What should I measure before buying a sofa online?

The wall or zone where it will sit, plus the full delivery route: every doorway, hallway, stair turn and elevator. Compare those against the sofa's assembled dimensions and its boxed shipping dimensions.

Which delivery option should I pick if I live upstairs?

Choose a service that carries the sofa into your room. Castlery's Room of Choice covers up to two flights of stairs for $50–$70; Article's In-Room delivery brings items to the room you choose; Albany Park's White Glove is $149.

How much space should I leave around a sofa?

As a rule of thumb, keep about 30–36 inches for walkways and 14–18 inches between the sofa and a coffee table. Treat these as starting points, not rules.

How to Choose a Sofa for a Small Space

In a small room, the sofa decides everything: how you walk through the space, where the light falls, whether the room feels calm or cramped. Buying online adds one more risk. The sofa has to get through your door before it can fit your room.

Here’s a step-by-step way to choose one that fits both.

1. Measure the zone, not just the wall

Mark the sofa’s footprint on the floor with painter’s tape and live with it for a day. Then check:

Walkways: as a rule of thumb, keep about 30–36 inches where people walk.
Coffee table gap: about 14–18 inches lets you reach a drink without bumping knees.
Doors and windows: make sure nothing swings into the sofa or blocks a radiator or vent.

2. Measure the route in

This is where online furniture purchases go wrong. Measure every point the sofa passes:

Front door and apartment door width
Hallway width, especially at turns
Stairwell width and the clearance at each landing
Elevator door width, plus interior depth and height

Compare these with the product page’s boxed shipping dimensions as well as the assembled size. A sofa that ships in several boxes is far easier to get up a narrow stair than one that arrives in one piece.

3. Choose the right scale

Small rooms reward sofas that look lighter than they are:

Slim or track arms give you more seat width for the same overall length.
Visible legs show more floor, which makes a room read as bigger.
A lower back keeps sightlines open, useful if the sofa floats in the middle of the room.
Seat depth is personal: deeper seats suit lounging but take more floor. Sit on something similar in a store if you can.

4. Pick a delivery level that matches your building

If you live upstairs or can’t carry heavy boxes, pay for a service that brings the sofa into your room:

Brand	Into-the-room option	Published price
Article	In-Room or White Glove	Shown at checkout
Castlery	Room of Choice (up to 2 flights); White Glove adds assembly	$50–$70; $100–$150 (min. $1,399 spend, selected cities)
Albany Park	White Glove	$149 (ground shipping is free)

5. Know the return cost before you buy

Small-space mistakes are usually about size, and returns aren’t free. Castlery and Albany Park both charge 20% on returns; Article reduces your refund by shipping fees instead. Castlery doesn’t accept returns of customized pieces, so be certain of dimensions before choosing a custom configuration there.
