Knowing how to design a dining room comes down to one piece of furniture and the space around it. Get the table the right size and centred, leave enough room to pull a chair out and walk behind it, then layer in lighting, storage and finishes, and even a modest London dining space feels generous and inviting. This guide works through the decisions in the order that matters, so the room functions for a quiet weeknight supper and a table full of guests alike.
It sits alongside our other room-by-room guides, including how to design a living room and how to design a kitchen, and the practical interior design cost guide for London.
Start with how you actually use the room
Before choosing anything, be honest about how the room will be used. A formal dining room reserved for hosting is planned very differently to a table that doubles as a homework desk, a home office and the place the family eats every night. Decide how many people you need to seat day to day, and the maximum you want to host, because those two numbers set the size of the table and therefore the whole layout. In many London homes the dining area is part of an open-plan kitchen or living space rather than a separate room, which changes the job from filling a room to defining a zone within one.
Size the table and the clearances
The table is the anchor, and clearance around it is the rule most people get wrong. As a working guide, allow about one metre between the edge of the table and the nearest wall or furniture, so a diner can push their chair back and someone can pass behind them. Allow roughly 60cm of table width per place setting so guests are not bumping elbows. A round or oval table seats people more sociably and is easier to move around in a tight space, while a rectangular table suits a long, narrow room and bigger numbers. If you entertain occasionally, an extendable table gives you everyday compactness with the option to grow.
Lay out the space and zone it
Once the table size is fixed, position it centrally in a dedicated room so the circulation space is even on all sides. In an open-plan layout, the dining zone needs defining rather than centring: a rug sized to sit under the table and chairs even when pulled out, a pendant light hung over the table, or a change in flooring or a low sideboard all signal where the dining area begins and the kitchen or sitting area ends. Keep a clear route between the table and the kitchen, since that is the path you will walk most carrying plates.
Get the lighting right
Lighting is what turns a dining area into a dining room. A statement pendant or a pair of pendants hung centrally over the table is the anchor; hang it low enough to feel intimate, usually around 70 to 90cm above the tabletop, but high enough not to block sightlines across the table. Put the pendant on a dimmer so the same room can be bright for a working lunch and soft for dinner. Layer in wall lights, a lamp on a sideboard or candles for warmth, and avoid relying on a single bright ceiling spotlight, which flattens the room and is unflattering over food.
Storage and the sideboard
A dining room earns its keep with storage. A sideboard or a run of low cabinetry holds glassware, serving dishes, linen and candles, keeps the table clear, and doubles as a surface for serving or for a lamp and flowers. In a period London home, built-in storage in an alcove can add function without crowding the floor; in an open-plan space, a sideboard helps zone the dining area as well as store things. Think about what you actually need to put away within reach of the table, then size the storage to it.
Seating, surfaces and colour
Comfortable seating is what keeps people at the table after the plates are cleared. Upholstered or padded chairs are kinder for long meals than hard ones, and a bench on one side can seat more in less space and tuck away neatly. For the table surface, choose for the life it will lead: a sealed or solid timber takes daily wear, while a more delicate finish suits a formal room. With colour, dining rooms are a good place to be a little bolder than the rest of the home, since you spend evenings there; deeper, warmer tones feel intimate by lamplight. Tie the scheme to the adjoining space if the room is open-plan, so the zones read as one home.
Common mistakes to avoid
- A table too big for the room: it looks impressive empty but leaves no room to move once chairs are out. Measure the clearances first.
- The pendant hung too high or off-centre: centre it over the table, not the room, and hang it low enough to feel intimate.
- One harsh ceiling light: a single bright downlight is unflattering. Dim and layer instead.
- A rug that is too small: chairs should stay on the rug when pulled out, or it will catch and look mean.
- No storage: without a sideboard the table becomes the dumping ground, and the room never feels finished.
Bring it together
Design a dining room in the right order, table size and clearances first, then layout and zoning, then lighting, storage and finishes, and the room feels both practical and welcoming.

Frequently asked questions
How do you design a dining room layout?
Start with the table. Choose its size from how many people you seat day to day and want to host, then position it so there is about one metre of clearance on every side to pull chairs out and walk behind them. In an open-plan space, define the dining zone with a rug and a pendant light rather than centring the table in a whole room. Only once the layout works should you choose finishes.
How much space do you need around a dining table?
Allow roughly one metre between the edge of the table and the nearest wall or furniture, so a diner can push their chair back and someone can pass behind. Per place setting, allow about 60cm of table width so guests have elbow room. These clearances matter more than the table size itself in a compact London room.
How big should a dining table be for my room?
Work back from the clearances. Measure the room, subtract about a metre on each side for circulation, and the space left is the largest table that will work. Then check it seats the numbers you need at roughly 60cm per person. If you host only occasionally, an extendable table keeps the room workable day to day and grows when needed.
What is the best lighting for a dining room?
A central pendant or pair of pendants over the table, hung around 70 to 90cm above the top and on a dimmer, is the anchor. Layer in wall lights, a sideboard lamp or candles for warmth, and avoid a single bright ceiling spotlight, which flattens the room and is unflattering over food. Dimmable, layered light lets one room suit both lunch and dinner.
How do you design a dining area in an open-plan space?
Define it rather than centre it. Use a rug sized to sit under the table and chairs, a pendant hung over the table, and a sideboard or a change in flooring to mark where the dining zone begins. Keep a clear route to the kitchen, and tie the colours and materials to the adjoining areas so the whole space reads as one considered home.
