How this calculation works
- Area is length × width, or a total you already added up from rectangles.
- Pavers: order area includes cut waste. Bedding sand and base stone are separate volumes from the depths you enter.
- Concrete or stamped: volume uses slab thickness the same way the concrete calculator does. Stamped only changes the $/sq ft band.
- Gravel: volume from depth, same math as the gravel calculator. Use that tool if you need tons from a quarry density.
area = L × W; pavers = area × (1+waste%); yd³ = area × (in/12) / 27 × (1+waste%); range = area × $/sq ft
What to do next
- Ask whether the bid includes excavation, fabric, edge restraint, and haul-off—not only the surface you see.
- Slope the pad away from the house. This page does not design drainage.
- For a raised wood or composite platform, use the deck calculator instead.
FAQ
- Is this the same as the concrete calculator?
- No. The concrete calculator is yards and bags for any slab. This page is a patio planning range plus the takeoff for pavers, a sitting slab, stamped finish, or gravel. Use both if you are pouring concrete and also want a ready-mix ticket.
- Does the square-foot price include digging and base?
- Some crews bundle excavation and base into the $/sq ft; others line-item them. The default bands are installed-project envelopes, not a soils report. If your quote is surface only, drop the unit prices or add demo as a separate check.
- How much extra paver should I buy?
- Rectangles often need about 5–8%. Diagonals, circles, and mixed sizes run 10–15%. Leftover from the same lot is cheaper than a second dye lot later. Edit the waste field to match the pattern on the drawing.
- Patio or deck?
- A patio sits on grade (pavers, slab, or gravel). A deck is a framed structure with footings and usually a rail. If you need air under the walking surface, use the deck cost calculator.
