Outdoor sofa dimensions come in three layers: the overall footprint, the seat measurements, and the space around the arrangement. When you browse outdoor sofa sets, read all three together. Width and depth show where the furniture stands. Seat height and seat depth show how it feels to sit. Add your table, walking routes, and any fire feature or swivel movement, and you have a complete patio plan.
Start with how you want to spend time outside. A deep sectional for stretching out, a compact swivel set for conversation, and a fire-pit lounge for cool evenings each call for a different layout. Measure the set in the arrangement you plan to use, add its companion pieces and the routes that stay open, and you will know exactly what fits.

Read the dimension labels first
Overall width follows the longest side of a specified arrangement, and depth runs front to back. A chaise or an L-shaped return makes the overall depth much larger than that of a straight sofa, so check which orientation the diagram shows.
A "sofa piece" measurement describes one component. The same goes for a chair or chaise. When pieces connect, ask how they join before adding widths together, because overlap and connector positions affect the total. When pieces stand separately, you can place them wherever the plan works best.
Height has layers too: frame, back, cushion, and seat. A diagram that shows what each number includes lets you compare sets confidently.
Dimension | What it helps you decide | Pair it with |
Overall sofa footprint | Placement within a specific arrangement | Table size and walking routes |
Sofa piece / chair dimension | Which pieces fit a given wall or corner | Gaps between pieces |
Seat height | Comparison with seating you already like | Your own sit-and-stand test |
Seat depth | Upright versus lounging preference | Overall depth for the footprint |
Seat cushion thickness | How plush the seat will feel | Seat height, to see how they relate |
Chaise dimensions | How far the set projects into the patio | Space to walk past its end |
Moving-part envelope | Room for swiveling | Distance to tables and walls |
Match seat fit to the people who use it
A sofa that fits the patio should also feel right to sit on. Compare seat height and depth with furniture you already enjoy, and remember that cushions compress. Deep seats suit lounging with feet up; a shallower seat suits upright conversation.
Think about everyone who will use the set. Sit down, settle in, and stand up again, and see whether the posture feels easy. If support or mobility needs matter, individual advice from a professional is worth having.
Table height matters just as much. A low coffee table is the natural companion for lounge seating, and a matching table keeps drinks within easy reach.
The deep sectional: room to stretch out
The Resaro four-piece teak modular outdoor sectional in white lists an overall arrangement of 4001 mm wide by 1750 mm deep by 691 mm high. In feet, that is roughly 13 feet by 5.7 feet. The seat height is 432 mm, the sofa seat depth is 737 mm, the chaise seat depth is 1499 mm, and the seat cushion thickness is 381 mm.
Best for: a spacious patio or backyard deck where the sectional is the star. Picture weekend afternoons with the whole family: two people stretched along the chaise with a book, others sitting upright on the sofa modules, and a low table in the middle for snacks and drinks. The 381 mm cushions give the plush, sink-in feel that makes it a favorite for long movie nights outdoors.
The standard sofa module is 1001 mm by 919 mm, and the chaise is 1001 mm by 1750 mm. Both are 691 mm high. The chaise depth equals the overall depth, so the chaise is the part that reaches farthest into the patio. Put its end where it has the most room, and you gain the most generous lounging spot in the layout.
A deep sectional also welcomes a clear entrance. Mark the chaise end, the central table, and the route from the house first, then fit the rest of the furniture around them. That way the corner seat is as easy to reach as the end seat.
The fire-pit lounge: evenings that start at sunset
The Tevara modular outdoor sofa set with a propane fire pit lists a sofa piece of 2451 mm wide by 701 mm deep by 820 mm high, with a 406 mm seat height. That is about 8 feet of seating per piece. The 820 mm height gives the set more back support than the other two sets in this guide, which suits relaxed, upright conversation.
Best for: entertaining after dark and extending patio season into cooler months. Guests gather around the fire-pit table with drinks, and the L-shaped arrangement keeps everyone facing the flames and each other. It is a natural centerpiece for a backyard that already has room for a gathering area.
Two tables come with the set: one 1400 mm by 701 mm by 279 mm, the other 1001 mm by 599 mm by 429 mm. The fire bowl is 620 mm by 175 mm by 51 mm. Ask the seller which table houses the burner. The lower 279 mm table is the natural center for the fire feature, and the 429 mm table makes a handy spot for drinks. Whichever it turns out to be, use the full table size for planning the footprint, since the bowl measures only the burning area.
The listing specifies an external propane-tank connection, so choose a spot for the tank and hose when you place the furniture. Then follow the manufacturer's manual for clearances, ventilation, and fuel setup. Once those distances are on your plan, you can place the seating with confidence and enjoy the fire safely.
The swivel set: compact comfort for conversation
Not every patio has room for a 3962 mm sectional, and it does not need to. The Costra 4-piece outdoor rope weave swivel sofa set with coffee table in black for 6 brings coastal style to a more modest footprint. A durable aluminum alloy frame and a handwoven rope weave finish give it texture, and high-performance canvas cushions with removable covers make upkeep easy.
The set includes a 3-seater sofa (1930 mm by 770 mm by 610 mm), a 2-seater sofa (1679 mm by 770 mm by 610 mm), and a swivel chair (770 mm by 770 mm by 610 mm). That adds up to six seats, which is where the "for 6" comes from. The cushions are an extra-thick 191 mm, and the seat depth is 729 mm, close to the 737 mm sofa seat depth of the Resaro sectional even though each piece is only 770 mm deep overall. A low 610 mm profile keeps the look open and airy, and it suits a patio where sightlines to a garden or view matter.
Best for: a mid-size patio, a deck, or a side terrace where you want six comfortable seats without a huge footprint. Try the 3-seater along the wall, the 2-seater facing it or at a right angle, and the swivel chair at the open end. The chair rotates 360 degrees, so whoever sits there can turn to the conversation, the garden, or the view. It makes a lovely spot for morning coffee and evening chats alike.
Plan the chair's swivel with a little geometry. A 770 mm square turning around its center sweeps a circle about 1092 mm across, so leave roughly that much open space around the chair, and it will turn freely. Because the sofas are separate pieces, you can also try several layouts on paper. Placed end to end, the two sofas total 3609 mm, or about 3.6 m, and an L-shaped or facing arrangement uses less wall length.
The listing recommends a protective cover during heavy rain, strong wind, or snow, so keep a cover handy to extend the set's life.
Add routes and everyday objects
After placing the sofa, mark doors, steps, planters, storage, and routes to the rest of the property. A walking route of about 914 mm is a comfortable starting point for a mock-up, and you can adjust it for your household and local requirements.
Keep a main path around the seating area where possible, with a smaller reach gap inside it for tables and drinks. Test the plan with the seats full and the door open, the way it will look at a gathering.
Add shade-system bases and any other fixed objects. An umbrella pole or planter takes the same floor space as a chair, so putting them on the drawing early keeps the layout accurate.
Check delivery and care space before ordering
Measure gate openings, turns, steps, and the route to the final spot. Compare the package sizes with that route, and arrange the help the manufacturer recommends for assembly.
Plan a place for cushions and covers. Removable cushion covers, like those on the Costra set, are easy to wash, and a storage spot or a fitted cover keeps the whole set looking its best through the seasons.
Frequently Asked Questions
Are outdoor sofa dimensions usually measured with cushions?
It varies by listing and by field. Check the diagram to see whether a number includes seat cushions, back cushions, or a particular backrest position. When a listing gives both seat height and cushion thickness, ask how they relate, and you will know exactly how high you sit.
Can I calculate a sectional's overall size by adding modules?
Yes, when the manufacturer's connection diagram supports it. Shared corners, overlap, and connector positions affect the total, so use the dimensions of the approved assembled configuration. Individual module sizes are the best starting point for asking about alternate layouts.
How much patio does a deep outdoor sofa need?
Start with the real footprint, then add tables, walking routes, and any operating space. Every patio is different, so the chaise end, a nearby door, or a fire feature often decides how much extra room you want.
How much extra room does a swivel chair need?
Plan for the full circle it sweeps. A 770 mm square seat turning around its center sweeps about 1092 mm across, so leaving that much open space around the chair gives it room to turn through its full 360 degrees.
What clearances do I need around a fire pit?
Follow the appliance manual. It gives the clearances, ventilation, and fuel setup for your model, and those distances, rather than ordinary lounge spacing, set where the seating goes. Once they are on your plan, you can arrange the furniture around them with confidence.
