In Practice: A Worked Example

100 sq ft area, 1 inch bedding depth, 100 lb/cu ft density

  1. Convert depth to feet: 1 in ÷ 12 = 0.0833 ft.
  2. Calculate volume: 100 sq ft × 0.0833 ft = 8.33 cu ft.
  3. Calculate weight: 8.33 cu ft × 100 lb/cu ft = 833 lb.

8.33 cubic feet of bedding sand, weighing approximately 833 lb (0.31 cu yd).

When A Paver Sand Calculator Gives The Right Answer

Use this calculator when planning the bedding layer for a walkway, patio, driveway, or pool deck where interlocking pavers sit on a screeded sand bed. It is most useful at the material-ordering stage, before the project starts, to get a weight or volume figure you can compare with a supplier quote. It also helps when you have a supplier price per ton and need to know how many tons to order for a given area and depth.

Assumptions

  • The area entered is the net paved footprint; irregularly shaped areas should be broken into rectangles and summed.
  • Bedding depth is the uncompacted placed depth; some compaction occurs after paver installation, but this is the standard amount to order.
  • Density default of 100 lb/cu ft represents typical coarse, washed bedding sand; fine or wet sand will differ.
  • Calculation covers bedding sand only. Joint sand and polymeric sand are separate materials not included here.

Limitations

  • Does not calculate the compacted aggregate base layer below the sand bed.
  • Does not calculate joint sand or polymeric sand for filling paver gaps.
  • Area must be entered as a single flat footprint; sloped or multi-level surfaces need to be calculated per level.
  • The density default is a typical figure; confirm with your sand supplier for their specific product.

In Practice

The most common mistake is confusing bedding sand with joint sand and trying to use this calculator for both. Bedding sand is the thick screeded layer under the pavers, roughly 1 inch deep across the whole area. Joint sand is the small amount swept into the narrow gaps between paver faces after compaction, and it is usually sold in bags rather than by the cubic yard. If you are only filling joints, you need far less material than this calculator shows. Use this tool for the under-paver layer, and check the paver manufacturer's bag coverage table for joint sand quantities.

Frequently Asked Questions About The Paver Sand Calculator

How Much Bedding Sand Do I Need Per Square Foot?

At 1 inch deep and a density of 100 lb/cu ft, you need about 8.33 lb of bedding sand per square foot. At that rate, a 10 by 10 ft patio (100 sq ft) requires roughly 833 lb, or just under half a ton. Order 5 to 10 percent extra to account for waste and uneven grading.

Is This Calculator for Bedding Sand or Joint Sand?

This calculator is for bedding sand only, the leveling layer screeded to a uniform depth before paver installation. It does not calculate the joint sand or polymeric sand swept into paver gaps after compaction. Joint sand is purchased separately, usually in bags, and the required amount depends on the paver size and joint width, not the bed depth.

What Density Should I Use for Paver Bedding Sand?

A density of 100 lb per cubic foot is a reasonable default for coarse, washed bedding sand. Actual density varies by grain size, moisture content, and mineral composition. If your sand supplier gives a specific bulk density for their product, enter that figure in the density field for a more accurate weight estimate.

How Deep Should the Bedding Sand Layer Be?

Most paver installation guides recommend 1 inch of bedding sand as the standard depth for residential patios, walkways, and driveways. Deeper layers can shift and cause surface unevenness after compaction. Some commercial or heavy-load specifications use the same 1 inch depth, relying on a thicker aggregate base below for structural support rather than a deeper sand layer.

Can I Use This Calculator for Polymeric Sand?

No. Polymeric sand is a joint-filling material used after paver installation, and the quantity needed depends on paver dimensions, joint width, and layer depth, not the overall bedded area. Use the coverage rate from the polymeric sand manufacturer's packaging for that calculation. This tool covers the screeded bedding layer only.
