- Typical use
- Side-yard patios and trailer pads are the usual jobs.
- Thickness
- 4 inches for foot traffic and light trailers; go thicker if a loaded trailer will stand on it for long periods.
- Planning note
- Put control joints every few feet along the long side; long, narrow slabs crack across their width if you skip them.
What a 10x20 slab usually is
At 200 square feet, a 10x20 pad fits a narrow side-yard patio, a trailer spot or a covered walkway. It's long and thin, so the crew spends more time on forms than on the pour itself.
10x20 concrete slab cost breakdown
The line items above show where the money goes: concrete, 3.5 tons of gravel, 200 sq ft of wire mesh, forms along 60 linear ft and finishing labor. Labor is priced from cement-mason wages, so it moves the most by region.
Delivery for a 200 sq ft pour
The order comes to 2.59 yd³ with waste, which fits in 1 truck. Plan how the chute or a wheelbarrow will reach the far end before the truck arrives.
How to use this number
Use it to budget and to test the bids you get, not as a contract price. Contractors quote after seeing grade, access and what needs removing.
DIY vs pro for this 10x20 pour
Materials alone come to $990, about 46% of the $2,166 midpoint contractor price. The difference is $1,176 of labor, equipment, delivery and contractor overhead across 9 line items. At 2.59 yd³ the pour is under the short-load threshold, so bagged mix or a shared truck avoids a delivery fee.

Frequently asked questions
Can I park a car on a 10x20 slab?
A compact car fits, but a 4-inch patio slab isn't priced as a driveway. For regular parking, use the driveway calculator, which adds thickness and rebar.
How many cubic yards is a 10x20 slab?
2.47 yd³ at 4 inches before waste. The calculator adds a waste margin and shows the ordered amount.
Is a 10x20 slab a good DIY job?
It's at the edge. 123 bags is a long day of mixing, so many owners order a small truck and hire one finisher for the surface.
What finish should a 10x20 patio have?
Broom finish is the default because it grips when wet. Stamped or exposed-aggregate finishes cost more; switch the finish in the calculator to see by how much.
