Start with the square footage. A 12x16 patio is 192 square feet, and patio pricing is square footage times a finish rate, plus whatever the site adds. Here is the worked math at our example rates. Every figure below is an example, not a market price.
| Finish | Example rate | 12x16 (192 sq ft) |
|---|---|---|
| Standard broom | $9 / sq ft | $1,728 |
| Exposed aggregate | $13 / sq ft | $2,496 |
| Stamped | $16 / sq ft | $3,072 |
Why this shape earns its keep
A 12x16 is the smallest patio that comfortably does two things at once. The long dimension lets you put a dining set at one end and the grill at the other, so nobody eats in the smoke. That layout is most of the reason people pick this size over a 12x12.
Here is a finish detail specific to that layout: some owners run a decorative finish on the dining end and keep the grill zone plain broom, because grease and a stamped, sealed surface are a bad mix. Splitting finishes on one pour is a conversation for the contractor, but the option exists on a rectangle in a way it does not on a small square.
The add-ons that change it
- Tear-out. Old concrete out first is $4 per square foot in our example add-ons, $768 at this size.
- Site prep and grading. An example $2 per square foot, $384, if the ground needs work before forms go down.
- Sealing. Another example $2, $384, and most worthwhile over aggregate or stamped finishes.
- Access. At 192 square feet and the typical 4 inch patio thickness you need close to two and a half yards of concrete, so where the truck parks matters.
Deciding between plain and decorative? Stamped vs plain concrete walks the trade-off, and what to charge per square foot for flatwork explains how the rates themselves get built. For any other size, use the concrete patio cost calculator.
