Ceiling fan: how to choose

Ceiling fan: how to choose

A ceiling fan provides more even comfort and frees up floor space. In addition, many models have a reversible function (summer/winter) .

1) Rule #1: Choose the diameter based on the area (m²)

Leroy Merlin highlights common diameters (e.g., 76, 106, 122, and 132 cm ) and states that the area of ​​the room determines the size of the planks.
As a practical reference by area, this guide helps you decide quickly:

  • Up to 10 m²: 75–105 cm

  • 10–20 m²: 105–120 cm

  • 20–30 m²: 120–132 cm

  • >30 m²: typically >132 cm (or more than one fan)

✅ “UmBox” tip: if you're between two sizes, it's generally worth going up a size (larger diameter = more air with fewer rotations).

2) How many blades? More blades = always better?

Not always. What really matters is the overall design + motor + diameter . Leroy Merlin reports that the number of blades influences the breeze, but the size and space requirements come first.
✅ For practical purchase: don't buy "just by the number of blades"; buy by the correct diameter + motor + noise level .

3) Summer/winter mode (reversible): because it pays off

Leroy Merlin explains the principle: the direction of rotation can help in summer (a feeling of coolness) and in winter to redistribute the hot air accumulated in the ceiling.
This is great in rooms with heating, because it improves comfort without "blowting up" the bill.

4) DC motor, remote control, app, and light: what's worthwhile?

  • DC motor: usually offers higher speed levels and a focus on comfort/noise (highly sought after for bedrooms).

  • Remote control: practically mandatory in the ceiling.

  • Wi-Fi/App: Useful if you want automations (timer, schedules).

  • With LED light: great for replacing a bedside lamp — check if the intensity/color temperature can be adjusted.

5) Installation and safety (important!)

Ceiling fans require solid mounting and proper electrical connection. If you are unsure of the mounting/installation point, call a professional (this type of product can cause vibration and risk due to poor mounting). DECO itself reminds us that there are precautions to take to avoid accidents when using/installing ceiling fans.

FAQ

What is the ideal diameter for a ceiling fan in my living room?
It uses the area (m²) as a basis: for example, 20–30 m² usually requires 120–132 cm.

Is a ceiling fan suitable for winter?
Yes — if it's reversible, it helps redistribute the hot air near the ceiling.
