A circular paver patio is built by choosing a diameter from your headcount, marking the circle with a string from a center stake, excavating to a uniform depth, compacting a base at least 4 inches thick, and laying pavers in rings from the center out. A 14 foot circle covers about 154 square feet, which is enough for a table and a fire pit.
Most guides show the laying. The decisions that go wrong are earlier: the size, the slope and the base. I will cover those first. If you want the kit itself, circle pavers goes through how the rings work.
How big should a circular paver patio be?
Landscape architect Paul Maue's rule of thumb in This Old House's round patio guide is about 25 square feet per person, for a seat and room to move. A circle's area is pi times the radius squared, so the table is quick to work out:
| Diameter | Area | People at 25 sq ft each |
|---|---|---|
| 10 ft | 79 sq ft | about 3 |
| 12 ft | 113 sq ft | about 4 to 5 |
| 14 ft | 154 sq ft | about 6 |
| 16 ft | 201 sq ft | about 8 |
A center fire pit takes space. The 50 inch fire pit in Western Interlock's circle patio walkthrough removes roughly 14 square feet, so a 14 foot patio with that pit seats around five or six. That walkthrough builds a 12.5 foot circle plus a border ring, about 14 feet overall.
Mark the circle with a string, not by eye
The layout tool is a stake and a tape measure.
- Drive a stake at the center. Decide the position from the house door and the lines of the yard, not from the lawn's most convenient bare spot.
- Hook the tape on the stake and extend it to the radius. For a 14 foot circle, that is 7 feet.
- Walk the circle, spray-painting the line as you go.
- Paint a second line 6 to 8 inches outside it. Western Interlock advises the gravel base to extend 6 to 8 inches past the pavers for edge restraint. CMHA's guide spec sets the distance from base edge to restraint spikes equal to the base thickness, up to 10 inches, so use the wider figure if you are unsure.
Leave the stake in until you have excavated, because it holds the center for the screed and the first paver.
Set the slope before you dig
Water has to leave a round patio in one direction, and a circle has no obvious "downhill." Pick the side away from the house and any building.
ICPI Tech Spec 2 sets a minimum surface slope of 1.5%. That is about 2.5 inches across a 14 foot circle. The This Old House project uses a similar approach, with screed rails dropping 1 1/2 inches across the diameter, and Western Interlock's walkthrough drops about 2.75 inches over a 14 foot run. Near the house, the IRC (R401.3) calls for at least 2% on impervious surfaces within 10 feet of the foundation, roughly 1/4 inch per foot. Check with your local building department.
Run strings from the highest point to the lowest at the final paver surface, with extra strings every 1 to 2 feet. Everything else, the excavation depth and the base, is measured from those strings.
Dig, compact and screed for a round patio
The numbers are the same as any paver base, and the circle only changes the edge.
- Excavate 7 inches below the strings (Western Interlock): 4 inches of base, 1 inch of bedding and just over 2 inches of paver.
- Base: at least 4 inches of compacted crushed stone on well-drained soil, plus 2 to 4 inches on weak, wet or freezing ground (ICPI Tech Spec 2). Some guides use 2 inches; ICPI's figure is a minimum for patios, so I would not go below it.
- Compact in lifts, with a plate compactor, and keep the base surface flat to 3/8 inch over 10 feet (CMHA).
- Bedding sand: 1 inch, screeded and left loose, using screed rails or 1 inch metal tube.
Quantities for a 14 foot circle: the excavation is about 3.3 cubic yards of soil, and the 4 inch base is about 1.9 cubic yards, or 2.6 to 3.2 tons of crushed stone at 1.35 to 1.7 tons per cubic yard. The plate compactor is a rental item, and how much paver base do I need shows the math.
Lay the rings from the center outward
Start at the center paver, or with a pair of pavers on the center line if you are using a kit. Then work outward ring by ring, tapping each paver level with a rubber mallet. This Old House and Western Interlock both lay in this order, because the center holds the geometry for every ring after it.
You have two ways to get the curve:
- A circle kit. The pieces are trapezoids that form rings of any diameter with no cuts. Follow the pallet tag.
- Rectangular pavers. Fan them out and cut the wedge gaps at the edge. This is where how to cut pavers for curves pays for itself.
Fine, a kit costs more, and a saw costs time and dust. Rent the saw if you already own the pavers.
Edge, border and a fire pit in the middle
A contrasting border ring of lighter pavers defines the edge. Flexible plastic edging secured with 8 inch galvanized spikes works for a curve, and paver edging compares the types. Do not skip the restraint: without it the outer ring spreads and the circle goes oval.
For a fire pit, This Old House removes one ring of patio pavers and sets the fire pit's first course on the base in that space, staggering the joints in each course. The center gives you the focal point and the seating faces it. Check local rules for fire pit clearances before you build. The details are in our piece on fire pit clearance from house.
Plan the circle first and the paving falls into line
A circular paver patio is mostly planning: a diameter you can furnish, a slope that moves water off, a base at least 4 inches thick, and a center stake that stays put until the first ring is down. Get those right and the laying is the pleasant part.
FAQ
How do you lay pavers in a circle?
Mark the circle from a center stake, build the base and sand bed, then lay from the center out in rings. A circle kit needs no cuts. Rectangular pavers need wedge cuts at the edge.
What size should a circular patio be?
Plan about 25 square feet per person. A 12 foot circle (113 sq ft) suits four to five people, and a 14 foot circle (154 sq ft) around six, less the space a center fire pit takes.
How do you drain a round paver patio?
Give it a one-direction slope of at least 1.5%, falling away from the house. That is about 2.5 inches across a 14 foot circle.
Do you need edge restraint on a circular patio?
Yes. Use flexible plastic edging spiked into the base (This Old House uses 8 inch galvanized spikes), a concrete toe, or a curb. Without it the outer ring spreads.
Can you put a fire pit in a circular paver patio?
Yes. Remove one ring of patio pavers at the center and build the fire pit on the base in that space. Check local rules on clearances.
