01 / Measure the couch you own
Use the outside dimensions.
Measure the widest overall width, deepest overall depth, and highest point. Include arms, projecting backs, and feet that stay attached. Seat width is not the same as the couch's full width.
For a sectional, sketch the actual L shape and measure each section. A single rectangle around it can hide the empty corner or overstate the space it occupies. Keep the assembled footprint for room planning and the individual pieces' dimensions for delivery.
02 / Check the usable wall
Do the small calculation first.
Measure the available wall segment between the things that limit placement. Record radiators, fixed cabinets, door openings, and other projections. A wall's full length may be greater than the space you can actually use.
120 in − 84 in = 36 in
That is the total width left around a 7-foot couch on a 10-foot wall. Centered, it leaves 18 inches at each end. A side table uses some of that same space.
The calculation checks width only. It does not prove that the room has enough depth, the door opens, or the couch can get upstairs.
03 / Put the whole room together
Draw what stays around it.
Add the couch's width and depth to a measured plan, then place the table, desk, shelving, and other pieces you intend to keep. Mark the door swings and the paths you actually use.
- Can you open the room door and any nearby cupboard or drawer?
- Can you reach the seating without stepping around a table every time?
- Is there space for the way you use the room, including any mobility aid or other access need?
Try the couch on a second wall before deciding it must go. An item that works in one arrangement can obstruct another.
Choose clearances for your actual needs and confirm any applicable requirements separately. A “fits” label on a simple floor plan is not an accessibility certification.
04 / Check the route in
The last turn can be the tight one.
Measure clear openings along the delivery route, including the building entrance, apartment door, narrow corridor, stair turns, landings, and elevator door and cabin if relevant. Note the space on both sides of each opening so you can assess turning.
A single doorway width or diagonal is not enough to guarantee that a three-dimensional couch will pass. Use the dimensions of the piece as transported, including packaging and any parts that can actually be removed. For a tight route, give those measurements and photos to the mover or delivery team before booking.
