Planning a Concrete Patio: Size, Drainage, and Finish

Start with how you will use it

Arrange the furniture before you finalize dimensions—at least on paper or with chalk in the yard. A dining set, a grill station, seating around a fire pit, and walkways between zones each need room, plus space to pull out chairs and walk behind them. Most regrets about patio size are about too little room, not too much.

Think about future plans at the same time. A pergola, outdoor kitchen, or hot tub added later is far easier when the slab was planned with it in mind.

Elevation and drainage

The patio surface needs to sit at the right height relative to door thresholds and the surrounding yard, and it must shed water away from the house. Downspouts, roof valleys, and low spots in the yard all influence the layout. Getting drainage right is the difference between a patio that lasts and one that undermines itself or floods the back door.

Choosing a finish

A broom finish is practical, slip-resistant, and budget-friendly. Stamped patterns, color, and decorative borders add character and maintenance. Around pools or in shaded areas that stay damp, traction should weigh heavily in the decision. The finish should also complement the home's brick, stone, and roof tones.

Working around the existing yard

Fences, gates, irrigation lines, trees, and utility easements all shape what is buildable. Access for equipment and concrete delivery should be part of the early conversation—especially in newer subdivisions with narrow side yards.
