Paver Sand Calculator

The Paver Sand Calculator estimates bedding sand volume and weight for paver patios, walkways, and parking areas. Enter paved area and sand depth, choose sharp or polymeric sand density, and get cubic feet, cubic yards, pounds, and optional material cost instantly.

Sand volume formula

Bedding sand volume is area times depth:

$$\text{Volume} = \text{Area} \times \text{Depth} \times (1 + \text{Waste\%})$$

$$\text{Weight} = \text{Volume (ft}^3\text{)} \times \text{Density (lb/ft}^3\text{)}$$

A typical 1-inch sand bed under pavers uses about 0.083 ft of depth. Sharp sand for screeding is commonly near 100 lb/ft³. Polymeric sand used in joints has a similar but slightly lower bulk density.

Planning a paver base

Bedding sand sits on a compacted gravel base and supports paver alignment. After estimating sand, use our Paver Calculator for paver count and the Gravel Calculator for aggregate below the sand layer. Buy slightly more sand than calculated to fill gaps after compaction.

Frequently Asked Questions

How much sand do I need for pavers?

Multiply patio area by sand depth. Example: 161.5 ft² with a 1-inch (1/12 ft) bed needs about 13.5 ft³ of sand before waste allowance.

What depth of sand should I use under pavers?

Most residential paver projects use a 1-inch bedding layer after the gravel base is compacted. Thicker sand can shift and cause uneven pavers.

What is the best sand for paver bedding?

Sharp, coarse sand is preferred for the screed layer because it compacts evenly. Polymeric sand is better for filling joints between pavers after installation.

How do I convert sand volume to weight?

Multiply cubic feet by bulk density in lb/ft³. At 100 lb/ft³, 13.5 ft³ of sand weighs about 1,350 lb or 0.68 tons.

Should I order extra sand?

Yes. Compaction and screeding waste typically justify a 10% extra allowance. Leftover sand can fill joints or be saved for small repairs.
