A chandelier that is too small looks lost over a dining table, and one that is too big crowds the room. The good news: you don't need a designer to get it right. Three simple rules, all in centimetres, will give you the right size for almost any UK dining room.
Quick answer
For most UK dining rooms, a chandelier between 50 cm and 75 cm wide is the right size. It should be about half to two-thirds the width of your table, and the bottom should hang 75–90 cm above the table top.
Rule 1: Size it to the room
Add the length and width of the room in metres, then multiply by 8. The answer is a good chandelier diameter in centimetres.
- 3 m × 3 m room: 6 × 8 = about 48 cm
- 4 m × 3.5 m room: 7.5 × 8 = about 60 cm
- 5 m × 4 m room: 9 × 8 = about 72 cm
Treat this as a starting point. Open-plan kitchen-diners usually look better with a light sized to the dining area rather than the whole space.
Rule 2: Size it to the table
If the chandelier hangs over a table, the table matters more than the room. Choose a chandelier that is half to two-thirds the width of the table. For a typical 90 cm wide table, that means a chandelier around 45–60 cm across. Keep at least 15 cm between the edge of the chandelier and the edge of the table on each side, so nobody bumps their head when they stand up.
Long or rectangular table? A single round chandelier can leave the ends of the table dark. Either choose an oval or linear light, or hang two smaller pendants in a row.
Rule 3: Hang it at the right height
- Over a dining table: leave 75–90 cm between the table top and the bottom of the chandelier. Close enough to feel intimate, high enough not to block the view across the table.
- Higher ceilings: for every 30 cm of ceiling height above 2.4 m, raise the chandelier by about 7–8 cm.
- Not over a table (hallways, landings, the middle of a room): keep at least 2.1 m clear between the floor and the bottom of the light so people can walk underneath.
Many UK homes have ceilings around 2.4 m. If yours are lower, or you have a busy walkway, a flush or semi-flush ceiling light gives you the sparkle without the head-height problem.
Matching the style to the room
- Statement and modern: the Astra 8-Light Sputnik Chandelier is 72 cm across - ideal for a larger dining room or a stairwell.
- Glamour and sparkle: the Celeste Crystal LED Chandelier comes in sizes from 40 cm to 100 cm, so you can match it exactly to the rules above.
- Long tables: the Alabaster Marble Chandelier comes in round or oval, from 45 cm up to 150 cm - the oval is made for long dining tables.
- Country and traditional: the Lumière Noir French Country Chandelier is 58 cm wide with an adjustable chain.
- Soft and natural: the Bamboo Rattan Chandelier (45-60 cm) suits Japandi and relaxed rooms.
- Low ceilings: the Eliza Crystal Flush Mount Ceiling Light sits close to the ceiling, from 22 cm to 80 cm.
Before you buy: fitting and safety
Chandeliers are hardwired to your lighting circuit, so they should be fitted by a qualified electrician. Larger and heavier pieces also need a ceiling fixing strong enough to hold them - ask your electrician to check this before installation. In England and Wales, some electrical work falls under Part P of the Building Regulations, and a registered electrician will handle this for you.
Frequently asked questions
How do I work out what size chandelier I need?
Add the room's length and width in metres and multiply by 8 to get the diameter in centimetres. If it hangs over a table, choose a chandelier half to two-thirds the width of the table.
How high should a chandelier hang over a dining table?
The bottom of the chandelier should be 75-90 cm above the table top. Raise it slightly for ceilings higher than 2.4 m.
Can I put a chandelier in a room with a low ceiling?
Yes, if it hangs over a table where nobody walks underneath. Otherwise keep 2.1 m of clearance from the floor, or choose a flush or semi-flush ceiling light instead.
Do I need an electrician to fit a chandelier?
Yes. Chandeliers are hardwired, so they should be installed by a qualified electrician, who can also check the ceiling fixing can take the weight.
