A few minutes with a tape measure protects your room flow and helps avoid delivery day surprises.
Room dimensions
Measure width, depth, and the wall where the sofa will sit. Note windows, radiators, and outlets.
Clearances
Plan for about 18" between sofa and coffee table. Keep 30" to 36" clear for main walkways.
Traffic flow
Make sure the sofa doesn’t block doors or high traffic routes, especially in smaller rooms.
Delivery path
Measure doorways, stairways, and turns, including elevators, so it can actually get inside.
Sofa size is not just length. Seat depth, seat height, and arm style shape how a sofa feels day to day.
Deeper seat (loungier)
22"–25"
Great for taller individuals, lounging, and relaxed posture.
Shallower seat (upright)
20"–22"
Comfortable for shorter individuals and conversation focused seating.
Higher seat height
18"–20"
Easier to get in and out of the sofa and supportive for longer sitting.
Lower seat height
16"–18"
Feels more casual and lounge like, ideal for low profile rooms.
Slim arms
More usable seat
Ideal when you need maximum seating width in a smaller footprint.
Wide arms
Statement feel
Adds visual presence, but reduces interior seat width. Plan accordingly.
Softer cushions
Relaxed lounge
Best for sinking in and casual comfort. May need more fluffing over time.
Firmer cushions
Long sitting
Supportive for daily use and posture friendly comfort.
Tip: If you are between sizes, the right choice is usually the one that preserves walkways and lets the room breathe. Scale first, then comfort details.
Visual Balance
Balance your sofa with other large furniture pieces like bookshelves, TV stands, and armchairs. The goal is a cohesive scale. Nothing feels dwarfed or oversized.
Height Matters
Make sure your sofa height works with coffee tables and side tables. A low-back sofa can look awkward next to a tall side table and vice versa.
Testing the Comfort
Taller individuals may prefer a deeper seat (22"–25") and higher seat height (18"–20"). Shorter people may prefer a shallower seat (20"–22") and lower height (16"–18"). Consider armrest height and cushion firmness based on how you use the sofa.
