Ventilateur de plafond : bien choisir la taille et le modèle
Quick answer: when choosing a ceiling fan, start with the room size. For areas up to 225 sq. ft. (approx. 21 m²), a 36 to 44-inch (91 to 112 cm) model is sufficient; for larger spaces, opt for 52 inches (132 cm) or more. Install the blades 7 to 9 feet from the floor and at least 18 inches from the walls. For the Quebec winter, choose a reversible model: in clockwise mode, it pushes the warm air trapped at the ceiling back down.
This guide covers size, installation height, motor, energy consumption, and key points to check before purchasing.
What size ceiling fan for my room?
Fan size is measured by its diameter, from blade tip to blade tip. According to the U.S. Department of Energy, a 36 or 44-inch fan cools a room up to 225 sq. ft., while 52 inches or more is needed for larger rooms. If the room is over 18 feet long, two fans perform better than one.
| Room (example) | Area | Recommended diameter |
|---|---|---|
| 10 × 11 ft bedroom | 110 sq. ft. (10.2 m²) | 36 to 44 in (91 to 112 cm) |
| 12 × 14 ft master bedroom | 168 sq. ft. (15.6 m²) | 44 in (112 cm) |
| 15 × 15 ft living room | 225 sq. ft. (20.9 m²) | 44 in, or 52 in for more airflow |
| 15 × 20 ft living room | 300 sq. ft. (27.9 m²) | 52 in (132 cm) or more |
| Open space over 18 ft long | Variable | Two fans |
Calculation: 1 sq. ft. = 0.0929 m², so 225 sq. ft. × 0.0929 = 20.9 m². The Leroy Merlin guide arrives at similar thresholds in metric: 107 cm or less for under 13 m², 107 to 132 cm for 13 to 20 m², and 132 cm or more for over 20 m².
Small 19 or 20-inch models
19 or 20-inch (48 to 51 cm) ceiling fan lights are primarily light fixtures. They circulate air in a small area, such as around a bed or desk, but do not replace a 44-inch fan in a full bedroom.
At what height should I install a ceiling fan?
The U.S. Department of Energy provides four rules:
- Blades 7 to 9 ft (2.1 to 2.7 m) from the floor.
- Blades 10 to 12 in (25 to 30 cm) below the ceiling, never less than 8 in (20 cm), otherwise there is not enough air to circulate.
- At least 18 in (46 cm) between the blade tips and the walls.
- Ceiling at least 8 ft high.
Choosing the mount based on ceiling height
| Ceiling height | Mount type | Calculation |
|---|---|---|
| 8 ft (96 in) | Flush (close to ceiling) | 96 − 10 = 86 in, or 7 ft 2 in below blades |
| 9 ft (108 in) | Short downrod | 108 − 12 = 96 in, or 8 ft below blades |
| 10 ft or more | Long downrod (extension) | Lower to keep blades between 8 and 9 ft |
| Cathedral or sloped | Ball joint or slope adapter | Check manufacturer's maximum angle |
In Montreal plexes and condos with 8-foot ceilings, the flush mount model is often the only one that respects the 7-foot clearance requirement under the blades.
AC or DC motor: which one to choose?
| AC motor (standard) | DC motor | |
|---|---|---|
| Price | Cheaper | More expensive |
| Speeds | Usually 3 or 4 | Up to 6 |
| Noise | Louder | Quieter |
| Consumption | Higher | Lower |
These differences come from the Leroy Merlin guide, which considers a fan quiet if it remains at 36 dB or less at speed 1. For a bedroom, prioritize a DC motor and verify this figure on the technical datasheet.
How many blades are needed?
Most fans have between 2 and 5 blades. The number of blades is less important than the blade pitch (often 6° to 18°) and the diameter, according to the Leroy Merlin guide. Three blades offer a modern look; five blades, a more classic look. Instead, compare the airflow (in CFM or m³/h) indicated by the manufacturer.
How much electricity does a ceiling fan consume?
- Power: 20 to 75 W for most models (Leroy Merlin guide), excluding lighting.
- ENERGY STAR: An ENERGY STAR-certified fan uses about 60% less energy than a standard model, and its components are guaranteed for at least three years, according to Natural Resources Canada.
- With an AC: the fan allows you to raise the thermostat by about 4 °F (approx. 2 °C) without losing comfort, according to the U.S. Department of Energy.
- Turn it off when leaving: it cools people, not the room.
Which direction should the fan turn in summer and winter?
Natural Resources Canada recommends:
- Summer: counter-clockwise (viewed from below). The fan pushes air downward and creates a breeze.
- Winter: clockwise, at low speed. Warm air accumulated at the ceiling flows down the walls without a direct draft.
With electric baseboards, warm air accumulates near the ceiling, especially in rooms with high ceilings. Winter mode requires a reversible motor: check the switch on the housing or the button on the remote control.

Integrated light, remote control, and other options
- Light kit: useful if the fan replaces the only ceiling light in the room. A dimmable light is preferable in a bedroom.
- Remote control: practical for ceilings over 8 feet, as pull chains become out of reach.
- Timer: stops the fan after you fall asleep.
- Outdoor: for a covered porch, the minimum rating is IP44 (Leroy Merlin guide). An indoor model is not suitable.

Installing a ceiling fan in Quebec
A fan is heavier than a ceiling light and vibrates while spinning. The ceiling electrical box must be rated to support a fan; the support's packaging will indicate this. Replacing a light fixture with a fan involves electrical work: read our article installing a light fixture in Quebec: DIY or electrician to find out what the law allows and how to check a master electrician's RBQ license.
Pre-purchase checklist
- Measure the room and calculate the area (length × width).
- Choose the diameter: 36 to 44 in for up to 225 sq. ft., 52 in or more for larger, two fans for rooms over 18 ft long.
- Measure the ceiling height and choose the mount: flush for 8 ft, short downrod for 9 ft, long downrod beyond.
- Check clearance: 18 in between blades and walls, cabinets, or open doors.
- Demand a reversible motor for winter mode, and a DC motor for a bedroom.

Which direction should the ceiling fan turn in winter?
Clockwise, at low speed, according to Natural Resources Canada. In summer, set it to counter-clockwise.
Does a ceiling fan consume much electricity?
No: most consume 20 to 75 W. An ENERGY STAR-certified model uses on average 60% less energy than a standard model, according to Natural Resources Canada.
Can you install a ceiling fan with an 8-foot ceiling?
Yes, with a flush mount model (close to the ceiling). With an 8 ft (96 in) ceiling and blades 10 inches from the ceiling, they remain at 86 inches, or 7 ft 2 in from the floor.
