Before you buy a single sofa cushion, plan the traffic flow. A good layout makes a room feel calm, social and easy to use—no matter the size. These designer-backed rules cover the non-negotiables first, then show you how to apply them to small and large rooms with simple templates you can copy.

Start with flow, then anchor it

Begin by mapping the natural route from the door to the seats and keep that path clear. Once circulation is set, pull the seating into a close conversation group and let a single rug anchor the arrangement. The rug should gather the pieces rather than float under a coffee table. Keep the coffee table within easy reach from every seat and place lighting where people actually sit instead of relying on one ceiling pendant.

Small spaces: soften, lift, streamline

In compact rooms, a gentler outline makes the plan feel generous. Pull the sofa a hand’s width off the wall so it looks intentional, then form a neat U around a low, rounded table. If the room is long and narrow, keep the walkway to one side and slip a slim console behind the sofa for lamps and charging—freeing you from bulky end tables. Mount the TV, use shallow perimeter shelving, and turn deep window reveals into window seats with hidden storage. Two pieces can be enough: a tidy two-seater and a light swivel chair that turns between the view and the screen. Finish with a rug large enough to take the front legs of the seating so the room reads as one space.

Large spaces: make islands, not perimeters

Big rooms feel cosy when furniture floats off the walls. Create distinct zones on their own rugs—a generous conversation area, a quieter reading corner, perhaps a music or media spot. Keep opposing seats close enough for normal conversation; distance makes a cavern. If the ceiling soars, answer the height with a tall bookcase, statement art or an indoor tree so the room doesn’t feel bottom-heavy. Repeat one material or colour through each zone to stitch the whole together.

Let the focal point set the plan

Decide what leads—fireplace, view, or TV—and centre the main seating on that axis. Hang any pendant over the ottoman or coffee table, not randomly in the middle of the room. If you’re juggling a fireplace and a TV, pick a primary and set the other on an adjacent line so you’re not forcing a tug-of-war. Swivel chairs quietly solve the turn-between-both problem without shunting furniture about.

Storage that disappears, tech that doesn’t dominate

Hide storage in plain sight and keep the heart of the room open. Low cabinetry beneath windows, a tall run on the shortest wall to visually widen a long room, and a sofa table as a soft divider will hold everyday bits without stealing floor space. Mount the TV at seated eye level and keep the viewing distance at roughly a sofa-length and a half; it’s kinder on the eyes and the layout.

Light in layers, not in one glare

A single pendant makes a space feel flat. Layer floor and table lamps at seat height, add a wall light where a side table won’t fit, and let the pendant earn its keep by centring it over the table or ottoman. Face seating towards the window where you can, and avoid pushing the sofa onto the same wall as the glazing—you’ll gain brightness and depth at once.

The mistakes to dodge (and how the room looks when it’s right)

Don’t push every piece to the edges, undersize the rug, or let cables, remotes and side tables creep into the walk line. A finished room has clear routes, seats close enough to chat, lamps that switch on where you land, and a single rug that pulls everything together.
