The ultimate guide to living room clearances measurements, and spacing – everything you need to know to get the basics of your room right

For an interior that’s functional as well as fabulous, knowing essential living room clearances, measurements, and spacing is imperative. Fail to respect them and however stylish the pieces you choose for your room, as a whole the design won’t work.

The best living room layouts create the necessary distances between items of furniture. These measurements provide convenience, permit comfortable movement around the room, and allow each piece to be appreciated.

Wondering what the must-know clearances, measurements, and spacing for living rooms are? We’ve brought them all together here along with advice from designers.

Creating adequate space between the major pieces of living room furniture is essential.

‘For large pieces of furniture, aim to leave about 30 to 36 inches of space between them,’ advises Izabela Tokarski, founder and interior designer at Kabela & Co. ‘This allows enough room for easy movement and creates a balanced flow in the space.

‘If you’re working with tighter quarters, you can go as low as 24 inches, but anything less might start to feel cramped,’ she adds. ‘It’s all about striking a balance between openness and coziness.’

How much room do you need to leave from wall to couch?

Avoid pushing a sofa right against the wall: creating a little space is transformational.

‘We recommend leaving at least 3 to 5 inches of space behind the sofa,’ says interior designer Ally-Catherine Trenary, founder of June St George. ‘This subtle clearance allows for better airflow, protects your walls and upholstery, and prevents the room from feeling too tightly packed. Even a small buffer can make a big difference in how refined and comfortable the space feels.’

How much room do you need to leave from couch to coffee table?

Be aware of how far your coffee table should be from your couch.

‘Your coffee table should be about 14 to 18 inches away from your sofa,’ says Izabela Tokarski. ‘This distance is close enough to easily reach for a drink or book, but far enough to allow comfortable legroom. Keeping it within this range ensures functionality without feeling cramped.’

How much room do you need to leave from couch to side table?

Side tables, because of their position, can be much nearer to a sofa than a coffee table.

‘Put it within 2 to 4 inches so it’s easily accessible but doesn’t crowd the seating,’ suggests designer Evan Clabots, VP of product innovation and development at Cozey.

And while we’re talking side tables, think height, too. ‘Ideally, the height of the table should match or be within 2 inches of the sofa arm for a balanced look and comfortable access,’ says Izabela Tokarski.

How much room do you need to leave from couch to TV?

Always bear in mind the TV’s size to get the correct spacing between it and the sofa.

‘For a 55 inch TV, place it 7 to 9 feet away,’ says Evan Clabots. ‘For a 65 inch TV, 8 to 10 feet away.’ And he adds a general rule to follow: ‘1.5 to 2.5 times the diagonal screen size for comfortable viewing.’

What height should you have your TV?

You’ll want the TV at the correct height, too, to avoid discomfort. Where to position it vertically? ‘The center of the screen should be at eye level when seated, typically 42 to 48 inches from the floor,’ says Izabela Tokarski.

How much room do you need to leave from wall to rug?

As well as the other living room rug placement rules, be mindful of the advice to leave a margin between the rug and a wall. ‘We recommend leaving approximately 12 to 18 inches of exposed floor between the edge of your area rug and the walls,’ says Ally-Catherine Trenary.

‘This border creates a sense of intentional framing and helps define the rug as a distinct design element, rather than allowing it to feel like wall-to-wall carpeting. This spacing also serves a practical purpose: it keeps air vents unobstructed and allows furniture to breathe visually within the room,’ she says.

‘In small living rooms, you can scale the border down slightly, but maintaining some negative space around the rug ensures the room feels open, balanced, and thoughtfully layered, which is an essential part of creating a space that feels elevated yet livable,’ she adds.

How much room do you need to leave from pendant lighting to the floor?

When you’re choosing living room lighting, consider the clearance between a pendant light and the floor as well as other living room measurements.

‘The space between the base of a pendant light and the floor should typically be about 7 feet (or 84 inches),’ says Izabela Tokarski. ‘This ensures enough headroom while keeping the light at an optimal height for illumination.’

For a light above a surface there’s a different way to measure. ‘If you’re hanging the pendant over a table, aim for about 30 to 36 inches above the surface,’ says Izabela. ‘This creates a cozy, well-lit zone without obstructing views or feeling too low.’

You might also be wondering about where art should go when you’re thinking living room measurements. According to Niki Cheng, designer and co-founder of 18th Street Design Collective, the answer to this one is individual. ‘When hanging artwork, keep it at eye level to avoid the common mistake of placing it too high,’ she says.
