/// Short answer
crushed stone for a patio base — the planning answer
Estimate crushed stone for a patio base by measuring the finished patio area, entering the specified compacted base depth, and calculating volume before converting to cubic yards or tons. Keep bedding sand, pavers, edge restraint, and excavation separate. The supplier's density or tons-per-yard value controls the weight conversion; a generic aggregate table should not be treated as an order guarantee.
How do you estimate crushed stone for a patio base?
Estimate crushed stone for a patio base by measuring the finished patio area, entering the specified compacted base depth, and calculating volume before converting to cubic yards or tons. Keep bedding sand, pavers, edge restraint, and excavation separate. The supplier's density or tons-per-yard value controls the weight conversion; a generic aggregate table should not be treated as an order guarantee.
Crushed-stone volume = patio area × compacted base depth. Weight = volume × supplier bulk density, using the supplier's stated unit basis.

Run the stone calculator
Use the stone calculator to combine separate rectangular or circular areas into a transparent bulk volume. Weight remains optional until you enter the selected stone's supplier density, preventing one material from standing in for another. Review each area's depth, add a job-specific allowance, and use the resulting cubic yards when discussing delivery.

What should you measure first?
Measure the patio surface in sections and record openings, curves, borders, and grade changes. Document whether the depth is loose placement or finished compacted thickness.
- Measure patio area and subtract openings.
- Record the specified compacted depth and layer name.
- Ask for the exact product density, sale unit, and delivery minimum.
What should you verify before ordering?
Base depth, drainage, compaction, subgrade, and edge restraint are project decisions. Verify the pavement assembly before using the estimate for ordering.
- Compare yards and tons with the supplier's conversion.
- Keep bedding sand and joint sand separate.
- Confirm truck access and stockpile location.

/// Common questions
Crushed Stone Patio Base: Calculate Cubic Yards and Tons FAQ
How deep should a crushed-stone patio base be?
Use the depth specified for the site, use, soil, drainage, and pavement assembly. The calculator does not choose a universal base depth.
Should patio base stone be ordered by ton or yard?
Use the supplier's normal unit after confirming its product-specific density or tons-per-yard conversion and truck capacity.
Is crushed stone the same as bedding sand?
No. They are separate layers with different materials, depths, and installation roles. Estimate each as its own line.
