Standard Sofa Dimensions Australia: Sizes, Seat Depth and Fit

Real sofa dimensions from Australian product listings

The table uses the named configurations and published assembled dimensions checked on 1 October 2026. All measurements are in centimetres. A different model, configuration or product revision may have different specifications, so confirm the selected listing before ordering.

On a phone, swipe the table to see each column.

Read the labels as carefully as the numbers. The DEXTER listing also gives a box/component size of 207 × 100 × 102 cm, which is different from its assembled size above. “Product dimensions” and “packaging dimensions” should have separate places in your notes.

These examples are a starting point for comparison. They do not show the smallest or largest sofa available in Australia, and the seating names are not a promise of a particular amount of space per person.

Know which measurement you are reading

Retailers usually provide width, depth and height, but diagrams are useful for understanding exactly where each line starts and finishes. Keep the labels with the numbers when you copy them; a bare “220 × 100 × 85” is easy to misread later.

• Overall width: the outside side-to-side dimension, commonly measured from the outer edge of one arm to the other.
• Overall depth: the frontmost-to-rearmost dimension, including the sofa back rather than just the sitting surface.
• Overall height: the floor-to-top dimension specified by the maker. Check whether the drawing includes loose back cushions or an adjustable headrest.
• Seat depth: the usable front-to-back sitting area identified in the product drawing.
• Seat height: the listed floor-to-seat measurement. Your experience of it also depends on how the cushion compresses when you sit.

Use one unit throughout your plan. Divide millimetres by ten to convert to centimetres: 2,280 mm is 228 cm. A small transcription error can become a very awkward delivery problem.

Compare sitting space separately from outside size

The KIVIK three-seat example makes the distinction clear: its published overall width is 228 cm, while seat width is 180 cm. Its overall depth is 95 cm and seat depth is 60 cm. The furniture footprint includes substantial space beyond the part you sit on.

Arm shape, back construction and cushion arrangement all affect the relationship between outside size and usable space. When comparing two sofas, note how many people you want to seat comfortably and how you use the lounge. Reading upright, stretching out alone and sitting with visitors place different demands on the same footprint.

Where possible, try the sofa in the position you normally use. Notice whether you can sit back comfortably, where your feet rest and whether getting up feels easy. Seat depth alone cannot tell you how a cushion, back angle and your own proportions will work together.

If shopping online, ask for missing seat measurements rather than estimating from photographs. A room image can make a deep sofa look compact, especially when the surrounding furniture provides little sense of scale.

Draw chaise and corner sofas from above

A chaise sofa needs a plan-view sketch. Mark the full width across the back and the maximum projection into the room, then draw the shorter-depth section too. A single rectangle is useful as a bounding box, but the actual L-shaped outline shows where walking space remains.

For the KIVIK chaise example, the maximum footprint is 280 cm across and 163 cm deep. The shorter section’s overall depth is 95 cm. Those figures describe this particular layout; they are not interchangeable with a standalone chaise or another configuration in the range.

Check the retailer’s diagram before choosing “left-facing” or “right-facing”. Confirm which viewpoint the retailer uses and which side the chaise occupies in your intended room. Do not rely on a thumbnail that might show an alternate arrangement.

For modular sofas, save the component plan as well as the combined dimensions. Ask which sections separate for delivery, how they connect and whether a selected configuration can actually be rearranged. A modular label does not tell you which joins are intended for routine changes.

Test the footprint in your actual room

Use removable floor-safe tape or a paper template to mark the proposed outline. Check that the marking method will not damage your floor. Put the outline where the sofa will really sit, allowing for skirting, curtains and anything that prevents it sitting directly against the wall.

Then use the room. Walk from the entry to the next doorway, pull out the dining chair nearby and open cupboards. Check the path around a coffee table and whether the chaise blocks the route everyone takes. Keep exits and necessary access clear.

Include the space the furniture needs while operating. A recliner, sliding seat or sofa bed has a larger working area than its closed footprint. Get the operating dimensions and wall-clearance instructions for the exact model. Follow heater and fireplace separation instructions independently.

For a sofa bed, consider the room with the bed open and the coffee table moved somewhere realistic. For a recliner, include access to its controls and power arrangements. The best footprint is one that works during use as well as in a photograph.

There is no clearance figure in this guide that establishes building or accessibility compliance. If accessible circulation is a requirement, plan around the user’s needs and obtain appropriate professional guidance.

Check the whole delivery route

A couch can fit beautifully in the lounge and still fail at the stair landing. Measure the route from the unloading point to the final position, including access restrictions at apartment buildings.

1. Doorways: record the clear opening with the door in its available open position, plus the opening height.
2. Hallways: measure narrow points, corners and the approach space needed for a turn.
3. Stairs: include width, landings, turns, handrails and overhead obstructions.
4. Lifts: check the door opening and usable cabin dimensions, plus any building booking requirements.
5. Furniture components: obtain the largest indivisible part’s dimensions and the delivery packaging details.

Ask the supplier what can legitimately be removed or disassembled. Do not assume the arms come off because the feet do, or that delivery staff will dismantle the furniture on arrival. Confirm who handles any authorised assembly work.

A doorway measurement alone cannot prove that a large object will turn a corner. If the route is tight, send measurements and photos to the retailer or removalist and request an access assessment before committing. Also check the seller’s delivery conditions and what happens if access fails.

Measure again when choosing a sofa cover

Furniture dimensions describe the object; cover measurements describe the fabric or fitted shape you need. Start with the cover format, then measure the relevant areas. A fitted upholstery replacement, a draped throw and separate seat pieces require different information.

Our loose-cushion measuring guide helps you record the individual dimensions. The Sofa Cover Fit Lab can help organise the choice, but the selected product’s shape and sizing instructions remain the final check.

Your pre-order measurement checklist

• Exact model, upholstery and configuration recorded
• Overall width, depth and height checked against the labelled diagram
• Seat dimensions checked for the way you intend to sit
• Chaise orientation and individual module sizes confirmed
• Room footprint and operating space tested
• Largest delivery component and packaged dimensions obtained
• Doors, turns, stairs and lifts checked along the entire route
• Any uncertain access reviewed by the delivery provider
• Cover measurements recorded separately, if buying a cover
