Choosing the perfect sofa isn’t just about fabric or colour—it’s about proportions. Whether you’re redecorating your living room, furnishing a new home, or simply upgrading your worn-out couch, getting the size and dimensions right can make all the difference between a comfortable, well-designed space and a cramped, awkward one.
If you’re hunting for the best sofas in Perth, start by considering the size and scale of your furniture about the room it will occupy. It’s easy to fall in love with a stunning showroom piece only to find it overpowers your space or doesn’t fit through the front door. Here are five tips to help you make an informed, practical decision before making a purchase.
Start with Room Dimensions
Before browsing styles and configurations, grab a tape measure and assess your space. Knowing the exact dimensions of your room is crucial. Measure the length, width, and height, and note any architectural features such as windows, radiators, door frames, and built-in shelving that could affect where the sofa will go.
One helpful trick is to use painter’s tape or cardboard cut-outs to outline potential sofa dimensions on the floor. This gives a realistic sense of how much space it will take up and whether it allows for comfortable movement around the room.
Pro Tip: Leave at least 75–90 cm of clearance around the sofa to keep walkways and high-traffic areas open.
Understand Sofa Sizes
Sofas come in a wide range of sizes but generally follow some standard dimensions. A full-size three-seater sofa is typically around 210–230 cm long, a loveseat or two-seater is around 150–180 cm, and a single armchair can range from 75–100 cm.
But it’s not just about length, depth and height matter too. Deeper sofas (95 cm or more) offer a more laid-back, lounge-style feel, while shallower ones (80–90 cm) are more formal and upright. Consider who will use the sofa most—tall individuals might prefer a deeper seat, while older adults may want something easier to get in and out of.
Also, don’t overlook back height. Taller backs provide more neck support, but may visually block sightlines in open-plan rooms.
Match Sofa Style to Your Space
Style plays a surprisingly significant role in how a sofa fits a room, visually and physically. For example, low-profile modern sofas with sleek lines make small rooms more spacious, while large, overstuffed traditional styles can overwhelm tighter spaces.
Modular sofas offer great flexibility, especially in large or oddly shaped rooms. A two-seater with slim arms and exposed legs can create an airy, open look for compact apartments or living rooms.
And if you want a touch of luxury or need additional seating without committing to a full sectional, consider a chaise lounge sofa. It’s a stylish and functional addition that adds seating space without a large sofa’s visual or physical bulk.
Consider Traffic Flow and Layout
Once you’ve narrowed down your preferred size and style, it’s time to think about layout. How will the sofa interact with the rest of your furniture, and how will the room flow? This is especially important in open-concept homes or shared family spaces.
Your sofa should anchor the room without disrupting its function. Place it in a way that encourages conversation, provides a clear view of focal points (like the TV or fireplace), and allows people to walk comfortably around it.
Also, consider how other pieces—coffee tables, side tables, or floor lamps—will fit around it. Too tight a fit, and the room feels cluttered. Too spaced out, and it feels disjointed.
Think About Access: Doors, Stairs & Elevators
Many overlook this step until it’s too late: Can the sofa fit into the room? Before clicking “Buy Now,” double-check that the couch will fit through all access points—doors, staircases, hallways, and elevators.
Measure the width and height of entryways and compare them to the packaged dimensions of the sofa. Some sofas come in modular pieces to simplify delivery, but not all.
Also, if you’re in a multi-level home or apartment, take note of stairwell turns and ceiling heights. Professional delivery teams are skilled, but can’t even perform miracles with oversized furniture in tight spots.
It’s All About Balance
Choosing the right sofa size is about balance—balancing comfort with functionality, and scale with style. While trends and aesthetics are essential, the most crucial thing is how well your sofa works in your space and suits your lifestyle.
If you’re shopping in-store or online, don’t hesitate to ask questions or request detailed measurements. Reputable retailers will be happy to help you visualise the perfect fit, whether you’re shopping for compact two-seaters or sprawling family-friendly sectionals.
Remember, your sofa isn’t just another piece of furniture—it’s the heart of your living room. Take the time to find the one that fits just right.
