Originally Published on January 3, 2020. Last Updated on February 29, 2024.

Suppose you have a round patio, porch, or deck. In that case, you have an opportunity to try designs and decor that don’t always work in conventional square and rectangle spaces. Since curvy outdoor settings aren’t that common, finding information on how to design and decorate them can take a little more time—but that’s where we come in. 

We rounded up all the information you need to design a dreamy discoidal backyard setting, including measuring advice, styling tips, and circular patio ideas for spaces of varying sizes and shapes.

How to Measure a Circular Outdoor Space

Graph: How to measure a circular outdoor space.

The first step is to gather as much information as possible, so start by measuring your outdoor space. You’ll want to refresh yourself on basic geometry to calculate the exact amount of square footage you have to work with in your round space.

  1. Measure the diameter of the setting (the length from one end to the other at the widest part of the circle). 
  2. Divide the diameter in half to get the radius, and find the center of your space.
  3. Next, calculate the area of your circular patio (the radius squared, then multiplied by 3.14, aka pi). 

So, if the diameter of your deck is 20 feet, your radius would be 10 feet; 10 squared is 100, and when 100 is multiplied by 3.14, you have a patio with 314 square feet of space.

20 ÷ 2 = 10

10² = 100

100 x 3.14 = 314

If you want to know the circumference (the distance around the circular space’s perimeter), multiply the radius by two to get the diameter, then multiply the product by pi. Using the dimensions listed above, the radius is 10 feet. When multiplied by 2 we get the diameter, which is 20 feet. 20 feet multiplied by 3.14 leads us to a circumference of 62.8 feet.

10 x 2 = 20

20 x 3.14 = 62.8

  PRO TIP:  
Keep these dimensions handy when shopping for outdoor furniture and large structures like gazebos or pergolas. This lets you compare measurements and ensure you’re buying appropriately sized furnishings. 

Style Tips for Circular Backyard Designs

Use our style advice to create a relaxing round outdoor space.

1. Divide Circles into Squares

If your patio is large enough, divide the circle into multiple squares where you can place zones of furniture based on how you’d like to use the space. Find the square footage of each space, and keep the numbers handy when shopping for outdoor furniture to ensure you’re not selecting pieces that are too large for each square. 

2. Pick Light Colors for an Open Feel

When selecting the main shades for your outdoor color scheme, lean on lighter hues for your decor, furniture, and backdrop. This makes your circular patio seem larger, which is extra important if you have limited square footage.

3. Decorate With Decals, Murals & Thin Decor

Adorning rounded walls, fences, and railings requires a bit of out-of-the-box thinking. 

  • Try applying decorative decals that fit the wall’s contours, or paint a large mural on your fence if you’re adept with a paintbrush. 
  • Picture frames, shelves, and planters aren’t off-limits either—we suggest choosing long and thin pieces to better fit the curved horizontal surfaces. 
  • Look for planter designs that attach to your railing’s balusters rather than the handrails, or use adjustable rail hangers that can hold hanging baskets.

4. Create a Rounded Focal Point with Furniture

Our eyes are drawn to spherical shapes, so capitalize on this concept with these furniture styling tips:

  • Place a round fire pit table in the center of your back deck and surround it with curveback Adirondack chairs for a cozy conversation space. 
  • A circular dining set atop a round area rug will do the trick in your annular alfresco area.

5. Style Furniture With Rounded Edges

If you prefer to use more angular furniture, try this compromise: Use pieces with rounded edges. You can still have the straight lines you like, but the softened edges and ends will connect the styles with the room’s rotundity. 

6. Install Curvy Lighting

Use round lights to bring a little drama to your circular patio. Teardrop pendant lamps, spiral chandeliers, winding track lighting, and other sculpted fixtures are ideal round-room illuminators.

7. Use Circular Pavers, Paving Stone Molds, or Stamped Concrete

Start any of these methods if you’re designing a round patio from the ground up. 

  • Rounded pavers: You can create all kinds of curvy designs with circular paving stones because they’re available in varying shapes. Flagstone, for example, is a popular patio material because each piece comes in its own unique shape, allowing homeowners flexibility in their designs.
  • Paving stone molds: If you like DIY projects, make your own pavers in the shape and color you want with a paving stone mold. Simply prep your space, mix up some concrete, pour it into the mold, and repeat. Most molds are reusable, so you can create winding walkways, landscaping borders, and other pretty paved projects.
  • Stamped concrete: This method involves pouring concrete into a pre-built space, then stamping it with heavy texturizing mats that mimic the shape and texture of your preferred material, e.g., wood, stone slabs, bricks, etc.

8. Remember: Less is More

Circles lack corners, so unless you have custom-built furnishings that fit the exact curvature of your walls or railings, you’ll have to limit the number of seats and tables you can use. Pushing straight-edged pieces to the sides of a round room will look off. Your best bet is to style your furniture toward the center of the space, leaving enough on all sides so guests have room to walk.

10. Fire Pit Area

20. Interlocking Lounge Space

Design your round garden Venn diagram-style. Use pavers of varying colors and shapes to denote the separate circular spaces and overlapping areas, then add the furnishings. Try benches or chairs in the outer portions, then style planters in the connected spaces. In the center, place a fountain or large sculpture to serve as a focal point.


How do you style a round patio?

Style a round patio from the center outward. Use a circular table or fire pit as the focal point and surround it with lounge seating. Dot the perimeter with round pots of flowers or encase the space with landscaping designs filled with fluffy ferns and tall arborvitae.

What is the cheapest type of patio to build?

Gravel and bark chippings are the cheapest flooring options for patios. Both are loose materials that can be spread into your preferred shape with a rake or shovel—just remember to lay down landscaping fabric and a secure border to prevent weeds and keep the materials in place.

Can you make a circular patio with square pavers?

You can certainly build a circular patio with square pavers. We highly recommend planning your layout beforehand so you know how many pavers to get and investing in an angle grinder so you can cut the material into different shapes if needed. Then, simply lay the pavers in the circle shape you want, starting in the middle and working your way out.  

What is the best size for a circular patio?

The best size for a circular patio depends on the available square footage and the area’s intended purpose. If you want a cozy breakfast nook that can house a round four-person dining set, you’ll only need a room with a 10-foot diameter. This offers enough space for everyone to pull out their chairs and walk around the table. To accommodate larger pieces and more guests (a seven-piece deep seating set, for example), plan a minimum circular space with a 15-foot diameter.
