The chandelier brings a certain charm and a particular ambiance to the room. This is not always the case when the choice is not suitable. The right method is to take into account key elements such as the layout of the room, its decoration style, etc.
📋 Key points: Personally, I consider the chandelier to be the centerpiece that defines 70% of the visual ambiance of a living room. For me, it is a strategic choice that must balance volume and brightness, respecting a ratio of about 300 lumens per square meter for optimal comfort. A well-proportioned light fixture instantly transforms a mundane layout into an architecturally structured and warm space.
The influence of the room configuration
The choice is varied when it comes to the different shapes and qualities of chandeliers that exist. So, whether it is a design chandelier, a giant chandelier, or another type, the configuration of the space is a very important criterion. Thus, for a large room with a high ceiling, a small chandelier can seem ridiculous and will add no effect to the room. To avoid this kind of mistake, there are interesting tips that can help.

🗣️ My experience: In 2024, I installed a monumental brass chandelier costing 280 euros in a dining room with low ceilings. I quickly realized that people hit their heads every time they got up from the table. The lesson learned is essential: the base of the chandelier must always be located 80 cm above the table surface to combine aesthetics and safety.
The shape of the room
It is based on this criterion that you will have an idea of the shape your chandelier should have. If you want to install it in a large square room, for example, the chandelier can also have a square or round shape, as long as it is quite imposing. In the case where the space is a bit narrow, like in a hallway, a chandelier in the form of a suspension will be suitable.

The size of the room
To ensure the chosen chandelier is neither too small nor too large, a little calculation is necessary. This will help find the ideal diameter for the chandelier. To do this, add the dimensions of the room, namely its length and width in meters. Multiply the result by itself and you will get the diameter of your chandelier in centimeters.

💡 Practical tip: To calculate the ideal diameter of your chandelier in cm, add the length and width of your room in meters and multiply the result by 10. Example: for a room of 4m x 5m, plan for a chandelier of 90 cm.
Height
In the case where there is a table positioned under the fixture, there must be a distance of at least 80 cm to avoid any risk. Otherwise, in general, between the chandelier and the floor, there should be at least 2.15 m.
Table size
It is often in places like the dining room, for example, that the chandelier may be above a table. This should also be taken into account to find the perfect diameter for the chandelier. Indeed, the width of the table should be 30 cm greater than the diameter of the chandelier.
The ideal chandelier depending on the room
| Destination room | Ceiling height | Recommended diameter | Type of lighting |
|---|---|---|---|
| Living room (large room) | 2.50 m and up | 60 – 80 cm | Direct / Indirect |
| Dining room | 2.50 m | 50 – 70 cm | Focused on table |
| Adult bedroom | 2.40 m | 40 – 50 cm | Dim / Soft |
| Entrance / Hallway | 2.50 m | 30 – 45 cm | Clear circulation |
Some chandeliers, due to their shape, brightness, etc., may be better suited to one room than another.
Which chandelier for the living room
Very often, it is the largest room in the house. So you can allow yourself to install XXL pendants, for example. In terms of brightness and design, it all depends on your preferences.

You can opt for models that emit soft light like paper chandeliers. Others, once lit, project beautiful patterns. This is the case with woven chandelier models, for example. Which adds a touch of poetry to the room.
Chandeliers in the dining room
Here, people at the table need to see what is on their plates without being dazzled. Therefore, the suitable chandelier must be able to project its light downward. This way, the table will be well lit. The light should not be too bright either, nor too dim. You can choose a chandelier with lampshades or glass, that would be perfect!
⚠️ Common mistake: Choosing a chandelier that is too small for fear of cluttering the space. An undersized light fixture “floats” in the room and seems lost. It is better to dare a slightly larger model that will structure the overall layout.
Which chandelier to install in a bedroom?
Here, we want dim and soft light. It should inspire relaxation, a cozy atmosphere, and even romance. The chandelier to install in a bedroom should have discreet bulbs. They should not be visible directly from the bed so as not to disturb sleep.
Chandeliers in the office
It is possible to install a chandelier in the office, provided that it does not disturb concentration. Therefore, it should not be too imposing. The accessory should also be positioned so as not to reflect on the room’s screens.
Chandeliers shine in the kitchen too!
Dim lighting is banned in the kitchen and efficiency is prioritized. If you decide to install a chandelier in your kitchen, make sure it can provide generous lighting. If you don’t have a large chandelier, you can choose several pendant lights to hang in various key spots.
🌍 Did you know? The color temperature of your chandelier influences your circadian rhythm. Warm light (2700K) promotes relaxation in the evening, while cool light (4000K) is ideal for concentration in an office.
For the kitchen chandelier, it is important to choose the material carefully. Indeed, it must be washable so that you can regularly remove cooking grease deposits and other residues. Its material must also be durable.

The size of the chandelier, the layout of the room, etc., all of this is important to make a good choice, but it is not enough. For the choice to be truly successful and for your chandelier to bring its little effect to the room, good taste also matters. The chosen accessory must be able to integrate perfectly with the ambient decoration so that the magic happens.
