The right outdoor rug size patio rule is the furniture footprint plus about 2 feet on each side for a dining set, or at least the front legs of every seat on the rug for a lounge group. In practice that means 5 x 7 or 5 x 8 for a bistro pair, 6 x 9 or 8 x 10 for a conversation area, and 8 x 10 or 9 x 12 for a dining table. Leave a strip of bare patio around it. (A rug that touches every edge is not a rug. It is a carpet that has lost an argument with a wall.)
Outdoor rug size patio by furniture group
The sources I opened agree on the standard sizes more than on the rules. Here is where they overlap.
| Setup | Common rug size | Source |
|---|---|---|
| Apartment balcony | 3 x 5 | Ruggable |
| Bistro set, two chairs | 4 ft round, or 5 x 7 | Custom Rugs; Ruggable |
| Small conversation set | 5 x 8 | Custom Rugs |
| Conversation area | 6 x 9 or 8 x 10 | Ruggable |
| Sectional or deep seating | 7 x 9 | Custom Rugs |
| Dining set, 4 to 6 seats | 8 x 10 or 9 x 12 | Ruggable; Custom Rugs |
| Large patio or 10-plus seats | 9 x 12 up to 11 x 14 | Ruggable; Custom Rugs |
The size ranges above come from Ruggable and Custom Rugs. Ruggable's tip for the in-between case is to take the larger size, which looks more balanced.
The dining rule: table plus 2 feet on every side
The reason for the extra rug is chairs. When someone stands and pushes back, the chair legs should still be on the rug, or the whole set rocks on the edge. Custom Rugs gives a formula of table dimension plus 24 inches, and says a 6 to 8 foot rectangular table pairs with an 8 x 10 or 9 x 12 rug. Rug & Home frames it as 50 to 55 inches larger than the table and chairs together. They are measuring different things, so the numbers do not clash: if you start from the table alone, add 24 inches a side.
Here is my own arithmetic for the most common case. A six-seat table of 36 x 72 inches plus 24 inches on every side needs a rug of at least 7 x 10 feet. Rugs come in 8 x 10, so you take that. Custom Rugs also pairs a 48 inch round table with an 8-foot rug, but its own formula adds 24 inches only once (72 inches), while the example adds it to both sides (96 inches). The example is the safer pick for a round table, because pulled-out chairs need the room.
Lounge seating: front legs on, back legs optional
Ruggable and others say to keep at least the front legs of seating on the rug, and placing all legs on it ties the group together. Rug & Home says furniture should sit on the rug with at least 25 inches of rug left on each side, while Custom Rugs puts the overhang at about 18 inches for a legs-only layout and 24 inches or more for an all-on layout. Again the figures differ, so choose by layout: all legs on gets 24 inches, front legs only gets 18.
Will the rug fit the patio you built?
This is the part the rug guides skip, because they do not know how big your patio is. Rug & Home recommends leaving 12 to 24 inches between the rug edge and the patio perimeter, and Custom Rugs wants at least 12 inches from walls or railings.
Work it through for a patio sized with our patio size for dining table rule, which gives 9 x 12 feet for a six-seat table. An 8 x 10 rug on a 9 x 12 patio leaves 6 inches on the long sides and 12 inches on the ends (my arithmetic, shown in the diagram). That is under the 12 inches the sources want. So either size the patio at 10 x 12, or go down to a 7 x 10 rug, which is the exact minimum for that table and leaves 1 foot on the long sides. It is much cheaper to change the rug than the patio. If you are still at the planning stage, the rug is a reason to add a foot to the patio now, while the base is not yet dug.
Round, square and runners
Match the rug shape to the table: round under round, rectangle under rectangle. Rug & Home recommends square or round rugs for small patios, and a 3 x 5 or a runner for tight spots. Custom Rugs uses a 4 foot round for a bistro pair and a 2 to 3 foot runner for entryways.
What the rug sits on: pavers
None of the three guides says anything about the surface underneath, and a paver patio has a few quirks. A flat patio takes any of these rugs, but a patio with sunken or rocking pavers will telegraph the problem through a thin rug. Our patio furniture on pavers guide covers wobbly tables. I could not find a source on how long a damp rug can sit before it marks pavers, so I will not give a number. The cheap precaution is to lift it every few weeks, let both sides dry, and rinse the pavers beneath. That also catches the early stages of the problems in leaf stains on pavers and cleaning moss off pavers.
Tape it out first, then buy one size up
Before you buy, mark the rug size on the patio with painter's tape or a few strips of cardboard, set the table and chairs on it, and slide a chair back as if you were standing up. If a chair leg leaves the tape, the rug is too small. If the tape is closer than 12 inches to the edge, the patio is. Between sizes, take the bigger one. A rug that is slightly too large can be pulled in; a rug that is too small just sits there looking sorry for itself.
FAQ
What size rug do I need for a patio dining table?
Add about 24 inches to each side of the table, according to Custom Rugs. A 6 to 8 foot rectangular table pairs with an 8 x 10 or 9 x 12 rug, and a 48 to 60 inch round table with an 8 x 8.

For legs-only layouts, about 18 inches of rug beyond the furniture, and 24 inches or more when all legs are on (Custom Rugs). Rug & Home recommends at least 25 inches.
