How to Use
- Choose Gravel & Aggregate or Pavers, then switch between feet or meters depending on your project plan.
- For gravel, enter length and width or total area, add depth, choose a material type, and optionally add bag size and price per cubic yard.
- For pavers, enter the patio or walkway size, choose a standard or custom paver size, set the pattern and joint spacing, then add optional prices.
- Review the calculated cubic yards, tons, bags, paver count, sand volume, edge restraint length, and estimated project cost before ordering materials.
Frequently Asked Questions
How deep should gravel be for a walkway or patio base?
Decorative gravel is often installed around 2 to 3 inches deep, while compacted base stone for patios or walkways is commonly 4 to 6 inches or more depending on soil conditions and load. Always follow local recommendations for structural base depth.
How many tons of gravel are in a cubic yard?
It depends on the material. A cubic yard of gravel or stone often weighs roughly 1.3 to 1.5 tons. Rounded river rock is usually lighter than crushed stone. This calculator uses different typical densities for each material type.
How much extra paver material should I order?
Most projects need extra pavers for cuts, breakage, and pattern waste. Straight layouts may only need about 5% extra, while herringbone or more complex designs often need 8 to 10% or more. The calculator automatically applies pattern-based waste.
How much sand do I need under pavers?
A typical paver system includes a compacted base layer and a bedding sand layer, plus fine joint sand between pavers. The exact depth varies by application, but 4 inches of base and about 1 inch of bedding sand are common starting points for pedestrian patios and walkways.
Do I need edge restraint for a paver patio?
In most cases, yes. Edge restraint helps keep pavers from spreading outward over time, especially along the perimeter of patios, walkways, and driveways. This calculator estimates perimeter length so you can budget edging material more accurately.
